    I have two failing vacuflush pumps in my Hatteras in the engine room. I've found Dometic and Sealand have exact replacements but naturally, everyone planned out a big long weekend for me and nobody has these in stock. I have found regular macerator pumps and wondered if I can simply replace the Vacuflush with a straight up macerator.
    This is a direct replacement that I found but again, nothing I can get today and fix the issue.

    The vacuum pump has 4 duckbill valves, the black pump pictured has 2.
    What is your failure?

    It's always a few days before a holiday that you go down to your idle boat, start cleaning up, checking this and that out, and when your about to walk aweigh, that last beer needs to be relived.
    Then the smile quickly disappears; The last issue on the boat,,, The Head..
    Why is it the Head always has issues rite before a holiday??
