Pipeline
Dechoking
When a drain refuses to flow, force-of-water wins. HYVAX deploys high-pressure jetting rated for the toughest blockages (root masses, grease cakes, hardened scale, foreign debris) and immediately vacuum-removes the cleared material. No chemicals, no guesswork.
How It Works
Pressure +
Suction
A high-pressure water jet, fitted with a nozzle designed for the obstruction type, is fed into the line. The jet's reverse-thrust pulls the hose through the blockage while the cutting jet ahead breaks it apart. The dislodged material is simultaneously vacuumed out at the access point.
Industrial Pressure
Pressure ratings dialled to the line: enough to break grease, scale and root mass without damaging modern pipework.
Specialist Nozzles
Flushing, cutting, and root-removal nozzles for every obstruction type. Right tool, right line, right outcome.
Immediate Suction
Cleared debris is vacuumed out at the manhole. No flushing problems downstream, no second blockage.
All Pipe Types
UPVC, RCC, cast iron and HDPE, with diameters from 100mm to large municipal mains. We've worked them all.
The Process
How We Dechoke
A Blocked Line
Diagnose first. Force later. We rarely guess, and we never escalate pressure beyond what the pipe will tolerate.
Stage 01
Rapid Assessment
Identify symptoms, source of blockage, pipe material and age. CCTV used where access allows.
Stage 02
Nozzle Selection
Flushing nozzle for grease, root cutter for organic intrusion, chain knocker for scale, chosen to match the obstruction.
Stage 03
Pressurised Jetting
Hose fed through the line. Jet thrust pulls forward while the cutting head fragments the blockage.
Stage 04
Vacuum Recovery
Dislodged material drawn back to the access chamber and into the sealed debris tank.
Stage 05
Flow Verification
Final flush confirms free-flowing line. CCTV post-check available on request for full visual confirmation.

Common Blockages
What We Clear
If it's stopping flow, we've seen it. We've removed it.
Why Jetting Wins
Faster.
Safer.
Cleaner.
Rodding shifts material short-term but rarely clears the root cause. Chemicals damage pipework and the environment. Jetting solves the blockage, removes the material, and leaves the pipe wall clean.
No Chemicals
Mechanical action only. Safer for operators, infrastructure and waterways.
Root-Cause Removal
Material is extracted, not flushed forward to cause the next problem.
Pipe-Wall Cleaning
Pressure scours the pipe interior, so flow returns to design capacity, not just a partial restore.
24/7 Availability
Blockages don't follow business hours. Our emergency response doesn't either.
Frequently Asked
Common Questions
Within Ernakulam our typical response window is 1-3 hours. Outlying districts may require slightly longer mobilisation. Call us and we'll confirm immediately.
No. Pressure is calibrated to the pipe material and age. Our operators are trained to identify fragile lines and adjust technique accordingly.
No. Mechanical water-jetting is more effective than chemical solutions and avoids damage to the environment and downstream treatment systems.
Yes. we work everything from 100mm domestic lines up to large municipal collector mains. Equipment is matched to the scope.
CCTV post-inspection is available as an add-on, recommended for recurring blockage diagnosis or pre-handover verification.
