Rods break through a blockage at one point. A jetting nozzle scours the inside wall of the pipe along its length, removing the grease, scale or silt that catches the next load of debris.
Nozzles are chosen for the job. Some cut through grease, some spin to clean scale, and some are shaped to clear silt or fine roots.
What the work covers
Fat and food deposits cut from kitchen waste pipes and washed to a chamber for removal.
Soil, grit and leaves cleared from gullies and soakaway inlets.
Surface water drains cleared of grit and leaves so water stops standing on the surface.
Hard-water and urine scale cleaned from toilet runs.
Pipes cleaned so a CCTV survey camera has a clear view of the pipe wall.
Questions people ask
What affects the cost of drain jetting?
The length and number of runs, how much build-up there is, how easy the chambers are to reach for the hose and whether an older pipe needs a gentler setting.
Can jetting damage my drains?
It can if the pipe is already weak or the pressure is too high. Old clay and pitch fibre pipes are jetted at lower settings, and a CCTV survey first is sensible if the pipe condition is unknown.
Will jetting fix a drain with tree roots in it?
Jetting with a cutting nozzle can clear fine roots. Roots grow back through a damaged joint, so a lasting fix usually means repairing or lining the pipe.
Is access needed inside the building?
Usually only to the outside inspection chambers. If the only access is through an internal chamber or a rodding eye, someone needs to let us in.
How often should a commercial kitchen drain be jetted?
It depends on how much fat goes down the waste and how often the grease trap is emptied. A drain that slows within weeks of a clean shows the interval is too long.
