"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."

"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."

"I texted him and he came out after 30 minutes. It was super quick and amazing. He showed me that it was just a silt underneath the pump and also showed me what to do for future problems. It was a quick job and he's our go to guy for a plumbing work."

"They came out on a weekend and we're our saving grace during one of the most frustrating experiences we've had in this house. We couldn't use any plumbing without flooding the basement with sewage, it was early stay at home days, and we felt like we would go mad. They showed up and gave us an price for replacing the broken pipe, and set in to work. They worked for the entire weekend essentially, staying extremely late at night and showing up early the next morning, and at one point driving far out at night to get supplies since their usual local place was closed (again, quarantine time) . The reason it took so long was because after opening up the floor to get to the end of the pipe to replace it they found more damaged pipes, and replaced those as well. By the end of it they had spent the entire weekend on a job they expected to only last an afternoon, had charged us not nearly enough for the amount of work they did, and fixed a leaking bidet we had for free for good measure. They also advised us to do camera scan to look for any other problems, which they couldn't do until the water drained out, and even did an initial mop of the basement (which, remember, sewage flooding). I'm honestly half convinced these people are magic helpful brownies or something, it's unreal how helpful they were! Somehow our drier which has not succeeded in drying clothes for over a year has started working in a single cycle since they left, despite the fact they didn't even do anything with it, and in fact specifically said they don't do driers and offered to recommend someone else when we mentioned it. Suffice to say, I cannot recommend them highly enough"

"The service person came promptly and was able to install the faucet and a trash disposal unit that had been taken out when the countertop was replaced.  There was a slight adjustment that needed to be made in the piping for the trash disposal unit.  Everything was done in a professional manner.  However, the price was a bit high in my opinion to just put back what was disconnected.

Sump Pump Installation questions, answered by experts

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.

Sump pump repairs are typically handled by plumbers or waterproofing specialists who are experienced in handling basement and foundation-related issues. Plumbers can address issues like clogs, electrical problems, and mechanical failures, and waterproofing professionals may be ideal if the sump pump is part of a larger drainage or waterproofing system. 

Some people may also call on a general handyperson for minor sump pump repairs. However, for complex problems, hiring a certified plumber or waterproofing expert ensures the work is done correctly and prevents further issues.

You should be fine. Most high-grade grinder pumps have a 24-hour holding capacity within the tank. You can continue to use the facilities so long as the power outage does not stretch into days. In a worst-case scenario, attach a generator to the grinder pump, providing it has sufficient electric capacity.

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

The life span of a water pump ranges from five to 15 years on average. Regular maintenance can extend its life. If you notice significant drops in performance, strange noises, or frequent malfunctions, consider a water pump or well pump replacement. Always get in touch with a professional if you're concerned about yCan I install a water pump myself?our pump's condition.
