    • Works fantastic
Easy to install and works fantastic! Very happy with the purchase

    • So far, great!
I just installed the Wasserman. IT WORKS GREAT! It took about 15 minutes to install the pump on top of the water heater. The sensor under the sink took about 40 minutes just because you have to think through how to mount the sensor. It would have been nice if it had come with a mounting bracket. In the end, I didn't mount it. It is just kinda hanging there. I particularlly like the temperature adjustability of the sensor compared to sensors without that feature. I get hot water within a few seconds compared to a few minutes. It is rated at 36 watts so I'm leaving it on 24/7 for now. So far, so good! ... show more

    • Good pump; poor timer; committed seller support
Set up is simple, easy, and takes about 45 minutes. Pump works very quietly. Timer does not work; this is a problem noted by other buyers. You will need an outlet timer, or you can run the pump continuously. Manufacturer unable to solve the problem, but did provide timely and helpful suggestions. The pump and accompanying by-pass valve is so superior to other pumps on the market; you don't buy this for the timer, it's the pump that counts. I have solved the timer issue with a $6 outlet timer (just leave the switch on the pump in the "ON" position. Works better than expected ... show more

    • Wasserman Hot Water Recycling Pump
I recently bought an older home where it was difficult to get hot water without running the water for a long time. The solution was installing a recirculation pump. I now have hot water on demand! This pump is on a timer, so that allows hot water to be delivered only during times when i need it the most. An excellent purchase that also saves water and money. ... show more

    • FINALLY, ONE THAT WORKS AS DESCRIBED.
This works great. Does exactly what it is suppose to do. I've tried other models and brands and they were all worthless.

    • Works as advertised
I seldom write reviews but this system seems to be the real deal. Just installed today, easy install, quite and seems to work great. Went from couple minutes waiting hot water to maybe 10 seconds.

    • Connection not to be trusted.
Review Image by Nate B. Nate B.
The temp control that goes under the sink is well built. That is the reason I selected this kit. The issue is the pump inlet connection. It is it retained by only a small wire. It is less secure than a garden hose. When snugging mine up to stop a drip the connection separated creating a hot water geyser. Bottom line the connection cannot be trusted. I am going to look for a pump with a more secure connections even if it is harder to install. ... show more

    • Water heater snap ring fitting on the pump is poor design
Review Image by Wade Wade
Why did you pick this product vs others?: First the plus - the bypass valve is great. Very solid. Well designed. Leakage: The pump design is lousy. The fitting for the water heater attaches with a snap ring. The fitting popped off when I turned the supply line water on after installation. Water went everywhere and the snap ring got wedged in the fitting. I bought a second one thinking maybe I tried to tighten it too much, but the fitting on the second one popped off as well, before I could even complete the install. I was able to snap it back on, but I absolutely do not trust it. It's a poor design. If you install this, you're risking flooding your house. I don't think there is any way to make this work. Additional Info: I reached out to Wasserman at their web site and they were very responsive regarding this issue. They are working on an updated design to fix the problem. I'm bumping up the stars due to the customer service from Wasserman, but I still believe the pump still isn't usable in it's current design iteration. I'm looking forward to seeing the updated design because overall, this was a good value and otherwise well-made if they can get the fitting design revised. ... show more
