Frequently Asked Questions About Sump Pump Maintenance in Dover
A standard sump pump inspection and cleaning typically runs $125 to $250. Replacing a float switch or check valve usually adds $75 to $250 depending on parts.
With proper maintenance, a quality sump pump can last 7 to 10 years. Neglecting maintenance can significantly shorten its lifespan, leading to premature failure and costly replacements.
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.
Routine maintenance usually does not require a permit. However, if a significant repair involves altering the discharge line or replacing the entire unit, especially if electrical work is involved, a local permit might be necessary. We take care of all permit requirements for you.
Not every home does, but homes with basements, crawlspaces, below-grade garages or low-lying lots often rely on them. After flooding, wells should be tested and septic systems checked before normal use, since floodwater can contaminate both.
Our technicians are experienced with all major sump pump brands, including Zoeller, Wayne, Little Giant, Basement Watchdog, Liberty Pumps and more. We carry common replacement parts for many popular models.
Most quality pumps last seven to ten years. Pumps that sit dry for long periods can seize sooner, which is why testing counts during dry months.
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.
