Hi

I live in Northolt in West London. There's usually no problem with
limescale or anything around here, but in recent weeks the water
coming from the hot tap is cloudy. The drinking water is fine.

Any ideas what might be causing this? Is the source the same for the
drinking water and boiler? If this is too difficult to diagnose, what
should I get a plumber to look at.

Any help you can give me, I'll be eternally grateful for

thanks

David
