"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

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.

Bleach isn’t likely to help unclog a sewer line. Bleach isn’t useful in this situation because it won’t dissolve the grime and debris in the clog. Instead, you want to use ingredients that will have a chemical reaction to clear out the buildup, like vinegar or salt and baking soda.

Homeowners insurance usually doesn’t cover sewer backups because it’s typically an avoidable problem with proper maintenance. The only exception would be if the backup is occurring because of local flooding and only if your city uses a combined drainage system for stormwater and sewage. If that’s the case, your policy should cover any resulting damage.

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.

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
