Personally, I prefer Boss White and hemp over PTFE tape for joints where

But for the record, I have to interject with "not on potable systems".
It's OK for heating - but the hemp itself has been regulated away as a
breeding ground for bugs.


Is that an EU regulation - which we will be able to dump post-Brexit?

Seriously though, whilst you *could* drink water from outside taps, most
people use them for garden hoses or car washing - so this wouldn't be an
issue in practice. If it *is*, stick a "Not Drinking Water" notice on the
tap.

Makes a lot more sense to use PTFE tape instead.
