"As a small business owner, I strongly caution others against this HVAC/R company. In over 10 years, they?ve been the least trustworthy and poorest performing contractor I?ve worked with. We experienced repeated service issues, a 25% rate hike without notice, ignored emails, and unreturned quote requests. Worse, we were billed for work that wasn?t done?confirmed twice, including by a third-party inspection with photos. Even when confronted, they deflected and delayed for months. We had to hire another company. They also mis-sized a walk-in freezer due to bad measurements and blamed their supplier. When shown proof it was undersized, they argued with no solution. They later mismeasured again on a replacement bid. Their attitude throughout was defensive, unprofessional, and dismissive. If something goes wrong?and it likely will?they will not stand behind their work. Save yourself the frustration and look elsewhere."

Sewer Cleaning questions, answered by experts

If you’ll be digging up your floor to get access to your pipes when putting in a sewer backflow preventer, this would also be a good time to take care of any other plumbing issues or renovations. For example, you could install additional pipes for a basement bathroom. Since the floor will be sealed over with concrete when you’re done, now’s a good time to take care of those bigger tasks.

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.

Some signs that your main sewer line is clogged are easy to spot, like when water backs up into your showers, sinks, and toilets for no apparent reason. However, some indicators are more subtle. The most common signs that you may have a clogged sewer main include:

  • Gurgling sounds coming from drains or toilet

  • Water in your basement drain or in the lawn

  • Smell of raw sewage throughout your home

  • Other found odors like rotten eggs around your home

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