Blow-By in DE Filter

[CarlD]

Operative word is MAY be oversized--you are getting blowback. That means something's broken, something's too low, or something's dealing with too much flow.

Life expectancy is of course determined by how much stress an object is under.

I disassembled the multi-port valve yesterday and discovered that one of the "legs" of the spider gasket had come loose. I dried it out using a hairdryer on low, and crazy-glued the leg back in place (only getting my fingers stuck a little).

The jury's out as to whether this will solve the blow-by problem, but I'm optimistic as the leg in question was between the outlet of the pump and the return line.
