Getting a high pitched “ticking” noise ( I can’t hear it, but the wife can) from the motorised heating/water control valve. Is this normal?
As I typed this, I realised I can check it by turning off the hot water / heating one at a time and see if the telltale moves.
Answers would still be appreciated tho .
