"It was after business hours when I call regarding a drain issue. The owner of the company came out himself to fix the problem. Upon arrival the issue was assessed and the fix was done efficiently and quick. This was incredible customer service considering the times we are in meaning the pandemic. Pricing was fair and I would recommend their services."

"My water heater was leaking and I needed it fixed asap because we had no hot water and I have small kids at home. Robert came, he saw the problem and fixed it fast and efficiently. He was professional and polite and the price was right. I will definitely call him again in the future. And have recommended him to family and friends. Thank you Drain Right Plumbing!!"

"We highly recommend Green Arrow Plumbing. Our clogged drain was due to the corroded cast iron drain pipes original from 1957 and Cornelio replaced them in short order. While he was here, he also fixed two toilet flushing problems which two handymen had been unable to do. Cornelio was very knowledgeable, his rates reasonable, and it was a pleasure to work with him."

"We thought we needed just our washer drain unclogged so we called the company that had fixed that before, you guys. Guys came out. Under the house they discovered rusted sewer lines. When we had our plumbing redone years ago, the company who did those did not remove the old lines. Those old lines were up against the sewer lines and were corroding our sewer lines. So we had to replace the sewer lines. A broken line just before the city line was discovered so we had to replace that too. Anyhow, we so appreciated the kind workers who smiled and waved at us. They worked around our water schedule as we have a physically disabled adult son we care for. They let us watch all the things they had to do. I took pictures and the guys were fine with that. My brand new front yard was not ruined by trenchless sewer system that went in. And my yard looks like we never had sewer lines done. It was amazing. Yes, we would recommend you to all."

Drain Cleaning FAQs, answered by experts

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.

Using less toilet paper is the easiest way to prevent future clogs. Also, avoid flushing sanitary products, thick paper towels, or hair down the toilet. If you’ve been using a brick in the tank to reduce the water used to flush the toilet, take it out immediately. Bricks will eventually fall apart and clog your toilet drain. Keeping your toilet lid closed also helps avoid future clogs.

Your clothes—and your washing machine—will send you a few signals if you’re overdue for cleaning your washing machine filter. If you notice a buildup of detergent residue on your clothes, your clothes don’t dry quickly or at all, or you’re noticing lint in the machine, it’s time to clean the filter. 

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

Anything from debris, rust, ice, and even poor installation can cause clogs in your plumbing vents. Some signs of a clog include slow drains, gurgling sounds in drains and toilets, and bad odors. The bad odors are the most concerning, as these can include methane and hydrogen sulfide. Contact a plumber to come take a look if you notice any of these signs.
