The Y-joint is a non-return-valve,which is a sort of miniature rubber membrane which only allows one way flow.
When they fail- They seem to just leak out of themselves.
It's a part which is very hard to buy a good one of, although Halfords do do one.
I think I may have replaced with a straight T-junction
Think I've got a picture of the alarm exterior part which you describe on the 146... (Before & after cleanup)
I also have a sort of air vent round the back of the car, with like a plastic 'sink strainer' over the hole.

On the Y-piece - no point in attempting a repair, by the sound of things - so I'll go straight for a replacement!
In fact: just ordered one here:
