    2556 fresh water problem-gctid778758

    Hi,

    Have a look at my YouTube videos made today both are much the same only ones a longer version.I've only had the boat 2 months and the problems not really a major problem, more of a niggle so I've not looked too much into it.

    It's the tap water isn't a constant flow. The pump appears to be working however I'm not familiar with the whole system. Hot water is from a 240v immersion heater and through a calofifier off the engine. I'd expected 2 separate pumps which may well be the case and if there are 2 pumps then there wired through the 1 switch which may or may not be the norm.

    Best to check out the vids which show exactly what I mean.

    Has anyone had the same problem or know a solution.

    Thanks

    only 1 pump you should have in your boat.

    pressure is not building up, pump/pressure swith malfucntioning most likely

      Normally there's only one pump in the system. The pressure side of the pump has a Y-fitting that sends water to the cold side of the faucets, as well as to the hot water tank. These systems usually have some pulsing, but yours appears to be excessive. I believe that your pump may have a bad pressure sensor. You may be able to obtain a rebuild kit or simply replace the pump with a new one.

      If you want to have smooth water flow, consider installing a water pressure accumulator, or a variable speed pump.

        Agree, pump or pressure switch (on pump) issue. Here's what the plumbing looks like on mine.

          Thanks for quick replies folks. Is there any specifics I should look out for when looking at pumps or is it just a generic 12v pump with pressure switch?

            Several pump manufactures to choose from. Make sure it'll hook up to your existing plumbing and you'll want at least 50-55 PSI of pressure.

              Some pumps have an adjustable pressure switch, check for that and adjust if you can. Also, those "Whale" brand faucets are crap IMO, but check for obstructions in there as well.

                I hated the water flow in my 2556. I installed an accumulator pump from Lowes. I teed into the system right after the pump using household hardware. Easy install, low cost and great return. I padded it with thin rubber and hid it next to the hot water tank.

                  You have a screen type filter in your system somewhere between the tank and pump. You may also have an additional filter that may be a cartridge type of some sort. One or both of these could be just about plugged.

                    Agree with PcPete, check the filters.

                    Also, I Had a similar issue on my system, the o'ring seal on the strainer was leaking and sucking air into the system.
