"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

No, it is not advisable to spray pesticides down the drain in your home. Most drinking water and wastewater treatment systems are not properly equipped to remove pesticides. Should pesticides infiltrate waterways, they can cause harm to plants, fish, or other living things. In most areas, pouring pesticides down the drain is illegal due to the potential harm it causes. 

It is generally not recommended to pour hot or boiling water down a drain to unfreeze pipes due to significant risks. In some cases, the sudden temperature change can cause more ice buildup or produce steam, which increases pressure and could cause the pipe to burst, leading to costly damage and potential burn injuries. While hot water might help with a partially frozen drainpipe, it is unlikely to thaw a completely blocked water pipe further down the system. Additionally, boiling water can damage plastic pipes over time. Safer and more effective methods include using a space heater near the frozen section or applying hot towels directly to the pipe.

A plumber can get to the bottom of your smelly drain and clean it with specialized jets, hoses, and drain-safe cleaning solutions. It is also smart to call in a plumber if you suspect your drain smell is coming from a stubborn clog or even a leaky pipe.

There are several common signs that your main sewer line may be clogged. Key indicators include multiple fixtures in your home draining slowly, gurgling sounds coming from drains or toilets, and water backing up into showers, sinks, or toilets. You might also notice water backing up from the plumbing system's drain cleanout, water in your basement drain, or unexplained wet patches on your lawn. Foul odors, such as the smell of raw sewage or rotten eggs, are another common symptom. The most reliable way to confirm a main sewer line clog is to hire a professional plumber to perform a camera inspection.

If you have a sink stopper, it can feel more challenging to clean the drain without removing it, but here are a few simple steps:

  • Pour ½ cup baking soda into the drain using a funnel

  • Pour 1 ½ cups vinegar into the drain

  • Close the sink stopper for 15–20 minutes

  • Open the drain

  • Pour 2 cups of boiling water down the drain (be cautious as boiling water can damage some types of pipes)

If the drain isn’t unclogged, repeat the process.
