Just a quickie - what would you recommened the best way/quickest and easiest way to replace a PRV in a combi boiler - as turning off the isolation valves often results in a leak. Is it best to drain the system pipework ?

Drain through prv as your changing it anyway.don't touch iso valves
You wont have to drain the whole system. Close any AAVs and once the pressure has been realeased from the system you will hve created a vacuum.
