Sure. Inline valves can go above ground. They'll still work the same way. The box underground is just to make it look better. Although, animals may start chewing at your control wires.



They make antisiphon valves too, meant for above ground installation. They have to be 6"-12" though above the highest sprinkler to operate correctly though.



If you use inline valves (above or below ground ) you still need a PVB or backflow preventer.

And I don't buy 42" as an avgerage freeze level in england

Put em above ground, do what ever you want with them

At least shut the system down and drian them/ blow them out during the winter season

Only reason I worry about the animals chewing on the wires is because they have here many times.

-A rabbit chewed threw an extension cord for Chistmas.

-Mole chewed on control valve wire the other day. Luckily it was just the outer jacket.

-My cat chewed on my speaker wire for the stereo system.

-Squirrel chewed fountain cord.

Luckily no animal was hurt in any of the processes.



I would definatly try to get the animals/nest out of the box. Seal the holes with that "Great Stuff" foam, and put a repellent or something in. They'll start messing things up in there, and chewing threw the poly pipe (if you have that)



Edit: I forgot your putting the valves above ground
