The check valve for my sump pump is noticeable noisier than it used to be,
it used to be just a "thunk" which was somewhat noisy but now it sounds like
it is chattering when it closes. I haven't been aware of the sump pump even
coming on for awhile (months?) so was wondering if there might be some
rubber in the valve that could have dried out. Whatever the reason for the
chattering I'm guessing that I need a new check valve. The check valve that
is there now is fastened solidly in the drain line which transfers the noise
to the whole drain pipe making it even noisier than it has to be even when
it is working correctly. Is there a valve available that is "decoupled"
from the drain pipe when installed or would it be practical to fabricate
some kind of flexible or soft material between the drain pipe and the check
my setup has a pipe raising from the pump to just out of the pit. the
check valve is mounted there. So I can easily change the valve by
unplugging the pump for a while. But I think this adds to the noise
since this length of pipe will always be empty when the pump starts.not
that big a deal.
That chattering is something that happens to solenoids that are making
a poor connection. I can not however think of a solenoid being used
on a sump pump. Either way, the switch is probably sticking.
Manually try to operate the pump (raise the float). That will tell
you if the pump works. Then, either way open the switch cover (unplug
the pump first), and clean the contacts with emory cloth or sandpaper.
Then spray the contacts with silicone spray lube and put it back
together and test it. If the switch looks burned, replace it. If the
pump dont work, you may have more problems. Usually it's a stuck
impeller, but you should hear the motor hum.

I just had the same problem and there is a solution. A plumbing
company in my
area just came out with a Quiet check valve a month ago.
My whole house would shake from the noise created by the check valve.
has dissapeared with this new check valve.
The company is Black Diamond Plumbing. Here is a link to thier web
Hope this helps!!!!
