Very much, suddenly.

Hi,

Only thing I can think of is either some debris like PTFE tape has
blocked the cold inlet, or a lump of loose scale has got stuck in the
valve.

With gradual scale buildup I'd expect it to have increasing trouble
holding the set temperature,

cheers,
Pete.


When I first installed it I was far too heavy with the wrenches and when I
disassembled
last month I saw that the filter washer was crushed and probably allowed who
knows what..
perhaps even a piece of the filter washer mesh.
I currently have the shower body disconnected from the inlets so I think
I'll let the water through for a minute and watch if something is flushed
out.
If nothing shows I will have to send a photo of the thermostat to the
showerdoctor.
