    Ejection pump makes a loud noise when it ejects
    When the ejection pump is ejecting water/waste from the pit, it makes a loud clunking noise upon completion of pump cycle. Could there be air in the line or is there something else.

    Hi Phyllis:

    That noise is the CHECK VALVE... see image below. The typical check valve installed in these ejector systems can be a bit noisy, to say the least.

    You can order a quieter check valve and get it installed... should reduce the noise quite a bit. Check them out here:

    A.Y. McDonald Mfg. Co. : Plumbing : Sump & Sewage Check Valves : Sump & Sewage Check Valves

    Another kind is the SILENCER check valve:

    Back to you...
