How To Get Rid Of Tree Roots In Sewer Line

Table of Contents

TLDR

To get rid of tree roots in a sewer line, use a combination of mechanical removal methods like augering or hydro jetting, and chemical root killers such as copper sulfate or foaming treatments. For severe damage, trenchless pipe repair or full replacement is required.

Understanding Why Tree Roots Invade Sewer Lines

Understanding Why Tree Roots Invade Sewer Lines

Tree roots enter sewer lines because they are drawn to moisture and nutrients leaking from tiny cracks or joints in pipes. Once inside, roots expand and cause blockages.

Why roots grow toward sewer pipes

Roots search for water. Sewer pipes provide a constant supply of moisture and nutrients. Even the smallest crack or joint can attract aggressive root growth.

Common pipe types affected

  • Clay pipes: highly vulnerable due to porous surfaces

  • Cast iron pipes: stronger, but joints still allow intrusion

  • PVC or HDPE: more resistant, though poorly sealed joints remain at risk

Signs of Tree Roots in Sewer Line

Recognizing symptoms early prevents costly damage.

Slow drains and recurring clogs

If your sinks or toilets drain slowly even after cleaning, roots may be inside your line.

Gurgling sounds and foul odors

Air pockets form when roots trap waste, leading to gurgling noises and sewer gas smells.

Sewage backup inside home

Wastewater backing up into tubs, showers, or toilets is one of the most serious warning signs.

Green patches in the yard or sinkholes

Excess moisture escaping from broken pipes creates lush patches of grass or small sinkholes.

DIY Methods to Remove Tree Roots From Sewer Pipes

DIY Methods to Remove Tree Roots From Sewer Pipes

For minor blockages, some homeowners try DIY solutions before calling professionals.

Using copper sulfate or rock salt as root killers

  • Copper sulfate crystals are flushed down the toilet. They poison roots inside pipes.

  • Rock salt works by dehydrating roots, though results are slower.

  • Both need repeated applications and do not fix broken pipes.

Mechanical augers and root cutting tools

  • A drain auger or sewer snake cuts through root blockages.

  • Machines can be rented, but improper use risks damaging pipes.

Hydro jetting for aggressive root removal

  • High-pressure water blasts roots from pipe walls.

  • More effective than augers, but usually requires a professional.

DIY fixes help temporarily, but professional methods ensure long-term results.

Sewer camera inspection before treatment

A small camera is inserted to locate root intrusion, measure severity, and guide repair options.

Hydro jetting and mechanical root cutting

Plumbers use industrial equipment to fully clear roots and debris.

Trenchless repair methods

  • Pipe lining: installs a resin-coated liner that hardens inside the old pipe
  • Pipe bursting: breaks the old pipe while pulling in a new one
  • Both avoid digging up the yard and provide long-term protection

Full sewer line replacement when necessary

If damage is extensive, a full replacement is unavoidable. In some cases, the intrusion is so severe that clearing roots only provides short-term relief, making it the right time to replace a sewer line rather than continue temporary fixes.

  • Minor repairs: $200 to $1,000
  • Hydro jetting or camera inspections: $300 to $800
  • Trenchless repairs: $3,000 to $7,500
  • Full replacement: $8,000 to $15,000

Safety considerations with chemicals

Copper sulfate and similar chemicals are toxic. They require protective gear and can damage septic systems.

How to know when damage is too severe

If backups continue after DIY attempts, professional help is necessary. Multiple clogs, foul odors, or interior flooding signal structural damage.

Sewer Solutions advises calling a licensed plumber if you notice recurring issues.

FAQs About Tree Roots in Sewer Lines

Can tree roots permanently damage sewer pipes?

Yes. Roots expand cracks, collapse pipes, and lead to costly replacement.

What is the fastest way to kill tree roots in pipes?

Hydro jetting is the fastest method. Chemicals take longer.

How often should I inspect my sewer line for roots?

Annual inspections are recommended, especially if you have older pipes.

Will insurance pay for sewer line root removal?

Most insurance policies exclude root intrusion unless it causes a covered peril.

What trees are most likely to invade sewer lines?

Willows, oaks, maples, and poplars are high-risk due to aggressive root systems.

Are PVC pipes safe from root intrusion?

PVC is more resistant than clay or cast iron, but poorly sealed joints remain vulnerable.

Many modern sewer systems, including ATUs, come with alarms that notify you of issues such as low air pressure or system malfunctions. If your alarm goes off:

  1. Do not ignore it. The alarm is designed to alert you to problems that may need professional attention.
  2. Contact a professional: Reach out to a licensed service provider or installer to inspect the system and perform necessary maintenance.

Recognizing the early signs of a failing sewer system can help you avoid costly repairs and health hazards. Look out for these common indicators:

  • Slow drains: If your sinks, showers, or toilets drain slowly, it may indicate a clog or backup in your septic system.
  • Unpleasant odors: Foul smells around the drain field, septic tank, or inside your home could mean there is a problem with the system.
  • Standing water or wet spots: If you notice soggy patches of ground near the septic tank or drain field, this could be a sign of overflow or system failure.
  • Backed-up sewage: A severe backup of sewage inside the house is a major red flag that your septic system is malfunctioning and needs immediate attention.
  • Lush green grass over the drain field: If the grass over your drain field is unusually green and lush, it may indicate an excess of untreated wastewater.

If you notice any of these symptoms, it’s important to call a professional sewer service provider for an inspection and possible repair.

As a sewer system owner, there are a few key responsibilities to ensure your system works properly and lasts longer:

  • Keep the area clear: Avoid placing vehicles, heavy equipment, or structures over your septic tank or ATU. Roots or pests (like fire ants) should be kept away from the system.
  • Monitor the system: Regularly check the system’s operation and make sure the control panel is functioning properly. If your system has an alarm, ensure it’s working and responds to malfunctions.
  • Avoid overloading: Use water efficiently, and avoid flushing non-biodegradable items or harmful chemicals (like bleach or disinfectants).
  • Professional service only: Always have licensed professionals perform inspections and repairs. Unauthorized servicing can cause damage or void your warranty.

The frequency of sewer system pumping depends on the type of system you have and how much water your household uses. Here are some general guidelines:

  • Septic tanks: Pump every 3-7 years, depending on your water usage and the size of your tank.
  • Aerobic Treatment Units (ATUs): These systems typically require less frequent pumping due to their more efficient treatment, but you may still need to pump every 5-10 years or as needed.

 

Regular maintenance checks are crucial. If you notice odors, slow drainage, or unusual discharges, it may be time for an inspection or pump-out.

For your sewer system to function efficiently, it’s important to use only approved products. Here’s a list of safe items for your system:

  • Household cleaners: It’s safe to use household cleaners in moderation, provided they follow the directions on the label. Avoid excessive use, especially with bleach or harsh chemicals.
  • Toilet paper: Only use biodegradable toilet paper designed for septic systems.
  • Laundry detergent: Use sewer-safe detergents in recommended amounts.

 

However, certain products should never go into your sewer system, including:

  1. Large amounts of bleach or disinfectants that kill bacteria
  2. Feminine hygiene products, diapers, and other non-biodegradable items
  3. Cooking oils, grease, coffee grounds, or shrimp shells
  4. Chemical drain cleaners
  5. Plastics, rubber, and large paper products

 

These items can harm the system’s bacteria or cause blockages, reducing efficiency and increasing maintenance needs.

Both Aerobic Treatment Units (ATUs) and septic tanks treat wastewater, but they use different methods:

  • Septic Tank: A septic tank relies on anaerobic bacteria (bacteria that do not require oxygen) to break down waste. The wastewater is held in the tank where solids settle, and liquids are filtered out. Over time, sludge builds up at the bottom of the tank, requiring periodic pumping.
  • Aerobic Treatment Unit (ATU): An ATU uses aerobic bacteria (bacteria that require oxygen) to break down organic waste. Air is pumped into the unit, promoting a more efficient biological process. This method results in cleaner effluent (treated wastewater) and often requires less frequent pumping.

 

Key Differences:

  • Aerobic systems (ATUs) are generally more efficient, producing cleaner treated water and requiring less maintenance.
  • Septic tanks are simpler but can require more frequent pumping and can produce less treated effluent.
