    Sizing a water system pressure pump

    I put a Sea Tech / Watts quick connect fitting on the input to my pump to facilitate servicing and it seems to be airtight in suction, at least for now. Everything upstream from there to the tanks is barbs and clamps. @El Borracho I agree that it would be great to have a gravity prime but it's...

    Sizing a water system pressure pump

    TLDR version: I've got no pressure drop issues but it's probably because even without a dedicated accumulator, there's so much compliance in my water lines that I'm effectively still running with an accumulator. Before removing the dedicated accumulator, I found that priming usually worked but...

    Sizing a water system pressure pump

    So I pulled the accumulator out and there's no discernable difference in performance. That gave me room to install a water filter and everything is working great.

    Sizing a water system pressure pump

    I would imagine there's plenty of compliance in the ~100'+ of fiber reinforced clear poly water tubing running around the boat.  I thought about running copper but only just for a second  ;)

    Sizing a water system pressure pump

    Clime, My boat came with a fixed speed pump + accumulator and I left the accumulator in place when I retrofitted with the variable speed pump, figuring it would do no harm. However, it's a big fucker in a tight compartment below the sink and I'd prefer to use the space for a water filter. Other...

    Sizing a water system pressure pump

    My UP6/e freshwater pump is spec'd at 9A/12V (4.5/24) and routinely pulls 20A for a few seconds if I let the accumulator leak down. Built like a tank. Not cheap, but you get what you pay for with these.

    Sizing a water system pressure pump

    They go by both Marco and Mate. Italian made and very high quality. I have one for my domestic pressure water and another as a blastdown pump. Both have been exemplary.  https://www.fisheriessupply.com/browse?loc=2705577577&terms=mate
