I have a problem with the Bath/Shower mixer taps in both my ensuite and main bathroom. These are 4 years old, fitted to a new house by Westbury.
They are both the same model and look something like this
They are now both spontaneously switching to the shower setting as soon as the water is turned on, and will not stay on bath setting when reset manually.
Anyone got any idea what is going on here?
thanks in advance Martin
