Valve depth

I'm going to replace all 7 valves and I noticed that the valves are at a depth of about 2 feet. Can I just add some elbows and raise them to a reasonable depth?

If you install quality valves, you won't have to service them for years. For deep-set valves, avoid jar-tops, and stick with conventional designs.

I replaced the one Toro 250 that would not stop leaking with a Hunter PGV with flow control. I'm also going to replace the other 6 since 2 others are acting up too.

If all the valves are in one location, you could construct new valve manifolds at a shallower depth. Assuming these are near to the house and the water supply, you would also replace the old underground upstream pipe with shallower plumbing, with the idea of not having low points where water could freeze and cause damage

The valve I just replaced was by itself. The rest are in pairs. I guess in a way it's a good thing that they're deep because they will not freeze.
