Got new tap, swivel-spout mixer, with the usual metal mesh outer. Now, a
couple of things:

how durable are these tails? Pressure is about 4 Bar, so quite a force on
the hose.

the tails have 10mm thread into the tap, with a little O-ring as a seal. If
I tighten a tail as much as I can I can still unscrew it by just twisting
the other end. The hex on the tail is no good as it's deep within the base
of the tap.

As the water supply is in Speedfit and tails end in 15mm female I'm getting
a pair of Hep2O push-fit tails.

For fitting the waste I have Pluumbers Mait; not a fan as it sticks to
everything except the right place. Is there anything better?
