Outside tap instalation

[rpm]

Needs a double check valve inline whether there's one in the tap or not

Have to admit this has always puzzled me, could you explain why if I ask nicely.

I believe it's because the tap has the potential to be changed to one without in the future

That's what I thought 20m is one hell of a house never mind a 20m posh caravan lol

I was under the impression it was also because if a tap with check valve is fitted but the supply is left on over winter the check valve can be damaged by frost

That's how its shown in the water regs book,
But what if the tap is changed in the future
The in tap dcv can be damaged by frost
Also those taps are made to be fitted when a outside tap is replaced that has no dcv inside
