I have been advised not to install natural gas as the pipes under the floor are copper and may not withstand the pressure if the bolts are not tightened enough. This problem arises as the screws were not tightened enough at the back of 2 showers and in the kitchen also. To put right this resulted in replacement of all items. In the kitchen the floors had to be replaced. It was major work. Is there any other way round installing gas without having to go under floors. My floors are concrete. Many thanks
