We have a pumped shower with a thermostatically controlled mixer valve. My wife complains that when she is having a long shower (hair wash etc) the shower runs at the right temperature for much of the time but suddenly changes to run cold, usually during the hair rinse time, for no apparent reason. This never occurs while I am under the shower, but I am relatively quick.
I can confirm that the reason is not lack of hot water in the tank. The shower pump is at least 16 years old. The mixer is not as old but may be 8 years or so.
Can anyone advise me please of the likely cause of the problem.
