kitchen mixer tap check valve

We always get non body tap mixers

Kitchen sink is a cat 5 fluid risk so must have an air gap present. So if no instructions then a single check valve on both hot and cold as the only contamination can come from hot water into the cold water mains. Hot water being a cat 2 fluid risk.

Yes, and so long as the tap has the required air gap as per JCS post.
