Aquavalve by Autopot

The AQUAvalve is a simple and effective watering device. It is supplied with all AutoPot tray systems. Once connected to the water supply the AQUAvalve will control the flow of the water to the plants by simple gravity pressure from a tank or reservoir. No pumps or electricity or timers required. The AQUAvalve will open and allow water to fill the tray to the preset level of 20mm.
