Where Is Adjustment for Apollo (Conbraco) Series 35 WPRVs?
The literature for the water pressure regulating valve states it is adjustable but I cannot find any screw or locknut. How does one adjust this valve? It currently only provides 5 psi, I want it up to about 12 to 15 psi.

Yes, when I open it. What I mean is, if I leave the supply valve open, it applies full house pressurei to the system. I can override the regulator valve for a "fast fill" and get the system pressure up to about 15, but then the backflow preventer valve opens.
When the system is closed up and in its operating condition, the pressure slowly builds up (over 1/2 hour or so) to about 10 psi. Then the backflow preventer valve opens a bit and water dribbles out the vent pipe. The only way I can stop the drip is to turn the supply valve off.
So that's the way I've left it. Have to get another backflow valve I suppose.
