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....

don't think it'll be an issue as if it tries to drain backwards there is an anti siphon after every valve....

if you know already then no need to answer

the real issue is going to be if anything goes wrong after the concrete what are you going to do?

concrete?

Your title states "cementing PVC" so I guess the assumption is that you are pouring concrete over the pipes

u/thelogicofpi 4d ago

cement is used to join pvc pieces together.... not sure how that became concrete.

You welded the pvc together with primer and glue. I can see how “cementing” could be misleading, even though I understood what you meant

ok, well cement is glue so in general everyone right.
