Discharge Line and Check Valve Service in Norwalk
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 premature wear. We confirm these vital parts are functioning correctly to maintain an effective water removal system for your Norwalk residence.

Float Switch Repair and Adjustment in Norwalk, CT
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.
Battery Backup Sump Pump Maintenance in Norwalk, CT
Many Norwalk, CT homeowners rely on battery backup sump pumps for protection during power outages. GLV Plumbing provides thorough 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 real concern during severe storms.
Zoeller Sump Pump Maintenance in Norwalk
GLV Plumbing is proficient in servicing Zoeller sump pumps, a widely trusted brand known for its durability. Our maintenance includes specific checks for Zoeller models, such as inspecting the cast iron housing for cracks, ensuring the motor is running smoothly and testing the float switch assembly for correct activation. We stock common replacement parts for quick repairs, keeping your Zoeller pump in peak condition.
Battery Backup System Testing in Norwalk, CT
A power outage during a heavy storm can render 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 ensure the backup pump activates when the main power is interrupted. This dual protection is vital for homes in Norwalk, CT where power interruptions can coincide with severe weather.
Check Valve and Discharge Line Service in Norwalk, CT
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 near the slab or foundation.
Submersible Sump Pump Service in Norwalk
Our team is skilled in maintaining submersible sump pumps, a popular choice in Norwalk 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 Norwalk, CT
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. When a deep cold snap is forecast, keeping the heat steady and opening cabinets on outside walls can help prevent a burst pipe.

GLV Plumbing services all major brands of sump pumps common in Norwalk homes, including Zoeller, Wayne, Little Giant, Liberty Pumps and Flotec. Our technicians are trained on the specifics of many models, providing expert care regardless of your pump's manufacturer.
The check valve is crucial because it prevents water that has been pumped out from flowing back into the sump pit after the pump shuts off. A faulty check valve can cause the pump to short cycle, leading to premature wear and higher energy use. Our maintenance includes checking its function.
A large share of homes in Connecticut use private wells, which can be acidic or carry iron, manganese, or radon that call for treatment. Where groundwater is hard, mineral deposits can build up on the pump's impeller and in the pit, reducing efficiency and possibly causing clogs or damage over time. Regular maintenance helps limit these effects.
Most local codes do not allow sump discharge into the sanitary sewer. We route discharge to the yard, a dry well or another code-approved location.
Most visits take 45 minutes to an hour. Replacing a check valve or float on the same visit adds a little time.
