The only fairly safe way to avoid them leaking is to take out all the pressure before you turn them....but I would never touch them, had a frigger the other month that leaked from the iso valve o ring after changing the expansion vessel.... was there 9 hours!!
forget the diverter, the vessel is the worst job on these turds. i only replace them if they are leaking, otherwise an external one gets fitted.
It was leaking but the trouble was I had the genuine part ordered...if it were me I would have cut the pipe and capped it then fitted an external!
Took 5 drain downs as it was moving parts which had never been moved before and needed another full strip and couple of new o rings every time.....never again.
thats why these turds take up so much time. only an alpha cbx would require more multiple draindowns to repair erroneous leaks after the initial repair.
