Solved 25 Year Problem with Geo Heat Pump Well System
My home has 3.5T geo heat pump located on the second floor. For nearly 25 years I have endured noisy starts and stops due primarily to water hammer of the PVC open loop or “pump and dump” well system. The standard practice of Northeast Florida AC contractors is to use either a slow opening irrigation valve or something made by Taco that costs $200. I repeatedly purchased the Irritrol 205TF recommended by the local distributor for Bosch/FHP/TETCO. Despite many changes to piping, well, pump location, pressure, and addition of water hammer arrestors, I could never quite end the calamity of the starts and stops. I found a professor’s study online that recommended a ball valve and that led me to this US Solid. I have found the Holy Grail! This is it, perfectly smooth starts and stops every time. No need to clamp down all the pipes. No need for water hammer arrestors. Have over one year installed experience. Many hot days the system starts and stops 100 times. Please don’t tell the AC techs or go blabbing about this at the ASHRAE show. Sometimes DIYers do engineer solutions that the industry ignores.
