I'm not a plumber, but I have spent the last 4 days watching a mate of a mate (who is a plumber), fit my new bathroom suite..........so bear with me please.
There is a short length of pipe that connects my cold water bath tap (gravity fed system, not mains) to a stopcock isolation valve. This copper pipe can be bent by hand as most of the length of it is ribbed. The tap, copper pipe and stopcock are all brand new.
When the plumber left at 6pm tonight, there were no leaks. In fact, he completed the bath fittings yesterday and the stopcock has been open all this time with no leaks. Well actually there was one leak when he first connected it but he fixed that one at the time.
However, at 9pm tonight, I noticed a few drips coming from the kitchen ceiling which is directly under my bathroom. I ran upstairs to find a leak in the compression joint that connects the 22mm copper pipe to the stopcock. It wasn't just dripping it was more of a gentle stream.
I switched off the stopcock and the leak stopped. It then started to drip, so I figured it was the existing water in the pipe, so I opened the tap to release the vacumn and the drips got faster until they stopped a short while later.
So my question is why would a compression joint that was working with no leaks suddenly start leaking many hours later ?
Was it not tight enough ?
Was it too tight ?
If it was too tight, can it be fixed by just fitting a new olive ?
Or do I have to replace the full section of bendy copper pipe in case it has a kink in it ?
Any advice welcome.
Thanks
Gav.
