Home / Services / Drainage / Jetting

Our vehicles are supplied with all necessary equipment including high pressure jetting systems, that can be essential to any drainage inspection.

Chelmer clear blockages and pipework in drainage runs using the latest high pressure water jetting equipment. Operations are carried out mainly from Van Pack Jetting machines delivering 4000psi (subject to WJ sewer jetting code of practice) and the use of specialised jetting nozzles to tackle problems from sludge up to encrusted concrete.

Jet Vac Combination Tankers are the system utilised by our Operatives in procedures which involve clearing larger pipes and emptying septic tanks and removing sand or silt from building sites or communal areas and even grease trap maintenance.
