"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

You can unclog a double kitchen sink by plunging the side with the garbage disposal. Cover the drain hole on the other side first to avoid creating a mess. Plunge up and down until the water starts to drain. You can also pour in baking soda and vinegar to try and dissolve a clog. 

Never pour used motor oil down the drain. Doing so can have serious environmental consequences, including contaminating groundwater, endangering animals, and killing vegetation. It can also clog your pipes, causing backups in your plumbing or the wastewater treatment plant. In most places, pouring motor oil down the drain is illegal, whether you do it in your home or a storm drain.

Some homeowners use additives every month to help septic system performance, but according to the U.S. Environmental Protection Agency, the effectiveness of septic system and leach field additives is unknown. Further, additives made with organic solvents or alkali chemicals can actually be harmful to the necessary bacteria in a septic system.

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.
