"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"

"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!"

Drain Cleaning questions, answered by experts

Grease buildup, tree roots, and foreign objects often cause blockages. Regular maintenance prevents major issues.

Air gaps get clogged by a few different means. Over time, food and grime can collect in the air gap, leading to a blockage. Mineral deposits from hard water are a common problem. Mineral buildup creates a film in the air gap and tubing, which can cause flow issues, as well as attract debris. Homeowners with hard water may want to remove mineral deposits regularly to keep the air gap clean and clear.

Costs vary by severity and access requirements. Typical pricing ranges from $100 to $350, increasing with complexity or for emergency services.

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.

If you're dealing with a clogged sink drain, you may be able to avoid removing the drain by using a plunger to dislodge the clog. While we associate plungers with toilets, they can do the same job with your sink drain. Be gentle, though, as forceful movements can push clogs further into your plumbing system and make them more difficult to remove. Additionally, make sure you’re using a sink plunger—with a flat bottom—and not a toilet plunger—which has a smaller bottom protruding from the larger flat piece.
