    Help! Low cabin water pressure

    2008 36 Sedan Cabin. Dock water pressure is fine but pressure from tank is terrible. Checked all the usual suspects - replaced pump, cleaned faucett strainers, checked for kinked or leaky hoses, nothing!Hot water pressure is bad as well. Any ideas?

    Re: Help! Low cabin water pressure

    Do you have a strainer or filter before your pump? I have a strainer between the water tank and the F/W pump. I have to clean the screen in this strainer a few times every boating season. I get some kind of mineral build up from the water. It is a white solid crusty material.

    It has a strainer at the pump and it was clean. Pump was changed with no effect. In fact, the original pump was tested and it works well.

    I had low pressure & it ended up being the faucet in the galley sink. It was plugged inside. I just replaced it & all was fine
