Ideal mini bath deck mixer

[Jolead]

Evening

I'll go straight to it....

Ideal mini combi and non thermostat bath shower mixer.

Run the hot tap on the mixer boiler fires water stays same temp for 5 mins.

Move divertor to shower fully hot boiler fires. Then try to add some cold the boiler cuts off.

I then fitted a new thermostatic shower mixer which initially worked fine. Now its doing the same thing.

Does anyone have any ideas.

Many thanks

Hot and cold the same pressures ?

Hi

It's a combi boiler so yes. Unless there is a pressure reducing valve that I haven't seen somewhere......
