Fast, high-pressure jetting for stubborn blockages, grease build-up, foul smells, and repeat drainage issues across London and South London.
Professional drain jetting in Greater London
If you’ve tried to clear your blocked drain but are still facing issues, your drainage system may need professional jetting. At HydraFlow, we use commercial high-pressure water jetting equipment to clear stubborn blockages quickly and properly.
Whether it’s blocked drains, toilets, gullies, or recurring build-up in underground pipework, we use jetting to restore full flow, clean the pipe walls, and reduce the chance of the same problem coming straight back.
More effective than rods for stubborn blockages
High-pressure drain jetting uses a controlled jet of water to break up grease, scale, sludge, wipes, and other debris inside the pipe. It is one of the most effective ways to deal with heavy build-up because it clears the blockage and helps clean the line behind it.
When do you need drain jetting?
Recurring blockages
When the same drain keeps blocking again after temporary clearing.
Slow drainage
Sinks, baths, and showers draining sluggishly due to build-up inside the pipe.
Blocked outside drains
Ideal for gullies, channels, and external drainage runs holding debris or silt.
Bad smells
Useful where stagnant waste and grease are creating foul drainage odours.
Sewage backup risk
Helps restore flow when waste water starts backing up internally or externally.
Commercial maintenance
Good for restaurants, rented property, and higher-use drainage systems.

Frequently Asked Questions — Drain Jetting
How long does drain jetting take?
Most residential drain jetting jobs take between 30 minutes and 2 hours, depending on the length and condition of the drain. Commercial or more complex systems may take longer. We will give you an estimate when we assess the drain on arrival.
How often should drains be jetted?
For most domestic properties, drain jetting every 18–24 months is a good preventive measure. Properties with trees nearby, older drainage systems, or a history of blockages may benefit from annual jetting.
Is drain jetting safe for older pipes?
Modern jetting equipment is adjustable in pressure. Our engineers assess the pipe condition before starting and use appropriate pressure settings. We will let you know if a pipe is too fragile for jetting and recommend an alternative approach.
