Do you know why?
I was wondering if the leak was from there as I damaged one of the O rings. Not having a replacement, I cut one from something, can't remember what...a piece of hose or something..?
It has been fine – hasn't leaked. Today, as it happens, I bought packets of assorted small O rings in a plumbing dept, in case of future need.
That could be the simple fix required?
Replacing a whole line seems a bit drastic?
