I just dug up a bunch of clay soil/rock to get to all of the sprinkler
value piping underneath the anti siphon values and it took way too
long and tiring. Any recommendations on what type of soil I should
replace it with so that I can easily dig up the same area for any
future repairs?
Use course sand or small pea gravel, and you can suck it out later with a
shop-vac.
Don't replace the soil. Put in valve boxes so you can take off the lid
and access the valves
right away.. Put 2-3" of pea gravel in the bottom of the hole first.
