Hi All,
Thanks for this great forum, followed some advice in another Vaillant thread I found earlier. My 'in laws' need a new expansion vessel, the water spewing out of it into my bike pump was a bit of a giveaway..
I was hoping somebody could tell me the process for changing said vessel, it looks like it might be:
drain system
unscrew connection/union under vessel (special tool needed?)
Lift out from top - hopefully
refit being opposite, have I missed something? If it has to come off the wall a pro is needed
