combi system re-pressurisation

[fender]

Hello guys,

Just out of interest, is there any kind of rule as to how many times a combi system can be re-filled b4 the expansion vessel requires re-pressurising?
Or, are there any faults in particular that cause the need for a re-pressurisation?

Cheers

General fault is split or holed diaphragm.

Have you looked in the sticky

Thanks clf,

I did look, but it didn't quite answer my question.

What I meant was, how many times could you do a drain down and re-fill before doing a re-pressurisation. Or, is it only an actual fault that will make a re-pressurisation necessary?

Cheers

As long as the diaphragm and valve is good you could do it every day if you so wished
