I had no idea this unit had a timer until I had a handyman tell me, and turn it around, so I could see it, which the guy did not do that installed it.

Does this circulator cause any problem for the pipes when there is no return line?

it’s a shame he did it wrong. arrow needs to be point towards the water heater. you can tie it onto the cold side but it’s best to tie it into the boiler drain so it’s not exposed to really cold water but that’s where the check valve comes in play as well. but you want to still tie it into the boiler with a check valve and the arrow has to point towards the tank in order for it to recirculate. if it’s away then it’s just a booster

Thanks for such good instructions

Where is part 2?

It would be nice to get a how to video from someone who actually understands how it works. You just hook up this magic valve thing in the bathroom and it works.:(

There is no reason to drain the entire tank. As has already been stated, you simply need to relieve pressure from the system so that the water doesn’t come out of the top of the heater when you remove the hot water line. Lastly, your water lines, particularly the supply line is in horrible shape. It’s obviously been twisted around and linked. I recommend replacing both lines.

Do you use the heat trap installed in the anode rod with this recirculating pump or does it have it have to be removed first?

Did you have a heat trap installed in the anode rod, I couldn't tell? I'm doing the same install but not sure if I should install the new heat trap I purchased? The old anode rod did have a heat trap installed. I purchased a new anode rod and a new heat trap but I'm not sure if it will work with the recirculating pump or not? Your thoughts please. Thank you!

After installation of the Watts Hot Water Recirculating Pump,I started using it right away. As long as the pump is running all is fine, but when the pump shuts off I have pipe bumping at the faucet where the bypass valve is installed, when running water in the kitchen. I installed an arrester on the Hot water side at the by pass valve, and still have bumping when running water at the kitchen with the pump off, I turn on the pump and it stops. Should it take an arrester on the cold water too, to stop the bumping?

I wish the timer was in 3-4 minute intervals instead of 15 minute intervals. I don't need hot water flowing back into my cold-water side. Does anyone know of a time like that?

This is all wrong. Just putting a pump in your hot water line will do nothing except burn up your pump since there's no where for the water to go. You need a return to cold to actually recirculate. And it's a gas heater. It's pointless to shut off power. And you don't need to drain the tank. You just need to relieve pressure by turning off supply and open a hot water tap in the house.

We did this with this unit..... the cold water spigot in the sink works just fine after a few seconds it gets cold as usual....the problem we have is the shower in our master bath. The cold line is "always" scalding and never gets cold....even when we turn the hot water spigot completely off the cold always stays scalding..... what gives?

The sensor valve looks like it's pointless.

My gas bill was 600 dollars till I shut the gas off and now I use propane from a bbq pit regulator cali propane is 16 dollars a mouth I live alone

I have found a much better option than using the built-in analog timer on this unit. Set it so the pump is on all the time, but control the pump through a Lutron Casetta outdoor plug. This unit was designed and intended for outdoor lighting like Christmas lights, but it will also control, small appliances and small motors, and this qualifies. We are heavily invested in Lutron lighting switches throughout our house for a variety of applications. This allows total control through an app. It takes into account daylight savings time changes. And if I want to go out of town for one or more days, I can turn the pump completely off. Likewise, if I needed to run the pump at an off schedule time, I can simply open up the app and turn the pump on as desired. Total scheduling is available through the Lutron app. And as I said, it adjust for daylight savings time. This completely eliminates the need for an analog timer that you have to go reset if there’s a power outage.

I recently replaced the pump with a new one. The question I have is how to connect to an under sink water filter? I m not sure of the correct piping for it. The sensor valve seems to be working correctly as the inlets for Hot and Cold to the sensor valve are piped per the instructions to the sensor inlets. However for the cold outlet side with a standard water filter cartridge housing water filter how should it be connected? Any help is greatly appreciated.

For many people (those with water heater in basement) -- by far the best system for hot water recirculation is a gravity type system. Always hot water in hot water side, always cold water in cold water side. No pump required. No worrying about setting timer. No hot water in the cold water line when pump is running.

Really ????? Both your hot and cold heater hoses are kinked. Count on it failing and leaking in no-time.

What if you have two sinks do you need 2 of the units that you install under the sink?

Talking to much

i have a question- I have set timer to correct time and using pins for 'on ' times what do i put timer on? On? or Timer? I dont understand the difference between the 2? I am using the pins for the timer so should it be set to timer? I only want it heating in morning's and evenings for shower times

Dude!....Volume too low!!

I found this video last year and I had just had the circulation pump installed for winter (to avoid freezing pipes in the basement - Colorado). I set the timer from 10 PM to 7 AM for the winter and despite some very cold, freezing and below freezing temps, it worked great. No issues. (We were out of the country for the whole winter.) For this year I just reset it from 11 PM to 6 AM - just to save a little bit on energy costs - as I am not sure how much extra energy it uses. Thanks for doing this (yes, it was 6 years ago - but it has been excellent help to me).

How is this a circulating pump when it is only on the HOT side? I would NOT use this video to do my project. The is no breaker for a gas water tank.cold water line should be addressed as well. Hmmm…

If you are circulating hot water through the pipes you need a return line from each faucet or how does it circulate in a closed system???..

That is acting as a booster pump, not a recirculation pump

Very clear!

FYI the water heater isn't listed on your electric panel because it doesn't take electricity, it's a gas heater, also you don't need to drain the heater, just release the pressure.

This was an exact replacement for the old one that lasted about 10 years. ru-vid.comUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).

If your hot water is 40 feet away it's still going to take as long as it did before to get to the shower head or sink.

Great video. Makes sense. Problem is the creator of the video does not repy to ?s

I have two water tanks set up in Parallel - where do I install this circulator?

That was all sorts of wrong. Wow

I'm sorry, but I can't take instruction from someone that see's no problem with massively kinked supply lines.

You should really consider replacing your cold water inlet line with a flex hose.

Hard to believe I'm the first commenter...I'm new to all this re-cir pump stuff but after buying and refurb/remodeling my mobile home and final resting place I decided to try this system for my kitchen sink...which is way on the other end of my place. So I found one of these units on Ebay and installed it. For me the install was a piece of cake, but I'm very mechanically inclined. I only needed one medium crescent wrench... Done! Beware...the two main fittings in and out of the pump use a "ONE" way valve. Once installed I had questions so I contacted the tech service hot line provided with the literature. I was amazed at how quite this unit is...as the tech guy said... these pumps are quiet and some are very quiet. My other concern was that the motor/cartridge housing get fairly hot. The Tech guy confirmed that yes it does...when the pump is operating. After 24hrs this has been confirmed. OKAY...now here's the rub. Instant "HOT" water? Not gonna happen. Hot water within a minute is acceptable. Now for the rub...The way this works is that it keeps the hot water circulating thru your water system...hot side to cold side constantly, or should I say warm side when not in use. The pump thermo sensor controls this. BUT...on the flip side...if you want "COLD" water it take as much or more time for that to happen...hence the rub or trade off. So for me...instead of waiting "Literally" 2 minutes for warm to hot water...I get "warm" water pretty much at the hit, and the hot within a minute...which is much better than my original system. So... okay...it does a pretty good job. Now the final test will just be time & reliability. I did a LOT of research and shopping around...and some of these pumps are ridiculously expensive! This original post was from an Eastman Nevercold 70601 under sink unit video. I do a lot of business with Amazon and the Eastman water heater top mount unit on Amazon is under $300 bucks. But essentially the same unit under sink mount is over $500 bucks! I don't get that. If anything it should be the same or less and they would sell a ton of these under sink units. They are really easy to install. So there's my take...worth a couple hundred bucks...and I'm reasonably satisfied...and that's no easy task.

When the valve closes, isn't the pump then pumping against a closed system? Is that not bad for the pump?

Your video didn't show anything don't quit your day job, you shouldn't do how to videos.

Watts is the best!!!

Ok why did he need to turn off power if he has a gas fired water heater? 🤔 Also why is he draining the tank if the pump is going to be installed in the water line at the top of the heater?🤔

AFTER watching your video several times, it finally clicked. What was confusing was the clock hands. It would've been helpful if in your video, you explained the clock hands are not for reflecting the time, the time is those teeny tiny numbers. Just my bone-head-two-cents.

Read my Instruction booklet then watched your video and STILL I'm dumbfounded ad yo how to set the time so the unit can dispense the jot water at the correct times. For " bone- heads" like me, your video doesn't clearly explain that step. Help?????

My upstairs shower will be the last item in the run. It is fed via the run from the kitchen downstairs.

Did he say hot water heater 🤦🏼‍♂️

He turned off the power and his water heater is gas 😂😂😂

Looks like you might have to disassemble bc you put together outside the sink drain! Good for the demo and something you might not think of in advance...oh I have to work behind the plumbing to wall mount!

Brilliant! I was completely mystified by this thing and have been putting off trying to set it correctly for MONTHS!! This video is so clear!! I finally understand! Now Ima go try it.

Can the valve be serviced? I'm filtering well water to 5 microns and I'm getting less than a year before the valve fails and circulates hot to the cold side.
