Does anyone recognise this push-fit elbow? They're about 3 years old according to my mum (whose house they're fitted in).
The collars on two of them have split and flooded the ground floor. They don't have a manufacturer stamped on them (the printed numbers on the brass are just a batch code and max water temperature) and I'm guessing the plumber who did the work used the cheapest ones he could source.
I've never seen this style before, and while I've suggested that she has a water hammer arrestor fitted to minimise further damage I'm sceptical about the others lasting much longer.
That looks more like a crimp-on style rather than push fit.

Osma Gold I believe.
Thanks Bear, that's the one. Seems to be no shortage of problems with them if Google is to be believed.
I wonder if these are the originals from when the house was built in the early 2000s and not recent at all.
