[C320-list] Troubleshooting Freshwater Diaphragm Pump

[Paul Rickman]

Try cleaning the filter on the kitchen facet. I'm assuming you are trying to use 
the kitchen
facet. Have you tried the bathroom and outside shower. Could be an air lock 
because
the outside shower has not been cleared, or a clogged screen filter on the 
kitchen side.

Subject: [C320-list] Troubleshooting Freshwater Diaphragm Pump

Having trouble with the freshwater diaphragm pump (cold and hot water system).  
Had similar problems once before, and it was a matter of cleaning the 
screen/filter.  Very little debris on the filter, but cleaned it anyway.  Used 
plumbers tape to make sure it sealed when re-installed.  Still didn't suck water 
through the system.  Both tanks full and free of debris/obstructions.


Removed the filter again and had someone flip the switch to see if I could sense 
any suction.  None.  Zippo.  Zilch.  I can't imagine any internal debris.  Do 
pumps like this just go bad?


The model that is on there is Shurflow 2.8 gpm, 45psi.


Suggestions would be welcome.
