"Did a great job, thorough, good cleanup and were careful not to make a mess on our main floor. Came back afterwards to flash the french drain to see if that helped reduce our radon levels. Really nice guys, would highly recommend."

"Arrived on time. Performed work in a professional manner. When first attempt to clear clog showed that clog was not in sink drain line, quickly relocated to crawl space where 1.25 inch copper sink drain line connected to the 2 inch copper drain line that connects to 6 inch cast iron drain line. Worked diligently until clog was removed and proven by sink not backing up and, after flowing hot water, by the 2 inch drain line feeling hot at the point of connection to the 6 inch cast iron pipe and by the sound of the water entering the 6 inch pipe. Checked for leaking sink p trap connections and for the 2 inch plug that was removed to access the 2 inch copper line. Cleaned up work areas."

"We had started to get water coming in from the foundation of our basement. Sean had come to our home to give us our best option and estimate of what work they would end up doing. Overall it seemed like the best choice, and sure enough, it was. We had french indoor drains installed in our basement, along with an updated sump pump with a battery backup incase of power outages. Ever since this was completed, we've had no issues, and our basement is fully dry. It only took a few days to complete, and they did a great overall job!"

French Drains FAQs, answered by experts

It is okay to use a drain auger on a toilet, just make sure you are using the correct tip size. The auger is a plumbing snake with a protective sleeve to protect the porcelain toilet bowl from getting scratched. Using too large of an auger can cause the snake to loop back and damage the inside of the drain and plumbing.

Your sewer line can get grimy quickly. To prevent sludge buildup in your sewer line, pour a mixture of 1/3 cup of vinegar and 1/3 cup of baking soda down each drain in your home once a month. After about 30 minutes, flush the drain with hot water.

Some plumbers recommend 3/4 cup of bleach instead to clean any germs and bacteria that may build up in your sewer line. But this won’t break down any active clogs, and it cannot be combined with vinegar, as the mixture will create a toxic, hazardous gas.

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.

While there is no specific “best” method to clear hair out of a drain, several options work well. Using a combination of baking soda and vinegar to dissolve the hair clog is a great and easy way to help clear the drain. Drain snakes are also effective for more severe clog buildups. 

The P-trap (or S-trap in older homes) under your shower is designed to prevent sewer gas from coming back up, so you shouldn’t normally experience foul odors coming from your shower drain. If you do, the vent stack that introduces air into your plumbing system may be clogged, or you may have a more severe sewer main blockage. In either case, hire a plumber to fix the issue for you.
