All My Valves are Buried - Why? How to Fix?

New property in Seattle. Have beautiful landscaping and irrigation but am trying to troubleshoot some of the system and every time I go to do something in the half dozen or so beautifully placed irrigation boxes, everything is buried in dirt. Have an emergency "guy" who said it's because it frost proofs the valves in this marginal area (had 1/2 inch of snow last year).

So what's the purpose of burying the valves and what's the most efficient way of exposing them so I can work on them? Should I rebury them later?

While we're at it, any hints on how I can figure out where the blow-out and main valve is? This house was built in 1928, obviously modernized, but things are never what they seem.

The presence of "frost" and that of "snow" or two different things.

Look near the source of your water service (water meter) or well for a back flow preventer valve and the sprinkler shutoff valve.

Even with "frost" or slight freezing, you shouldn't have to bury the cans. Not knowing what type you have, some models have provisions for stacking to bring the tops closer to grade level. You may be able to buy different size riser rings to keep it flush, yet not have to bury it. If you have the feeling they might freeze, you could always stuff insulation in the boxes. I think there was a very lazy installer on the job the day yours was installed.
