SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

I have over 12 HARDIE sprinkler valves throughout my yard and most of them work fine, I currently have 2 valves that are not letting enough water pressure out of the valve, my question is where can I purchase the Solenoids for the HARDIE sprinkler valves, I know the systems are very old but they are heavy duty valves and I prefer them over the newer plastic valves. Let me know where to find the Solenoids for the valves.
