Earthing Again
 

Do all fixed water appliances: boilers, cyinders with pumps on them and
the likes of, require a separate earth wire from the appliance back to
the meter earth terminal bar? Or will a wire from an earth tag to the
switch be enough? What if the appliance has mainly plastic piping
connected to it?

TIA

no

yes, unless in a bathroom or other location where equipotential
bonding is required

it still has to be earthed in accordance with the manufacturers'
instructions.
