My son has a tap in his garden that feeds a vertical fairly thick walled
rubbery plastic pipe to a right angle connector. From there water was
fed via buried rubbery pipe to 3 taps located at various quite long
distances around the garden.

Last Winter in the frost, the rubber pipe to connector started leaking
and produced a huge ice sculpture.

As a temporary bodge, I stuck a bar from a socket set in the end of the
tube and held it there with a clip. It looked as though the inside of
the connector was smooth and the rubbery pipe had been glued into place.
There was no sign of anything looking like an olive.

I took some measurements and visited a couple of usually good merchants
looking to buy some sort of connection arrangement, but only got talk
like "that's imperial, haven't seen anything like that for years". They
also said that any glue they sold would be useless because it would
either not work or dissolve the plastic.

I've put some pics that might be visible at

Any simple low-cost suggestions? I know I should have measured the pipe
again before writing this, but forgot. It's about an inch od.

Try an agricultural supplier, there are plenty of farms with imperial
pipework in place.
