"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."

"The representative came on time and listened carefully to my thoughts of a split ductless system. He suggested full house central air and showed me how it could be done, have ducts i stalled and cost less than a ductless system. His experience of over 20 years as a technician as well gave me a lot of confidence. He made a general proposal and came back in a few days for my convenience and I signed the contract. The duct crew finished in one day and were careful, explained things and left no mess. Then the ac was installed and tested in one day. Again polite, clearly communicated. Once the system started up late spring I am so glad I did this! No more noise from room ac, no shutting doors to keep one room cool. The humidity is normal and makes a huge positive difference. I highly recommend HARP. I switched my heating system to them as well after my experience with the AC i stall. Thank you HARP!"

"Great. They called to make appointment. Called to let me know they would be there in 15 minutes, Were on time, professional, efficient. Due to house and plumbing being 50+ years old, they did have to find a part at the supply store but came right back and finished the job. They advised us to get the lower shut off valve fixed in the future and sent us an estimate. Very pleased and would recommend them to my friends.$199"

Sump Pump Installation FAQs, answered by experts

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.

Test regularly, clean the pump, and inspect the discharge line to ensure efficient operation.

If your sump pump isn’t engaging, it might be clogged with dirt and debris. Check to see if the fitting lid is loose and has been letting debris in. Next, check the float and make sure it’s not obstructed by rust or gunk, which results from insufficient maintenance. Tangled wires or damaged switching systems can also stop your sump pump from engaging.

The difference between an ejector pump and a sump pump lies in their purpose and design—an ejector pump functions to remove liquid gray water and soft solid sewage waste from your home. If you have a laundry room or bathroom in your basement, an ejector pump for your sewage tank prevents sewage from backing up in your washing machine or bathroom’s drains.

A sump pump is designed to remove excess groundwater that may enter your home, either due to flooding or periods of heavy rain.

There are several things you can do to maintain your sump pump and prevent sump pump problems. For instance, keeping a lid on your sump pit goes a long way in protecting your pump system from silt, sand, dirt, and other debris. When water drains from the outside, such as along your foundation, or with melting snow, water runoff often brings sediment with it. 

Also be wary of corrosion, particularly if your sump pump system is made of metal. Keep an eye out for rust and have it inspected regularly by a plumber or sump pump technician.
