Question/query for any pro plumber/heating engineers out there... bear with me as this is my first posting.
Essentially my mother-in-law had to have her boiler replaced about 2 years due to the old one failing - it had a long life prior to this. About 6 months ago we noticed one of the older rads corroding and replaced it - this was the start of a whole series of major problems ultimately culminating in the new boiler having to be replaced again about 2 months ago, under warranty thankfully.
I've since noticed on a recent visit another newer rad corroding and am starting to think there's a significant problem somewhere. My first guess would be that there's no or little inhibitor in the system but wondered if there is anyway of testing? My father-in-law before passing away would have regularly maintained the system, so my only current guess is that when the new boiler (original) was installed the company didn't put cleaner/inhibitor into the system when commissioning the boiler.
First question then is would it be common practice to power flush and or clean then add the necessary levels of inhibitor when installing a new boiler?
Second question... if its not the inhibitor levels in the system what else could be causing the corrosion - it looks like oxygen is getting in somehow but there are no obvious leaks.
Grateful for any ideas.
