Hydro Jetting in Highlands, BC
Highlands' dense forest cover sends aggressive root systems into septic-connected drain lines on nearly every property. Hydro jetting with a root-cutting nozzle is the most effective way to clear root masses and restore flow — and we pair every job with camera inspection to protect your septic system.
What Highlands Homeowners Say About Our Hydro Jetting Work
Real Victoria homeowners. Real jobs. Real results.
"I called two other plumbing companies, left messages, neither one called me back. Then I tried another who couldn't see me for 6 weeks. Then I found Clear Choice — they sent someone the very next day. Fast, friendly, professional. They have my business from now on."
"Awesome experience with The Clear Choice Plumbing & Heating. Two days after we moved into our new home, our laundry room flooded when we drained the bathtub. They were able to get Tyler in right away. He found major issues with our cast iron sewer line and had it completely resolved within days. Outstanding service."
"I had an issue with my shower drain. Jennifer took my call, called me back within 20 minutes, and arranged a plumber to come the very next morning. The plumber arrived on time, was professional, and resolved the issue quickly. I would highly recommend Clear Choice to anyone."

Root intrusion is the dominant drain problem in Highlands — and hydro jetting is the most effective tool for clearing it. Nearly every property in the municipality sits on a large forested lot with mature Douglas fir, cedar, and deciduous trees whose root systems aggressively seek out the moisture in drain and septic lines. Properties along Millstream Road, throughout the Caleb Pike area, up Munn Road and Finlayson Arm Road, and along the Highlands end of Happy Valley Road all face the same challenge. A standard drain snake punches a hole through a root mass; hydro jetting shears roots at the pipe wall and scours the full interior of the pipe clean — a fundamentally more thorough clearing.
Why Highlands Needs Hydro Jetting More Than Most
The combination of dense forest cover and septic-connected drain lines makes Highlands one of the highest root-intrusion areas we service in Greater Victoria. Here's why the problem is so persistent.
Highlands is the most rural and heavily forested municipality in Greater Victoria. Properties along Munn Road and Finlayson Arm Road are surrounded by mature forest with root systems that extend far beyond the tree's drip line. The large lot sizes — many are half an acre to several acres — mean drain and septic lines run longer distances through root-active ground than they would on an urban lot in Victoria or Saanich.
The 1980s-90s ABS drain pipe used in most Highlands homes is more root-resistant than old clay tile, but roots still enter at joints, connections, and any point where the pipe has shifted from soil movement or frost heave. Once inside, roots grow rapidly in the nutrient-rich environment of a drain line and form dense mats that catch waste and progressively narrow the pipe. A snake punches a temporary channel through the mat; hydro jetting removes the root mass entirely and restores the pipe to its full diameter.
Septic-Safe Hydro Jetting for Highlands Properties
Because nearly all Highlands homes are on private septic systems, hydro jetting has to be performed with the septic system's health in mind. A careless approach can flood the septic tank with high-pressure water, disturb the settled solids, damage the bacterial colony that breaks down waste, or — worst case — damage the drain field distribution pipes.
Our approach for Highlands septic-connected systems:
Camera inspection before jetting. We identify exactly where the blockage sits — in the house drain, the line to the septic tank, or the effluent line to the field — before we introduce any pressure. The camera also shows us the pipe material and condition so we can adjust pressure accordingly.
Directed jetting. For blockages in the house-to-tank line, we direct the jetting toward the house side of the blockage so debris flushes back toward the cleanout rather than into the septic tank. For effluent line blockages, we work with carefully controlled pressure to avoid damaging the field distribution network.
Root-cutting nozzle. For root masses — the most common Highlands blockage type — we use a specialized root-cutting nozzle that shears roots at the pipe wall with rotating high-pressure jets. The cut roots flush through the system while the pipe wall is scoured clean. Properties in the Caleb Pike area and along Millstream Road with trees close to septic lines are the most frequent candidates for this service.
After Jetting: When Clearing Isn't Enough
Hydro jetting removes what's inside the pipe — but it doesn't fix the entry points where roots are getting in. After clearing, we run the camera again to document where roots entered and assess the structural condition of the pipe.
If root intrusion is limited to one or two joints, preventive jetting on a regular schedule (typically every 18-24 months) can keep the line flowing between more permanent interventions. Many Highlands homeowners on the Millstream Road and Happy Valley Road corridors are on a maintenance jetting schedule that prevents emergency backups.
If roots are entering at multiple points along the run — which is common on the most heavily forested lots along Finlayson Arm Road and Munn Road — the honest recommendation is full sewer line replacement with modern continuous pipe (HDPE or heavy-wall PVC) that eliminates the root entry points entirely. We'll show you the camera footage and let you make an informed decision. If your home also has aging Poly B supply lines, coordinating both projects can reduce overall disruption.

Yes, when done correctly. We direct the jetting toward the house side of the blockage — away from the septic tank — so we're not flooding the tank with high-pressure water that could disturb the settled solids and bacterial colony. For effluent line blockages between the tank and the drain field, we work with particular care to avoid damaging the field distribution pipes. Camera inspection before jetting tells us exactly where to work and how to protect the septic system.
The hydro jetter uses a rotating nozzle that fires high-pressure water jets forward and backward simultaneously. The forward jets cut through root masses and the rearward jets propel the head through the pipe while scouring the pipe walls clean. A root-cutting nozzle specifically designed for root work shears roots at the pipe wall. The roots are flushed through the system. We follow up with camera inspection to confirm the line is clear and to document where roots entered the pipe.
For Highlands properties with documented root intrusion — which is most of them — we recommend preventive jetting every 18-24 months to stay ahead of regrowth. Properties along Munn Road and Finlayson Arm Road with the densest forest cover may need more frequent service. We give you a recommended interval based on what the camera shows after the initial clearing and the species and proximity of trees near your drain lines.
Hydro jetting removes the roots and buildup inside the pipe, but it doesn't repair the entry points where roots are getting in. For recurring backups caused by root intrusion at multiple joints — common on forested Highlands lots — hydro jetting is an effective maintenance tool that keeps the lines flowing between more permanent interventions. If roots are entering at many points along the run, the long-term fix is full sewer line replacement with continuous pipe that eliminates the entry points.
Yes. We run a camera inspection before jetting to assess the pipe condition and identify the blockage type and location. This is critical in Highlands because of the septic system context — we need to know exactly where the blockage sits relative to the tank and field before choosing our approach. We also run the camera after jetting to confirm the line is fully clear and to document the pipe condition for your records.
Cost depends on the scope — which lines need jetting, the length of the runs, access to cleanouts, and the severity of the root intrusion. We include a pre-jetting camera inspection in every hydro jetting job so you know what you're paying for and why. We provide upfront pricing before work begins. Call (778) 265-6446 to book.
