Hi folks. Have replumbed my house and it's just occured to me that I didn't remove any earth bonding when I removed the old plumbing, and totally forgot about installing it with the new.
A quick check in the cupboard under the stairs and sure enough the only 3 cables going to the earth block are all 6mm, 1 goes to the earth, one to the CU and one to the economy 7 CU. Nothing goes to the plumbing.
It's a TNS system.
Looking at the earth block, I wont get bigger than a 6mm cable in there.
I have a plastic watermain coming into the kitchen then it converts to 22mm copper.
Bearing in mind that the main earth cable clamped to the earth is only 6mm, can I use 6mm earth cable for my main bonding?
Does the length of the cable run affect things? The easiest route for me to run the cable would be to have one end clamped to the 22mm pipe (just after it converts from the plastic water main), then running up the wall, under the 1st floor floorboards then down into the understairs cupboard, into the earth block. But if I ran it round the edge of the downstairs rooms and through various walls, I could cut 4meters off of the length (although would have to drill some long holes).
The bathroom has a non electric shower (no shower pump etc) and a sink (no bath). I presume (looking at various web pages) I need to supplimemtary bond the 2 pipes supplying the shower and the 2 supplying the sink together?
99% of the plumbing is soldered, but due to a last minute change of plan, I have got one of those push fit copper fittings in one place. Anyone know if I need to bond eitherside of this together or whether the copper push fits don't need bonding.
Sorry for all the questions.
Thanks
Phil
