Is Your Sewer Line Clogged? Here’s How to Clean It Right

If you’re noticing slow drains, sewage smell, or water pooling near your home, these could be tell-tale signs of a clogged sewer line. Ignoring it can lead to wastewater backups, plumbing emergencies, or even water damage.

Fun fact: A single tree root can grow over 20 feet in search of moisture—right into your sewer line. One root can cost you thousands in repairs if left unchecked.

This blog covers the best ways to clean a sewer line, what causes blockages, and how much sewer line cleaning costs—so you can take smart, timely action.

What Causes a Sewer Line to Clog?

Sewer line issues can happen to any home, especially an older home with aging pipes. Some common causes include:

• Tree roots breaking into the sewer pipe
• Grease, soap scum, and solid waste buildup
• Flushing baby wipes, paper towels, or feminine hygiene products
• Collapsed or broken pipe segments
• Heavy buildup of human waste and food debris

These issues disrupt water flow and can affect your entire plumbing system.

Tell-Tale Signs You Need Sewer Line Cleaning

Here are the most common warning signs:

• Gurgling sounds from toilet drains
• Foul sewage smell indoors or around your yard
• Bathroom sink or shower drain emptying slowly
• Clogged toilet or multiple fixtures backing up
• Fluctuating water level in toilets
• Recurring clogged drain issues across your home

If you’re experiencing any of these, it’s a good idea to call a professional plumber right away.

Best Ways to Clean Out a Clogged Sewer Line

1. Drain Snaking

A plumbing snake (aka drain auger) is used to snake out blockages close to the drain opening.

• Best for: Mild clogs near fixtures
• Tools used: Drain snake, plumbing auger
• Caution: May not clear deep-rooted clogs or tree roots

2. Hydro Jetting

Hydro jetting uses a pressure hose with a strong water stream to clear out built-up debris, grease, and roots.

• Best for: Stubborn clogs and full pipe cleaning
• Effective way to prevent sewer blockage and ensure clean drains
• Avoid in fragile PVC pipe systems without inspection first

3. Sewer Camera Inspection

Before serious work begins, drain cleaning services often use a camera to locate the clog.

• Identifies: Root intrusion, main sewer line clog, or a broken pipe
• Helps avoid unnecessary sewer line replacement

How Much Does Sewer Line Cleaning Cost?

Depending on the severity of the clog and the method used, here are average price ranges:

Cost varies based on your location, the extent of the clog, and whether it’s a clogged main sewer line or a smaller blockage.

Home Remedies for Minor Sewer Line Issues

While major clogs require a professional plumber, you can try:

• Pouring boiling water with dish soap into slow drains
• Using a plumbing snake or chemical cleaner (with caution)
• Trying a dry vacuum to pull the blockage (if close to the drain cover)

Avoid mixing chemicals—they can create a dangerous chemical reaction. And never flush coffee grounds, eggshells, or flushable wipes.

When to Call for Sewer Line Repair

If you’re facing a full sewer drain clog, root intrusion, or collapsed pipe, it’s time for sewer line repair or even sewer line replacement. Ignoring serious plumbing issues can lead to sewage water backup and health hazards.

Your professional plumbing team can inspect, snake, or jet the line, and advise if pipe lining is an option before digging up your yard.

How to Prevent Future Clogs

Help your plumbing system stay healthy:

• Don’t flush baby wipes, paper towels, or solid waste that isn’t human
• Dispose of grease in the trash
• Use rooter service every 12–18 months
• Install a sewer line cleanout for easy maintenance
• Get annual inspections for older homes

Regular maintenance is the most cost-effective way to avoid major plumbing repair expenses.
