I have a 3/4 hp sump pump with 1 1/2" PVC carrying the water outside.
The problem is that this pipe runs through a hold cut into a floor
joist. An awful lot of motor noise is transferred to the joist and,
hence, into the family room directly above. I have a check valve
with neoprene couplers installed about 3' above the pump, which I was
hoping would quiet this a bit. Maybe it does a little, but not much.
Is there a product marketed specifically for this purpose? Perhaps a
length of flexible (reinforced?) hose would help? Or maybe wrapping
the PVC in foam where it passes through the joist?
Any other ideas?
Can you push it away from contact with the joist with your
hand and silence the problem noise? Then try the foam. Or,
suspend it with nylon cord so that it doesn't touch the
joist. The flexible hose might fix it also. Or some
Go to your local supply place and look for the soft rubber
couplers; put one between the pump and the pipe; it'll help a
lot. Then take the place wher it goes thru the wood and somehow
fasten it securely against the wood so it can't bounce or move
around. Worked well here.

I'm not sure but isn't 1 1/2 inches pretty small. I can't go check
now, but I think my pump is that big and it uses 2 inch pipe I think.
But mostly I agree with the others. Either make sure it doesn't touch
the joist or make sure it is firmly attached to one. The first if
Here I'm not talking about much noise ==> I have never heard my sump
pump before, in 22 years, but this year it is so wet that it runs a
lot, I guess. It's in the basement in the left front of the house,
and when I'm in my office on the left front of the second floor, I can
hear it start and finish. But There are no pipes or metal things
between the two places. Maybe the heating vent. But I've never heard

me know if you have posted also.
Well, you could connect a solenoid to the pump's switch that turns on
a very loud radio or cd player whenever the pump runs. Maybe get a CD
with ocean sound effects :)
However, on a more serious note, I'd put foam pipe wrap around the
pipe where it goes thru the wood. Other than that, all you can do is
find another way to exit the pipe from the basement without touching
Just a thought, but some of that "great stuff" foam around the pipe
Yes, the flex pipe could be quieter, but that stuff tends to spring
leaks as it ages. especially where it rubs against objects (like the
holes in your wood). I'd rather live with the noise than have a pipe
that might start shooting water all over the basement. I HAVE had
this stuff spring leaks, and it's no fun when you got to wade thru
dirty water shooting out of the flex pipe to shut off the pump.
One last thought. I am a farmer and am aware of clear soft plastic
milking parlor hose (milk line). The stuff is soft, very durable, and
quite expensive. But at a couple bucks a foot, how much do you really
need... Use solid pipe on the vertical run, and adapt it to the milk
line where it enters the wood. I think this would solve most of the
noise. Actually, any soft hose would be quieter than solid pipe.
Today we have wireless electrical devices, someday we will have
pipeless water transfer. Put that one in your pipe and smoke it.
