Hello
I've got a Bristan Prism Thermostatic bar shower, pumped from my hot water cylinder.
Water is coming out coldish regardless of thermostat position. There is plenty of hot water in the tank and the hot feed at the back of the mixer gets hot.
I think there might be an air lock as there is an audible noise such as when a radiator needs bleeding.
Any ideas what I should try?
I've found an exploded drawing online but no manual.
I'm not sure what the dome in the middle is for (perhaps it is for bleeding) but on my one there is no obvious way of removing it if indeed that is what it is for.
