What type of backflow prevention do you guys use for these?

We use pressure type vacuum breakers here.

Me too. We use the 3-way type. The middle leg faces down and drips when the side legs flow thru. There are 2 slats on the side of the drip chamber that function as an air gap for the middle drain leg.
