Anyone familiar with Weathermatic valves?
I had an 11-zone system installed in Oct of '03 and have had continuous issues with the Weathermatic valves. I've had no less than 20 solenoids replaced on the valves, all at the irrigation company's expense. At the end of last season, I forced them to replace every valve in the system with new ones. They only replaced the solenoids and agreed to extend my warranty on the system itself. Here it is in July and they are starting to fail again. I'm quite tired of coming home to find another Error on the controller (the controller is a Hunter Pro-C).
The owner of the irrigation company is baffled by my problems and did tell me that there we some issues with Weathermatic valves, but I have been unable to locate anything documented. Does anyone know of any design issues with them?
