[C320-list] Hot water heater issue

[Chuck and Kathy Mueller]

Hi Paul -

I found that if you have the water system pressurized and then turn on the 
water heater, that it builds up a lot of extra pressure.  In my case, it 
blew a hose off and pumped all the water from the tanks into the bilge 
before I figured out the problem.  So now I shut off the water pump and 
relieve the pressure before I either turn on the heater or run the engine. 
That keeps the pressure down and might help my water heater to last a little 
longer.
