According to our Surveyor, the Y-Valves needed some "exercising".
So I went about "exercising" them and you guessed it, I broke one of the handles.
Fortunately I was able pull one off another valve to get it to close properly again, and there was no damage to the valve itself.
What's the chances of obtaining a replacement handle?
I've been looking online and haven't found anything yet.
It's a Bosworth, but not sure of the model number.
I'm guessing they're the original 1985 parts.
Here's one of the good ones.
(And yes, I've been reading the hose clamp posts of recent)
