"Everything about this repair job was wonderful - from Brad giving us the bid (and explaining exactly what would be done), to Will and Ree (sp?) doing the excellent work. Everyone was courteous, professional and left everything spotless. And the cost was surprisingly lower than I thought it would be."

French Drains FAQs, answered by experts

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.

Anything you drop down your sink runs the risk of damaging and clogging your pipes. Hair, bits of food, and other debris can catch on the item and build up over time, causing a clog. Even if it’s not valuable, it’s definitely worth trying to retrieve the item, or at the very least, asking a pro for specific advice.

In most areas, drain cleaning professionals don’t technically need a license, as they aren’t altering your plumbing system in any way. However, we recommend hiring a drain cleaning professional with a plumbing license and certification. Certified plumbers are more likely to provide professional solutions to drain clogs without damaging your system. They’ll also have the diagnostic tools and experience necessary to remove the clog entirely rather than providing a temporary solution, as a handyperson might. Use Angi’s state licensing tool to check your plumber’s professional licenses before hiring.

No, you should avoid using liquid drain cleaners. These chemicals, often packed with sulfuric or hydrochloric acid, can wreak havoc on your pipes, causing erosion and potential leaks. They’re also dangerous to your health. If you’re dealing with a stubborn clog, manual removal or a professional plumber is your best bet. Chemical drain cleaners can often make things worse, especially if the clog stays put and the chemicals linger in your pipes.

If your dishwasher keeps filling with water at the bottom but doesn’t fill into the sink, the issue is likely due to a blockage within the dishwasher or drain. Regularly clean your dishwasher filter basket to ensure it’s not clogged with food, and run a vinegar rinse periodically if you have hard water to remove limescale buildup.
