"Jake showed up on time (after calling to confirm his arrival time) and went about fixing our leaking drain pipe and feed lines under our kitchen sink. He was personable, professional, and did the job quickly and perfectly. We'll be sure to use Moto-Rooter again should we have any other plumbing problems. Top-notch work!"

"Blake Excavation was recommended and we are ever so grateful! Our Septic Drainfield had failed after 42 years and we were in need of urgent help. Despite delays courtesy of an understaffed DEQ Jason kept us informed and was onsite the minute the permit was approved. The crew showed up on Friday and worked through the weekend to get us back online. They were courteous and caring and we are ever so grateful!"

"I contacted Purist on Friday to replace a tankless water heater that was beginning to leak. Over the weekend they lined up all of the necessary equipment and parts (even got a phone call on Sunday to give me an update) and were on site Monday morning. Cristian is very precise in everything he does and is absolutely fantastic about leaving the project site clean and neat. Price was good, with no unexpected surprises. They are definitely on my phone as the go to plumber"

French Drains FAQs, answered by experts

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.

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.

Bleach isn’t likely to help unclog a sewer line. Bleach isn’t useful in this situation because it won’t dissolve the grime and debris in the clog. Instead, you want to use ingredients that will have a chemical reaction to clear out the buildup, like vinegar or salt and baking soda.

Professional plumbers use many high-grade chemicals to unclog drains. Many use hydrochloric acid, known as muriatic acid, when it comes to extreme blockages. 

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.
