Sump pumps are usually located in your basement or crawlspace and they keep your home safe from structural damage to your foundation that can come from excess water after a heavy rain.  They are usually electrically powered but you can get a battery backed up sump pump so in case of a power outage during a storm your sump pump will still kick on. Sump pumps are equipped with a check valve which prevents water from back flowing back into the sump pump after it has been pumped out. Old and worn out parts can fail which could lead to a flooded basement if not corrected. If ever you notice something off with your sump pump or if it's not working give us a call right away so our technician can get it back to working properly. Homeservice Plumbers is open for you 24/7!
