Thread: Air in Water lines

  1. #1

    Default Air in Water lines

    A friend of mine said his power went off a week or so back, and now he's got air in his water lines to his house— He is on a well. I told him before I put a oneway valve on my house, with the well 200 feet down the hill, if I didn't "catch" the problem in time my whole house, (including the hot water tank) would drain down, but after a few days the air was gone...

    So, what are the many possible ways for air to get in your water lines?

    Thank you in advance!

    The usual/primary cause is a leaking check/foot valve in the well; all submersible pumps have one in/on the outlet. Adding one at the pressure tank hides the symptoms of that or other leaks between the additional check valve and the one in/on the submersible pump.

    CAUTION, as of Nov 12 2013 all YouTube videos showing how to rebuild a Clack valve have an error in them that can cause damage.
