So I have a problem. After many years of repressurizing loops on a yearly basis from other installers I have one that we installed 2 years ago that is losing pressure.
Every 6 months I recharge it to around 40 lbs and when I return it is down to 4 or 5 lbs. It takes about 5 seconds to get it back to 40 so I can't be losing a lot if any liquid. FYI it is a 10 hole verticle system. My question is, other than digging it up can I try a non pressurized system by adding a tank and changing pump flow and would this work as well as a pressurized loop. IMO it would give a better ideal of liquid loss also.
