what like?

 

[doyle]

same as last pic, no earth bonding and pipe no sleaved, electric cable wrapped behind pipes and fused switch to close to the pipes

ps even the little red light doesnt work on the fused switch how embarrasing

Doyle, there is no requirement for pipes under a boiler to be bonded together ( although I think its good practice if the boiler has plastic parts and does not give continuity between pipes ).

Which pipe do you mean is unsheathed? The gas is and the PRV vent does not need to be.

gas pipesleave not sealed on the inside. Get the installer cut off his head and stick it on a spike outside Basingstoke Towers as a warning to us all. (Unless it's through the wall into a meter box, which I guess it must be.)

paul, ever tried to get Transco to seal a sleeve where their pipe enters a building?

150 mm from a gas supply pipe!

well it is more than 150mm from gas pipe , its just next to the water pipe

 

[doyle]

yeah thats for gas what about building regs for electrical installations where no cable or joints are allowed below water systems or something or another which includes elecy cable below baths sinks and their pipes.

Quote the BS7671 reg then, probably find cables should be 25mm from pipes(water), socket outlets are advised not to be below sources of water unless the correct IP rating.
