"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."

French Drains FAQs, answered by experts

Coke and other sodas do clean a clogged drain, so this is one of those urban myths that has some truth behind it. Coke and similar sodas are caustic and will provide some cleaning power to your drains. However, the power of soda pales in comparison to dedicated cleaners or even baking soda.

Anything from debris, rust, ice, and even poor installation can cause clogs in your plumbing vents. Some signs of a clog include slow drains, gurgling sounds in drains and toilets, and bad odors. The bad odors are the most concerning, as these can include methane and hydrogen sulfide. Contact a plumber to come take a look if you notice any of these signs.

Baking soda and vinegar is a great solution for cleaning your sink drain; in fact, it’s our preferred method. Here’s how to unclog your drain with baking soda and vinegar: Pour in a half cup of baking soda, then 1 cup of white vinegar, and let the two bubble for 15 minutes. Then rinse out with boiling water. This method is much safer than using a chemical drain cleaner gel.

Air gaps get clogged by a few different means. Over time, food and grime can collect in the air gap, leading to a blockage. Mineral deposits from hard water are a common problem. Mineral buildup creates a film in the air gap and tubing, which can cause flow issues, as well as attract debris. Homeowners with hard water may want to remove mineral deposits regularly to keep the air gap clean and clear.

With a one-way cleanout, you can access your sewer line from one direction. Depending on the way it curves, a plumber can either access the side of the pipe that goes into your home or the side that goes to your yard. On the other hand, two-way cleanouts allow pros to access both sides of the sewer line, thanks to their dual-pipe design (they’re usually U-shaped).
