I've had my 270 for several years and never had any problems with the freshwater pump, and winterize it every year. This year, the pump runs and builds pressure, but as soon as I open a faucet, the pressure drops to a dribble and the pump continues to run. I bet I need to clean the inlet screen or maybe there's a filter? So, where is it? I looked under the cushions fore and aft, maybe it's in the head? Is there an access panel I need to open to get to it? Thanks for the help!
 
On my 05 there is an access panel in the head under the sink. Simple 5 minute procedure.

Edit:Behind the panel will be an obvious filter housing. Simply twist a quarter turn, disassemble, and clean all the grunkis out.

Thanks. I saw a panel under the sink with 2 screws holding it in. That must be it. I checked the owner's manual and it says simply, the pump is in the bilge.
