A power flush is a highly effective, time-efficient means of speeding up a slow system, and dealing with certain forms of blockage. It involves a trained Cavendish plumber using a machine to circulate highly-pressurised water throughout your system. This shifts blockages, and all the gunk and pollutants that can cling to pipes and narrow access ways.
