Connecting 22mm pipe to old stop cock
I need to replace a section of 3/4" copper pipe with 22mm. Can I
connect the new 22mm pipe to the old stopcock where the 3/4" pipe was originally connected? Will a standard 22mm olive do the trick? I assume I'll need to find a different nut from another 22mm fitting. Thanks, Dave. |

This is a special adapting olive to get you from 3/4 fiting to 22mm pipe. Proper plumpers merchands are your best bet, I doubt the large diy chains will know what you are talking about. Cheers |

Or obtain a special olive for just this purpose. The first way might be easier in practice, though. -- *A plateau is a high form of flattery* Dave Plowman London SW To e-mail, change noise into sound. |

The porky olive should do it, although I have successfully made joints to old pipe using ordinary 22mm olives and tightening them more than usual. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Cheers I've only encountered special olives to fit a modern 22mm fitting onto an old 3/4" pipe. The OP wants to put a 22mm pipe into an old (3/4") fitting. I think he has to have a bit of 3/4" pipe in the old tap and then convert to 22mm using modern 22mm fitting with a special olive. Will a 22mm pipe actually fit into a 3/4" compression fitting?

In an earlier contribution to this discussion,

Err . . . 22mm pipe actually has a *larger* OD than 3/4" pipe - which is why you need a 'fat' olive when using 3/4" pipe in a 22mm fitting. 22mm pipe (with a 22mm olive, of course) *might* go into a 3/4" fitting - but it would be a tight fit. As others have suggested, a short length of 3/4" pipe may be needed, followed by a 22mm coupler with a fat olive on the 3/4" side. [Or you can get solder couplers which are 3/4" one end and 22mm the other]. -- Cheers, Roger ______ Email address maintained for newsgroup use only, and not regularly monitored..
