"They called back immediately from my initial message. They came first thing in the morning and by noon my new water heater was installed and up and running. They went over and beyond what I have ever experienced with other plumbing technicians.They explained everything up front and I found them to be highly knowledgeable. I would highly recommend this company and they have acquired a new lifelong customer based on their performance dealing with my situation."

"I posted an initial review on 2/21/19 on a job done on 1/11/19 to fix groundwater from coming into our basement. The drainage system and sump they installed was not collecting all the water that was coming in, as we had leaking from several areas along an uneven rock ledge. I had reached out to our salesperson by phone and email and never heard back, so I was very frustrated. About 3 weeks after I posted the review, I did get a call from Jeff Allen, one of the supervisors. To make a long story short, he sent out one of their waterproofing specialists to look at the problem. We had already hired an independent mason to try to remedy the problem but he had not yet had a chance to do the job. Jeff convinced me that CT Basement systems would do absolutely whatever it took to fix my water problem. I cancelled the independent mason. Danny, a mason from CT Basement Systems came out and used a very ingenious method to divert all the water to the originally installed water guard trough and then to the sump. It is working beautifully!! I think Danny is a genius and I am so impressed and thankful for Jeff's perseverance and kindness in making this happen. I am now a very happy customer."

"A soft wall due to improperly installed gutter by some other entity or homeowner caused water to constantly leak into the wall from the exterior roofline. This soft wall grow moldy and become riddled with pests/bugs. The contractor identified the potential issues, agreed to explore and open the walls and discuss the conditions, made sound recommendations for repair and did exactly what was noted in the repair (replaced a load bearing exterior wall, fixed the sill plate, completed the roof, shingles etc. and closed up the walls on the inside with insulation and sheet rock.). The work was timely, well done, the workers were clean as they did the job and kept the rest of the property clean. The manager of the job David Apel was and is an excellent communicator with phone/email/text and photos of processes and progress. I am going to use this company in my own investment endeavors on other properties and projects given the level of finished work, the timing and especially the level of detailed communication."

Sump Pump Installation questions, answered by experts

First, you can try unplugging the two sump pump cords, one for the motor and one for the float switch, then plugging them back in to reset the sump pump. You can also reset the sump pump by turning it off and back on at the breaker. Many sump pumps have a reset button, which you can press and hold for a few seconds to reset the device.

A sump pump battery backup can typically run for 6 to 24 hours. The factors that affect its runtime include the battery capacity and pump usage. 

When purchasing your backup system, take these factors into consideration to determine which system is best for your home. If you live in an area with frequent and long-lasting power outages, consider a longer-lasting backup battery.

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

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.
