BDS Engineers attend private and commercial properties to carry out high pressure water jetting to all accessible drainage pipes after diagnosing the problem when arriving. We make it the engineer’s priority to clean & unblock drainage which is affecting the facilities. We also allow time to disinfect areas leaving all drainage in a free flow condition. BDS Engineers also clean out & manually empty aco drains. The use of other machinery is required for internal blockages and clearance of small diameter pipework, which includes the use of electro-mechanical cleansing machines and chemicals. Root-cutting, de-greasing & de-scaling of pipework would be included in all work carried out by BDS Engineers.
