"Cornelio set an appointment the next day when I messaged to fix two faucets in our bathroom. He made a free inspection, gave us a very reasonable quote, and offered to work on the fix the same day. He explained to us how the cartridge in the faucets are clean and unclogged, but the faucet body from the cheap brand is clogged and not serviceable. He recommended replacement faucets that should last longer and serviceable. We appreciated his honesty and would ask for his service again!"

"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!"

Yes, they may be more expensive than other companies, but with Mike Counsil you get what you pay for - quality work. A big shout out to Rudy and the whole team - they are hardworking, reliable and courteous."

Drain Cleaning questions, answered by experts

Yes, chemical drain cleaners contain sulfuric acid and hydrochloric acid, both of which are not only dangerous to your health but also extremely caustic. Drain cleaners will corrode your pipes and could lead to destroyed drain lines, especially if the chemicals interact with the piping for long periods. Unfortunately, this extended interaction is likely if you’re dealing with a clog, as the drain cleaner will have just as much trouble as water does moving through your plumbing system.

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. 

In some cases, operating a snake can damage your drain and pipes. This depends on the overall condition of your pipes and how gently you operate the auger. For instance, older galvanized pipes covered in zinc are susceptible to scratches when using a drain snake. Additionally, it’s common for newbies to apply too much force when extending the snake, leading to scratches and related damage. You can also crack the porcelain with an electric auger if you’re snaking a toilet drain. If you’re using a manual snake or auger, the risk is minimal.

Your sewer line can get grimy quickly. To prevent sludge buildup in your sewer line, pour a mixture of 1/3 cup of vinegar and 1/3 cup of baking soda down each drain in your home once a month. After about 30 minutes, flush the drain with hot water.

Some plumbers recommend 3/4 cup of bleach instead to clean any germs and bacteria that may build up in your sewer line. But this won’t break down any active clogs, and it cannot be combined with vinegar, as the mixture will create a toxic, hazardous gas.

Yes, short hair can clog a drain. While you might be tempted to blame the long-haired people living with you for a clogged drain, hair—no matter the length—can combine with soap scum and leftover shampoo to create a perfect storm of sticky mess that can cause your drain to slow down.
