Vibrating discharge pipe from my sump pump
Posted by Terri Van Den Eng on March 28, 2002 at 15:07:29:
Ever since I replaced my old sump pump with a new one the discharge pipe coming from the pump rattles & vibrates very noisily. There is a check valve attached to the pump and this never occurred with the old pump. I think there is an airlock but I don't know how to solve it and it's driving us nuts. Should we be putting an additional check valve in the line somewhere? Please help?
