Waterlogged Compression tanks
Just visited a job site where two large 80 gallon compression tanks are getting filed with water . It seems every 3 weeks or so after tanks are drained they refill and must be drained. The installer added a water meter to the fill and less than a gallon of water has been added in the 3 weeks since they were last drained, but tanks are nearly full. The system has NO air separator at all and the line to the expansion tanks is directly off supply header. The tanks show no evidence of any water leaking at all.
I am thinking that the tanks either have pinhole leaks in the tanks or perhaps the gauge glass washers are leaking air. Any other clues... AS I indicated there is no visible water leaks and no evidence on the meter of water added. The contractor wants to replace the tanks with a single large bladder type expansion tank. I also encouraged them to add a Micro-bubble type air separator.
