"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!"

"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."

"We've been working with Mike Counsil for over 8 years - clogged drains, water heater, new toilets, and most recently a sewer re-pipe. 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

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.

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.

It is generally not recommended to pour hot or boiling water down a drain to unfreeze pipes due to significant risks. In some cases, the sudden temperature change can cause more ice buildup or produce steam, which increases pressure and could cause the pipe to burst, leading to costly damage and potential burn injuries. While hot water might help with a partially frozen drainpipe, it is unlikely to thaw a completely blocked water pipe further down the system. Additionally, boiling water can damage plastic pipes over time. Safer and more effective methods include using a space heater near the frozen section or applying hot towels directly to the pipe.

Bleach isn’t likely to help unclog a sewer line. Bleach isn’t useful in this situation because it won’t dissolve the grime and debris in the clog. Instead, you want to use ingredients that will have a chemical reaction to clear out the buildup, like vinegar or salt and baking soda.

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.
