Clearing a clogged main sewer line typically costs between $200 and $600, with a national average of about $350 for standard snaking. Prices depend heavily on the severity of the blockage, the equipment required, and your location in Ninnescah Township, KS.
To clear a main sewer line clog, use an industrial-strength chemical main line opener (like Green Gobbler Main Line Opener or Instant Power Main Line Cleaner), or physically clear the blockage using a motorized drain auger (sewer snake). For severe blockages or tree roots, an auger is the most effective solution.
Water jetting is also the best solution for eliminating any grease or grime buildup that may be clinging to the pipe walls. This ensures that your sewer line will be thoroughly cleaned right down to the pipe walls to prevent future clogs.
For example, if a tree falls during a storm and cracks your sewer line, the resulting damage may be covered under your policy. Most routine issues, such as pipe deterioration, clogging, or gradual wear and tear, are considered the homeowner's responsibility and are not covered.
The longer the sewage is present in the home, the higher the risk of disease or permanent damage. Can the sewage make me sick? When you have a backup of sewage in your home, it is important to remember that sewage contains bacteria, fecal material, viruses, and other hazardous microorganisms that can cause illness.
Sewer lines generally last between 50 and 100 years, largely depending on the pipe material and environmental factors. Older homes with aging infrastructure may require repairs sooner.
If you're buying a residential gas-powered machine, look for a unit that delivers 2.5 to 2.9 GPM and is rated as close to 3,000 PSI as possible. This will provide very good cleaning and pulling power with a sewer jetter of up to 100 feet in length.
As the fall rains intensify and the seasons shift, one surprising tip is getting renewed attention: pouring vinegar down your drains to help prevent clogs.
The easiest, most reliable DIY method to clear a main sewer blockage is using a sewer bladder (drain flush bag). It attaches to your garden hose, expands inside the pipe, and uses high-pressure water to blast the clog downstream.

The "135-degree rule" in plumbing states that the total (aggregate) horizontal change in direction for a drainage pipe—specifically trap arms—cannot exceed 135 degrees between the P-trap and the vent. Exceeding 135 degrees (such as using three 45-degree bends or a 90 and two 45s) requires a cleanout because sharp turns hinder flow and cause clogs.
Standard, hand-powered drain-clearing tools aren't effective against a clog caused by tree roots that have entered an underground pipe. Contact a professional plumber to clear this type of blockage. And if the blockage is under the road or sidewalk, it may even be the city's responsibility to fix it, not yours.
Pouring salt down your drain at night is a popular DIY plumbing trick used for routine maintenance. The goal is to take advantage of the salt's coarse texture and natural moisture-absorbing properties.
To clear a main sewer line without a snake, locate your home’s outdoor sewer cleanout pipe. Use an expanding water bladder (flush bag) attached to a garden hose, or pour chemical treatments directly into the drain. For grease clogs, a mixture of boiling water, baking soda, and vinegar also works.
A straightforward yet effective approach to addressing a clogged drain pipe involves simply using hot water mixed with dish soap. This method, ideal for tackling minor blockages, leverages the degreasing power of dish soap combined with the force of hot water to dislodge and dissolve clog-causing residue.
If more than one drain is slow moving, gurgling, smells bad or has water backing up, you most likely have a main sewer clog.
Baking Soda, Vinegar, and Water Pressure
Mix baking soda and vinegar in the ratio of 1:2 and add the mixture in 60 gallons of water. Use the plunger or drain snake as you pour the water into the drain. If you are wondering how to unclog main sewer line, the pressure of the water will dislodge the debris easily.
It's best to instead opt for a Drano alternative as a safer and more plumbing-friendly way to unclog your drains. Some of the best Drano alternatives include using a plunger or pipe snake, soap or salt mixed with boiling water, or baking soda and white vinegar.
In particular, avoid using vinegar on natural stone surfaces such as marble, granite, and travertine. The acidity can dull these materials over time and may even break down the sealant that protects them from stains.
If baking soda and vinegar didn't work, it usually means the clog is physical—like a mass of hair, heavy grease, or soap scum. When these ingredients are mixed, they simply neutralize each other into salt and water, meaning they lack the force to break through stubborn blockages.
Over time, repeated use of chemical cleaners can weaken pipe walls, warp plastic piping, and corrode older metal lines. This gradual damage often leads to leaks, cracked pipes, and sudden plumbing failures that require emergency repairs. Another problem is that drain cleaners do not solve the real cause of most clogs.
The Cons of Hydro Jetting
Potentially Ineffective Against Severe Obstructions: Hydro jetting dislodges clogs and blockages effectively. It may fall short in tackling severe drain obstructions or damage. Alternatively, different methods may prove more effective, such as rooter or auger drain cleaning services.
Hydro jetting a sewer line typically takes 30 to 90 minutes for a standard residential property. For larger properties, heavily clogged lines, or commercial jobs, the entire service—including setup and final inspection—can take 1 to 2 hours or more.
