"The previous owner of our property used his French drain installation as a selling point, but shortly after we moved in we found water in the basement after a storm. It turned out that the "French drains" were a trench at the edges of the basement and a sump pump. The drains were not piped to the sump pump. We had Arid install real French drains with pipe to the sump pump well. Thus was in 2005 and we have not had any water in the basement since. Pat explained the job well and his team performed it quickly. They cleaned up well afterwards. The pump finally gave out last night (after almost 12 years). Arid is going to install new one on Friday."

"Arrived on time. Performed work in a professional manner. When first attempt to clear clog showed that clog was not in sink drain line, quickly relocated to crawl space where 1.25 inch copper sink drain line connected to the 2 inch copper drain line that connects to 6 inch cast iron drain line. Worked diligently until clog was removed and proven by sink not backing up and, after flowing hot water, by the 2 inch drain line feeling hot at the point of connection to the 6 inch cast iron pipe and by the sound of the water entering the 6 inch pipe. Checked for leaking sink p trap connections and for the 2 inch plug that was removed to access the 2 inch copper line. Cleaned up work areas."

"Situation resolved!!!! This started off as a little bit of water in the corner of the basement but escalated very quickly with the snow melt. Sean was here the same day I called to assess the situation and began work shortly after. They had to chop up the entire perimeter of the basement floor to install the french drains. This is definitely messy work and they never left a mess behind. All the guys were great and the work was well done and in a very timely manor. HUGE amount of stress has been lifted and thank you to Century Masonry and Waterproofing for making the process relatively painless."

French Drains FAQs, answered by experts

Regardless of the drain cleaner type you choose to use, they all work through chemical reactions that create heat. Thanks to the heat, the clogged hair begins to dissolve until it is able to be flushed away. To avoid clogs in your drain due to hair, use hair catchers and empty them out after every shower.

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. 

A bit of water in the bowl can help unclog a toilet, especially if you're using a plunger. However, if the bowl is full to the brim, you'll need to strap on gloves and remove some of the wastewater in a cup or container so it doesn't overflow when you try to unblock the pipe. If you're concerned about it filling further, manually close the flapper in the toilet tank or turn off the water supply to the toilet.

Flushing the toilet only to realize it’s clogged can cause anxiety. To avoid a clogged toilet, use less toilet paper. If you notice that the toilet is flushing and refilling slower than usual, you can use a plunger to clear clogs in the S-trap. If that doesn’t work, call a plumber to check your system and possibly clear the drain lines.

It takes hair about two years to dissolve on its own in the drain without the use of any tool or help. Fortunately, using a drain snake, plunger, or any of the actions mentioned above to dissolve the hair will help get rid of the clog in as little as 15 minutes.
