I’ve just had a mixer shower fitted, taking hot water from a Combi boiler.
When I turn on the shower the water flow is constant but as it heats up and once it’s warm the flow of water starts to fluctuate (pump), high pressure, low pressure, high pressure, low pressure, etc, it changes every second or even less than second.
When I run hot water in the kitchen or in bathroom bath or sink then the water flow appears constant.
Ay ideas what could be causing this / how to fix it?
Thanks.
