"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."

"Ron was very professional from the start to finish. I had a blocked basement drain repaired and a new day light drain installed to this basement drain. The work was outstanding. The basement doesn't flood anymore. Thanks Ron for a great job well done."

Sump Pump Installation FAQs, answered by experts

To maintain your sump pump, start by checking it every three to four months to ensure it’s in working order. Clear any debris from the pit because blockages can prevent the pump from operating efficiently. You should also test the pump by pouring a bucket of water into the pit. If it turns on automatically and drains the water, it’s functioning correctly. Inspect the discharge line for clogs, and ensure it directs water away from your home. Once a year, clean the pump itself, and consider having it professionally serviced for optimal performance.

3/4 HP is stronger than 1/2 HP. Horsepower measures how much weight can be moved and how fast, or the power needed to move 550 pounds one foot in one second. 1 HP equals 550 foot-pounds per second, so the higher the horsepower, the heavier the load it can lift. While 1/2 HP is a standard, powerful option, 3/4 HP has the extra strength to handle heavier, larger doors with ease.

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.

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.

To test for toilet leaks, use water coloring in the water tank and see if the water slips into the bowl from the tank. This test will indicate if there’s a problem with the flapper or refill tube. You can also put water coloring in the bowl of the toilet to see if there is a leak there. If there is, you should see the colored water on the outside of the toilet bowl or on the floor.
