Unvented hot water expantion vessel!

[benny_headland]

Visited property 10 months ago as expantion vessel had pin holed and started weeping , cylinder was about 4-5 years , we changed the expantion vessel for a new one and now that one has also pin holed? Can any one suggest a reason for this happening? Chers

Atlantis heating.

Presumably there's inhibitor in the system?

Are the radiators old or corroded? Possibly metal parts flying around the water works?

Sorry its the hot water expantion vessel , not the central heating side.

Was the replacement a red expansion vessel. It should of been blue or white

 

[benny_headland]

Yes the replacement was a white one!
