Could it be 1/2" rather than 15mm? If so, it would be
*slightly* bigger than 15mm and, with a bit of surface corrosion on top, it
may be difficult to get a 15mm fitting over it. How have you cut out the
damaged section? Have you left any burrs at the end of the pipe - because
these, too, would stop an olive from going on easily.


No, it's definitely 15mm, or was!

I cut it with one of those pipe slices like this:

so there were no burrs. It wasn't just the olive, I couldn't get the
nut or the fitting on either.

By the way, how long should these pipe cutters last? I bought a Hilmor
one from B&Q a few years ago but the metal rollers rusted and seized
from getting wet in use.

I'm on my second now but I've noticed recently that sometimes the
cutter slips and it engraves a "corkscrew" on the pipe rather than
cutting it. I never had this with the first one. I changed the blade
but even with a new one it sometimes does this. I notice there is an
arrow on the body and I think this happens when you turn it against
the arrow.
