"Inspection of a previously installed sump pump system (primarily the sump pump). Inspection found that it seized up and wouldn't have functioned. Replacement made - and very fortunately - since when the pump is needed, it IS needed. It wouldn't have been good to have a flooded basement or have an upcoming flooded basement."

"Amazing. YES - you pay a lot - but they rocked, their solution rocked, and the installation was flawless. We just built a brand new home and the builder put in the cheapest 24" deep sump pump possible. We live in an area known for basement flooding so I did my research - had several companies come in - and settled on Connecticut Basement Systems. But my LORD - expensive. But now I know why. Their crew of 3 showed up and laid down plastic mat from our front door all the way down to the basement (at least 200'). It was over kill - but then I saw why. They had to dig a 36" deep pit and a wider hole - and brought up all the mess in buckets. NOT A SINGLE DROP ON THE BASEMENT FLOOR OR ONE THE WAY UP THE STAIRS. In fact - if you didn't see the high tech 3 pump sump pump they installed - you would have never known they were there. EVERYONE was super nice and answered all my many questions. I just spent a year in **** building a new home - and this was the best experience I've had with a contractor in 10 years. Pay the bucks - great product - great installation - great service."

"Andrew was great on time and personable. He knew what he was doing and even showed me the issues. He fixed what he was able to and advised me on what I need to do next since the next issue was not the plumbing. When I was urgently looking for someone to come fix the leak I had, everyone else was unable to make it the day of. Andrew made it in an hour from speaking with him. I would recommend his services to anyone needing a plumber."

Sump Pump Installation questions, answered by experts

Several indicators suggest it's time for a sump pump replacement. A key factor is age; if the pump is over 10 years old, its lifespan is likely ending. Performance issues are also clear signs, such as the pump running constantly, cycling on and off frequently, making unusual noises or vibrations, or failing to function at all. A faulty or burnt-out motor is another definite sign a replacement is needed. Additionally, if you notice any signs of incorrect installation, the pump should be replaced. For a definitive diagnosis, a vetted plumber can assess the pump and confirm whether a replacement is necessary.

Yes, it’s normal (and beneficial) to have a small amount of water in the bottom of your sump pit. It shows that your system is collecting groundwater, rain, and excess water from around your property—just like it’s supposed to. However, if the sump pit is always full, you might have a leak or a faulty sump pump.

A sump pump's lifespan is typically 7 to 10 years, though the general range can be anywhere from 5 to 15 years. The specific type of pump is a major factor: pedestal sump pumps last an average of 20 to 25 years, whereas submersible sump pumps last between 5 and 15 years. While pedestal pumps are less expensive to service, they are also louder and more prone to clogging.

Several other factors influence longevity, including the pump's quality, usage frequency, and maintenance schedule. A high-quality pump that is well-maintained in a dry climate may last for two decades, while a lower-quality, poorly maintained pump in an area with a high water table or frequent flooding may fail in six years or less.

Regular maintenance, including annual inspections and tuneups from a professional, can significantly extend the pump's life. It is time to consider a replacement if your sump pump runs constantly, cycles frequently, shows visible rust or corrosion, or trips a circuit breaker. As a preventative measure, many homeowners replace their pumps every eight years. It's also worth noting that a manufacturer's warranty can indicate expected lifespan, and some home insurance policies may not cover water damage from a pump that is past its recommended replacement date.

Start by calling a plumber if you want to install a sump pump battery backup. Talk to them about your situation and needs. Sometimes, electricians or waterproofing contractors will install a battery backup, and in that case, the plumber you call should be able to point you in the right direction.

If you notice any new sump pump noises, such as persistent clanging or gurgling, then you likely have a sump pump problem on your hands. Foul odors coming from the pump can also indicate problems. Additionally, if your unit turns on but doesn't pump water, you might have to address electrical problems. In any of these cases, it's a good idea to hire a professional to address the issue.
