Fresh water flow problem

[Mvillalva]

Hello everyone. New member to the group and looking for some possible ideas on an issue. 3100 SE getting prepped for the summer and found no water flow at salon sink and low flow in the vacuflush toilet when pedal is raised. I have strong steady stream at the head sink, at the cockpit bar sink and at the swim platform shower head. Thanks.

Remove and clear the faucet aerator.

Thanks. Mmwjr. That was the first thing I tried. No joy.

With the aerator removed do you get water flow? If not try disconnecting the supply lines to see if you have flow there.

No water at all with aerator removed. Disconnecting the lines is next. I'll check from water heater forward.

I have a somewhat similar issue with our 3100se, low hot water flow in galley cold ok hot and cold water ok everywhere else. Still trying to track it down.

It's one system. One Pump. [Tank -> Pump -> cold lines to faucets and water heater. Water heater lines to hot side of mixing valves.

If the cold faucets are good, but not the hot, there is an issue at or after the water heater. IF there is good flow to some cold faucets, but not others, there is an issue in the mixing valve, aerator or pipes themselves.

Start with the pump. Make sure it's getting full voltage and that the pump isn't slow do to corrosion on the connectors.

From there you have to follow the system. A blockage in the pressure system is incredibly rare. The only place it typically clogs is the aerator.

You might have an opening in the system somewhere, however you would hear the pressure pump cycle on and off periodically if that were the case.

Another thing you could try is connect the boat to dock water if you have a regulator on your boat. By doing this you bypass the pump and tank. If you have good pressure then your pump is bad.
