Water in central heating system is contaminated with rust, sludge and other debris because of internal corrosion. This corrosion products are causing circulation and boiler noise problems, premature failures of heating system components and reducing system efficiency (increasing your fuel bills). System needs to be flushed and cleaned and the best solution is powerflush. The Clearflow CF90 Quantum power flushing pump is simply connected into the heating system, either across standard circulator pump couplings, across the tails of one radiator, or wherever most practicable. The powerful flow, combined with instantaneous flow reverser device, will dislodge and mobilise deposits and corrosion which resist traditional system cleaning methods. Once the corrosion and sludge deposits have been loosened and mobilised, fresh clean water is forced through the heating system, pushing the contaminated water out through a full bore dump valve to waste. During the process, radiators are individually flushed, without removing or disconnecting them from the system, by directing the full output of the pump through each radiator separately.
