whats th differnce? Which do i need for copper piped CH?

thanks, NT-

I didn't use any goo for my CH and it never leaks. Only problem

arises

with
scratched olives and/or copper pipes.

I use jet blue from plumb centre 'cause it's good for gas and also
potable water.

Some people wrap a turn of ptfe around an olive.

I never trust a com,pression fitting. Only use them where

manufacturer

has provided them and there is no other way of connecting to their
appliance. Never use them by choice.

They use them a lot on board ship and never use a compound, but they
also get a lot of leaks which they don't give a toss about. Youve got
decorating and carpets to think about.

OK, I'm undoing joints made with hemp and gloop, and reassembling, so I
assume I shall need gloop. I just dont know which gloop. I dont have
any hemp btw

Available from any street corner dealre,but you will have to go to a
builders merchant for plumbers mait.

thanks, NT

Well traditionally we used hemp and boss white. A gromet made from this was far superior to a fibre washer in a tap connector for instance. But we aren't meant to use it any more, particularly boss white, but I don't think we should be using hemp on potable water either. I have found that a similar gromet made from ptfe alone works very well, and is also far superior to modern production fibre washers which are not to be trusted.

For gloop, read boss white, but not in the case of potable water in which case the best alternative I have found is as I said Jet Blue.
