See zimmer i find this concerning you clearly either call half a day quite literally half a day or your doing short cuts, power flushing takes hours alone
So unless when you day half a day you mean 12 hours something isn't right combi for combi change yes but ts the power flushing that's getting me on some systems that can take a day on its own depending on if they had a inhibitor no thats for crocks type person in before.
How long are these taking you are they using new pipe work, is the whole of where your based always used cleaning agent and an inhibitor? this just doesn't it with my experience, i am not mocking you how about you explain what your doing enlighten me as i can't see it.
Is every job you come to got a correct and legal gas supply?, previously bonded? Round Rather than Square balanced with an outside wall sufficient away from the boundary (hasn't this distance changed now as well), how long you run the system after install with a cleaner (AFTER THE POWERFLUSH) i.e x300 how many times you fill up and drain? all these little things please assist me with understanding this.
I have only one problem with you from what i have read so far and that is clear you left a bleed valve open in a customers house on purpose, the rest i just don't believe your doing it properly if you are taking 1/2 a day
