"I discovered my 10 year old water heater had developed a pretty good leak and called the branch located in Hudson, WI. Brian answered my call and he was very attentive to my needs, quoted me a better price than I was finding elsewhere, and was able to schedule an install in a very short time. I really appreciated his help and understanding of my situation. The install went great and my new water heater is functioning as it should! I'm definitely a repeat customer should the need arise!"

Sewer Cleaning questions, answered by experts

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.

You could be smelling sewer gas in your kitchen because of a dry P-trap, clogged vent pipe, or leaking plumbing seals. If you smell a rotten egg odor, check your sink’s P-trap and plumbing connections first. A clogged or damaged vent pipe can trap sewer gas and push it back into your kitchen through the plumbing pipes. Loose or deteriorated seals around drainpipes can also allow sewer gas to leak out. If you can’t find the source, call a local plumber for expert help.

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.

If your drain doesn’t have metal crosshairs or crossbars, you should use a tub drain extractor. These tools create a grip on the drain so you can turn it using a 1/2-inch ratchet drive, drain key, or wrench. Your drain may not have crosshairs if it's old and broken.

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.
