Drain jetting is one of the most effective methods for clearing blocked drains and maintaining healthy drainage systems. Used by professional drainage engineers across the UK, it relies on high pressure water rather than rods or chemicals to remove blockages and restore full flow.
If you are dealing with recurring drainage issues, slow drains or stubborn blockages, understanding how drain jetting works can help you decide when professional intervention is the right solution.
What is drain jetting?
Drain jetting, also known as high pressure water jetting, is a method of cleaning drains using powerful jets of water to remove grease, debris, silt, scale and other build up from inside pipework.
Unlike traditional rodding, which may only punch a hole through a blockage, drain jetting cleans the full internal diameter of the pipe, helping to prevent the problem from returning.
How does drain jetting work?
Drain jetting works by combining water pressure and controlled flow to break down blockages and flush debris safely through the drainage system.
The process typically involves:
- Accessing the drain via a manhole or access point
- Feeding a jetting hose into the pipework
- Using rear facing jets to pull the hose through the drain
- Breaking down grease, debris, silt or scale
- Flushing loosened waste away from the system
Different jetting nozzles are used depending on the type of blockage and the condition of the drain.
What types of blockages can drain jetting clear?
Drain jetting is suitable for a wide range of drainage problems, including:
- Grease and fat build up from kitchens
- Food waste and organic debris
- Silt and sediment
- Soap and detergent residue
- General debris and scale
It is particularly effective for recurring blockages caused by grease, which often require specialist cleaning solutions rather than simple rodding.
Is drain jetting safe for pipes?
When carried out professionally, drain jetting is safe for most modern drainage systems.
Water pressure is carefully adjusted based on the pipe material, diameter, age and condition. In many cases, jetting is safer than repeated use of chemical drain cleaners, which can damage pipework over time.
If a drain is suspected to be damaged or very old, a professional inspection may be recommended before jetting takes place.
Drain jetting vs rodding and chemicals
While drain rods and chemical cleaners can sometimes provide short term relief, they often fail to address the underlying cause of a blockage.
Drain jetting offers several advantages:
- Cleans the entire pipe, not just the blockage
- Reduces the likelihood of recurring issues
- Does not rely on harsh chemicals
- Suitable for domestic and commercial drains
For stubborn or recurring problems, jetting is usually the most effective long term solution.
When is professional drain jetting needed?
Professional drain jetting is recommended when:
- Blocked drains keep returning
- Water drains slowly despite rodding
- There are foul smells from drains
- Grease build up is present
- Commercial drainage systems require routine maintenance
In urgent situations, jetting can quickly restore flow and may avoid the need for more disruptive repairs. Learn more about our emergency drainage services.

Frequently asked questions
How long does drain jetting take?
Most domestic drain jetting jobs are completed within one to two hours, depending on the severity of the blockage and access to the drainage system.
