Water draining out of bottom head of zone

A customer has 10 sprays on a zone. The bottom head always seaps after it is turned off. I have already checked the valve and it is ok. I believe it is due to the size of the zone and the volume of water still in the line

This is prob low head drainage. Use heads with check valves. How much is the elevation drop from the highest to lowest head.

Are you sure the valve is not seeping? Listen to it. Look at the water meter with everything turned off and see if the wheel is ssslowly turning.

I can't a find a valve on the whole property. I did shut the meter off and the water drained out of the line within 15 min with the head off. Could I put SAMs on the lower heads or would I be better off putting heads with ck valves in them

SAM = seal a matic = check valve

If it stopped when you turned off the meter and it's going on 24x7 when the meter is on, you have a weeping diaphragm. Find the valve and rebuild it, a SAM will just move the problem to the next lowest head.

You may have misunderstood me, when I said turn everything off I meant to leave the meter on but nothing else on meaning different stations or if the system is on the same meter with the house make sure nothing in the house is running.

Also, what everyone else said applies.

Now which valve did you check and why would the head stop leaking after the water was shut off.

Depending on the elevation drop, I've had to replace heads all the way up the grade.

Yo dad, you still got it. Just use checks in all your heads.
