It was only zone 1 that i replaced. I have two wires on that solenoid, one going to the bundle with the common wire and the other going to the zone 1 sprinkler. Now on the bundle i have 5 wires attached, three for each solenoid and 2 white common wires. the other common is for the zones in the back.The solenoids you replaced, were zones 1 and 4 apart of this replacement?
You wired to wires incorrectly.. Most likely wired in series. Pull the 2 wires that connect the valves to each other and wire it into the main common bundle
I forgot to say that I installed a new controller box on the wall and thats when I noticed the problem, i then took that box off and put the old box back on and it still did the same thing.just to make sure, re-do the splices in the valve box- all of them. If that didn't fix it
Use a multimeter and test for voltage at the controller while you have either zone on. touch the common and that particular zone .. You are looking to see if the controller is sending power to multiple zones
Are zones 1 and 4 in the same valve box or is one in front and one in back. One quick check you can do is dissconnect one of the two stations at the clock. If both still come on the wires are cross-connecting in the valve box and as mitchgo says redoing the connections should fix the problem.
