"Jared showed up on time and went right to work. Installing the back up water powered sump pump and new sump pump seemed quite involved to me, but Jared said it would be no problem to do it. I am completely satisfied with their service, and responsiveness. H. L. Bowman is now the only plumber I will use for all of my plumbing needs."

"After Hurricane Sandy, we had our sump pump system with a battery backup expanded a few years ago with additional curtain drains added. The price was reasonable and they did not try to sell extras that other companies tried to sell. We have the system and battery serviced once a year. They keep to their appointments times."

"SILA is never going to be the cheapest but if you want something diagnosed swiftly and fixed or replaced just as quickly, you can't go wrong with these guys. They were the only ones to correctly diagnosis and fix our ailing furnace three years ago, so we trust them. For this problem, they tried to get the old pump into working order (turns out it was the kind that needed to be oiled; the contractor, not SILA, who installed it along with a heavy duty basement dehumidifier, never told us it needed oiling for routine maintenance). The SILA tech did all the diagnostics on the drain hose (no blockage there) and then tried oiling the motor. It was running but not well enough to push the water up the hose and down the drain. A new pump was the last alternative. Within 20 minutes, the SILA tech replaced the pump with one identical to our furnace condensate pump, which never needs oiling. Everything is working fine now! They also have good coupons/deals when you get on their email/mailing list."

"Installation went well and have had no issues since, seems to be working well. Entire process from scheduling to installation went very well. Beats having to refill 2 humidifiers all winter and cleaning up the white dust mess. <br />"

FAQs for sump pump or interior foundation drains installation projects in Stamford, CT

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
