Stoptap stuck after turning off!

[Andy1600]

Morning,

I had a call yesterday from a colleague who said that after turning off the water the tap jammed and could not open back up. By all accounts the Stop tap closed fine and the spindle turned easily whilst turning the water off.
Does anyone know what would have caused this?
Thanks

Andy

I had one like that last thing i done was turn water on then go home
in the end had to lift floor and chop wall out got jamed inside but spindle worked ok.

The thread has jumped either down to a weak stoptap and a piece snapped off or the washer has gone and it’s been threaded off sometimes if you tap the side while slowly opening it will work
