Question
where can I buy Hardie valve diaphragm in the Sacramento area.
one of the cycles does not close, I think I need to replace the valve diaphragm or the solenoids I am not sure which. Can you help?

Answer
Hey Wendy, I'm not real familiar with Ca. vendors, but I know of a company called "Ewing Irrigation" that has stores all over the southwest U.S. including Ca. I would think they have one in or close to Sacramento. It could be either the diaphram or the solenoid, but it would be beneficial to replaced both at the same time. Good luck and have a great day.
