It's 20 thread. You can get brass end feed adaptors from merchants in Loughborough area. Come across it often in the Loughborough area, good for weighing in!

Asking out of the interest of lazy plumbers who charge too much everywhere, wouldn't a philmac sort this?

Possibly but they are too large to use in a lot of situations and look horrendous if on show. You've also got the bonding issue with a plastic fitting in copper pipe.
Im sure you are allowed a certain length of plastic pipe depending on the size, 15mm I think you can have up to 1m without it affecting the bonding as it is deemed the water will carry the current for that distance or something like that. I cant remember the exact figures but I know one plastic fitting wont affect anything.

You'd best let the institute of electrical engineers that then because I've got a paper from them somewhere about earth bonding and plastic pipe which states that water is too poor a conductor to act as an earth. Even if it did what would happen if the water was turned off and a fault developed?
I don't know where you got that snippet of information from but I would totally disregard it.

It is a technical update from British Gas, so I am sure they have researched it enough to deem it safe. Water is a poor conductor thats why the length of pipe is important and I cannot remember the lengths. They arent going to send their engineers out to work to their techincal operation procedures which could leave them open to be sued.
