Drains can become blocked and ineffective for a number of different reasons and to effectively clean drains of all varieties requires a flexible and versatile approach. Although often the most efficient technique, sometimes high pressure water jetting isn’t possible due to spatial or structural limitations.
What is it?
One solution is to use electro mechanical drain cleaning. A simple yet effective method, a motor is used to drive a cable through a pipe or drain in a boring motion similar to a drill, constantly rotating the cable in a clockwise direction. Water is often simultaneously fed into the pipe to flush out any obstructions. The cable itself can be fitted with various cutters as dictated by the blockage, and the technique is ideal for removing a number of robust blockages, as well as residue build-up such as lime scale, uric scale and concrete deposits. In some cases, the technique is used in conjunction with acid drain cleaning, although this presents a number of health and safety risks and is best used sparingly.
The electro mechanical drain cleaning method was pioneered by the Dyno-Rod company in the 1960s, and is a common service provided by many drainage companies today.
When is it used?
Electro mechanical drain cleaning is a great way to clear blockages from internal pipework where drain jetting could cause damage or flooding, such as toilets, sinks, washing machines and dishwashers, but can be used on larger underground drains where restricted access means jetting is not possible. Sometimes referred to as a ‘plumber’s snake’, the cable provides the flexibility to bore into narrow and twisting pipework, and those that utilise springs are able to retain a powerful cleaning action through long sections of drain and around multiple corners.
How is it used?
Different sizes and styles of electro mechanical drain cleaner are used for different applications. Specialist root cutters must be used for the removal of tree root ingress, while much larger machines are required for blocked soil stack pipes. Where grease and cooking fats are causing the issue, running hot water through the pipes as the cable is fed through produces effective results, although high power water jetting is best in these situations if possible.
In most scenarios, it is the front of the cable that removes blockages caused by a clogging of hair or solid objects, boring into the obstruction like a corkscrew, while the main body of the cable removes fatty deposits and other build-ups from the internal walls of the pipe using the rotating motion.
