Have you noticed strange odors coming from your sink, or your drains seem slow lately? If so, you might need professional sewer and drainage line cleaning. A drainage line keeps wastewater off of your property. It’s crucial to maintain these pipe systems free of obstructions to allow water to flow freely and prevent backup or floods. 

Those who are not skilled in plumbing maintenance may find it overwhelming. However, professional plumbing services can help you clear your clogged drains. In this post, we’ll share practical tips for cleaning your sewer and drainage line.

5 Signs Your Sewer and Drainage Line Needs Cleaning

Most households take sewer pipes for granted. When an issue arises, you’ll know if your sewer needs cleaning. Smells, strange noises, and slowly flushing drains are signs that something is wrong with your sewer system. Sewer and drainage cleaning can be time-consuming, and you don’t have the equipment to solve every issue in your sewer line.

Here are some signs your drainage and sewer lines need cleaning:

  • Slow Drainage — If you notice water draining slowly from sinks, showers, tubs, or toilets, it could be a sign of a partial blockage in the sewer or drainage lines. Slow drainage indicates that water is having difficulty passing through the pipes due to buildup or obstruction.
  • Foul Odors — Unpleasant odors emanating from drains, toilets, or the area around sewer cleanouts may indicate a buildup of organic matter or sewage within the pipes. Foul smells can be a sign of stagnant water, decomposing waste, or blocked ventilation, all of which may necessitate cleaning of the sewer and drainage lines.
  • Gurgling Noises — Gurgling or bubbling noises coming from drains, toilets, or other plumbing fixtures when water is draining can indicate air trapped in the pipes due to blockages. These noises may occur as air attempts to escape through the water, suggesting that the sewer or drainage lines may need cleaning to restore proper airflow.
  • Multiple Clogged Fixtures — If multiple plumbing fixtures in your home are experiencing simultaneous or recurrent clogs, it could indicate a blockage further down the sewer or drainage line. When multiple fixtures, such as sinks, showers, and toilets, are affected, it suggests a common issue in the main sewer line that requires professional cleaning.
  • Backups and Overflows –- Sewage backups or overflows in drains, toilets, or cleanouts are clear indicators of a serious blockage or obstruction in the sewer or drainage lines. If wastewater is backing up into your home or pooling around drains, it’s crucial to address the issue promptly to prevent property damage and health hazards.

7 Effective Tips for Sewer and Drainage Line Cleaning

Every drainage line connects to your home’s sewer system. All drains, be they in a sink, shower, or toilet, connect to the sewer pipes that exit your home. These pipes connect to the main sewer line. Regular sewer and drainage line cleaning will help lessen pipe damage and save you money on costly plumbing repairs. At Hansen’s Plumbing and Remodeling, our professionals can identify and fix any sewer and drainage line problems.

Chemical Treatments

Utilize environmentally safe chemical treatments to break down organic matter and prevent buildup within sewer and drainage lines. Biodegradable enzymatic cleaners or microbial treatments can help digest grease, fats, and other organic materials, reducing the risk of blockages and odors.

Grease Trap Maintenance

If your property or establishment has a grease trap installed, ensure it is regularly cleaned and maintained according to local regulations. Grease traps capture fats, oils, and grease (FOG) from wastewater before they enter sewer lines, preventing clogs and sewer backups. Schedule professional pump-outs as needed to keep the grease trap functioning effectively.

Sump Pump Inspection

If you have a sump pump installed to manage excess water, inspect it regularly to ensure proper operation. Clear debris from the sump pit and intake valve, test the pump’s functionality and replace worn or malfunctioning parts promptly. A well-maintained sump pump helps prevent flooding and water damage in basements and low-lying areas.

Professional Drain Cleaning

Periodically, it’s beneficial to hire a professional plumber for thorough drain cleaning. These services utilize high-pressure water jets or augers to remove stubborn blockages and buildup from the pipes. This deep cleaning can significantly improve the flow and efficiency of your drainage system.

High-Pressure Water Jetting

Invest in or hire professionals with high-pressure water jetting equipment to effectively clear stubborn blockages and debris from sewer and drainage pipes. This method utilizes pressurized water to dislodge and flush out obstructions, restoring flow and preventing future clogs.

Root Removal

Tree roots are a common cause of sewer line blockages, as they can penetrate pipes in search of water and nutrients. Consider using root foaming agents or mechanical root cutters to clear roots from the pipes and prevent further intrusion. Additionally, planting trees away from underground pipes can help mitigate root-related issues in the future.

Regular Maintenance

Implement a proactive maintenance schedule to keep sewer and drainage systems in optimal condition. This may include periodic cleaning, flushing, and maintenance tasks such as snaking drains or hydro-jetting. By staying ahead of potential problems, you can minimize the risk of disruptive and costly sewer backups.

Frequently Asked Questions

How often should sewer and drainage lines be cleaned?

The frequency of cleaning depends on various factors, including the type of property, usage levels, and the presence of trees or vegetation near sewer lines. Generally, it’s recommended to schedule routine cleaning at least once every 1-2 years for preventive maintenance. However, properties with heavy usage or known issues may require more frequent cleaning.

Can I clean sewer and drainage lines myself, or should I hire a professional?

While minor blockages can sometimes be cleared using DIY methods such as plungers or drain snakes, more stubborn or complex issues often require professional intervention. Professional plumbers have specialized equipment and expertise to safely and effectively clean sewer and drainage lines, ensuring thorough removal of blockages and preventing damage to pipes.

What methods are used to clean sewer and drainage lines?

Common methods of cleaning sewer and drainage lines include mechanical snaking, hydro-jetting (high-pressure water blasting), chemical treatments, and root cutting. The choice of method depends on the nature and severity of the blockage and the condition of the pipes.

How can I prevent future blockages in sewer and drainage lines?

Preventive maintenance measures include proper waste disposal practices (e.g., avoiding flushing non-biodegradable materials), installing drain guards or screens, scheduling regular inspections, trimming tree roots near sewer lines, and implementing root barriers. Additionally, adhering to a routine cleaning schedule can help prevent the buildup of debris and grease.
