I thought about putting unions all over the place so that each

professionals use this approach, so I am guessing this is not a

In my building code, unions are only allowed "adjacent to accessible
equipment". That is, if you hard pipe an appliance, you can use a
union for the final connection. Otherwise, unions are out. You can
use a left/right coupling, though.
