Quick main bonding Q

Hi there,

Gas meter is exernal and pipe enters property under suspended floor, where it stays until well after its first branch. I can bond where it enters the property as I'm told I should by the regs (and this is also just within 600mm of the meter for what it's worth) but of course that'll be under the floor. Is a floorboard inspection hatch sufficient that the bonding connection can be considered accessible for inspection/maintenance? i.e. what's least bad - accessability requiring a slight carpet corner peel, or ignoring "...or at the point of entry to the building if the meter is external" and extending my equipotential zone outside the building into the meter enclosure?

Similarly, my water incomer is lead - mmmm. Only for about 18" before it becomes a full plastic installation, but I assume I still must main bond the lead bit. Again all under the timber floor, but this can be made slightly more accessable with a hatch in the base of a kitchen cupboard - no carpet to peel.

Advice appreciated as always,

Liam

As far as i can see you should be ok as you suggest.

if it's under the floor then it hasn't entered the building yet has it?

odds are that you won't be able to touch that pipe in every day use..?

Hmmmm. Well it's within the walls - just beneath the floor boards. Personally I'd classify that as having entered the building! Where it first becomes visible above floorboard level - pretty much a tie between the boiler and cooker supplies - is well after branches in the pipe. You wouldn't be able to touch the pipes in everyday use, no, but as far as I'm aware that doesn't exempt them from requiring to be main bonded, does it?

Cheers,

Liam

You may have a more serious problems.

Gas pipes should not be run beneath floors due to the risk of a gas leak and subsequent explosion. You should be thinking of rerouting the pipe.

Eh.
Surely running under the floor is ok in a ventilated floor space.

Hmmm not heard that one before myself, and I did live on the plumbing section for a while before I came over here. Mr Corgi didn't bat an eyelid when he sorted the gas either.

Cheers anyway.
