"Sterling was a great technician he worked extremely hard to clear my toilet drain. They really take pride in there work at this company and completely explained me the process and everything that was involved. I had roots clogging my toilet drain and Sterling was able to locate and remove the root issue and provide me with video evidence of just how clean the drain now is after the service. Very happy with the service provided."

"David & his team with Arcelio did an outstanding job! We needed it done on short notice & they rose to the occasion. And just before a weekend of heavy rains. So our basement went from waterfalls of leaks to dry as a bone, despite the heavy flooding outside. They took lots of pictures of the process so we could see all the work they did underground. They were reasonably priced & did the job done with good attention to detail & pleasing aesthetics with the river stone. We love that they guarantee their work. We're very grateful to have chosen Drainage & Erosion Solutions. We kept seeing their signs & trucks in the Del Ray, Alexandria neighborhood over the years & we can see why others chose them, also."

"Arrived when he said he would and quickly fixed my problem (clogged kitchen sink drain). He replaced pieces of drain pipe under my kitchen sink and snaked the drain line. Very personable person. I would hire him again."

French Drains FAQs, answered by experts

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.

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. 

The spin cycle on your washer should initiate draining, but if you still find leftover water in the washing machine tub, you may need to drain it manually. To manually drain a washing machine, you’ll need to turn off the power supply and locate the drain hose, filter, and pump. Open or disconnect these parts and let the water drain into a bucket.

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.

Even if the shower drain doesn’t seem clogged or dirty, plan to clean it out about once per month—or more frequently if you or your family shed a lot of hair. It’s a good practice to remove any hair from the drain on a daily basis, as hair can accumulate fast and cause clogs in no time. You may also want to have a plumber thoroughly clean the drains in your home once every six months.
