Shower/Boiler problem?
I've just had a shower, water was slightly too hot to begin but a minute later water was icy cold, then too hot then back to icy cold again, never happened before. Is this a boiler problem or shower, would anyone know. No one else here who could be turning on taps, etc. Controls are inset into the wall. I never alter them as it is a lever, not manual and not worth the hassle. Thanks.
