Frozen Discharge Lines

In Elgin, IL, about 32 inches of snow falls in a typical year, and a discharge line can freeze or ice over at its outlet. Signs include a pump that runs without lowering the pit, water backing up the line, or ice at the outlet. Keep cords and outlets dry.

Clearing a frozen line
A plumber may trace the line to the frozen section, clear or thaw it safely, replace cracked pipe, check the check valve and confirm the pump empties the pit again.

Stopping a repeat freeze
Advice depends on the line's slope, how far it runs outdoors and where it ends. Ask whether a freeze-relief fitting suits the home.

Call about a frozen discharge line and describe where the line exits and the pit level.
