Two weeks ago, I noticed air in our water line. It came mostly in small spurts but greatly increased when the toilets were filling.
The plumber suspected the check valve at the submersible pump. He pulled the pump, but everything was fine. He then tested the well lines by pressurizing with air and noted no leaks. Pitless was replaced 1 1/2 years ago, and no wet areas were observed around the well head. The plumber is comfortable that it is fine.
He checked out the pressure tank, and determined everything looked and functioned properly. It maintains 20psi. The tank fills and there is no drop in pressure without water usage.
He then attempted to check the line from the well head to the tank and advised that he was able to pressurize with air, and that once removed, pressure dropped quickly. He attempted a second time to fill, and was unable to do so. With that, he advised that the problem must be line between wellhead and house which will require digging up my front yard.
After he left, I had no air in lines for over two days, but the problem returned, mainly at the toilets as they are filling. (In the interim, a friend thought could be issue with hot water heater and bad thermostat--so checked that out....sounds crazy but feasible...nothing there).
They are coming to dig up my yard in a couple of days, Today, I am having no issues with air in the line. The lumber is trustworthy, but I am extremely stressed with digging up my yard and not being close to 100% sure if that is the problem. Has anyone ever experienced this issue?
