Plumbing Guide

Where the sump pump discharges is as important as the pump itself, and routing the water wrong sends it right back to the foundation. The discharge should carry the water well away from the house.

Sump Pump Discharge Routing: A Downey Guide

The distance

The discharge line should end far enough from the foundation that the water soaks away instead of seeping back in. A long, straight run is the standard.

The pipe

Rigid or flexible pipe carries the water from the pump to the outlet, and it must slope downhill so it drains between cycles.

The freeze

A discharge that freezes at the outlet backs the water up into the pit, and an extension or a buried line below the frost line prevents it. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In Downey, winter freezes are the classic failure.

The outlet

The water should discharge over grass or gravel, not onto a neighbor's yard or the sidewalk where it ices.

The call
