I am refitting a washhand basin and pedestal and have a couple of flexible tap

feeds up through the floor or through the wall the basin is secured to .I'm
trying to either hide the feeds as much as possible ( using plastic ) or I'll
use chrome pipe,in which case it doesnt matter so much .
Are there "rules " about using flexible tails as keeping them straight as much
as possible or is it OK to "bend" them ?

Bring the pipework up inside the pedestal, that's what it's
for. This is one job where a bending spring can be handy to
get nice graceful curves. "Flexible tails" look horrible.
