Keep it tight and use this, for best job ever.

Agreed, still needs to be sleeved though.

I use a 16mm bit first followed by a 20mm bit and insert 20mm electrical conduit which the 15mm copper glides through:

neat keefy, why sleeve it alot folk do and dont some time i do some i dont,

 

[helpsy]

I use a 24x1000 bit available from Toolstation .

I use this too & also as said the 24mm x1000mm bit from stoolstation. Again also sleeve it, preferably in plastic. Makes for easier removal & stops the copper pipe corroding IMO.

why sleeve it

Because this diagram says it should be:

DCV fitted inside ?

Ahh you beat me to it Keefy !

DCV fitted inside ?

Of course - iso' and a drain cock too in cases where the pipe has to come into the tap from below.

Edit: Thought you were asking if that tap of mine had one fitted but if you're wondering why the diagram shows a DCV on the inside that's because the ones built into the taps are susceptible to freezing so you're now required to fit them inside the buildings envelope. Taps that incorporate an in-built check valve should now only be fitted as replacements or suitably protected from the elements.

my only issue is that you cant drain the water out over the winter if you pipe it upto the tap

 

[smtplumbing]

i run my pipework right that, to allow the water to stop freezing

 

[hammers4spanner]

sleeve or tape tho imho

just helps stop any possible corrosive activity

Which is why I fit a drain cock too.
