Is there not
a type of compression fitting that can release pressure in the event of a freeze?

Will plastic pipe rupture if I replaced the outdoor copper? Mind you, it won't solve the problem of the washing machine breaking.

cos of the difference in expansion co-efficients of brass and copper...
i've come across a number of compression fittings that have simply slipped off the end of the tube, leaving the circular marks where the olive was once firmly attached.
hep2o and suchlike seem more burst resistant, my personal choice is 16mm mlcp which is poly-ethylene and aluminium.
yeah, wouldn't have saved the washing machine.
anyway, duty calls...
