Electro mechanical cleaning is a technique used to clear blockages and de-scale waste pipes.
This is the process of using a motorised tool to rotate a cable or spring which is stored on a drum within the tool. The operator feeds the cable into the pipe that is blocked and uses the tool to rotate the cable within the pipe. This has the effect of breaking up any material which has accumulated in the pipe which is largely removed on the cable and the remainder flushed harmlessly away into the drainage system. The cables are flexible and will pass around several bends easily. Larger machines with larger cables are available for a variety of pipe sizes from 75mm to 100mm.
Each van has a handheld EMC on the van and are usually applied to jobs where there are minor blockages such as sinks, and all waste traps up to 50mm.
