TACO geothermal zone valve
I had two geothermal units installed in my home seven years ago. Since then, I've had to replace the TACO zone valves twice on one unit and three times on the other. I noticed my well pump was coming on and loosing pressure immediately even when the units weren't running. I had the repairman come in and he told me the valves in both units weren't closing properly. Now, that means the valves have to replaced again. Why can't TACO build a valve that lasts longer? This is very frustrating not to mention expensive.
