Intermittent water pump clacking
Second trip with our Jay Flight and having some sort of water pump issue. About 20% of the time when I open a faucet, after a few seconds of normal operation, the pump starts clacking really loud. I thought RV water pumps were impeller type but this sounds like a metal piston banging against the top of the cylinder, if it has one, in very rapid fashion. It started happening at the tail end of our first trip two weekends ago. Our dealer is now booking service visits for the middle of August so I'd like to figure out what's happening and if I can fix it.
