Key takeaways

  • Discharging near the foundation recirculates water
  • Sump water should not go to the sanitary sewer
  • Check valves prevent backflow into the pit
  • Discharge lines can freeze or clog

Ending too close to the house

A discharge that empties just outside the foundation soaks into the soil and can return to the sump. The pump runs more, wears out sooner and the basement stays wet.

Connecting to the sewer

Sump water in the sanitary sewer is generally prohibited and can overload the system. Keep it separate.

Missing check valves

Without a check valve, water in the discharge line drains back into the pit every cycle.

Freezing and clogging

Exposed or flat lines can freeze, and open ends can clog with debris. Burial depth, slope and an emitter help.

Discharging onto neighbors

Water must go where it is allowed to go. Discharging to a neighbor’s lot can cause disputes and violate local rules.

Quick answers

How far should a sump discharge go?

As far as practical, at least ten feet from the foundation, to a place that slopes away.

Why does my pump run all the time?

Often because discharge water is coming back, or groundwater is high. We can check.
