Hi, I will be doing some work in my parents bathroom soon, oddly they have a gas meter on a shelf in a cupboard in the bathroom. The cupboard is rotten from years of not having an extractor fan. The meter has solid pipe connected to it, not the flexi type. My question is, should this pipework support the gas meter for the short time it will take to rip out (carefully) the old cupboard and put a new one in its place? I don't need the meter moving. I just need to replace the shelf it's on and the cupboard it's built into? Any advice gratefully received!!
