Hi all,
There appears to be a resident sludge in the pipework of my vaillant boiler 828, possibly causing erratic movements of the needle on the pressure gauge. I wondered if I could clear the boiler without having to do the full system flush. Also, I suspect that even if I did the full flush there would still remain some contentious amount of sludge in the boiler perpetuating the problem.I understand there could be loads of other reasons for the pressure gauge wayward behaviour but I would like to eliminate the sludge possibility.So. please advise how the boiler pipe network can be cleaned up.
Many thanks.
