Question
I bought a new house with existing sprinkler systemThere are seven stations; stations 1, 2, 6 all run the same heads,  and the water pressure is too low. For the first month,  zones ran independently. All those zones are on the right side of the house. I located the valve box but don't know what I'm doing. Zone one is front of house,  two is side,  six is supposed to be back right. They just all turn on for each station. Thanks for the help.

Answer
Hi Stefan,

Make sure the zones wires are not jumped, it should be one wire from the controller to one valve at the valve box. Lets say if port 1  has a red wire, the zone 1 at the valve box should have the same red wire connected to the solenoid and the common wire, white.

Probably in somewhere the same wire is connected to zones 1,2,6.

Hope this helps,
Guillermo.
