New Sump Pump question
"DCM Fan" wrote in message
...
I just installed a new sump pump, auto, submersible w 1.5" drain pipe
fitting.
The drain pipe rises 8 feet, with a check valve 2 feet from the pump.
To expedite things, a had ANOTHER check-valve screw-in thingy sitting
around,
which I screwed into the pump, then connected the 2' of pipe to that.
So, I have Pump cheesy check-valve screw-in thing, screwed directly
into the
pump 2 vertical feet of 1.5" pipe industrial-strength check-valve
6
vertical feet of pipe 90-degree elbow Exit.
Is it OK to have the double-check-valve thing going on?
BONUS QUESTION: Upon re-assembly, I found a small felt-like cylinder
thing,
like a small paint roller in the bottom of the crock. What could that be?
(Someone else installed the pipe recently, including the
industrial-strength
check-valve, but left the sump replacement to me...)
TIA,
Bob
I personally would not use 2 check valves.
