One zone continues does NOT have a valve

System has 9 zones with Rainbird ESP modular controller. Only two zones have remote valves. One of the other zones is seeping at each head. Any suggestions on what might cause this? So far I have reset the controller and replaced the first head in the zone. Then I ran the zone manually, shut it down, and ran the next in order. When the second ran, the first continued to run also. (Yes, I, too, wish they had installed a valve for each zone when they built the system.)

How many wires are connected to the controller output terminals? You may have zone control valves you don't know the location of.

Valve

Did the first zone shut off with the timer? Or did you have to turn on your main shut off valve?

One zone continues does NOT have a valve - wiring

Thank you, Wet Boots. This is an indoor controller. There is one wire to each zone, and two wires to COM. There are no wires to MV or YT. Also, the rain sensor was not connected so there are no wires there. The only other wires are the 120V connector and the battery back up. I am very sure there are only two remote valves and each only controls one zone. I say that because when I manually turn on the valve only the heads in one zone come on. Also, the wiring in the valve box is only for one zone.
Thank you, also, irrigirl. When I ran the zone after swapping the #1 head, I turned the zone off manually with the controller and then turned the next zone on. Both ran. The only way I have been able to stop the seeping (each head in the zone seeps) is by shutting off the electricity at the pump. This is not on city water but has its own submerged pump in the lake we live on.

Valve

It is more than likely your valve. I am not too familiar with remote valves, but does this valve have a diaphragm?
If you look at your wires connected to your timer/circuit board, are there are 9 (1-9) connected?
Also, did you turn off the zone by turning the timer to off? And then it was still leaking at the heads?

Also, I am confused by your title...
"Does not have a valve" ? Your sprinklers should be attached to a valve...

Remote Valve location

The system was installed several years ago and we only know of two remote valves. Each controls one separate zone. I do not know of any way that the other zones can operate without some mechanical apparatus that regulates the water flow to the differing zones. (I do not know of anything that fulfills this purpose other than a remote valve.) Today I have been digging around each of the heads in the problem zone. My thinking is to determine how each head branches from the secondary water line. Then I will try to determine where the main water line intersects this secondary line. I am assuming that if there is a valve it will be attached to this secondary line somewhere near its intersection with the main. Am I on the right track? Does anyone know of any other way for the flow to be regulated without a mechanical apparatus that is electronically activated by the controller? Is there a better (read easier) way to determine the water pathway and/or the location of this activator?

I would be taking photographs of the controller wiring and uploading them. We still have no explanation of the confusing words "one zone does not have a valve" - Let some photos do the talking.

As for locating missing valves and wiring, one can use a locator to track the wiring.

I would like to know the answer to Wet Boots' question...
How many wires are connected to the controller output terminals? You may have zone control valves you don't know the location of.

You said there is a wire to each zone terminal... Are there only two or are there more. We need to know please
