Hello
I have moved in with my girlfriend who's house is about 3 years old
She has the shower handle type which is one shower handle that swivels from left to right for hold and cold
Issue we have had for a while now is, you put it hot, and then overtime it goes really cold by itself
then you put turn it a fraction to hot, and then its blasts out steaming hot scalding water!
Its so sensitive and you can never get the temperature right!
its solar hot water, and a friend said to call them water people who installed it as it should be under warranty
Is there anything I can try out myself or anyone know what it might be?
