Hi, I would be very grateful for some advice. The hot water in my shower went cool a couple of weeks ago. When I remove the shower head the water is considerably hotter but nothing like as hot as the water that comes from the bathroom taps. Additionally, though the bath water is hot the flow is poor. Flow hasn't always been poor in the bathroom I've just noticed it now really when my dad came over to look at the shower for me. I have a baxi maxflow wm combi boiler. Many thanks
