Yes, tree roots will grow back into sewer lines after hydro jetting, typically within 1-3 years depending on tree proximity and pipe condition. Hydro jetting removes existing roots but doesn't prevent regrowth—roots naturally seek moisture and nutrients from cracked or damaged pipes. Long-term solutions include pipe lining to seal entry points, root barrier installation, chemical root treatments, or in severe cases, replacing the damaged section with root-resistant materials and removing problem trees.
Why Tree Roots Return After Hydro Jetting
Tree roots are remarkably persistent when it comes to finding water sources. Your sewer line presents an ideal environment for roots—a consistent source of moisture and nutrients that trees naturally seek out. When you hydro jet your sewer line, the high-pressure water effectively clears out existing root intrusions by cutting through and flushing away the vegetation that has made its way inside your pipes. However, this procedure is essentially a cleaning method rather than a permanent fix.
The fundamental problem remains: if there are cracks, loose joints, or deteriorating sections in your sewer line, roots will eventually find these entry points again. Think of hydro jetting as treating the symptom (root blockage) rather than curing the disease (pipe vulnerability).
How Quickly Roots Regrow After Hydro Jetting
Several factors influence how quickly roots will return to your freshly jetted sewer line:
- Tree proximity: Trees within 10-20 feet of your sewer line pose the highest risk, with fast-growing species like willows, poplars, and silver maples being particularly aggressive.
- Pipe condition: Older clay pipes with numerous joints or cracked pipes provide easy access points for roots.
- Soil conditions: Moist, fertile soil accelerates root growth toward your sewer line.
- Season: Root growth is typically most aggressive during spring and summer months.
For most homeowners, roots will begin to reenter the sewer line within 6-12 months after hydro jetting, with significant blockages potentially reforming within 1-3 years without additional preventative measures.
Effective Long-Term Solutions for Root Problems
While hydro jetting provides excellent temporary relief from root blockages, addressing the underlying issue requires a more comprehensive approach:
Pipe Lining and Rehabilitation
One of the most effective long-term solutions is pipe lining, also known as cured-in-place pipe (CIPP). This process involves installing a resin-saturated liner inside your existing pipe, which then hardens to create a seamless, root-resistant pipe within your old pipe. Benefits include:
- Creates a solid barrier that roots cannot penetrate
- Extends pipe lifespan by 50+ years
- Requires no excavation (trenchless technology)
- Addresses all cracks and joints simultaneously
Root Barriers and Preventative Landscaping
Physical barriers installed between trees and sewer lines can redirect root growth away from your pipes:
- Copper sulfate-infused barriers can be installed vertically in the soil
- Consider removing or replacing problematic trees with species less likely to cause pipe damage
- Maintain at least 20 feet between new trees and sewer lines
Regular Maintenance Schedule
Establishing a proactive maintenance routine significantly reduces the risk of severe blockages:
- Schedule regular hydro jetting every 18-24 months if you have nearby trees
- Consider annual camera inspections to catch root intrusions early
- Use root-killing treatments containing copper sulfate or dichlobenil as recommended by professionals
Chemical Root Control
Between hydro jetting services, chemical treatments can slow root regrowth:
- Copper sulfate-based root killers can be flushed down toilets periodically
- Professional-grade foaming root treatments can coat pipe interiors to inhibit growth
- Note: Always use chemicals according to manufacturer instructions and local regulations
When to Consider Pipe Replacement
In severe cases of repeated root intrusion, especially with aging clay or concrete pipes, replacement may be the most cost-effective long-term solution:
- Modern PVC and HDPE pipes have fewer joints and are more root-resistant
- Seamless pipe installation eliminates many potential entry points
- Though initially more expensive, replacement can prevent recurring costs from repeated hydro jetting
Signs You Need Root Removal Service
Watch for these warning signs that roots may have returned to your sewer line:
- Multiple slow-draining fixtures throughout your home
- Gurgling sounds from toilets or drains
- Sewage backups, especially during heavy water usage
- Lush, green patches in your yard above the sewer line
- Unpleasant odors from drains
