Long time no chat. Well, I'm back

As you may all remember, I installed a system myself in June/July. I have a PVB, inline valves, and the 2 valve boxes. 5 zone system, expandable to 6 zones if needed.



Next year I'm thinking of "re-doing" the valves/backflow area, as groundhogs and moles keep digging into the box, and around it, and chew on the wiring, and just make it a plain mess. We've always had a problem with these animals.



If I install Anti Siphon valves properly above ground (out of mole and groundhog reach), do I still need a PVB

Wow. Thats surprising considering the fact that they sell ASVs at HomeDepot, Lowe's, and even irrigation warehouses near me even though no-one can use them. My neighbors just had ASVs installed without a PVB, and that was done by an irrigation company. Some of the older systems still have ASVs or just inline valves with no backflow protection at all.



I will try again with boxes. The rodents kept pushing them up was my problem, which made a mess and broke the PVC manifold due to weight shift.



What if I was to use the ASVs and the PVB since I have the PVB already I mainly want to get the wiring and the valves out of the ground because of the animals around here. Not to mention that side of the lawn floods all the time, which makes the boxes move constantly.

I would love to use what I have because I really don't want to shell out more money for the system. But the "rodents" pretty much destroyed the wire right down to the solenoid. They are chewed bare, and 1 or 2 valves are malfunctioning anyway due to a recent lightning storm surge.



Pretty much figured I should ditch the old ones and get newer ones that fit the need.
