Check Valve Replacement

A check valve sits on the discharge pipe above the sump pump and lets water flow out but not back. When it fails in an Elgin, IL basement, pumped water drains back into the pit, so the pump short-cycles, wears faster, and you may hear water rushing back after each run.

Typical check valve work
The work may include cutting out the old valve, fitting a new one in the right flow direction, tightening unions or clamps, and running the pump to confirm the valve holds.

Valve only, or new pump?
Whether a valve alone fixes the problem depends on the pump's age, how often it cycles and the discharge line's condition. Ask the plumber to explain before work starts.

Call about a check valve and describe any thudding, rushing water or rapid cycling.
