"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."

French Drains FAQs, answered by experts

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

An active cleaning agent and a drain snake is the best way to clean a main sewer line. You can purchase a regular or enzyme drain cleaner or make a DIY drain cleaner with baking soda. Use your chosen solution at least once a month or as needed to keep your sewer line clear. 

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.

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.

It’s possible to snake minor drain clogs yourself, provided they sit within a foot or two of the drain itself, but it’s usually best to hire a professional plumber regardless. Even experienced DIYers have a high chance of accidentally pushing the clog further into the drain using a drain snake or another tool, so hiring a plumber is the ideal course of action. A professional plumber can use camera equipment to locate and identify the clog, and remove the entire blockage to fix your issue permanently.
