Low dockside water pressure on 3200 SCR

[jamanati]

My 95 3200 scr has a new problem. Seems that when I am connected to dockside water, I have low water pressure at my sinks and shower. If I use the water from the water tank (via the water pump), the pressure is great.

The pressure from the dockside hose is fine as well. I'm thinking there is a check valve (somewhere) that may be faulty or stuck.

Anyone have any experience with either where it may be or what it looks like?

Thanks.
