Stephen was helpful with pictures and explanations and cleaned up after he was done. I would recommend Mr. Rooter and Stephen to anyone."

Drain Cleaning FAQs, answered by experts

Your garbage disposal is not draining because it might have a clog due to food waste, a foreign object, grease, oil, fat, or it may have a broken motor. When water doesn't flush out of the disposal, that's a key sign that your disposal has a clog or needs repair. 

Yes, you can use vinegar to unclog a dishwasher. To do so, combine 4 tablespoons of white vinegar with 4 tablespoons of baking soda and pour the mixture down your dishwasher’s drain. Let it sit for 15 minutes, then pour a cup of hot water down the drain to flush everything out. Finally, run a rinse cycle on your dishwasher to see if the clog is gone.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

If you leave liquid drain cleaner for too long, it will start breaking down your drainpipes. The chemicals in these cleaners can cause cracks, corrosion, and leaks in your pipes. They can also damage plumbing fixtures and even cause environmental damage if left too long without rinsing away.

Most blockages can be cleared in 1-3 hours, but severe issues may take longer.
