I've made the connections as handtight as I can, but they are not 100% airtight. Does this sound like a reasonable theory?
The obvious way to test this would be to seal the connections at the pump. My only fear is that once I do that, I won't be able to remove those connections, and I'm afraid if I have a warranty issue that I wouldn't be able to return it. Any advice? Should I bite the bullet, seal the connections so they are 100% airtight, and hope it works?
On the intake side, all joints in the pvc need to be glued to keep air out. If air gets in, it will break the suction on the pump. Seal the threaded fitting to the pump basket with either teflon tape or teflon pipe dope to be sure air doesn't get in there. The top of the pump basket may need a little o-ring grease to keep it from leaking, also.
