That would be a problem....

Andy replies:
* None. *But , based on the post, I wasn't sure the OP was referring
to a "sump pump", *or a "pump that was used to pump out a sump".

"Dual sump pumps - check valve?

In the same crock I have two sump pumps on two separate breakers. "

It's one of the clearest posts I've seen.




* *People in different areas sometimes have different terminologies..

* JoeJ replied that they were both submersible, hence, I can't see why
a check valve would be needed for either....

" I had a failure on the primary pump and it seemed half
the crock was refilled by the remnants in the pipe draining back after
the backup pump shut off. "

That's why.




*I agree with your post...but I can't see why you replied to "me"
rather
than Joe J...


To correct the misinformation.
