Please can someone comment on the working pressure of boiler.
My mate is an RGI.
I am a quali plumb and i am training to be RGI.We changed a boiler and tested it but the working pressure dropped from 20mbar(standing pressure) to 10mbar(working pressure) and it seemed to be working fine but my mate doesnt shrug and said its ok hence it is working fine.
CAn someone elaborate on this please.
