It's very dusty up there, and I have to wear a proper filter mask. As I
was returning the mask to the garage area below the living area of the house, where I keep such things, I heard a noise coming from the hot
water tank. Turned out there was a leak from where the heating element
goes in. Given that the tank is under pressure, the leak was making a hissing noise.

The problem started with the appearance of dust and grit falling into
the bath. It was not at all obvious where it was coming from. With
showers being preferred, the bath is little used, so this wasn't coming
from the taps. I climbed into the roof space above the bathroom, but
nothing was apparently amiss.
In the roof space there is an old tank, which I surmise was once the hot water tank. It has long been unused, and was presumably left there
because it would be difficult to remove, and there was no compelling
reason to do so. There is also some pipework that I had originally
presumed was unused.

Now, some years ago, I tried to trace the origin of the water-hammer
noise, searching under the house without success.
My visit to the roof space made me wonder whether that pipe was really unused. Indeed it appears to have been sealed off. I now think that one
part of it goes down the wall into the garage area to join the hot water output, with the other part heading down to the laundry. And where it
goes down the wall is close to where the dust and grit is falling into
the bath.
All of which makes me think that the dust and grit in the bath and the
leak in the hot water tank are not unrelated. My theory is that this is
the pipe that makes the water-hammer noise, given that it's not well attached to the framework, and that the tank leak changed the hammer
pattern enough for the pipe to disturb different dust/grit in the roof
space which is then able to enter the bathroom through a small gap in
the ceiling trim.
On one level, this seems rather far-fetched. Yet the coincidence in
timing is remarkable.

The tank shouldn't be under any pressure at all if it's not being used.

If you do, then the supply and feed pipes to this old lump should have
been cut and capped off....

The tank in the garage is the current hot water storage tank/heater.
