Separate outlet mixer strongly preferred for kitchen sinks and other
potable water applications. The concentric outlet type with the cold
wired to the outer also helps keep the spout cool to touch.

The diagram of the tap included in the 'instructions' shows 2 separate
channels with it being open at the spout before going into the 'flow
straightener' (weird name!)

Can you take the piece of black plastic off the spout? If you can
then can you see two water channels in the spout? If you can then I
don't see that a check valve is needed.
