Battery Backup System Testing in Renton, WA

A power outage during a heavy storm can leave your primary sump pump useless. Our maintenance service includes complete testing of your battery backup sump pump system. We check the battery charge, verify the charger's function and confirm the backup pump activates when the main power is interrupted. This dual protection is vital for homes in Renton, WA where power interruptions can coincide with severe weather.

Crawlspace and Window Well Pumps in Renton, WA

Not every sump sits in a basement. Many homes with crawlspaces or deep window wells use small pumps to clear runoff. We service these smaller units, clear their screens and confirm the discharge reaches daylight or an approved drain. Hard freezes are infrequent on the west side of Washington, but short cold snaps catch many homes with uninsulated pipes off guard.

Discharge Line and Check Valve Service in Renton

The discharge line carries water away from your basement, and the check valve prevents pumped water from flowing back into the pit. We inspect these components for blockages, leaks or damage. A faulty check valve can cause the pump to short-cycle, leading to early wear. We make sure these vital parts are functioning correctly to maintain an effective water removal system for your Renton residence.

Float Switch Inspection and Adjustment in Renton, WA
