control valve Irritrol 2400/2600
I have a zone that once opened, wont shut off. Replaced the solonoid, but still runs. Wont stop unti I turn off main water supply. Should I replace the diaphram, or the entire valve?
Diaphragm
Hi William, it's most likely the diaphragm. Easy job on that valve. Look for debris inside the valve as well.
Good luck!
If I can't fix it, it's broken!
I too would conclude the diaphram. go for it.
