Rated 4.0 out of 5.0 by Hedonist Second Try
Second one I bought, first died after 2 1/2 yrs. Family member has one that has lasted many years. Appreciate having hot water at faucet so decided to give it another chance. When it works, it works great. Hired installation which was very pricey.
First tried changing the sensor, a diy job but that was not the problem. Considering cost of sensor replacement, new pump, and installation, the new "$200" pump cost over $500.

Rated 5.0 out of 5.0 by MG Works as expected
Pump was well packed. Seems well made. Installing pump on top of water heater was easy.
Installing valve under the sink was a bit harder due to difficulty of working under sink. However
the hoses fit well and did not leak at all. Pump only uses 25 watts, I run it 16 hours per day.
Cost for electricity for pump works out to be about $1.50 per month, not bad. You do get warm water on the cold side of your faucet where the special valve is installed. However, that does not happen
at other sinks in the house. In my case, with the valve installed at the sink most distant from the water heater, it was a big help to the two bathrooms along the way.
The only change in the pump I would recommend is the plastic cover on the timer tends to fall off
easily, it needs a more positive way to attach.

Rated 4.0 out of 5.0 by Randy Warmish water on demand
Before installing the pump I had to run 2 to 3 gallons of cold water down my masterbath drain, waiting on warm water. Now I set the pump timer for my usual wakeup and bedtimes and warm water is available immediately. The water is not real hot but is warm enough for hand and face. I estimate I save over 100 gallons of water per month now.

Rated 5.0 out of 5.0 by DoctorDetroit Why wait? The fastest way to a hot shower.
I heard about recirculating hot water systems years ago and assumed it was a "luxury" item that would cost thousands to upgrade my current plumbing. So, for the past 10 years, I lived with the fact that it took a long time for my shower to warm up. I would turn on my shower and then go do some other task, like make breakfast, cut the lawn, or watch a movie... and then, by the time I got back, it was nice and warm.
Waiting for the water to warm up seemed like an eternity, like waiting for water to boil, or watching paint dry.
Before installing this product, I timed how long it took for my shower to warm up. It took about a minute and 9 seconds. (I always assumed it was more like 5 minutes). After completing the installation, it only takes about 20 seconds... about the time it takes to disrobe. Not too bad.
Highly recommend, not only for convenience and water savings, but to start each day without disdain.

Rated 1.0 out of 5.0 by Beavertail Don't need the pump. Valve alone works. Save $$$.
I had installed this pump and valve a month ago. Put a thermal couple on the hot water copper pipe to monitor the temperature. As I was testing the system, I discovered, with the pump completely OFF, natural convection when the valve is open upstairs, will cause the water to recirculate naturally! It works by itself without the pump running on the hot water tank.
The pump is actually quite useless as it doesn't seem to push up the temperature quickly. Sometimes it even pushes the temperature down. I am wondering if the pump was pumping backward. I figure I had a faulty pump. Exchanged one and yet to test the new one out.
The bottom line is, this valve is a great product. Save yourself some money, don't buy the pump/valve combination, just the valve. You will get hot water (95F) naturally without any electricity cost!!!

Rated 4.0 out of 5.0 by Dallas Solves a big problem
Our master bath is a long way from our hot water heater, and we'd have to run the shower for up to 5 minutes to get it up to temperature. When you install this pump, it forces the hot water to recirculate to the tap on a schedule you choose, so you have instant hot water. It works great, definitely as advertised, and very easy to install. The downside is that when the pump is running, it's really running, forcing the hot water heater to run more and this will drive up the gas bill. The trick is to schedule the windows when you want it to run as tightly as you can, but then expect to have to run the water more in the other times of day in order to get it hot. But at $200, it mostly solves a problem that we thought could only be solved with a $2000 tankless water heater. If you need hot water on demand at unpredictable times, it may be worth buying the tankless heater. A pump like this was recommended by "This Old House" as an alternative to the tankless heater.

Rated 5.0 out of 5.0 by Tom This is a terrific product. Seems to work precisely as described.
This product seems to work exactly as described. You will want to make sure that you have everything on hand that you need to install the pump quickly and get the hot water back on line.
