This valve was the answer to our problem.

The valve was delivered promptly as promised, and completely cured the knocking problem we were having with our water to air heat pump. Fingers crossed for the longevity.

50-50 on thoughts

I replaced my first power head unit in February 2016. Previous valve and head had to be over 3 years old. I just now had to replace it again. Once the replacement came, installed, and nothing. Looked closer at it and found a wire not connected to terminal 3! Really hoping 3rd time is a charm and get back to lasting awhile.

Two failures in 8 years
By Verified Buyer on 2/23/2016
Hopefully the G3 version lasts longer than the G2 version. I am on my 3rd replacement. Why can't they just sell the valve without the electric valve control? Would be less expensive. I now have two good (spare) controls and no good valves.

By Hurley G. (from Franklinton, LA) on 4/29/2013
I have two geothermal units in my home that are about five years old and I have had to replace both valves twice and am looking at replacing the valve on one of the units for a third time. I have a serviceman coming tomorrow. They keep replacing the whole unit. Why can't they just replace the "power head" for less than half the price?
