"SILA is never going to be the cheapest but if you want something diagnosed swiftly and fixed or replaced just as quickly, you can't go wrong with these guys. They were the only ones to correctly diagnosis and fix our ailing furnace three years ago, so we trust them. For this problem, they tried to get the old pump into working order (turns out it was the kind that needed to be oiled; the contractor, not SILA, who installed it along with a heavy duty basement dehumidifier, never told us it needed oiling for routine maintenance). The SILA tech did all the diagnostics on the drain hose (no blockage there) and then tried oiling the motor. It was running but not well enough to push the water up the hose and down the drain. A new pump was the last alternative. Within 20 minutes, the SILA tech replaced the pump with one identical to our furnace condensate pump, which never needs oiling. Everything is working fine now! They also have good coupons/deals when you get on their email/mailing list."

"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 hired Rich Because he took the time talk to me and explain the job and give me solid information. The hot water tank installation was very quick, efficient and neat. Rich and his co-worker were friendly, polite, and mindful of my cat not getting out. I highly recommend E and R Plumbing!"

Sump Pump Installation questions, answered by experts

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 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.

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.

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.

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.
