Questions & Answers

Asked by Bobo May 9, 2021

Hello, The answer to your question is yes. All you are doing is just reducing the pipe size that has nothing to do with the recirculating pumps function. Hope this helps and good luck.

Can I bypass the timer? I intend to install a motion sensor in the bathroom, so when the sensor d...

Asked by Dennis March 22, 2021

Hello, If you don’t want to use the timer just keep the lockout tabs for setting the timer in place. This allows you to setup your motion sensor, however bypassing the timer will not guarantee you will have hot water as soon as motion is detected. Just so you know. Hope this helps.

Does this pump have a built in check valve

Hello Sonny, No the pump does not but the sensor valve does have a check valve built in.

Timer loses 15 minutes a day. Is there a fix for this?

Asked by Ned February 9, 2021

warranty replacement or just set to 'on' to use 24hrs vs. timer; one of these i installed, the timer switched died even though

Will this work with a Rheem PROE50 M2 RH95 water heater that has heat traps?

Asked by Gene February 9, 2021

I have heat traps in my both my supply and outlet lines and the pump has been working great for years. I love that when I turn on the hot water valve I get hot water within seconds instead of minutes.

How many G.P.M. does it pump?

Asked by Redrocker February 8, 2021

Not sure but we get a good flow with faucet open full.

Is there a check valve in the thermoststic valve?

Asked by Dom January 31, 2021

No it will not. Not having the pump run leaves your water system exactly the same as if there was no pump installed. You are not afraid of cold water going to the hot faucet then, so exactly the same situation with the pump installed but not running. No issues. On the contrary, with the recirculating system, when you turn off the hot water faucet, you will still get some hot water at your cold faucet side. This is the effect of using the temperature controlled valve. The hot water remains will pass in a few seconds. No concern for normal use. But if you absolutely do not want any hot water from your cold faucet, then you should consider not using this recirculating system.

great pump
works as intended and i should have done that years ago, will be great if your expectations are realistic, it gives you hot water within 3 seconds you can use now, its not boiling hot as it is design to keep that water in your pipe to 95 F, the water in your tank is set at 140 F from the factory...had to buy a few screw on pipe fittings to install it to my tank because the contractor who originally installed the water tank soldered everything, not the fault of the product in any way
Love the comfort of warm water in few sec!
Love the comfort of using warm water in few seconds. I should have installed this long time ago. Saves a lot of water while waiting for hot water to come. Extra electricity costs but in the cold winter days, the heat losses will just be extra heat in the house. I tried using timer but when you use the shower when the pump is off, the hot water is mixed up and is not consistent. Looks like the cold water goes through the hot water line via sensor valve. Needed to install check valve to avoid this. I kept it running all the time.

A heavy duty recirculating pump very easy to install. The built in timer is a big plus. Hot water within 6seconds, it use to take one minute.
by Mike
Great product solved a problem.
We have a run of about 80 ft. to get from our water heater to our unsuite sink and shower. We now just turn on either tap and have hot water in mere seconds instead of 2 minutes. Amazing and easy to install with just watching a video.

I am glad that I bought this pump and had it installed. It gives hot water faster to the furtherest point in the kitchen faucet. The only thing it seems like the cold water is s little slower. The built in timer makes so you can set it for when you don't need it. I have only had it about 6 weeks. It should save water and energy over time.

I can't believe the solution to a long-annoying problem was so simple!
I had always been under the impression you need your home to be specially plumbed to allow for recirculating hot water. Surprise! I was getting ready to replace a 9-year-old 40 gallon water heater and was contemplating going tankless. Our biggest complaint with our current plumbing is that it takes FOREVER to get hot water in the kitchen and I hate wasting water waiting for it to get hot. I realized a tankless system wouldn't solve this problem and somehow stumbled onto this product during my research. Our water heater is in a dedicated indoor closet so a tankless system wouldn't necessarily save us any space. I bought the least expensive Rheem 40-gallon water heater and the Watts pump. Together they cost less than a tankless system and installation took just minutes. It's brilliant! The only *small* downside is that if you want to get a cool glass of water from the kitchen or bathroom faucet, it takes a moment to flush out the hot water. No big deal.

I bought product as new and was lazy to go local store, so I ordered it delivered to my home. There was no mail box for it,just the original box with a mail sticker. Just a few pieces of paper as padding to handle rough shipment. Fortunately it is not damaged, but upon careful inspection I believe it was a customer return, the timer had been set. I got everything ready to go, so I installed it anyway. It works as expected, there is a little humming when the pump is running. It is obviously louder than a Taco 007 bump on my boiler, on which I need to feel slight the vibration to confirm it is running and no audible sound. But the setup is in basement, so it is still OK. I am not sure the reason why the previous buyer returned it and it is still OK to buy a returned product. But at least it should be labeled as OPEN BOX, or refurbished, Not as new.
