    Don't Sink the Boat When Flushing

    By Bonnie

    from Acapulco, Mexico & Texas

    About Me Avid Do-It-Yourselfer

    Pros

    • Durable
    • Easy To Install
    • Easy To Use
    • Perfect for marine head

    Cons

      Best Uses

      • IDrain below water level

      Comments about Marelon Vented Loops:

      This keeps the boat from sucking water back into a drain that originated below the water line. The vent kills the siphon. Install this on a drain line that needs to pump overboard. Properly installed 10 or more inches above the waterline (when the boat is fully loaded) by raising the height of the drain to attach it to the vented loop using worm gear hose clamps
