[C320-list] Air in Water Heater?

[Gene Helfman]

In the category of forehead slapping Duh moments, we had a similar issue
last year that I finally "corrected" by installing a new pump, figuring the
old one was malfunctioning.  Still wouldn't shut off.  Then I happened to
go aft for some reason and discovered the stern shower was slightly open
(something we never use because it's seldom warm enough here to want to
take a shower on the stern; must have bumped it when playing in the port
stern lazaret).  Turned it off and voila.  Problem solved.
