    Is it bad to control 2 valves on one zone? Or should it always be 1 for 1?

    THanks,

    I mean what are you running off the zone?

    do you mainfold?
    I have never heard about 2 valves on 1 zone.....but im not gods gift to irrigation..guys like wet boots/purp haze/dirty water are pretty good on this stuff..

    let me know how it goes buddy

    Most controllers can manage it, with the provision that you are not powering a master valve or pump relay. What's the reason for running two valves at one time?

    I'm going to say he needs to match output GPM better. I'd say something like running drip concurrent with a rotor zone.

    Like Boots said - you can run two zones on a controller station.
    Some instances might be:
    Two small zones seperated by larger zones. ie. small turf panels that are not large enough for rotors. Wire them together to utilize system flow capacity.

    Two small areas seperated across a large expanse of paving or concrete. Rather than running an additional long length of pipe through a sleeve (if there is a sleeve available) wire two smaller valves together and utilize system flow capability.

    You can water two drip zones that are widely seperated can be wired together to get the most out of the system.

    On a large system 4" ML or larger with a small water window, you can run multiple zones simultaneously. On a 6" looped ML with a 4" meter we ran two controllers at a time, two valves per station (70-75 GPM/valve) in order to get them done within the water window we had during restriction periods. We actually had 5 controllers and 150 2" valves. Had the ability to water the area once every 5 days and no daytime watering.(Austin, TX. water restrictions). Did some creative scheduling and divided the property into 4 water day sections. Worked fine.

    So, yes if you need it, you can run multiple zones on the same station.

    Yes you can, like the guys said above.
    Rotar has learned quickly, tell me Rotar, what does "do you manifold" mean?
