15mm fitting won't fit (what is table Z)

[ottosump]

Hi group, I have an outside tap with copper pipe running through the garage, a section of the 15mm pipe in the garage had been replaced with beer house (approx 6 inch) the last cold spell we had this failed and flooded the place. I thought it would be a simple fix with a flexible 15mm connector, however the 15mm pipe which stems from the ground will not fit into any 15mm fitting I have. I cut a couple of inches of the pipe away and went to my local plumb centre, I was told it was and old ‘Table Z pipe’ I think he said, and it was quite difficult to get parts for. The walls of the pipe do look a lot thicker than standard copper tubing. My question is, can I get a fitting to reduce this to standard 15mm (the adjoining pipe is 15mm standard)

Thanks group

Oh, the property is approx. 75yrs old...

They are solder fittings. standard 15mm compression or solder fittings need the old pipe outside diameter reduced to fit

As a diyer you may find a universal transition coupling is the easiest thing to use. Have a Google as there are various sizes and outlet sizes tend to be larger for joining to plastic water main pipe but you can get a 15-21mm x 15-21mm. No real plumbing skills required to fit them.

Quick update, managed to make the connection with the aid of a swaging tool, cost about £65 but I'm sure I'll get more use from it. Had a couple of failures initially (see photos) on cold pipe, found if pipe was heated and tool rotated that it helped, anyways fluxed, soldered & tested, happy chappy.
Thanks for all the advice guys, much appreciated.

That's a good tool and an investment, offset against the cost of a plumber

For future reference, the straight pipe is supplied half-hard. If you heat the end red hot and quench it, it will anneal it and make it soft and pliable. You could literally squash it with your fingers. It will then strech more easily without cracking. It work hardens as you manipulate it, so you may need to anneal it again if you're bending it a lot.

Think of the money you will now save not having to buy any more couplers!
