Thanks for your reply, SteamKing. There are test method procedures for doing a pressure test. My research has found several around the country and they all list pretty much the same procedure for doing it. The calculation for getting the ALLOWABLE water loss over the 2 hour test is the same...
Thank you for your reply, mfb. I am sure there is air in the system. The pressure test will have to be performed again after bleeding the system to try and get the air out. I don't think the pvc pipe itself would expand under pressure enough to effect the water loss calculations, but movement...
