how can i rectify the shower mixer temp problem?

Hi Keith, thanks for the prompt reply, the shower is located in a static caravan on a campsite in Spain. the cold water mains is quite powerful, the heated water is via a combi boiler, when the hot tap is turned on at the sink it takes a while for the hot water to reach the tap and its not as strong a jet as the cold water. would it help to turn down the cold water pressure at the stop tap ?

Hi Dave, Check all the usual simple suspects first, supply valves fully open, none of the filters blocked etc and then consider the following :-
You say the supply temp is very hot and the same thing happened with the previous shower, are you sure you are not 'cooking' the cartridge ? (65 degrees) is the limit, if this is a problem the 'anti scald control' maybe trying to close down the shower. Finally is there too much of a differential in the pressure between the hot and the cold ??
