I have a shower with a Salamander Right RSP 45 pump which was installed about 10 years ago. When the thermostat is turned down (cold) the pump cuts out. Only way to get the temperature right is to let it run fully hot for a while and then very gradually turn it towards the cold. If I turn it slightly too fast it cuts out. Takes about 15 minutes to get it to the right temperature every time I shower!
Is this likely to be something I can adjust on the pump, or maybe a blockage in a filter somewhere?
