Given what you say above about what does that say about where you
should ideally apply the pipe clamps under the bath/sink taps: above
or below the isolation valve, which we have to assume may also be a
"horrible mix of boss white, hemp, PTFE and fibre washers in the way
of sound electrical connection"!? Should it be above them to ensure
hopefully the taps are at equal potential? (But aren't the taps'
electrical continuity also still likely to be compromised by PTFE
etc??) Bit confused!


I'd go for below. If you bond the two pipes together (and the bath if
it's metal) then there isn't going to be a voltage difference appearing
between the taps, even if the electrical path through the tap connectors
is somewhat resistive.

Cheers, Andy: done.
