Hi all

Got a PME with 6mm gas & water
Looking into the board there is 10mm gas & water it's been upgraded to 10mm.

The 6mm from the PME is still in place with the 10mm. Board was upgraded to an RCBO board. What would you do?

I have a pic

Cheers

Do you mean there is 10mm in parallel with old 6mm to both water and gas?

I would just leave it be, unless you suspect the 6mm is a much shorter route than the new 10mm and so might take the majority of fault current.
