Hi I have installed a new shower, consisting of a mixer and rain head. As I live in a bungalow, there is not a lot of pressure, so I have installed a dual, hot and cold shower pump. But although the shower pump runs ok, and I do get pumped hot and cold water, I cant get it to mix properly.
I turn it full to cold, and I get cold, I turn it to hot, and I get hot, but I do get anything imbetween. i turn the mixer very slowly, and depending on which end of the range I start with, it stays boiling hot, or freezing cold, all through the range, until it finishes at the opposite end.
No way can i get a happy temperature in the middle, whatever I do. Can anyone suggest what I can do.
There may now be too much pressure in the system overall or to one of the feeds e.g. too much hot pressure, too much cold pressure, worth checking how much there is in the system and also the operating pressures for the mixer itself
