"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."

"I can’t recommend Fluid Dynamics enough! I had a completely clogged sink drain that was driving me crazy, and they came to the rescue quickly and professionally. Not only did they unclog it in no time, but they also explained what caused the problem and gave me tips to help prevent it in the future. They were punctual, polite, and left everything spotless when the job was done. It’s so refreshing to work with someone who takes pride in their work and truly cares about their customers. If you need a reliable plumber who goes above and beyond, look no further—Fluid Dynamics is the one to call!"

"We called Plumbtree Plumbing and Rooter to our mothers home to deal with a clogged kitchen drain. Josh arrived on time and put his shoe covers and mask on before entering our mothers home. Josh seemed to have all the equipment he would possibly need as our kitchen drain proved to be rater stubborn but after about a half hour of hard work he announced that the drain would work. Josh cleaned up after the work was done and sanitized all the surfaces that he had touched!! We will definitely be recommending Josh and Plumbtree Plumbing to our friends and family for their plumbing needs!"

"Gustavo from Escamilla plumbing is a pro thru and thru. I gave him a tough job that I wanted to tackle but didn't have the necessary tools or time to tackle. I had him relocate the water heater lines and install a tankless water heater, remove steel pipes and redo drain lines. The kicker for the water lines was access next to a furnace and new gas lines that needed to be run due to insufficient gas supply. During the project we found micky mouse water line taps that needed to be removed and the house water shutoff valve that failed to closed completely. Lots of unexpected work but he gave decent quotes to complete the job. He is quick, doesn't cut corners, and gets the job done. I wholeheartedly recommend him for project a homeowner wouldn't touch or doesn't have time to do."

"Wilmar Plumbing was very responsive and empathetic towards my situation. They had to fix a problem caused by the previous plumber who installed my shower/tub drain incorrectly. I couldn't shower due to the leak. They treated my case like the emergency it was and Wilmar and his team showed up first thing. They fixed it diligently. They were so good, I hired them to install new bathroom sinks. These guys are great!"

"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 questions, answered by experts

There are many things that could cause your basement floor drain to back up. One significant cause of a drainage backup is flushing non-flushable items, such as wipes, paper towels, and facial tissue. Other causes of a backed-up basement floor drain include tree roots impeding the drain pipe or an accumulation of hair, oil, and grease. 

Start by unscrewing the overflow valve, which is located on the wall of your tub between the floor drain and the tub spout. Gently insert a plumbing snake down into the pipe, move it back and forth, and pull it out. Remove any hair, debris, and soap scum that comes out with it. Repeat the process until the snake comes out clean, and then reinstall the cap on your overflow valve.

To unclog the drain pipe, remove the machine's drain hose from the pipe or sink drain, being careful to contain any water in it. Next, use a plunger for sink drains or a plumbing snake for a wall drain. Test the repair by pouring a small amount of water into the pipe before trying it with a laundry load.

Common causes include hair buildup, soap residue, food particles, and foreign objects. Older pipes can also contribute by facilitating buildup more easily.

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.
