I had a major domestic crisis last week, when the bod who came to replace my gas meter condemned my pipes as too leaky. Soon resolved by a local fitter who replaced the sixty-odd year old iron pipes with new copper ones.
This left me wondering how much gas had been escaping. I forget the numbers but the manometer was dropping at about twice the allowed rate. Has anyone got any idea how this would relate to cubic feet, roughly? Obviously we're talking an order-of-magnitude guess here.
My gut feeling is that the loss was negligible, probably a lot less than the gas used by a pilot light, and so I won't be noticing any reduction in my bills.
