SharkBite Fittings - Awesome or A Failure Waiting To Happen? 

I know these are for indoor use, but I do have a personal experience. I have have 2 of these outside to hook up my water to my sprinkler system, these things have been out in the weather in Canada and I am so impressed with how, even exposed to the worst elements and temp swings these things are holding up, and they have been outside like this for 10 years now connecting copper pipe!

Thank you for not adding music and splash screens, and thereby trying to be a movie star. The clear, no-nonsense explanation that you gave us is exactly what we needed.

These have been used in other parts of the world for way longer than 15 years. Their success, like anything building related, relies on the prep. I always clean the pipe and use some plumbing grease before I put one in. Been using them since they came to market here and did a hot water line repair in a kitchen wall the day the we're available. Fast forward around 15 years later. Same area had a leak in the wall again. Had to go in and open everything up, I stated to think it was that SharkBite fitting and panicked a little. Upon inspection, come to find it was another section of pipe on the cold side that was deteriorated. The SharkBite still looked good and didn't show signs of any leaks or compromise. We went ahead and disassembled our old repair and made a much more extensive repair job out of the whole situation. When I got to inspect the fitting itself the o-ring was slightly flattened but showed absolutely no signs of deterioration. The grease really does protect the o-ring. This is why I say prep your stuff right and you won't have the problem to begin with!

We used one in the basement at our water reservoir building for a city for a chlorine analyzer and it still works like a charm to this day! That was like 2007

I was a plumber for over 12 years, and for the last 10 years I've worked in the largest independent plumbing supply house on the east coast. I have installed hundreds, and sold thousands of these fittings. The only way these things fail are hydraulic pressure from freezing or poor instalation. As long as the pipe is clean cut at a 90 degree angle, smooth and completely round where the o-ring will make contact with the pipe, fully inserted, and deburred you will not have any issues with this product. This isn't new technology, just perfected, Delta had these things back in the 80s they were much bigger and made of plastic except for the teeth, they just weren't removable. In 10 years of selling them only 2 or three have been returned to my store, but not for credit, they were returned by plumbers during a freeze, showing how hard these things were trying to hold onto the pipe before tearing the brass apart very similar to the one that failed in this video. There's not much out there that can compete with the hydraulic pressure of freezing not even cast iron. The brand I sell is tec-tite which has a warranty of 50 years, that is better than most pipe manufacturers so I'll let you decide from my experience. Good luck guys!

Matt, thanks for putting out the content for your channel. I'm installing a water softener and this is my first real dive into plumbing. But I checked out the other content on your channel and it's all great! You explain stuff perfectly without too much chatter. Consider me a new subscriber!

I don't see any reason why there would be any thumbs down. I found this video to be helpful and honest review.thank you.

10 years ago I used a shark bite valve for my water main. I would have Soldered a valve in however that valve at the street would not turn off entirely so solder was a no go. The shark bite saved the day and is still going strong.

To help prevent them from leaking, it's important the section of the pipe going into the fitting is clean and smooth, not marked. Equally important too, the pipe must be cut square, so a proper pipe cutter of sorts should be used. When used on copper pipes, clean up any sharp edges after cutting. I've used them several times and only had leaks on pipes that weren't cut square. Also not mentioned by Matt in the video clip, once the fitting is pressed onto the pipe, they can be twisted around to the right orientation without leaking. I've even done this while the connection was under pressure and it didn't leak.

These particular fittings may only have been on the market for 20 years (15 mentioned in the video, dated 5 years ago), but I used equivalents, in the UK and in France, 32 years ago. Only one has failed in that time and that was due to freezing pushing the pipes apart - the stop-cock was off, so there was no flooding when it thawed.

Very informative. Thank you Matt. I am replacing an RV 6 gallon water tank with a heat on demand water heater. My camping trailer is on a permanent site with very good well water (no city additives) and all fittings readily accessible. Until today I had never heard of SharkBite fittings. They are going to make my job a whole lot easier.

Thank you for this video. It's very helpful to be able to see and understand how something functions rather than a simple 'just take our word for it' approach other people tend to use.

I've heard stories of these failing, never seen one fail myself, though. I follow Matt's advice and don't put them where I can't see them. Another advantage of them is that the pipe doesn't need to be empty. If you can't clear the water from a pipe, soldering the joint will be very difficult. These will work no matter what.

Thank you Matt. I used Sharkbite fittings on PEX, copper, and PVC tubing as part of a Tankless Water Heater install done in 2005. They've been rock solid since, even on the heater hot-water outlet side where there is a 90 degree Sharkbite elbow between copper pipe on the heater side, and PEX for the run into a 27 gallon buffer tank / heat exchanger for an underfloor heating system that is heated by the Tankless heater (in addition to providing domestic water). The tankless water outlet setting to the buffer / heat exchanger is 160 deg and the sharkbite fitting right under the heater has been fine. That said, all of my Sharkbites are visible for inspection. Thought my experience has been excellent with Sharkbite fittings, I think your recommendation to use more permanent connections inside of walls is a sound one. Not only are soldered (Copper) or crimped (PEX) fittings way less expensive than Sharkbite, but local codes might not support the Sharkbite inside walls.

I am sold on the Shark bites! We put a new well pump and due to the water pressure increase, some old connectors developed small leaks. I replaced those old connectors with Shark Bites. So easy to install and perfect, no leaks. Some of those old copper pipes looked rather bad and I was worried they might leak, but everything is holding up great! Good product!!

Thanks for making a vid on these, the side-cut, and the stress test. I was installing an icemaker line and when I was sizing the shutoff valve at the wall, it had actually been ever so slowly dripping under the knob down into the crawlspace. I'm unsure for how long, but thankfully there was a plastic box and the drip traveling the tube didn't seem to be hitting any insulation or wood. I went and got a SharkBite shut-off valve, a pex cutter, and a removal tool in case I didn't cut it right. Quick, solid, fix and beats a $60-$90 dollar pex crimp tool a non-plumber may rarely use. Hooked up the feed line to the back of the fridge. Good to go. :)

One other great use for the noon plumber in some situations you don't know if you have completely shut off the water. An open shark bite ball valve can be jamed on and then closed and you now have control over the water again. In appartments generally the water shut off is a long way away and the shut off for the shower valves are old and only partially work.

You got it right, I use them in any area I can access, emergency temporary repairs and the are great in mobil home repairs

Thank you, Matt, I enjoy watching your channel. I bought one shark bite Angle stop to replace a toilet water valve - purchased the right angle stop valve to replace an old compression fitting. Its outside the wall so i feel this will be in clear visible view for any leaks. again, appreciate all the information you provide in the home building and remodeling world. Burt Vickers Houston Texas.

I carry them as a first aid kit for household pipes , I’ve never drilled a pipe , but have seen plenty of accidents over the years , in that application , they perfect !

I agree 100% with you. I only install these in the open where I can see them NOT hidden behind a wall.

I have never had a Sharkbite fail ! I worked for Home Depot and had my doubts, but I used a lot of them and they are great!

I appreciate this video and the mix of pros and cons comments. I feel comfortable with our plumber's choice to use behind our water heater.

I’ve only used one inside a wall once in all my years, as we had little choice due to the circumstances with this particular house. This fact STILL keeps me up at night now almost eight years later.

I used to work for a bathroom renovation company, we used the shark bite caps over and over again as a temporary cap off during demolition. We had the same 10 or so caps and used them for around 12 months before replacing them with new ones. Not one ever failed.

Make sure the pipe is cut at 90 degrees and "they MUST push on 1 full inch" (mark the pipe at the 1 inch spot to be sure) and they are great. But I would only use them where you have easy access. Great for DIY water heater replacement, that's what I used them for. Great video as always.

Awesome review. About to upgrade my crawl space plumbing from 1/2” to 3/4” The supply is 3/4”. This video has just made my mind up. Thank you

I used a bunch to install a whole house water filtration/softener/sanitizer system, with a bypass line, in a viewable area several years ago, and so far so good.

Installed thousands No problems at all Seating the fittings fully is key 🔑

I’ve been using these since they first came out, they’re superb. I’m a maintenance engineer, so as they’re very expensive I wouldn’t use them for an install. My first purchase was of a bucket of various 15mm and 22mm tees, elbows and straights, at the time a comparable bucket of soldered end feed fittings was £25, my bucket of Techtite cost £170. Now that’s a huge difference I’ll admit, but they are totally worth it. Imagine when you’re on call, I’ve had a middle of the night call out, water pouring through a ceiling. I turn up, get my copper cutters, cut the pipe and bang a cap end on, bingo, water stopped and I’ll come back in the morning and carry out a proper repair. Or, I’m on site and need to carry out a quick repair, no “hot works permit” required ( which can easily take an hour to get ) no waiting 45 minutes after last soldered joint, just get on and be on my way. The other bonus is you can use them if there’s water still passing an isolation valve or water standing in the pipe rendering the soldering option impossible. If you a maintenance engineer have some 15/22/28 straight connectors, elbows, tees and cap ends in your tool box, you won’t regret it.

One more option to put in the toolbox... I'm glad I know how to do it every other way... I cannot believe how many people don't know how to solder correctly.. but it's really good for business... Push connect .. not bad . I believe. Will wait and see what happens...

I discovered the PVC/Copper coupling when replacing my well pressure tank. After spending 2 hours trying to get the 1" copper pipe hot enough to properly solder and still getting leaks, I went the PVC route, with the Sharkbite as the transition to the existing copper. Literally done in 30 minutes. Sure, it was $18, but well worth it in eliminated frustration.

They may be relatively new to the consumer market, but the push to terminate type fittings have been around for quite a long time now in industry. I have personally used them in industrial settings for over 2 decades now and have found them to be quite reliable, and in far harsher conditions than any home would subject them to.

As a Plumber (going on 30 years) I believe that "quick & easy" fixes with these fittings", are great for the inexperienced homeowner. However, the professional should always make the best repair possible re: replacement of section with soldered fittings. Great for temporary fixes, capping, etc.

Great review of push fitting. I installed a double-water heater (back to back water heaters) under the house using push fittings and it worked great. Not worried about location because of our drainage system under the house (previous water heater burst and there was no water under the house). Replacing a water heater in a laundry room this week and even though I can see the fittings, I think I'll stick with crimp fittings for this install. Thanks.

Great video, great sound, no giggling of the camera. I also liked how you split the fitting to show what was inside. I was a truck driver, and I drove Volvo trucks. Volvo uses these type of fittings on the plastic air hoses for brakes, air bag suspendon, even to the air seat. I have had 3 fail on me. one to the seat, and two for the air ride system. When I had to do some plumbing repairs to my house I knew I was going to use solider, copper fittings and pipe.

I have used them alot under my house. And I found that even in a freezing environment they held up very well.

These types of fittings are used in industrial environments, and all over the place. they're great. Just need to watch out for the pitfalls of them, which is, improper initial fitting

This video is great for someone like me who just bought a first home, and is handy but doesn't have much solder/plumbing experience. I plan to replace the (possibly leaky?) compression valves for my washer inlet with 1/4 turns, but I'm going to have to do a lot more research as it's indoors and I need to cut through the drywall. I appreciate the logical/critical info. Thanks for the video!

I love the no-nonsense approach to this video. No time wasted here. Subbed

Ive got limited experience with em but they've been LEGENDARY when I've used them

Great video. I used these to install a water heater. Simple and worked great!

I used a similar product (I think it was called prestolok) for 1/4 and 3/8 tubing (similar to pex) in pneumatic applications in manufacturing equipment in the '80s and never had a blow out unless someone didn't install it completely. So I was really excited to see sharkbites in the store in about 2009. I have always been nervous about the lack of time testing and hesitate to use them in a closed location like a wall or between floors however, I have when the location was really tight and the only option was to destroy the room. That has been quite some time but again, only time will tell. Thanks for the analysis.

Have used them a couple of times. They worked great.

I am a facilities manager. I have 44 water heaters installed, all with sharkbite fittings and valves. About 10 fittings per installation. Some have been on for as long as 12 years. Not one drop of leakage, nor one grain of salt creep (high mineral content in our local water). They have, at least up to 12 years, had 100% reliability.

Good video Matt I’m a38 year master plumber , I agree with not using them everywhere but I have been using the more in the last 3 to 4 years for hose bibs wth pex and making a loop in the stud space , that way anyone can pull the hose bib out and change it with no special tools such as the Uponor expansion tool I could use . Guess I’m taking away my call back work ha ha . well in about 3 more years I’m throwing in the towel. I also use them if I run out of pex fittings that go from pex to copper comes in handi . One other place. Water filters and pressure booster pumps they make great unions since you can turn them . Ive used these in quite a few applications like that and have not had any issues . Although I would agree for everyday plumbing and heating piping Pex expansion or Solder or propress . Thanks for your sharing and contribution to the trades.

I only use these for temporary connections during remodel so I still have water while I work on walls and floors in a wet room or kitchen. Once I run all the new pipe and walls and floors are done, I can shut off the water and properly glue all pipes and connect to fixtures. Bought a house that had all the copper stolen but the bit of pipe from the one toliet in the house was copper and the meter was still connected in the work shop. I was not ready to run a full plumbing job yet since the house needed gutting but we needed to use the toilet and sink to wash so I temporarily connected some cpvc straight run from the meter just under the bathroom floor down to the meter using sharkbites with shut off valve shark bite on the line between toilet and meter pipe. Once the house is gutted and remodeled and ready for permanent runs, I remove the temp sharkbite setup and finish off the glued in place cpvc runs,etc. Lovely lovely! I would not trust this tech beyond temporary use..

Thanks for the heads up on the ground. I live in an old rental house, have to replace the main shut off... normally I'd just solder the connections... but it's two stories - I know there's going to be that one drip that will just never stops screwing up the flow of the solder. But it's also my water pipe ground... So I'll just install a jumper across the fittings. For O-rings we used to use either petroleum jelly or windex, ammonia is Basic (opposite of an acid) so it's properties are it's slippery when wet. The windex tip is great for things like slip on rubber tool handles - that won't slip on. Windex makes em slide and when it dries up no more slip.

Matt, I've been a licensed master plumber for 30 years and I agree with everything you said.

Like this guys honesty.

I just replaced an outdoor spigot (silcock) that had a built-in shark-bite connector. Really was a godsend for the job. One point that you might want to make, is that shark-bite connectors will rotate (or spin), so I will definitely have to anchor the tap in the correct orientation.

Used them about 15 years ago and have had no problems!!

I've used tons of them. Never once had a problem with one

These work great and save the day in many situations. I had a leaky main shutoff in my house, and the street shutoff also leaked. That meant I could not sweat any fittings. But with the shark bite, I easily replaced by house shutoff. Then I was free to sweat other joints, any other work with completely dry pipes. I wouldn’t put a sharkbite inside a wall, but in a basement or accessible location they are excellent. A possible failure mode might be long term corrosion of the teeth. So that possibility would keep me from placing it in an inaccessible place. But I am very confident of them over the intermediate term in accessible locations. Another advantage is the ease of installation. Far easier than sweating a joint. And they can be removed with a simple tool (tongs are best).

Excellent video, well filmed, clear and accurate description, you have just saved me having to call a plumber at weekend rates.

I've been in plumbing 33 years and was around when Shark Bites came out. I have yet to see one fail if installed properly. For those that say they will fail if they freeze, I would say who installs a water line where it will freeze? Any pipe can fail if it freezes. I only use them for transitional fittings, like from cpvc to copper, but I do have complete confidence in them. More so than cpvc and pex systems.

I do maintenance work for a living and have used these a lot. I have never had a shark bite brand connector fail as of yet bit I did use a cheap brand from lowes that did fail.

honest opinion. thumbs up. yah ive never seen a failure from one of these but again 20 years... we are not looking at tomorrow guys we are looking at maybe my kids have to fix this type problems. long after im gone. thanks Matt for your insight yes i use sharkbite and will still be using it.

Thank you for a great informative video. I'm stoked that this is the only one I'll have to watch to learn what I wanted about shark bite fittings. Anybody that is going to post a how to or product review should have to watch this before posting their vid. All the information was easy to understand, good camera views, didnt hear anything about what your cat was doing earlier or any other information I didn't want. I rarely post comments and I suppose that is because I rarely see videos worth commenting on. Thanks again. I'll be sure to check out some of your other posts👍

Three things make all the difference. 1. PEX doesn't freeze and burst in vacant rental houses. 2. With the cost of plumbing a new home around $10K for a rough-in with PEX, and $14K for copper, how many builders are going to ask for copper? 3. When homes are built in uninhabited areas, the thieves will steal the copper plumbing within a week of installation.

Great Video Matt. I’m doing a demo job at one of my projects today and we needed to cap one of the water supply lines for baseboard. Shark bites a great for temporary use but I totally agree they’re definitely not a permanent solution that should never be buried in walls.

Very helpful. Wish I'd watched it before I bought them. I installed 4 of them, and 3 of them leaked, most probably due to my error. Because they are in the wall, I'm going back to brass, and will keep the push-to-fits for exposed areas or emergencies. Thanks heaps for this vid - great work. :)

Great info. Thanks for making this video. ENJOY

Very neutral explanation. The learning point is put it in visible place. Thank you.

Thanks for the tip Matt. You'e right, use it outside the wall, especially replacing water heater.

11 years ago I replaced all the copper water lines with pex and used all shark bite connectors and they've been solid zero fails to date ...

I have twelve of these fittings in my basement, that I installed about thirteen years ago. None have failed. Make sure pipe is clean AND deburred AND make sure they are seated ALL the way.

*AWESOME!* The sharkbites are the ONLY fittings that (after two years) haven't leaked ONE DROP. I did a plumbing project where I used various compression/flare fittings on copper tubing (leaked like crazy) - as well as sharkbites - and the sharkbites on pex/copper never leaked at all from the get-go. I was totally skeptical using them for the first time, but not any more!

I've been using them for many years. Shutoff valves, couplings, caps. Much faster and they last. Haven't had a failure in my 13 years of using them. Been testing a 3/4 ball valve version as a main shutoff. It's been thru about 7 summers and winters, only the brass got dull. I trust them

I recently replaced 3 old hose bibs, at least 50 yrs old, the last one finally gave up. but I love the sharkbite system, I put 3 new frostfree sharkbite hose bibs on by myself in about an hour, and plumbed in a whole new sink in a new addition with the pex, its fast, it works, and I have no worries

I have used a similar fitting in New Zealand for about 15 to 20 years. Not shark bite by retaining system almost exactly the same. Have not had any issues with them. Went back to a house that I plumbed 18 years ago to do the plumbing on an addition. Same owners and they told me I was the first andonly plumber to ever work there. She, yes she, did her own very minor R&M. They never had an issue with any water piping.

In the UK they have been around for a long time. I have fittings now that are around 27 years old. Never had a problem once they were fitted (and did not leak)

Thanks for the video and explaining how these fittings actually work (always wondered). Have installed a lot of copper over the years and recently PEX as well. I agree with all your comments about the SharkBite fittings. Really super to have around for quick repairs or temporary workarounds but like you, I would not recommend putting them in a wall or someplace where I couldn't see them. I used these on my water heater about 5 years ago with the intention replacing them with copper but they have not leaked so I've left them in place.

Great video. Great information . Push to connect fittings are great, been using them for years now, with no issues.

You bring up a very intelligent and meaningful point concerning chlorine and rubber. My wife taught microbiology at a major US university for 33 years. One of the things she told me that their labs were constantly changing out were the "squirt" bottle that were filled with chlorine bleach. They stopped working after a while because the chlorine ate the rubber gaskets up. Of course those solutions inside those bottles were a lot higher than the chlorination running through our water pipes but over time I can see your point. Only time will tell. You also make a valid point as to where to use these ( not in walls). Good video. Well presented.

Great point about the gaskets. I plan to install my new hot water heater myself so this is nice info. Use them where you can easily get to them in the future. For a new install with good copper pipe, these should last at least 10 years I bet.

Europe has been using fittings like this for over 40 years with great results. Epdm will typically last a lifetime since this seal never sees any agitation. For an example, I have seen an 80 year old gate valve with a great seal, but as I turned the handle, it immediately started leaking and wouldn’t seal again. Since these are seated and left a lone, you can expect phenomenal results. Most bad stories I have seen, are from installers not installing them corrected.

I've used them under my kitchen cabinet for a ice maker supply line worked out good so far so 👍

i used shark bite and PEX for my air lines in my shop ... 125 / 150 psi .... 4 years and not a leak one ... not even a hiss ... The only failures i have ever had with a sharkbite was because of me .... pipe out of round because i was careless cutting it.

For my two cents: I used them when I redid the plumbing in the pool house. We get snow, so freeze happens. I put a 3/4" on the incoming to a manifold, branched off six 1/2" lines to a low point and installed the SharkBites, one for each the sink, toilet, shower, flowers pots x2, and hose bib. Every fall just pop it off, everything drains, put the manifold in garage, come spring, put a bit of Lube Boss on the o-ring, and put it back together. Five years now, no problems.

I have used the plastic [don't recall brand name] quick fits prior to Shark Bite in exactly the conditions you mention. Both products have never been an issue, 10-15 years of use but I have reservations still of burying them in a wall. Plus, at the cost to value, it is by far cheaper to use copper sweat ons and/or Pex for my purposes. Awesome video and thank you.

I have used a lot of these over the course of 20 years. I have never had one leak, and I've even had them on frozen PEX without a problem. I would call that one a stroke of luck. I have seen them leak when installed poorly - and found the valves to be in perfectly decent condition. I have even replace the seals in these and reused them. I tend to avoid these primarily because of the high cost. When I do use them they are in accessible locations. The most common way that I have used them is to transition from CPVC to PEX. But the usage that sold me on it was once when I had to deal with a defective main valve. The water could not be cut off from the meter face, or at the main cut off inside the home. Naturally, we intended to replace the meter valve, but time was an issue. I was able to cut the main pipe just behind the main valve and slip the new shark bite valve into place. The valve was open in order to do this and I quickly closed it. With the valve closed I believe water pressure would have prevented me from installing it in this fashion. It worked very well and allowed the project to continue on schedule. It took the utility company an additional five weeks before they sent someone out to repair the meter shut off. That 5 weeks would have cost thousands in delays. I would not recommend these in conditions where they are exposed to the elements. The rubber seals are quite susceptible to grit intrusion which will wear them out quickly. And personally, I would never install them in an inaccessible location. I have used them to revamp shower assemblies inside of walls, but only when accessible through a panel.

I’ve used these since they come out on complete installs with NO failures at all

Yeah, definitely keep these from freezing temps... the ice expansion will pull these right off the pipe, especially PEX pipe. Otherwise I love these fittings, very user-friendly even for inexperienced guys like me.

SharkBite is a brand. They sell the puch-to-fit fittings, but also tubing, barbed fittings, cinch rings, and other items. As for the push-to-fit connections, I've used them with various types of tubing (Pex, cpvc, copper, etc) mostly with water, but also with air (120 PSI) for quite a few years and have NEVER had a problems. But, there are always the critics...

It’s hilarious, I watched this video over the weekend, and was interested about your recommendations not to use these where the pipes may freeze, and today I was called in for a water pipe burst. The cause? A shark bite connector installed in an uninsulated crawlspace that had froze and broke its seal. FP. Thanks for doing this review, as it definitely helped narrow down the problem.

I replumbed my entire house using SharkBite fittings 10 years ago! No leaks yet! And I did it in a weekend.

As a plumber that was introduced to these 10 years ago the issue I've come up with the following cons from my own experience 1) The technology/patents have been whored out. What started out strictly as "Sharkbites" has turned into Gator bites, Tec Tites Watts , Blue shark, Cash Acme. All noticeably of lesser quality then the original "Sharkbites" 2) Expansion and contraction, The majority of the property damaged I've seen from Shark bites happen from my old buddy "E&C". As the video shows "Sharkbites" are comprised of 4 dissimilar materials joined together with coefficients that are nowhere near each other. When used in location I would call extreme; near 0c and above 50c these things will literally fly off pipes. 3) They cannot take stress on joints or connections the way that Copper or Pex A can. I usually gets calls for drips or leaks caused by lazy pex offsets or pressure from braided supplies I use them in quick capping situations and areas where I can't safely solder but anymore then that I'll be running type M/L or Pex A I will also say this; they are a great indicator of the quality of work done on the property. If you're viewing a property and you see Shark bites installed in accessible areas were a repair could have been made with more professional/standardized material then assume that there has been the same short cuts and shotty workmanship on the electrical/HVAC/Framing etc

I thought you were very balance with your approach to this subject. I agree pretty much with everything you had to say. I really appreciated when you made it clear that you were giving your opinion and not presenting it as fact. There are too many people out there presenting information as if it were fact when its not and pretending to be experts in the field when they are not. I would be more inclined to listen to you again in the future because of this. Thank you!

I have seen plumbers use them for emergency repairs. I have used them in my house when adding plumbing and moving laundry hook ups. I would not put them in a wall but anywhere inside that is accessible like basement and craw spaces or in utility room areas sure why not. They are great for do it your self work and even pros to make temporary and emergency repairs.

Never had any issues, used on potable water, and hydronic heating. Have some over 10 yrs in service.

i have these connectors on plumbing in my home going on 10 years no with no issue, highly recommended

I love these things for doing renovations I keep multiple in line and caps with me at all times.. For an instant repair of an oops or to cap off lines I have installed them with full water pressure coming out of the pipe ... Yes I got wet but man It was sure nice to have..... However I would never allow one to be buried in a wall or out of instant reach ... Solder it or glue it or pro clamp it ... But for an emergency or temporary stop they are excellent

very detailed mate! love your work, as a builder you are right, i hate calling plumber for disconnections they charge very high for closing off. EXCEPT !!! when you do take them off the plumbers always run off with it

As a plumber, I hate it when builders use these as a temporary cap IF they don't work out what feeds the pipe first. A compression cap I can slacken off and if it still has pressure, I can tighten it again. A push-fit is all or nothing and when the builder has forgotten which pipe is which, I can easily waste an hour. Moral of the story is always label a capped pipe.

These types of fittings have been used in industrial applications for years before being available for residential use.

Shark bites are not my first option ever but definitely a great temporary repair option. They have saved me on solder jobs where the city meter does not turn off all the way and can allow me to put a valve on a home

I've used these for both copper and Pex for my household repairs/modifications for 20 years. I wouldn't use anything else. Have never had a leak, under sinks, and for the shower hot and cold pipes in my current house.

I just had shark bites installed in 3 locations of my home in 2018. So far so good I will update if anything crappy happens

I use them all the time and I've never had a problem with them whatsoever. I absolutely love these things. I highly recommend them.
