"Jason responded quickly to a rather pressing issue I had with a collapsed sewer line from my townhouse. He stayed late the first day to ensure I had service and also affected repairs to a downstairs toilet which had never been properly installed."

"Great people and honest. I appreciate this all the more lately after having to deal with two separate plumbing companies who were not nearly as honest. They mounted a toilet, roughed in two drains and some other work for $306. I was quoted by another company that this job would cost almost $2000.   Honest people need to be rewarded and it is hard to find them these days. Thank you! Thanks again for helping me out:)"

French Drains FAQs, answered by experts

Start by unscrewing the overflow valve, which is located on the wall of your tub between the floor drain and the tub spout. Gently insert a plumbing snake down into the pipe, move it back and forth, and pull it out. Remove any hair, debris, and soap scum that comes out with it. Repeat the process until the snake comes out clean, and then reinstall the cap on your overflow valve.

Liquid drain cleaners are harsh chemicals that can erode your pipes. To treat a slow drain or for preventative maintenance, pour hot water down the drain to break up gunk and help move it along. Make sure the water isn’t boiling hot (keep it under 140 degrees Fahrenheit) if you have plastic pipes. However, you’ll need to pull the clog out for bigger backups. 

You can often unclog a garbage disposal in less than 10 minutes, though sometimes you might need longer if you’re unsure what’s causing the clog. For minor clogs, consider plunging the drain, flushing the drain with baking soda and vinegar, or using an Allen wrench to free the clog. If the clog is more severe, contact a local plumber.

Vinegar is better for an AC drain line because it’s less corrosive and won’t damage the pipes. It’s also a safer and easier product to use. Bleach should not be used on your AC drain line because it can corrode your pipes and harm the evaporator coil in your air conditioner.

It is okay to use a drain auger on a toilet, just make sure you are using the correct tip size. The auger is a plumbing snake with a protective sleeve to protect the porcelain toilet bowl from getting scratched. Using too large of an auger can cause the snake to loop back and damage the inside of the drain and plumbing.
