What Is High-Pressure Water Jetting and How Does It Work?

High-pressure water jetting is the most effective method for clearing blocked drains, sewer lines, and stormwater pipes. A specialist pump delivers water at pressures of up to 4,000 PSI through a flexible hose and purpose-designed nozzle inserted into the drain. The forward-facing jets cut through the blockage while rear-facing jets propel the hose forward and flush dislodged material downstream to the sewer. Unlike chemical drain cleaners – which are corrosive to pipe materials and rarely resolve a complete blockage – high-pressure jetting physically removes the obstruction and cleans the pipe wall of scale, grease, root material, and sediment. K-Plumbing’s jetting equipment handles pipes from 50mm to 300mm in diameter, covering the full range of residential and light commercial drainage systems. For blockages caused by root intrusion that has damaged the pipe structure, see our sewer line repairs service – which includes pipe relining to seal the entry point permanently. We provide jetting services across Pretoria, Johannesburg, George, and Knysna.

What Types of Blockages Does Jetting Clear?

High-pressure jetting is effective against the full range of drain blockages in South African residential and commercial properties. Grease and fat accumulation in kitchen drain lines is one of the most common causes of slow drains – jetting cuts through accumulated grease and restores full bore flow. Root intrusion from trees and garden plants — particularly in older clay or concrete sewer pipes – is cut and flushed clear, though it does not prevent regrowth. For a permanent root solution, combine jetting with our pipe relining service. Foreign object blockages – sanitary products, wet wipes, building debris – are dislodged and flushed. Scale and mineral deposit buildup in older pipes is removed, improving flow rate and water pressure. As part of our green plumbing approach, we recommend periodic preventive jetting for commercial kitchens and older residential properties to maintain pipe efficiency and avoid emergency blockages.

When Should You Call for Drain Jetting Rather Than a Plunger or Chemical?

A plunger is appropriate for a minor blockage in a single fixture close to the outlet. If the plunger does not resolve the problem within a few attempts, or if multiple fixtures are draining slowly simultaneously, the blockage is deeper in the system and jetting is the correct approach. Chemical drain cleaners should not be used repeatedly – they are corrosive to older pipe materials and harmful to the sewer system. If a drain has been cleared previously and blocked again within six months, recurring blockages indicate a structural issue that may require our sewer line repair service. For emergency blockages causing sewage backup, our team responds 24/7. Call K-Plumbing on 087 094 5048.

Frequently Asked Questions – High-Pressure Drain Jetting

Is high-pressure jetting safe for all pipe types?

Jetting is safe for PVC, CPVC, cast iron, concrete, and clay pipes when carried out at the correct pressure. Older or structurally compromised pipes may require inspection before jetting. K-Plumbing’s technicians assess condition before selecting the correct nozzle and pressure. For pipes that have already failed structurally, see our sewer line repair service.

How long does drain jetting take?

A standard residential drain jetting job is typically completed in 30 to 90 minutes from arrival. Complex jobs with multiple blockages or heavy root intrusion may take two to three hours. For emergency drain blockages causing sewage overflow, we prioritise the call-out. See our call-out fee schedule for pricing.

Can you clear tree roots from a sewer pipe with jetting?

Yes. Jetting with a root-cutting nozzle cuts and flushes roots. However, jetting does not seal the joint through which roots entered, and regrowth is likely within months to a few years. For a permanent solution, our pipe relining service seals the entry point from inside the existing pipe without excavation.

Do you offer drain jetting for commercial properties?

Yes. K-Plumbing handles drainage systems up to 300mm in diameter for restaurants, office parks, apartment complexes, and industrial facilities across Pretoria, Johannesburg, George, and Knysna. Call 087 094 5048 to discuss a scheduled maintenance programme.

Will jetting damage my pipes?

No, when carried out correctly by a trained technician at the appropriate pressure for your pipe type. Jetting is significantly safer than chemical cleaners, which corrode pipe materials over time. If your pipes have existing structural damage, our sewer line repair service addresses this before jetting.
