A year or two back I posted about how when my sump pump would shut off
I would hear a very noticeable CLUNK. I thought it was related to the
check valve I had. Turns out I was right. I had tried a Flo-tec and
then a Zoeller check valve. Both were the same basic design and were
'clunkers'. Recently I just got a Campbell #B-0823-15C spring
loaded check valve ($23 shipped from Acehardwareoutlet). It's great
and now there is no 'clunk' whatsoever when the sump pump shuts down.
Just wanted to give some feedback to the group in case anybody else is
looking for a quiet check valve that works.
Another neat thing about it is that the body is clear so you can see
inside the checkvalve.
I can hear our "cluck" valve anywhere in the basement or 1st floor when it
does it's thing. I'd like to give this a try but have never changed a check
valve before. Does it just screw into the pump body?
No, it doesn't screw in to you existing pump. You need to glue in
some union type fittings to your PVC. It's a little work but when you
want to replace the valve it's really easy to just unscrew the hand
nuts, pull out the old valve, replace it, and hand tighten the nuts
