The cost to repair a main sewer line clog is about $3,110 on average. The average cost range is $1,310 to $4,950, but it can go as low as $215 and as high as $9,300 or more. The cost factors for this repair include the severity of the clog, pipe accessibility, video inspection, removal method, permits, pipe material, labor rates in your area, and time of year. Repairs made from outside during the winter can be more difficult due to the frozen ground or during the spring if the ground is saturated from a lot of rain and snow melt.
Most commercial liquid drain cleaners work in 15 to 30 minutes. Consult the label on the bottle for additional instructions or time suggestions to prevent damage to your drainpipes. Alternative solutions such as baking soda, salt, white vinegar, and/or boiling water can take longer since they are less harsh than liquid drain cleaners.
In most cases, drain cleaners will not clear a clogged sewer line, and they’re likely to damage your plumbing. Sewer lines are several inches wide, meaning any material that clogs it will need to be large. Drain cleaner can work on small clogs, but it usually won’t clear a larger one in a sewer main. Drain cleaners can also easily damage and corrode your plumbing with prolonged contact, and a clog will keep the cleaner in contact with the pipes for an extended period. Hire a professional sewer cleaner instead for a safe fix.
Snaking a toilet is similar to clearing sinks and bathtubs, but there are unique circumstances where you’d have to drain, disassemble, and remove the toilet to fix the clog. For stubborn clogs in the toilet trap, a toilet auger—designed with a shorter cable and a protective plastic encasing—can navigate the tight bends and clear the clog without risking damage to the porcelain.
Even with a high-resolution camera, what you're looking at on the screen may not be recognizable to the untrained eye. Your plumber should be willing to walk you through the video and explain what they found. With high-res images, bright lighting, and self-leveling technology, you should get clear, steady views of the pipes that make up your plumbing system.
