If your prv is leaking take notice of the system pressure when the heating is on, if it reaches 3 bar then your expansion vessel has either failed or it needs re filling with air(0.75bar) its better to change the prv at the same

Download the installation manual, it should have a bit near the end about changing common parts :)

just drain the system so theres no pressure, and using a spanner that fits just undu nuts and replace. after wards refil system. not much to it, just make sure u got the right tools.
