Float Switch Repair and Adjustment in Ontario, CA
The float switch is the most frequent reason a sump pump fails to start. Tethered floats can tangle on the pump body, and vertical floats can stick from mineral crust or debris. We clean or replace the switch and set the on and off levels so the pump does not short cycle. Electronic sensor switches are an option for tight pits where floats get hung up.

Submersible Sump Pump Service in Ontario
Our team is experienced in maintaining submersible sump pumps, a popular choice in Ontario due to their quiet operation and compact design. Maintenance involves pulling the pump to inspect the watertight seals, clearing the intake screen and checking the internal components for corrosion or wear. We also verify the electrical connections are secure and free from moisture, preventing electrical hazards and supporting longevity.
Crawlspace and Window Well Pumps in Ontario, CA
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. Mountain and high desert communities in Southern California do get hard freezes, so pipes there need insulation and proper winter care.
Pre-Storm Season Pump Testing in Ontario
When heavy winter storms do arrive, runoff can overwhelm yard drains and storm systems, and burn areas can send debris into low-lying homes. We test your pump ahead of the rainy season by filling the pit until the float trips. We watch the pump empty the basin, listen for grinding bearings and measure how fast it cycles. If the pump struggles, you still have time to fix it before the first big storm.
Check Valve and Discharge Line Service in Ontario, CA
The check valve stops pumped water from falling back into the pit when the pump shuts off. A failed valve makes the pump run twice as often and wears out the motor. We test and replace check valves and inspect the discharge pipe for cracks and loose joints. We also make sure water exits away from the house so it does not soak into the soil around the slab or foundation.
Float Switch Inspection and Adjustment in Ontario, CA
The float switch is a critical component that tells your sump pump when to turn on and off. A stuck or improperly adjusted float switch can lead to the pump running continuously or failing to activate at all. During maintenance, we inspect the float switch for freedom of movement and proper calibration, making adjustments as needed to support reliable operation for your home in Ontario, CA.
Pit Cleaning and Debris Removal in Ontario
Long dry stretches let dust, sand, gravel and leaves settle in the pit. That debris can get sucked into the intake screen and jam the impeller. We pump down and scoop out the basin, rinse the intake and inspect the pit liner for cracks. A clean basin helps the pump run cooler and last years longer.

Battery Backup Sump Pump Maintenance in Ontario, CA
Many Ontario, CA homeowners rely on battery backup sump pumps for protection during power outages. FKM Plumbing provides essential maintenance for these critical systems, including testing the battery's charge and health, inspecting the backup pump's operation and checking the charging system. This keeps your home protected even when the primary power source fails, a common concern during severe storms.
