Central heating sealed system

We recently sealed a central heating system in stockport,We actualy power flushed the system a year previous with no problems with flow etc ,but we did notice at time of power flush that system was infact difficult to Bleed ,the property was a bungalow with the boiler in customers garage wich in turn is a long way from the feed and vent tank in loft area,with flow and return runing vertical for a long way in loft area, The air problem arised when british gas were called to change a pump in property a year after we powerflushed the system, and they coud not get the boiler firing after the pump install,Their conclusion on their report was that the system needed power flushing ,customer called me,and i advised straight away how clean the actual system was left a year previously with inhibitor added etc ,but also advised how bad system was to Bleed at time of power flush,i advised that we seal the system ,wich we did and before we sealed the system ofcouse we had to drain down and the sytem water was very clean from previous power flushing.
We done the work needed in loft area sealed sytem with pressure vessel filling loop and prv etc and pressurised and added inhibitor,Boiler fired straight away with no problems and a happy warm customer again.
