Foul drain cleaning

Foul drain cleaning is the planned periodic cleaning of the pipes that carry wastewater from toilets, basins, baths, showers and kitchen sinks. The work typically combines high-pressure jetting with vacuum recovery and is documented with a pre and post CCTV survey on commercial sites. Cleaning is essential in food service, healthcare, hospitality and multi-residential buildings, where fat, oil and grease build-ups are a major cause of blockages. The WRc Sewer Cleaning Manual provides the industry standard methodology for cleaning, including pressures, nozzle selection and confined space considerations. Domestic foul drains usually need cleaning only on demand or as part of a planned maintenance contract once recurring blockages have been investigated and the underlying defects, such as displaced joints, have been repaired.
