"I called Atomic Rooter around 2:30 pm and they had someone out at the house by 4:30 pm on the same day.    The piping on the faucet copper line had burst last winter and the entire faucet needed to be replaced.  Access was from the outside and I had already removed the external cedar shingles and cut the access hole before calling for service.
Normally, I do these types of repairs myself but the piping was in tight quarters.  There was a flexible water line connected to a  fitting with the frost free faucet attached.    One look told me it would be better to have a professional do this job to avoid a potential mistake on my part and damage to the flexible line and fitting.   
The service technician made the repair in about 20 minutes without damaging the flexible line.    The new frost free faucet is sturdy and won't be needing future repairs.   I was also given some tips on how to the freezing problem in the future.

"They ran interior piping to a sump pit. They had to break up the floor install the piping. Install a sump pump pit so the water was pumped outside. Then recement the trench. This is the second time I have used this company and I highly recommend them. I have had two different crews doing the work and both did an outstanding job."

"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."

Drain Pipe Installation questions, answered by experts

Simple blockages can be cleared using household plungers or manual snakes, provided no severe plumbing issues exist.

French drains may fail when they become clogged with soil granules that slip through the pores of the landscaping fabric and through the holes in the pipe. 

Over time, this debris can build up inside the pipe and prevent water flow. To prevent this failure from happening, regularly flush out your French drain and keep debris away from the inlet grate.

If your washing machine drain is clogged, that isn’t a good sign. Unlike toilet drains or kitchen sink drains, there isn’t matter that is easily broken up with a plumbing snake, and more care is required. If you’re in an old house or have mineral-rich water, there could be a buildup inside the pipe. Either way, if the blockage isn’t obvious and doesn’t dislodge with a snake, you need to call a pro—otherwise, you risk damaging integral plumbing.

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.

On average, a plumber will take 30 minutes to two hours to clear a clogged drain. If the clog is located close to the drain or an access point and isn’t severe, the project will take about half an hour. If the clog is deep within your plumbing system or is a severe blockage, it can take two or more hours to remove the clog. For this reason, main line clogs tend to take longer, usually between two and three hours.
