"The work done was to clear a tub drain. An old and detached stopper was the real issue. They replaced the piping and did some dry wall work because they had to go thru our kitchen to get to the drain. Weâ re going to keep these guys on service for seasonal clearing of th drains. Thanks so much for the fair price and hard work."

"Adrian responded to our immediate issue right away (clear clogged drain). While on the job, I had him quote several other plumbing jobs I wanted to have done. He provided fair estimates and did a great job getting the work done. One job involved replacing two old valves on the main line coming into the house. For this work we needed to coordinate with the water authority to have the water shut off. Adrian was very accommodating while trying to schedule the shut off. He always returned calls and texts which made coordination easy and did a great job with the plumbing work. Will definitely use him again for any future plumbing needs."

"The reason I first hire them is to look at the boiler to reconnect the pipe so I can get it tested. The plumber came and he told me he does not do that work. They lock you in with the deposit and so you use it or loose it. The work that was done was okay. To reconnect two 1.5" drain pipes for $450.00 is a lot of crap. I would not hire anyone that would ask for a deposit, for it is the games that they play. Use it and they still charge you more for the job."

"We just moved into our house on June 1, and a few days later we had some strong downpours and our basement flooded! It turns out there was a sump pump which had been installed by CT Basement Systems a couple of years earlier. However, it was pumping the water into a gutter drain next to the house. This gutter drain was clogged, and the water was rising out of the ground and pouring into a window well, and from the well back into the basement!
Danny from CBS came out, and suggested putting in a perimeter system around that part of the house, which would have cost about $1800. I thought about it a few days, and figured that a better thing to do was to lead the water from the sump and gutters away from the house. So I had Danny come back and told him my idea, and he thought it would work. A month later he came back and installed the 4" drainage pipe and hooked in the sump and two gutters for a cost of $600.
It's almost a year later, and it's worked perfectly so far. We've had many days of heavy rain, and the sump pumps that water into the new drainage, and the water emerges at the end of the drainage pipe near the border of our property. Not a drop in our basement! I'm glad I thought of this solution - I guess I can't blame CBS for suggesting the more expensive solution.

French Drains FAQs, answered by experts

A bit of water in the bowl can help unclog a toilet, especially if you're using a plunger. However, if the bowl is full to the brim, you'll need to strap on gloves and remove some of the wastewater in a cup or container so it doesn't overflow when you try to unblock the pipe. If you're concerned about it filling further, manually close the flapper in the toilet tank or turn off the water supply to the toilet.

Yes, you can use hydrogen peroxide to unclog a drain. Instead of using a baking soda and vinegar solution, you can use baking soda with hydrogen peroxide. The process to unclog a drain is the same as with vinegar, but use 1 cup of hydrogen peroxide instead.

A washing machine should drain the water used during its cycle through a drainpipe and out through the house’s plumbing. This is the same plumbing that sinks and shower drains run to, and if the U-bend is installed correctly, it shouldn’t smell. The total drainage from the house is then integrated into the city sewer system or, if you’re in the country, dispersed into a septic tank.

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.
