Cold water is tepid at start, but quickly becomes cold.
4 stars because the valve is plastic - if it were metal, would be 5.
I've used these for probably the last eight years. I'm on my second pump at this time. For people who do not understand the function of this valve, it is simple. When water on the hot side of the valve cools, a bimetal valve in the product opens up and lets the pump (at the water heater) pump the cooled hot water over to the cold side and back into the water heater. When the hot water at the valve hits somewhere around 100 degrees, the valve closes until the hot water cools again.
I replace mine about every two years. I consider it a tradeoff: $25/year for instant hot water throughout the house. I just don't like the current state of Grundfos quality control. Going to try the Watts version of this this time. Same product, but it should be a different batch.
However knowing a little physics I reasoned that at our house where the water heater is in the basement and the bathroom on the second floor it takes a minute to get hot. I figured hot water rises and I might not need a pump. I was right. It works perfectly with natural circulation.
I purchased one of these and installed it and all the hot water above the water heater comes hot within seconds.
Try this first, you can always add the pump if it doesn't work without one.
Perfect replacement for existing valve. My old one lasted 7 years, several reviews state a much shorter life expectancy.Just takes a few minutes to change.
Why not 5 stars? The Amazon price was the best around, but it is an lot for this valve. Make sure it is not working before replacing it.

A good product. It works as described and the customers are happy. A maximum of three of these can be used with one pump.Published 1 month ago by SARA BURGUN
Not much to say. The originally installed value no longer functioned properly, thus forcing too much hot water into the cold water supply. Read morePublished 1 month ago by James P. Keasey
Perhaps in the middle of installation is not the best time to write a review, but I am thoroughly frustrated with what should have been a quick swap of valves. Read morePublished 1 month ago by George Ganahl
