"When we finally determined that our problem was clog in the drain pipe that was under a slab we were very concerned. I posted my problem on Home Advisor and got an immediate response from this company. Charlie was here on a Saturday within a couple of hours! He snaked about 50 ft. and the problem was solved within minutes! So grateful for solving this problem the weekend before Christmas! Price was reasonable for a weekend. I would recommend him for drain problems!"

French Drains FAQs, answered by experts

If methods like hot water or a plunger don’t work on your clogged drain, you can snake your drain to dislodge the plug. This can be a messy process, taking some physical effort and additional time over the other drain-clearing options. You can purchase a drain snake at a hardware store and choose from handheld options or those attached to a drill. Just work slowly, and be ready to call a plumber if you’re unable to reach the clog from your drain or P-trap.

Professional plumbers use many high-grade chemicals to unclog drains. Many use hydrochloric acid, known as muriatic acid, when it comes to extreme blockages. 

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.

Clearing typically takes 1-2 hours, depending on the blockage size and location.

To prevent drain clogs, perform regular maintenance and cleaning. Avoid disposing of substances like grease or coffee grounds down the sink. Additionally, installing and routinely using drain strainers can help catch debris and prevent blockages from forming.
