"I finally got to build my dream garage to store all my tools and have a cool hangout on Friday nights with the boys n a couple coors. Chris came and did everything from the bathroom and the heating system. I will definitely be calling him back to add a mini split in the future. He was professional, punctual and clean. Very knowledgeable you can tell he cares about his clients."

"I hired Mike to help me with a couple little things around the house (broken toilet, issue with the hot water in the kitchen) and he was great. He tried to talk me through some things over the phone first to save me the time and money but when I explained that I'm useless with this stuff he agreed to meet the next day. He fixed things immediately and charged me very reasonably. I live in a condex and later my neighbor was having major plumbing issues that related to the combined plumbing. I called Mike back and again came out promptly and worked with both of us to get the problem resolved. As a single mom I rely on quality and honest workmanship and I have been very pleased with Gotme Under Pressure and an planning to use him again when my new bathroom faucets come in."

Sewer Cleaning FAQs, answered by experts

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

If you’re wondering whether rats can come up the toilet, the unfortunate answer is yes, it’s possible, though it’s extremely rare. These rodents are excellent swimmers and can travel through sewer pipes in search of food, and they may follow plumbing lines leading to your home if they’re drawn by the scent of scraps and waste. The toilet’s U-bend holds a small pocket of air, which can help a rat catch its breath before making its final push into your bathroom. While more common in cities with larger rat populations, this can happen anywhere with connected sewer systems; sealing entry points and keeping drains clean can help reduce the risk.

Regardless of the drain cleaner type you choose to use, they all work through chemical reactions that create heat. Thanks to the heat, the clogged hair begins to dissolve until it is able to be flushed away. To avoid clogs in your drain due to hair, use hair catchers and empty them out after every shower.

While some chemical drain cleaners with hydrochloric acid can dissolve hair, this method is not recommended as it can also destroy your plumbing pipes. A common DIY alternative is using baking soda and vinegar, which can help break down the clog but will not actually dissolve the hair. The best and safest method for clearing a hair clog is to remove it manually. You can use a drain snake, a straightened wire hanger with pliers to fish out the clog, or have a plumber use a professional auger for more severe blockages.

If you want to avoid using a snake to unclog a drain, or if you don’t have one, try vinegar and baking soda. Pour 1 cup of baking soda down the drain, followed by 1 cup of white vinegar. Wait for 15 minutes, and then run hot water (but not boiling water) down the drain to see if the clog is clear. Repeat multiple times as needed.
