"Tony was very pleasant to work with. He accommodated my schedule, even with a big winter storm that had just rolled through. Tony and his team finished the project in about a day and a half and I couldn’t be more pleased! Not only was the job exactly what I needed/requested, but it was a very neat and clean job. His team respected my house and left the work area spotless. I will definitely call Tony if I ever need anything plumbing related."

Drain Cleaning FAQs, answered by experts

Avoid flushing non-degradable items, schedule regular inspections, and address minor clogs promptly.

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.

If the drain pump on your washing machine is continuously draining, it could be that the control board is damaged and requires repair, or there’s a clogged or kinked drain hose. If you can’t locate the problem, you’ll want to have a plumber or appliance repair expert come take a look.

You should inspect and clean your French drain at least once per year to keep it in good working order. Regular maintenance can help identify clogs, buildup, and damage before they become bigger problems, which increases the lifespan of your drain. The frequency with which a drain clogs can depend on factors like the amount of debris, the quality of the installation, and the type of filter used. If your drain accumulates a lot of sediment, it may require more frequent cleaning. It's also a good practice to check the access and exit points after heavy storms. If you notice reduced drainage or any signs of a clog, clean the drain as soon as possible.

A good option for opening up and cleaning a sink drain is to use a ¼ cup of baking soda and 1 cup of white vinegar, along with a rubber stopper to cover the drain while those materials work their magic. After about 15 minutes, you can flush the drain with hot water. In many cases, these materials can scrub out minor clogs and get the drain working properly again. If the issue persists, call in a plumber near you to get the problem permanently fixed.
