This us excellent for power failure. Runs your primary pump and not backup pump. Prinary pumps more than backup pump

A couple of years ago, we had a bad storm and the power was out for days. I didn't know if my sump pump had a backup battery system in place in our recently bought house but I learned later that we didn't by observing the dirt that been found on top of our vapor barrier. I did my research and came across the demonstration video for the Pump Sentry and was easily sold. This was an investment that could/would save me a lot of money if I faced a power outage again. Installation was very simple and straight forward. A local company charges about $1600 buy and install this which is absurd. If you can get into your crawl space, you can install this yourself. Right now during my crawl space "renovation" I have this sitting on a crate until I have the area ready for wall installation but it's working as intended. After setup, I did a test run and unplugged the power from the sump pump to the house and pulled on the sump pump lever to activate it, and it came on as intended. I reviewed comments on what kind of battery to install it with and went with the Interstate 12V 110 AH SLA/AGM Deep Cycle Battery (DCM0100) which is supposed to supply 20 hours of battery life in the event of an outage. Just having this now installed gives me such peace of mind which is priceless when owning your own home. In the grand scheme, this is a small price to pay for your house's benefit. Crawl spaces are often neglected which can be costly to your home and even health. I feel very confident in my purchase and wouldn't recommend anything less than what the Pump Sentry can offer. Don't go any other route in backups if it can't produce or exceed these same results.

Cannot say how great the customer service was with our purchase. We actually damaged the SEC pump guard while hooking it up and the company was very generous in replacing it at no cost. Very grateful customer.

Im in the restoration business and im around water damages every day. Battery backup systems are ok but battery backup sump pumps are weak and wont last. This system however is excellent. My mothers basement gets water within 2-4 minutes of losing power and by the time i can get over there to start the generator its to late! This pump sentry pays for itself the very first time you lose power (when water levels are high). The avg cost for my company to extract water out of your basement then set up drying equipment to dry it out is $1500-$2500! This system + a battery + a battery holder + a metal shelf to put the battery on only cost me around $835! This system literally only takes 10 minutes to hook up. Your simply running your currently installed sump pump off the pump sentry system. Once the battery is connected to the pump sentry just plug the pump sentry into a wall receptacle then plug your current sump pump into the pump sentry and turn it on. UPDATE - My mother lost power from a snowstorm at 2am and the pump sentry immediately kicked on and began to work saving the day. Amazing product!

Was working extremely well until the power went out about two months ago. We had a thaw and a rain storm that put the power out. It kicked in like it should have but it the battery ran out from the continuous use for 4 hours. So the basement flooded. Bought a new battery the next day which was not easy since they were running out and it kicked in running well for about another 4 hours and that was it. The basement was flooded and has to be renovated . When the power eventually came back the invertor was dead! not lights no nothing. It was 5 years old and maybe it blew a fuse . How do I change it? Or it's done.
