High Pressure Water Jetting Efficient drainage is never a problem until it stops working. All drainage systems need cleaning at some point in time. Scale, silt, fat and grease inevitably accumulate, reducing capacity and flow, and can even cause a total blockage.  High pressure water jetting is an effective cleaning technique for use in drains, sewers and pipework systems. It can be used to remove relatively soft silt or hard solid-set substances such as scale or cement.

Blockages in drains, sewers and stack pipes can be cleaned using this highly effective technique. Powerful jets of water developing pressures of up to 4,000 psi strip deposits from pipe walls, flush out debris and restore free-flowing conditions.  High pressure water jetting can also be used to ensure that process pipework is clean and clear of obstructions. Naturally, when scale and residue build up, manufacturing efficiency declines. Using specialist equipment, pressures of up to 30,000 psi are used to cut through blockages and remove seemingly solid deposits from pipe walls.

CCTV Surveying When structural problems are suspected in drains and pipework they need to be accurately identified and diagnosed. The more accurate the diagnosis, the more accurate the solution. That’s the philosophy behind JHS Closed Circuit Television Surveys.  Specially developed state-of-the-art camera technology, which produces high quality colour pictures, allows the JHS engineer to take a ‘close-up’ look at the inside of drains, pipes and sewers. These surveys identify the cause and nature of blockages whilst checking for internal conditions and pipework integrity.  The camera is propelled through the pipework by either a semi-rigid rod or powerful tractor to distances of up to 300 metres.  Pipes with internal diameters ranging from 25mm to 900mm can be inspected and the results used to determine the most practical and cost-effective method of repair.
