"Connecticut Basement Systems prides themselves on their superior customer service, and they really live up to that. Their communication, quality of products and service, and attentiveness to customer needs is unsurpassed. Here are a couple of examples of how they go the extra mile for a satisfied customer: They installed their basement drainage system around my existing heating oil tank, but as I'm planning to convert away from oil this summer, they offered to come back AT NO EXTRA CHARGE once the tank is removed, to reroute the drainage system. Also, I was scheduled for a 3-day project, which included the replacement of some flooring in my basement. On the day the project began, we reconsidered the need for the flooring, and asked if we could cancel that portion of the job. They could not have been more accommodating to that adjustment, and made the change with no questions asked or negative attitude, even though it significantly lowered the price of the project and eliminated a whole day of scheduled work on 2-days' notice. That sort of total customer dedication is rare. I recommend them highly."

"Excellent work.  Was refreshing to work with a contractor who did the simple things such as showing up when they said they would, completing work as specified, completing in a timely fashion and communicating all along.  AJ was great to work with and originally came out for drainage work and tying our sump pump discharge into buried PVC pipe to drain in the backyard away from the house.  We were also in process of running a gas line to the house and when asked if they'd be interested in excavating the trench, which was no small task at ~450 ft along driveway and several trees/stumps/rocks, AJ was more than willing to take on the job.  AJ coordinated with the gas company and dug the trench per their specifications and backfilled with sand all within a couple of days.
Once the gas line was installed, AJ and his team completed the drainage work which consisted of tying in sump pump discharge, three gutter downspouts and a yard drainage box to pick up excess surface water at a low spot near driveway.  The discharge was run approximately 100 ft to the rear of our yard and a pop up emitter was installed to keep all water away from the house.  All excavation was backfilled and top soil added and graded with seed and straw laid.  Grass seed began coming up within a week and has filled in nicely.  
Throughout the process AJ kept in contact with what was going on and what they would be doing next.  The work was completed faster than we anticipated and the crew kept the site clean each day when they were done.  AJ went out of his way to make sure we were happy with the work and made sure the job was completed to satisfaction including following up with me to make sure we were happy after the job was complete and he had already been paid.  The crew was great, worked hard and put in a full work day and then some everyday.  The were several challenges with this job including a tight work space with many trees, roots and rocks.  The crew took great care to make minimal disturbance to surrounding trees, shrubs, etc.  We were very happy with AJ and crew and would happily use them in the future especially considering the reasonable price.  We even had the neighbors comment on the quality of the work done and how fast the work was completed.

"It is very convenient, and reasonably priced.  The only thing that they could work on is the punctuality of the pick up times.  The rest of the experience was satisfactory.  My daughter has also used them.  I would highly recommend this service."

Sump Pump Installation questions, answered by experts

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

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.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

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.
