"Water Field was awesome. This is an old house with many challenges along the way; in other words - this was not a simple hot water heater install. Even with all the challenges, the work was done professionally, and cleanly. I will certainly use Water Field again without hesitation. Quality work, at a very reasonable price!!"

"BFMD is the best sewer line cleaning service I have ever used. Several other contractors insisted that I needed a new sewer line and quoted very high prices. BFMD determined this was not necessary and was able to clear my line completely. Great job, great service, great professionalism, and great honesty."

"Excellent! Sterling was prompt, courteous, and professional in the way he went about the job, explaining each step and telling me up front what the cost of the effort would be. He cleaned the clog and left no mess whatsoever. I would highly recommend his business and would seek his help again for another plumbing problem."

Sewer Cleaning FAQs, answered by experts

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.

Never pour used motor oil down the drain. Doing so can have serious environmental consequences, including contaminating groundwater, endangering animals, and killing vegetation. It can also clog your pipes, causing backups in your plumbing or the wastewater treatment plant. In most places, pouring motor oil down the drain is illegal, whether you do it in your home or a storm drain.

It can take anywhere from one month to a couple of years for tree roots to grow back in sewer lines. Tree roots can cause extreme havoc on your sewer lines, potentially cracking them and causing untreated wastewater to make its way into the groundwater. Have a landscaping pro remove trees and roots before installing your system, or call a pro to do it retroactively as soon as you can.

A clogged sewer line is not typically covered by homeowner’s insurance, though some sewer line issues are covered. For instance, damage related to a fallen tree is usually covered. Though sewer line replacement is not covered in a standard insurance policy, some companies offer add-ons for this purpose. Read the fine print before spending your own money.

To prevent drain clogs, perform regular maintenance and cleaning. Avoid disposing of substances like grease or coffee grounds down the sink. Additionally, installing and routinely using drain strainers can help catch debris and prevent blockages from forming.
