Zone Stays on All the Time
OK, I have read many topics similar, but still don't know how to resolve. It started with a leaking zone, which I suspect I have fixed by disassembling the suspect valve for this zone, in which I found debris on the diaphram seat. But, after reassembling the valve and turning back on the water (with the controller still off) the zone came on. I thought perhaps I did not reassemble the valve correctly, so I disassembled the next zone in the valve box to study again how the valve should be assembled.....then reassembled both zones and now both zones are always on, even with the controller off. This is a Toro system, probably 10 years old. The solenoid is contained in a plastic housing which screws into the lid of the valve. The lid of the valve screws into the body of the valve. Both are integral threads in the plastic housing (not 4 screws, etc. as I have read within this forum). In both instances, I unscrewed the valve first, the lid second, removed the diaphram, spring, etc. and cleaned. Then I replaced the diaphram, set the spring and pintle into the lid, then replaced the lid. And finally, replaced the solenoid to the lid. There is an indication on the solenoid that you can manually turn the valve on at the valve. Have I done something to activate this feature which makes these valves always on?? How do I undo whatever I have done and get these zones to work on the controller again???
