Do you need a power flush in hyde or ashton ?,we completed a powerflush last month in hyde ,all went well ,boiler was a worcester bosch combi ,we fully drained system down and went in through main flow and return ,we got a lot of sludge out of system and the radiators were hot again by the time we had finished the flush ,,and i was also full of tea and coffee ,i must learn to say no sometimes to drinks
