Hi Bob, sorry for the delay in responding.
There a range of different models for your brand of shower, to confirm your setting the temp dial on the shower, then the following day go to turn the shower on and the dial is still set to the same position but the water is a different temperature?
Good morning do you still require assistance?
I havent heard back from you in a while, do you still require assistance?
Good morning Bob, I havent heard from you in the last couple of days do you still require assistance.
