I installed a sewage pump for a basement bathroom, and I hear a loud noise every time the check valve closes. Is there any way to reduce the amount of noise from the water hammer? I have the pipe secured to a joist, but it doesn't seem to help. I swapped out the Flotec check valve that had clamps securing it to the PVC with one that's larger (white plastic) with compression fittings, and that didn't help either. Any information would be greatly appreciated.
