Today I had a flood in the bathroom. A compression joint connecting the copper pipe work to a short length of plastic pipe to the digital shower mixer failed and being at mains pressure produced a spectacular fountain.
This joint was made mid December and has been fine ever since. The reason
for the short plastic pipe was due to the pipe clips I was using meant if I went copper up to the push fit connectors Mira have specified it would have resulted in an awkward little off-set so the plastic pipe solved that. I
have been scratching my head as to the cause why after 21/2 months?
At first I thought I may have omitted the insert but it was there, I did
note the olive did not seem to have bitten into the plastic as expected so there maybe the nut had not been fully tightened, but that usually results
in a weeping join.
I am a bit old school in that I prefer copper and soldered joins and compression fittings as necessary and have never felt 100% confident in plastic and push fit joins other than for low pressure waste pipe applications. Today’s experience has not improved my feelings about plastic pipe in mains pressure applications. It has left me wondering if it was
more an external issue namely a temporary spike in water pressure and it
just found the weakest point?
Anyway, I cannot say I feel confident in the repair and domestic management was not best pleased with the soaked towels and bedding, especially with
the stuff she had ironed only a couple of hours before.
Any opinions on the cause and suggested remedies would be appreciated.

Not sure of the cause - overtightened compression fitting maybe? I'd try a pushfit plastic connector - I've done a fair few plastic-copper connections using them.

did you put a pipe stiffener at *each* end of the plastic pipe?
And another cause can be incorrect pipe insertion depth into the
fitting, some plastic pipe have a repeating black line on the outside of
the pipe, the idea being you cut at one of the black lines, and then put
pipe stiffener on, then insert into fitting until you reach the 2nd
black line on the pipe......

As a few have said it must have been an under tightened nut as the olive
just slid off whereas previous compression joints to plastic have resulted
in secure olives that could not be removed. It just puzzled me that there
had been no weeping which is a common indication of an under tightened nut
or that it did not come apart on first pressurisation as we have quite considerable pressure on the mains.
Anyway SWAMBO has calmed down and the heat pump tumble dryer has beenProbably not a bad idea for peace of mind...
working overtime and stuff is going back in the airing cupboard. We are now worrying if it will happen again, I might put a pencil mark on the pipe and regularly observe it to see if any movement occurs.

John Unfortunetly I used the plain inserts which have always worked in the past.
As for push fit fittings I already had the compression fittings spare so simply used them as such joins always worked in the past. If it looks like the problem is likely to repeat using push fit will be an option.
