Sewer Cleaning questions, answered by experts

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.

It might be possible to dissolve hair caught in a drain, but it’s usually not a good way to go about clearing the clog. Some sources mention that baking soda and vinegar can do the trick, but this won’t actually dissolve the hair. The hydrochloric acid in drain cleaners can dissolve the hair over time, but it will much more quickly destroy your plumbing pipes and leave you with bigger issues. The best way to remove hair is to do it manually with a drain snake or to have a plumber use an auger to pull clogs out.

Black Friday, also known as the day after Thanksgiving, is one of the busiest days of the year for plumbers. Plumbing pros receive many service requests for clogged drains, garbage disposal issues, and clogged sewer lines. Don’t hesitate to call a plumber on Black Friday if you experience emergency plumbing problems.

Food grease, soap buildup, paper products, and tree roots often cause serious clogs.

There are a few things that can happen to your sewer system if you don’t fix it. These include rainwater entering it and causing rust and corrosion, dirt and debris leading to blockages, small animals getting stuck inside and clogging your sewer line or entering your home, and shortening the sewer system’s life span. 

Without a cap, nothing prevents toxic and non-toxic gasses like methane and hydrogen sulfide from slowly escaping your sewer system and entering your home and the surrounding atmosphere, resulting in a foul sewer odor throughout your house.
