"We cannot express our gratitude enough for having Cornelio on the team during our comprehensive drain and sewer pipe replacement. In the midst of my recovery from a major accident that required two surgeries, we were hit with a severe plumbing issue. Every drain in our house was nearly unusable, among other challenges we encountered. Amidst all this chaos, Cornelio was a beacon of positivity. His professionalism was evident, but what stood out even more was his genuine care and concern. Every interaction was complemented with him inquiring about my well-being and eagerly awaiting updates on my recovery. Despite the project's unexpected complexities, Cornelio and his team ensured it was completed swiftly without compromising the quality of their work. If ever the need arises (though I hope we don't have any more plumbing issues for a long time!), I would hire him without a second thought. A heartfelt thank you to Cornelio and the team!"

"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!"

"What a savior! The drain stop in my bathtub broke off when I was trying to change the stop myself because the people who installed the bath tub used silicon based glue that made it impossible to unscrew the drain stop. Aaronâ s plumbing came and gave me two options, one that will cost me money and the other that would be way cheaper, if it works. They tried the cheaper option and did a great job at fixing the issue. Great and prompt service, very professional, and with intention to solve the customerâ s problem than to make money. Always recommended!"

"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."

"Jess and his crew did a great job recently repiping my house, both the water supply and drain lines. Jess is easy to work with and very responsive. His price was very reasonable. He came back promptly to fix some very minor issues I found (tiny leaks from the kitchen sink drain and from one of the outside faucets). Everything is fine now. The sprinklers in my backyard work better now because they're getting more pressure than they got from the very old galvanized pipes that were replaced. I'm happy to recommend him."

"The folks @ Mike Counsil have done work for us in the past, including the heater installation and unclogging/cleaning a backed up drain. Any time we've had work done by them, they are always right on time and very professional. They get the job done and clean up after they're finished to ensure there's no clean up for the customer. I highly recommend them for all of your plumbing needs."

Drain Cleaning questions, answered by experts

If you leave liquid drain cleaner for too long, it will start breaking down your drainpipes. The chemicals in these cleaners can cause cracks, corrosion, and leaks in your pipes. They can also damage plumbing fixtures and even cause environmental damage if left too long without rinsing away.

Yes, continuing to flush a clogged toilet is not likely to break up the clog. Instead, it will continue to put pressure on the clog while filling the bowl with more water, which can potentially cause the toilet to overflow—leading to an even bigger mess. Rather than repeatedly flushing, use a toilet plunger or plumber’s snake to dislodge the clog.

There are a couple of things you can do to help prevent your French drain grate from clogging. First, keep yard debris clear so it doesn’t wash into the drain and clog the grate. You can also install a screen or filter over the grate to prevent large pieces of debris from entering the access point.

Some experts estimate that descaling your cast iron pipes can extend their lifetime by upwards of 50 years, although there’s not a lot of research to prove it. But we do know that without proper maintenance, cast iron pipes can quickly rust—leading to more expensive issues like burst pipes or main line clogs.

You can unclog an AC drain line for free if you already have these household ingredients: water, vinegar, and rags. Alternatively, if you’d rather not deal with the mess, you can hire a pro to clear your drain line. If you go that route, an HVAC service call costs between $100 and $250.
