Bux,

Thanks. My analysis also pointed at an air pocket in the system, perhaps at the top of the water heater reservoir.

We might be dismayed at times at the build quality of our RV's, but I think we should admit that the design is really rather ingenious.

Pressurized air pocket seems likely. Do you have that pump delay with hot water only or both hot and cold?

In my 5ver when I am not on city water when I turn faucet on it's a little bit before pump comes on as pressure starts to drop

As a side note, we usually turn off the pump (or city water connection) and relieve the pressure in the lines before we leave the campsite for any length of time. I doubt it happens very often, but I have a feeling that coming back to an empty freshwater tank and water all over the place might not be as fun as it sounds. :-)

That makes really good sense
