Re: Grey water pump mystery

Thanks to everyone

Update. I disassembled the pump. The 2 month old parts looked fine.

It seems to be working again. Hopefully this intermittent issue will not resurface

Re: Grey water pump mystery

The output hose attaches to a plastic part that can be screwed off the pump. Inside is (should be) a joker valve that is important.

Also, for best performance, I recommend to bring the pump down so that the output flow of the pump is up instead of down.

There should be no strainer in front of this pump. Their slogan is that anything that fits into the suction side gets pumped out. For gray water you donít want a rotating pump (i.e. impeller, macerator) as any hair gets wrapped around.

Re: Grey water pump mystery

is your intake hose reinforced? if not it may be collapsing and closing off the flow?

Re: Grey water pump mystery

Intake hose is reinforced.
Joker valve on output is good.

I took apart the pump, again, and did some prodding and sucking. It appears the brand new flap valve on the intake is not seating perfectly. It seemed like it might have been a touch too long, so i trimmed it. I also put a light coat if silicon grease where it sits.

This created a very tight seal, and the pump works perfectly, for now. The grease will probably not last long, so i hope the trim solved the issue.
