I've had several of those auto watering systems and the fancy programmable ones die fairly often. Especially when the batteries get discharged. Hence someone should have a broken one somewhere if you can source it. Sounds easy enough to hack the wiring to get at the motor lines. So if you want cheap. . . ask around.

In a classic example of how discussion forums like this get you to reconsider concepts that may have been discarded for inadequate reasons the penny finally dropped.

If one piano wire inner flexi cable isn't quite strong enough to reliably push the tap fully off use two. Needs a double sided pivot connector on the tap and acutating levers with double cable mount fulcrums but thats relatively easy. Bit of overtravel on the drive side will bend the wires producing a keep it shut spring. Two flexi cables will threadal though almost as easy as one to where there is plently of room for a powered operator. Undecided whether to get an RC servo and drive or just use one of the door lock motors I have in stock. no going to get done immediately as other things have priority but at least I have a method.

Thanks

Clive.

If you speak to a heating/ ventilation contractor or dealer just ask them for a DC zone valve actuator for hydronic zone heating. There are many varieties of AC and DC actuators for these products. A useful property of them is slow operation and high flow when open. Many have spring return feature when power is off. Most have excellent long term reliability.

Honeywell and MUT are two good brands. JD
