Hi,
My folks have a Mira sport shower which is about 7-8 years old which has developed a problem.
The only way of turning the water flow off from the shower is by turning the dial on the shower unit that controls the temp until it closes this valve.
This wasn't always the case.
Previously the flow could be turned off by pulling the pull cord mounted to the ceiling.
I think the problem could be a fail-close valve which has become stuck in an open position, or maybe there is a flow switch that is defective.
Anyway I had a quick look at the unit and was unable to see and valves/sensors.
Any advice would be appreciated.
The unit is not a pumped shower.
Bob
