"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

To unclog a plumbing vent, you first need to locate it. Look at your home's roofline. The plumbing vent will be a vertical pipe sticking straight up from the roof. Since this pipe runs all the way to the main drain underneath your house, you should also be able to find it in the attic.

While you don’t have to run out and immediately buy a new toilet at the first sign of a clog, if the toilet keeps clogging because it’s a low-flow or poorly designed model, a new toilet may be the way to go. If your toilet keeps clogging, you can try using less toilet paper, adjusting the fill valve, checking the toilet vent pipe on the roof, and using a toilet auger to make sure nothing is stuck in the pipe or trap.

Water leaking through your basement floor is a good sign of a clogged drain, but another sign of a clogged basement floor drain can include unpleasant odors coming from the drain. Also, hearing gurgling noises when water drains from the basement or having other plumbing fixtures (like toilets or other drains) backing up is a good indicator.

You should not attempt to snake your sewer yourself. Accessing and snaking your sewer requires heavy-duty equipment, and while renting is possible, misusing it can damage your sewer main and leave you with very expensive repair costs, not to mention potential environmental issues and severe water damage. Accessing your sewer also exposes you to hazardous sewer gasses, and failing to seal the sewer properly after work can be very dangerous. It’s always best to hire a professional sewer cleaner near you to handle this type of work.

Yes, pop-up drains commonly get clogged with hair, soap scum, and toothpaste. It is important to know how to properly clean the drain or get professional help to ensure it remains clear and can drain water effectively.
