I'm having a new gas boiler installed.
Currently, the gas meter is in the garage, and the new boiler will be
located in the house, in place of the old one .
The house & garage are seperated by a 3ft wide path.
The existing gas pipes (There are 3 x 15mm pipes, feeding the gas fire,
cooker, & existing boiler) running under the path between the garage & the
The plumber tells me the gas pipe between the garage & house has to be
replaced with 22mm pipe.
My questions are:
1) What precautions have to be taken when running pipes under the path,
should they be ran in some kind of protective ducting ?
2) Is it ok to use copper pipe, or should iron pipes be used ?
3) Will one 22mm pipe between the meter & the house be sufficient ?
(The existing pipes don't appear to be protected in any way, and I wan't to
make sure the plumber complies with the relevant regulation(s) )
