Question in ref to fresh water system (cockpit) in 2005 220 BR

Hello....I've got an odd situation and I can't figure it out....any suggestions or help will be greatly appreciated..

fresh water pump on....hand-held at stern works fine...sink works fine....bow hand-held.....sputters...the pump can be heard, but it pulsates....

if i turn on the sink or stern water, then try the bow hand-held at the same time....it works fine so long as either of the others are on.

the bow water and the sink water are from the same line....it t's at the sink, then heads forward...
...?????.....suggestions please.....thank you..Mike...

Interesting. Sounds like there might be some trapped air but that doesn't explain why it works fine once the sink faucet is flowing. Did this start happening all of the sudden? Did you recently run the tank empty? That will certainly introduce air into the system.

There is a pressure adjustment on the pump itself, but before you mess with that, I'd try to verify that there are no air leaks, especially at the T under the sink.

Check the screens at the faucets and the one on the pump. The faucet screens are just like at home, unscrew them and check for debris.

...thank you for the reply's...good information.......i'll get it worked out.....Mike..
