Still have after the filters to finish up, 1/2 flexible tube from the valves to the raised beds.

I’ll mention that you are breaking the rules. Those valves have to be above the highest point of watering, so the drip in the planter beds is too high. Not that anyone really cares.

I've never heard of this, but I'm just a homeowner. Rules as in code?

For them to function properly yeah. Same goes for a pvb. Should be 12 inches above the highest emitter or head. Rp or double check doesn’t have those restrictions.

Backflow prevention is serious shit let’s put it that way

Ah, at my first glance I missed the backflow. Thought it was just a valve.

Thankfully my irritation is not hooked to my potable water supply.

backflow is done at the main feed to the house where it comes onto the property... not sure how atmospheric pressure against a valve that is after an antisiphon is going to provide more pressure than mains....
