Hello,

My irrigation system has five zones: 2 control the drip system and 3 control the sprinklers on the lawn. I recently had the valve replaced that controls the drip system. When the water was turned back on after the valve replacement, all 3 lawn sprinkler valves broke.

Two of the three zones are randomly coming on for a few seconds at a time every 15 minutes or so. The other zone was 'turned off' but is leaking continually all over the lawn.

Is it possible that the replacement of one valve put more water pressure on the other valves and blew them all? I'm having trouble believing this. Any thoughts?

Thanks,
Kelly
