Hydraulic system repair

Gents,
Ran into an hydraulic system today, guessing that's what it's called.

Little 1/4" dia. lines running from controller to valves, which are buried who know's where.

Problem is that one zone runs all the time. System works fairly well due to good water pressure, but obviously one zone is way overwatered.

needs replacing with new controller & valves.

Any advice on finding valves? replacing all these items? Any other "gotchas" to expect?

Thanks

That works really well as Jim told me that. However if that doesn't work for you do you just find the first head that comes on after you turn the water on and then fish tape your way back will eventually find a valve. I have done plenty of hydraulic conversions in my lifetime!

Found em and converted.

There was a slight depression in the ground not far from where the control tubes came out, and the lady of the house kinda remembered something being there.
A little digging and bingo, had a wood box, now very rotted, over them.

You're right to a certain degree jay, that is if the valve isn't in the middle of the zone. If the valve's centered on a tee they're still a tough find. If the system is large enough and has head to head and is centered on or near the mainline you can measure the distances between heads and swing an arc which should intersect the mainline. That intersection of the main and the arc should be the best place to search. I've done it on a few sports fields in order to create hard points of interest or draw parameters.
