Thanks for responding.
This zone and control valve are in the front yard and valve is in its own box. It was working just fine about a week ago and the only thing that I have done to the system was some repairs to the zones in the back yard. I had to replace two solenoids on zones in the back yard (control valves are in the back yard as well) and fix a cracked pipe (also in the back yard).
just wanted to mention the above in case it could have impacted anything. I will look to take the c
ontrol valve and see if the
seat washer has broken off.
