Product review (4 stars): Works Well!!
We really like the convenience of this circulator. Our water heater is on the far end of the house, so we would have to send a gallon or so of water down the drain before getting hot water.  It works well, 2 weeks so far. I wish we would have installed it sooner. The pump is also very quiet, no vibration.

The only reasons I am giving 4 stars instead of 5 is the price. At $400 +  it does seem very expensive. Also the button used to activate it is gold trim, when most kitchens now are stainless steel so a little clash in color.

I payed a professional to install it, he did the job in less than an hour. We had to shut off the water to the house. I also called the help line with some questions, the tech at the other end was very knowledgeable and answered all my questions satisfactorily.

The pump appears well made and I hope it lasts ten years!
