I am A.C.O.P. engineer used to working with multy fuel high temp and pressure
I know service engineers change out parts untill they get it right
I can work on domesticks if its on industrial sites least i did when i was working.
What I was infering is that as ACOPS finished about 15 years ago and only last for 5 years then for the last 10 years or so you have not been gas registered.
If you retired as gas registered then you might have qualified for the CC but I doubt it if you either work illegally or changed your career.
I dont see any connection between flame picture and water pressure.
Correct retired at 67 when mi corgi finished now 76.
this is my boiler got it as end of line from my frends at Plumb centre.
