Howdy,
First time well below freezing in my '99 25' Safari and, although I drained the FW tank, I did not run the Shurflo diaphragm pump to clear water from it. The obvious damage was cracked clear plastic on the inline filter on the suction side. I replaced the filter and still get no suction up from the tank (now half full (of water, not ice
). I removed and disassembled the pump itself and everything looks kosher -- no cracks or evident damage. When blown into or sucked on either the inlet or outlet side there is no air escaping.
Anyone have any further diagnosis suggestions and or tips on how to bench test the pump? Thanks.
