"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."

"Amazing. YES - you pay a lot - but they rocked, their solution rocked, and the installation was flawless. We just built a brand new home and the builder put in the cheapest 24" deep sump pump possible. We live in an area known for basement flooding so I did my research - had several companies come in - and settled on Connecticut Basement Systems. But my LORD - expensive. But now I know why. Their crew of 3 showed up and laid down plastic mat from our front door all the way down to the basement (at least 200'). It was over kill - but then I saw why. They had to dig a 36" deep pit and a wider hole - and brought up all the mess in buckets. NOT A SINGLE DROP ON THE BASEMENT FLOOR OR ONE THE WAY UP THE STAIRS. In fact - if you didn't see the high tech 3 pump sump pump they installed - you would have never known they were there. EVERYONE was super nice and answered all my many questions. I just spent a year in **** building a new home - and this was the best experience I've had with a contractor in 10 years. Pay the bucks - great product - great installation - great service."

French Drains FAQs, answered by experts

There are several common signs that your main sewer line may be clogged. Key indicators include multiple fixtures in your home draining slowly, gurgling sounds coming from drains or toilets, and water backing up into showers, sinks, or toilets. You might also notice water backing up from the plumbing system's drain cleanout, water in your basement drain, or unexplained wet patches on your lawn. Foul odors, such as the smell of raw sewage or rotten eggs, are another common symptom. The most reliable way to confirm a main sewer line clog is to hire a professional plumber to perform a camera inspection.

It is generally not recommended to pour hot or boiling water down a drain to unfreeze pipes due to significant risks. In some cases, the sudden temperature change can cause more ice buildup or produce steam, which increases pressure and could cause the pipe to burst, leading to costly damage and potential burn injuries. While hot water might help with a partially frozen drainpipe, it is unlikely to thaw a completely blocked water pipe further down the system. Additionally, boiling water can damage plastic pipes over time. Safer and more effective methods include using a space heater near the frozen section or applying hot towels directly to the pipe.

If you don’t have a sewer cleanout, clearing out clogs can be extremely difficult. You would need to try to clear the clog from sink drains, but it can be harder to reach the clog all the way in the drain line. A sewer cleanout makes it much faster and easier for pros to clear clogs from your main sewer line.

Bleach is generally not recommended for your shower drains. Although diluted bleach can technically help clean your drain, it will not unclog your pipes. In fact, bleach can harm your plumbing system because it’s so powerful. The bleach can change the color of your sink and even corrode metal pipes and fittings.

Often, people reach for bleach because it's already in their house. But it's worth getting a plunger or a drain snake for the job instead. It'll be a lot less money to buy a new plunger than to pay a plumber to repair or replace damaged pipes.

You can unclog an AC drain line for free if you already have these household ingredients: water, vinegar, and rags. Alternatively, if you’d rather not deal with the mess, you can hire a pro to clear your drain line. If you go that route, an HVAC service call costs between $100 and $250.
