Quote from: waughoo on July 13, 2024, 09:30:27 AMI have a continuous run of bilge pump hose with no "wye". My hose just loops up high above the waterline (and is anchored there) for anti-syphon purposes. That "anchor" point came loose once and it was back-flowing whenever stern dipped below the water. So check everything carefully back there. The POs over the years, may have changed things a bunch.Quote from: Jon W on July 12, 2024, 01:06:44 PMFWIW I used Trident 147 VAC HXD Bilge and Livewell hose. It's a smooth bore extra heavy wall hose that's clear with a black helix stripe.
Jon's suggestion is what I used when replacing my sump hoses. Mine were so brittle that seemingly gentle shifting caused them to snap!! I replaced the line from the transom exit to the above water line loop wye with the wire spiral exhaust hose and then switched to trident 147. As reported above, that thruhull at the base of the transom is underwater a LOT even in relatively calm sailing and motoring conditions. It's likely best to use the good stuff.

I'm most interested in how you confirmed it was the guage, as I am currently dealing with exactly the same symptoms as you.
