No person shall install any installation pipework in any position in which it cannot be used with safety having regard to the position of other pipes, pipe supports, drains, sewers, cables, conduits & electrical apparatus & to any parts of the structure of any premises in which it is installed which might affect it`s safe use.
(Enclosed pipes)..........No person shall install any part of any installation pipework in a wall or a floor or standing of solid construction, unless it is so constructed & installed as to be protected against failure caused by the movement of the wall, floor or the standing as the case may be.
No person shall install any installation pipework so as to pass through a wall or a floor or standing of solid concrete construction ( wether or not it contains any cavity) from one side to the other unless:
any part of the pipe within such a wall, floor or standing as the case may be takes the shortest practicable route & adequate means are provided to prevent, as far as is reasonably practical, any escape of gas from the pipework passing through the wall, floor or standing from entering any cavity in the wall, floor or standing.
Where any installation pipework is not itself contained in a ventilated duct, no person shall install any installation pipework in any shaft, duct or void which is not adequately ventilated.
If the plumber installing your water pipes has taken the above into consideration, then to be honest..... I can`t see there being a problem....
