hi, does anybody know if i have to replace the whole cartridge or just change the o'rings on the original cartridge for the vaillant ecotec pro 28.
if i can get away with the o'rings do you know what size they are?

many thanks............phil
 
Does anybody know if a non gas safe registered person is allowed to do this? 😳
I would say that you should be GSR. If you are GSR then let one of the mods know and they will give you access to the area you need. If not get yourself a GSR in to do the work.
 
And you have not got to do the whole process again once the diverter packs in completely.
