Might need a bit of info if I end fitting it myself although i assume I shut off both valve taps as i did before to isolate the system then just swap it over and repeat the processes of re pressurizing it mate?
If you really do intend to do it yourself please read the manual to familiarise yourself with what to do. Isolate mains electrics to boiler ,and prove its dead.isolate gas supply and cold mains feed to boiler. Partially drain central heating from the lowest point. And add some inhibitor before you top up water pressure once new prv is fitted.

Thanks Terry but i promise if I can get a professional to do it I will. I do have and engineering back ground more mechanical than gas and electric but have some knowledge but again if I can get a pro in I will.
