"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 want to say a big thank you to Plumbtree plumbing and rooter. I had a drain backup and called another plumbing company, who came out and cleared my drain, but 2 days later I was back to square one. Frustrated, to say the least. A friend of mine told me about plumbtree plumbing and rooter and their positive experience with them. So I called. I was impressed to say the least. When Josh, the plumbing technician came to the door, he was very friendly and very courteous. He only entered my home after putting on shoe covering to protect my floors. He assessed the situation and suggested that after he clears the drain that he should camera the line to find out why the backup reacurred. After clearing the drain he camera the line and found that I had a collapse mainline pipe. He was able to uncover the pipeline and repair it. Such a great relief to get to the bottom of my problem and have it repaired in 1 day. I definitely got what I paid for the first time around. Cheap is not always the way to go with plumbing issues. Plumbtree plumbing and rooter was well worth the money. Honest, friendly and caring. They went the extra mile for me. I would highly recommend these guys"

"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."

"What started as a simple toilet replacement encountered a couple curve balls because the age of the existing home. Wilmar Plumbing marched right through and solved the problems, even though they were not all plumbing related. And they did these "extras" at no additional cost! They arranged a date quickly, were responsive to my calls, arrived on time and cleaned up the mess in an quick and efficient manner. Wilmar Plumbing came in a large van that was fully equipped with parts, no running off to Home Depot. I already have another project in mind and won't hesitate to bring them back. Thank you Wilmar and team!"

"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

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.

Yes, frozen pipes can cause a toilet to stop working correctly. If the pipes are frozen, water cannot flow, which can lead to two main problems. First, the supply line to the toilet tank may be frozen, which prevents the tank from refilling with water after you flush. Second, the drain pipe itself can freeze, blocking water from flushing away. As a temporary solution for a non-refilling tank, you can manually add water, but this is not a long-term fix. To clear a frozen drain pipe, you can try pouring warm water into the toilet bowl or tank and then flushing, as the warm water may help thaw the ice blockage. Ultimately, the best course of action is to unfreeze the affected pipes to restore your toilet to full functionality.

If your dishwasher keeps filling with water at the bottom but doesn’t fill into the sink, the issue is likely due to a blockage within the dishwasher or drain. Regularly clean your dishwasher filter basket to ensure it’s not clogged with food, and run a vinegar rinse periodically if you have hard water to remove limescale buildup.

To prevent drain clogs, perform regular maintenance and cleaning. Avoid disposing of substances like grease or coffee grounds down the sink. Additionally, installing and routinely using drain strainers can help catch debris and prevent blockages from forming.

Most commercial liquid drain cleaners work in 15 to 30 minutes. Consult the label on the bottle for additional instructions or time suggestions to prevent damage to your drainpipes. Alternative solutions such as baking soda, salt, white vinegar, and/or boiling water can take longer since they are less harsh than liquid drain cleaners.
