"I called Matt on a Sunday in need of a plumber for Monday and he rearranged his schedule to help us out so we could move forward with our bathroom renovation after listening to our situation. He came over and removed our old cast iron tub which was just a bonus because I was going to keep it even though I didn’t want to. He also put in a new shower valve and fixtures, tub drain, sink faucet, and toilet. It was a big job and he did it effortlessly and I couldn’t believe he was at our house in less than 24 hours of calling him. His work was impeccable, he has fair pricing, he was clean and a pleasure to have in our home. He was also a wonderful mentor to his apprentice who he walked him through everything they were doing. I highly recommend Ferris Plumbing and will definitely call him for our next renovation project."

French Drains FAQs, answered by experts

If you're dealing with a clogged sink drain, you may be able to avoid removing the drain by using a plunger to dislodge the clog. While we associate plungers with toilets, they can do the same job with your sink drain. Be gentle, though, as forceful movements can push clogs further into your plumbing system and make them more difficult to remove. Additionally, make sure you’re using a sink plunger—with a flat bottom—and not a toilet plunger—which has a smaller bottom protruding from the larger flat piece.

Clogged pipes are one of the top signs your water heater is about to fail. Potential symptoms of excess sediment buildup include not enough hot water, leaks, unusual noises, low water pressure, and discoloration or odors in the water.

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.

While some chemical drain cleaners with hydrochloric acid can dissolve hair, this method is not recommended as it can also destroy your plumbing pipes. A common DIY alternative is using baking soda and vinegar, which can help break down the clog but will not actually dissolve the hair. The best and safest method for clearing a hair clog is to remove it manually. You can use a drain snake, a straightened wire hanger with pliers to fish out the clog, or have a plumber use a professional auger for more severe blockages.

If you’re not using a septic system, problems with your home’s plumbing won’t cause this—it’s a city problem. A large blockage in the municipal sewage lines may cause those lines to back up into your home. This is extremely unpleasant and can be a serious health risk due to bacteria and other contaminants. If this occurs, call a pro (or your city) immediately.
