Just come back from a call out, Under the sink the hot tap plastic iso valve had blown apart, its only about 2 years old and its a John Guest, these are normally good quality and are guaranteed for 25 years, So i said ring the builder who had the kitchen fitted, ask where he got the fitting and produce the offending valve, I charged £100 for the call out so you could claim that back plus inconvienance, Its luck you was in and heard the hissing and acted according, If you'd have been out, or away for a week, it would have been devastating,  |

I can only think that it was mistreated somehow, I've never seen a JG blown apart before, Being under the sink I don't think the cold spell had anything to do with it, It was a clean break across the valve body, no signs of scratches anywhere and it was totally free to move about, it was connected to a tap flexi, A complete mystery,  |

Tom Did it split through a mould line as this would be the weakest point if any !!!!

Tom Split on mould line usually means the fitting was sub standard when made ..... moulding was not upto heat / pressure in the mould when made
back to JG for compo me thinks !!!!!!!!!

As it happens, I've just got back from a call out to a plastic stop valve. Got the call at 9:45, water's coming down the walls, told her to turn water off at mains and I'll be there in 20 mins. After telling me where the leak was I guessed it was coming from under a bath on the 2nd floor, took the panel off, asked her to put water back on for 5 seconds and woosh, properly pissing out from under the valve handle. Replaced it with a speedfit coupler and got back home a little wealthier. Here's the offending stop tap. Attachment DeletedAttachment DeletedAttachment Deleted |

The only brand name on there is Opella, I thought they just made crap fill valves, seems they also make crap pushfit valves too.
Looks exactly like a JG tap except the bits that connect to the pipe were exactly like poly plumb fittings, you know the ones that leave bits behind on the pipe when you take them off cos they only slide one way.

"Opella" is a name that I can remember from my apprenticeship days 72/75.
The taps looked just like the ones in your picture JC!
No push fit's though, back then they were all compression joints.
They wasn't cheap either, very fashionable (sink taps) in the early 70s and they seemed to me to be of a good quality plastic.
Water heaters too often had "Opella" taps on them.

I can only think of 2 push fit fails - neither being a fault of the p/f fitting.
The first one was a call out to a fitted that day sink.
What had happened was has the plumber tightened up the tap connection he didn't notice that the flexi tap connector was actually unscrewing itself from the pipework at the other end of the flexi.
It actually held by half a thread until the night time when it shot off due to the increased night time water pressure!
The 2nd one was of my own doing.
After soldering some stabs in my rush rush busy busy days I simply didn't give the pipe long enough to cool down and pushed the fittings onto the copper pipe whilst the pipe was still warm.
It held just long enough for me to get upstairs to check them, when whoosh the cold water one shot off, followed by the H/W one a second afterwards!!
A definite quick quick, panic, panic, moment!
