How To Install a Pool Pump - Plumbing the Pump, Part 2 of 2 

God love you for this. I don’t have a handy man around to do work like this around my home but I am able to take care of most things with very clear and directive videos like this one. Thank you for sharing your knowledge so I can save some money and do the work myself. It looks good and is a quality repair thanks to your instruction and I must say it feels good too knowing I could do it myself.

Most every pump installation manual calls fora minimum of 10” straight pipe on inlet side to minimize turbulent flow and cavitation. Pump will run with less strain and cooler temp thereby extending its life

Why wouldn't you just use a high temp union on the suction and discharge of the pump?

What made this a great instal is that it had to be done on such an old system, real world installation. One piece of advise, if the motor is stressing that union just shim it to relieve and pull the weight of the motor is putting on the piping. Great job considering what he had to work with.

I wanted to thank you for a great video. I'm almost 70 and just installed / replaced my old 1 hp challenger. The union process you showed me saved my rear end!! I did the coupler on the front of the pump and the union on top. Worked perfectly, no leaks. Thanks again! Much appreciated!!!

If everything is glued how do you remove pump in the fall to bring the pump indoors. I had my pump piped in last yr. no leaks. This yr. I put it back together and leaks at the unions. What do I need to stop the leak?

Its actually off the ground, you'll need to shimmy something under pump or it will leak in the future

Hi David, two questions today. Is it possible for my Inteliflo 3hp VS pump to transition smoothly from one speed to another or does there have to be a one minute gap, 1900-2700 for example. The second question is, is it possibly to remove phosphates easily. With the poolrx I wasn’t too concerned about them but I think even the poolrx is reaching its limit. 1300 phosphates as always thanks for all you do.

How To Install a Pool Pump: Ever wonder how to attach two pipes that seem impossible to connect? Here I show you how to install a pool pump properly and easily.

Hello. Thanks for your videos! I disagree with the below post that "you are using too much glue". Nothing like cutting back on the glue and fitting it all up, only to discover a drip or leak and have to start all over again! I have two in-gound pools in two homes and your videos are extremely helpful, even though I am an Engineer. Questions: I am installing a new Pentair Multi Speed and feel I should install a check valve in line while the system is down and all tools are available. I believe I have two issues, which may require two check valves. (1.) Should there be a check valve on the pipe the pump suction prior to the pump to prevent water from retreating to the pool, now causing the pump to take 30-60 seconds to prime on each start up? (2.) Should there be a check valve on the pipe prior to entering the Pentair tablet chlorinator to perevent high chlorine content H20 from backing up into the equipment? (3.) Unrelated to the above, I installed a Pentair Chlorinator 320 and found that the tablets are not being consumed, causing me to manually add chlorine to the pool. My theory is that the supply line PSI feeding the 320 is very close to the PSI of the pipe the chlorine should be exiting to, thus causing it to remain static. I added a tablet, filled container with water then capped it and tablet remains whole after 2 days. Any suggestions? (4). Lastly, this same pool has a raised spa with a waterfall into the pool. When the pump shuts down, several hours later the spa water seeks the level of the pool. Would a check valve above #2 remedy this issue? Thanks for any assistance you may offer. Jack C

I am redoing my pump because of an air leak and this video is what I needed. Thank you

Dude, great video. Very helpful. I appreciate your narration of what you were doing step by step. Really nice work!

I wonder how you will disassemble this pump when it fails. It would be better if you put an easy-to-disassemble record on the suction side.

Minta tolong.. di ter jemahkan ke bahasa Indonesia.. terimakasih..

Why put only one union on the discharge? Couldn't you put another one on the suction? Would be easier to remove the pump if needed repairs? Just curious...

That final connection is always the worst. No slack whatsoever to make up for measurement/cutting errors or, worse, failure to fully seat the pipe into the socket.

“Fitting Extender” Goes Over Outside Of 1-1/2” Elbow? #LearnSomethingEveryday #GotFittingExtender?

Looks like a lot of cavitation in that pump...seems like air is getting sucked in the pump on the suction side

That inlet is way to short.. whoever originally plumbed that didn't know what they' were doing

Wouldn’t it be better to union both ends for easier removal for winter.

I can guarantee the length of that straight horizontal pipe going into the pump is not to spec.

Where do you get your 1.5 and 2" extender fittings? I have looked at all big box stores and found nothing. Is there a proper name for the fitting where I can look it up online? Thanks

thanks for this video. in the future if you want to reinstall another pump, how do you do that at the front now that you dont have any length of pipe left?

Thank you!

I would have re configured to use a union at the inlet as well. Pain in the A they way you did it if you need to ever service the pump.

I have a question, my pump is not sucking up the water and rotating, the dial is at zero, could it be because there is leaking on the pvc pipes? I am a lady, I was watching your video, I don't think I can do this. How much would a pool guy resonalbly charge me for putting new pvc or fixing the leaks? The motor and pump are still working, just leaking at the connections.

I have a old 1 speed 3 hp 1996 challenger and the motor need replacement . Is it wise to buy a 2 speed motor to replace the one speed motor for energy saving when I just want to circulate my chemicals in the water???? BTW. I have an 8 jet spa and when valved off the spa has one separate jet that acts as a pool a overflow water fall while the pool is in valved for circulation and skimming. I also have a return separately valved for my polaris pressure side cleaner that i run as needed . In this 15000 gallon pool with a 10 person spa.

I have a 40-50k pool that has three return lines I had to plug one return line. Will that disrupt anything or cause low suction?

Wouldn’t it be easier to just replace the whole pipe from the pump outlet to filter with a union to the filter?

Good day! What size of pipe is ideal for pool equipments such as motor pump and filter? Is 1.5 pipe okay? Thank you very much.

OK I'm going to pump it in right away, I have to pipes coming out the ground ,I guess the one on the left side is the skimmer and the one on the right is the bottom drain .

do you HAVE to use schedule 80 pipe on the discharge side?

Theres plenty of ways without using unions but everyone has their own style.

Where do you get your Pool tite glue from? I cant find it anywhere in the Martinsburg WV or Winchester VA areas... I checked pool supply stores and plumbing supplies. Thanks for the video.

Great video! Can you run 2 Pentair Variable Speed Pump? Filter and water fall feature? If yes, where do you connect the green and yellow cable to the Aqua logic? Theres only 1 slot for green and yellow cables for 2 green and 2 yellow cables.

Could you use a union on both suction and discharge side so next pump replacement your not having to cut out pipe, if ever need to remove for service? I never see union on both sides? I’m very new looking at doing my first pump, filter install and not sure if I’m missing something as to why not to.

why not use a union on both sides??

What happens when you have drips on the male adapter in front of the pump you just glued together with no union? Glue those male adapters into the pump

Are you using regular schedule 40? Also if my pump is 1 1/2 HP can I use schedule 40 under ground. I'm repiping the pool I'm unsure of what type of pipe would be best and. I'm worried about using 90's because of flow restrictions. I would use 45's but I don't want a lot of joints under ground. I could use a sweep as well but I want to really manage the flow. Right now there is black poly pipe with hose clamps keeping it together.

Just wondering...why SCH80 pipe? How how hot does it get over there?

Is there any cement to replace weld-on 746? Want to install an inline chlorine dispenser but don't know which cement to use in homedepot or lowes. Is Oatey Heavy Duty Gray PVC Cement OK?

If you are swapping the same pump for the same model again would I need to do any additional plumbing works, asking as an electrician

It's ok to not use Teflon!?😳

I had a couple of questions on that joint stick ... I recently tried to plumb my above ground pool filter between my new pump and old cartridge filter. Right at the spot where the threaded pipe screws into the the outlet is where my leak is ... I used teflon tape on the threads ... is that joint lock stuff better than teflon tape? Does it glue the fitting in? Should I be using an 0-ring? Thanks for any help. Jeff

Should you sink your threaded pipe fittings all the way? I did not and have a vac. leak that won't allow a prime. I don't see water or air coming from the threaded areas and did use teflon tape. Day 4 of the challenge! I may have to do corrective surgery.

Can you use the unions for both connectors to help avoid the worry of the one shot and the last glue up going slightly wrong?

Thanks for the video. Do you have to leave 24 hours as glue seems to set pretty fast? Stay Safe!

What would you do if you did come back to leaks? Would you have to start over?

is it not necessary to fasten the pump to anchors such as Kwik Bolts ? You have the pump just sitting there .

0:07 is it necessary to use the *POOLTITE* glue or can I use regular PVC pipe glue and primer? Pooltite is used for underwater conditions but if it is a new installation, why do you have to use it?

Do we have to wait 24 hours before turning on the newly installed pump? Thanks for the wonderful video!

Can you use regular pvc from lowe's? Pool and jacuzzi.

Great work

Nice Job. /John

No experience in plumbing work but work

Do you know how much conditioner I should use for a 45000 gal pool?

I appreciate your attention to detail in this video. Easy to follow and understand also.

lol waaaaay too much glue

Long time lurker and big fan.. Your videos and reviews are awesome. So much valuable information.. I noticed you film with one hand and demonstrate with the other. Invest in a Go Pro Hero 3 with the head mount so you can use both your hands I strongly recommend .. also on your plumbing video.. I'm not sure if your familiar with the Praher 2" High temp Unions . They thread onto the pump housing and make removing the pump so much easier for future repairs. Also the weld on 740 Pool Regular Clear glue works great no primer needed .. Keep the videos coming! Thank you !!

Great video. I have to install the same pump with the same setup EXCEPT that the suction side at the valve has only a sliver of pvc pipe which would not allow the same connection as in the video. Any suggestions would be much appreciated.

They have - 2" or 1/2" MALEXSOC HI-TEMP UNIONS that are already assembled for you, and all you have to do is plumb your pipe right in.They should have them at your local poolcorp distribution just to let you know 🙏🏽🌊

what is that white stuff on the thread....just good old silicon ?

That final step is always anxiety filled.

i see a leak behind the pipe your cutting at 1:57.

Seems like an awfull lot of flow restriction. Two bends following each other directly, no length of pipe in front of intake, union following directly after a double corner ....

how did you remove the old pump from the cement? We have something holding it in tight and don't know how to get the pump out

I was surprised not to see the pump being bolted to some concrete. Is it OK just to let the pump sit on a surface unattached? Thanks!

Anything special about that union? Certain type?

Very nice teacher,I wanna try too

Awesome video. Thank you for making it. I have a few questions, and any suggestions would be appreciated. I'm disabled. I'm trying to do this via wheelchair, and am determined to do this myself, lol the swim season may be over by the time it gets done, but hopefully it will get done, and done somewhat correctly. I've just now starting my hard plumb using Sch 40 PVC on my above ground pool. I'm planning to run the lines from the skimmer/return to ground level for added support, and to, hopefully, increase the distance a little further between the pool and the pump. (I actually dry ran it originally with it just coming down from the skimmer, a short piece of PVC, the Ball Valve-cut off, another small piece of PVC, a 90 placed across from the pump, a short piece of PVC, the Union, a small piece of PVC, and the threaded/slip connector into the pump, but by the time everything was added in it just looked way too heavy to just be hanging there in the air, and having no support, so I decided to start over, and run it all the way to the ground, across, back up, and into the pump). I've done a little on it already, but with my physical limitations I'm only able to handle doing a little bit each day, plus with all the rain, rain, and lol more *&%$ rain, I've not gotten much done. (So far I've only put in the new thread/slip connection in the bottom of the skimmer, added a short piece of PVC, put in the 1st Slip Ball Valve below that, ran the PVC line to the ground, and put a 90 at ground level to start going across with). Here's a lot of my problem. I have very limited space between the pool and the pump, they are currently approximately only about 3 foot away from each other, (but I do plan to leave enough pipe available in the line to cut it and bury it next season, and move the pump to a different location about 5-6 more feet away from the pool. (The pump has been in this same location for about 5 years now while using just the regular hoses, and has done fine, I'm hoping the hard plumbing doesn't cause it to have flow issues by being so close.) Do you think this will cause a flow issue in regards to the PVC pipe, and the close location to each other? I'm placing Ball Valve-cut offs on the skimmer and return sides, and will also be T-ing a line off the return to make a DIY fountain with its own cut off. I also have Unions that I'll be using for easy disconnect. Where in the line should that Union be placed? Should it be closer to the pump, closer to the skimmer/return, or does it really matter? Do they do better if placed up and down, instead of laying across the ground part? Do Unions require any type of Teflon tape or sealer, or are they self sealing? At the pump, and at the return a threaded 90 would work better there and take up less space from having to add another connector in. Is there any issues with using a threaded 90 in those areas, or should a straight connector be used to prevent any additional possible pump flow issues, and then the 90 glued in after that? Also is it better to use (2)45s instead of a single 90? Also the clear line on the pump that has the metal in it (I think it's spa tubing possibly or something like that but I'm not sure). Is it alright to replace that clear tube with PVC as well or should the flexible clear tubing be left alone when hard plumbing the system? Ok Last question, lol I bet you're thinking thank goodness, it's about time lol: What type of white paint was used in the video to paint the pipe with, was it just regular white spray paint, or is there one specific for PVC pipe? LOL after just gluing together a couple of parts so far I can already tell it is definitely going to be needed? Sorry this ended up being so long. Thank you for any suggestions you can offer. Have a wonderful Night!!!

Hey thanks for the tips - I followed your guide and it worked perfectly! Thanks again.

More glue the merrier

What do you do with old pumps?

Is it OK to us the yellow cement glue its suppose to be for all wheat her ? Its a one step process or should I go buy the blue glue.

yes. good Job. You made it easy on me.Thank you

Great job good to see someone take pride in their work.

Hey, great videos as usual! Been watching you for years. I am removing a Heater(won't be replaced) installing a new MultiValve and new DE Filter on my pool. There is one check valve in place. It is between the heater outlet and the return. No check valve between the pump inlet and the pool. Do I need a Check Valve? If so where? I also see a few places where there are elevated loops to prevent siphoning I guess. One is between the Pump outlet and the multivalve. The other is between the heater outlet and the return. That is also where the check valve was. Do I need to redo that heater outlet one when I remove the heater?

hello allfrends

Hahahaha you almost didn’t get the suction side in fast enough 😂😂 that’s was epic I said there you go the same time you did 😂

which is the inlet and which is the outlet? I have similar pump and want to connect to my pool? Cheers in advance and good video:)

Good job, Mr.D. I think a tripod was mandatory for this clip. Where do you get your PVC white spray paint? I never see that at any of my distributors...big box hardware store? -TM

Thanks for this instruction. I am in need of that pvc pipe extender to fit over the outside of a 2" elbow. Can't seem to find one like that. Do you have a link or part number?

I love the spray paint! Good as new!! What do you do when the client is standing by watching the process?

Purple primer! Yikes.

Very good 👍 brother, I have one like it, and I need you to give me some advices to install it, please contact me
