A failed sump pump can flood a basement or crawl space after a storm. Drain Doctor handles sump pump repair and installation for Covina-area properties that need reliable flood protection—including check valves, discharge lines, and backup options when the primary unit is unreliable.
How we help
We test the switch and motor, clear debris from the pit, inspect the discharge path, and repair or replace the pump as needed. When a new install makes sense, we size the unit for the pit and expected water load and leave you with a clear maintenance path.
