[C320-list] Domestic fresh water pump leak

[Mike Mellon]

Thanks for the info, Frank.  I have ordered the SHURFLO 94-238-04 
diaphragm rebuild kit, from Defender  The tech support person at Shurflo 
(Tel: 800-424-9776) suggested this is the most likely source of the leak 
problem.  We'll see in a few weeks when I get the part and install it.  
If that doesn't work, I'll replace the pump entirely.
