Hi, for a few years I've once a month cleaned the small guaze filter on the Hot Water feed inside my Mira shower mixer, as it gets a build up of gunge and reduces the hot water coming out of the shower.
I've been told it's limescale in the copper hot water tank, which feeds the shower, and that I need to get a new tank. It's probably fairly old, 10 years or more.
Is this good advice. It also takes quite a while for the shower to get hot suggesting a restriced flow or lack of pressure. The tank is about 6m from the shower. Cold water side if ok (gravity fed).
