Ok, I tempted fate. The fridge works....and I just replaced the galley
pump, so the self-contained water system works.....so I decided to hook up
the van to the house water system with a hose.....

I turned on the water....and BZZZZZZZZZZZZZ.....the system buzzes like,
well a bunch of killer bees. When I turn on the water inside the van, the
buzzing stops....

Is it supposed to do that?

Or, like they said in the "Killer Bees" sketch from the old Saturday Night
Live..."Even Reggie Jackson buzzes off!"
