Double Check Valve with isolator?

[Triumph1]

Does anyone know where I can get a DCV with an isolator that is WRAS approved?

I need one for an outside tap and have limited space so I could do with a combined item

thank you

Filling loop and bin the loop you can use nuts both sides etc

Eg R24 Filling Loop - Screwfix - https://www.NoLinkingToThis/p/r24-filling-loop/83905

As above, or swap out the outside tap for one with a double check valve built in.
