I have a Mira Extra Bath & Thermostatic Shower Control run from a Combi boiler. I noted that the hot water from the tap was cooler than expected.
I isolated the hot supply thinking to look inside but, on checking that the isolation was complete by opening the tap, I saw (and felt) that cold water was coming from the spout. The cold tap was turned firmly off at the time but cold water was coming from somewhere so I assume that the tap was not seating properly. This is obvioiusly the reason for cooler hot water than expected.
I'm confused because I'd have thought that if the tap wasn't seating correctly it would pass all the time but with hot and cold taps turned off, no water passes to the spout.
Mira suggest a visit from an engineer at £139. I'm hoping that a helpful soul on this forum might point me in a better (and cheaper) direction.
Many thanks
Dave
