The same AQUAvalve that is supplied with every AutoPot System. Once connected to the water supply, the AQUAvalve will control the flow of water to the plants by simple gravity pressure from a reservoir or tank of any size. No pumps, mains water pressure, electricity or timers are required.
Once connected to a reservoir the AQUAvalve will open and allow water to fill the tray to a pre-set level of 20mm. The AQUAvalve will not refill the tray until all the water has been used. This ensures that the plants are not constantly sitting in water. Once all the water has been used by the plants the AQUAvalve will re-open and refill the tray.
The AQUAvalve is a simple and very effective watering device that requires only simple maintenance. Just keep the AQUAvalve and the tray it sits in clean free of obstructions such as soil particles and it will feed and water your plants for many years.
How does the AQUAvalve work?
1. Once the reservoir is filled with water and liquid feed, it will begin to travel through the pipe from the reservoir. It will pass through the AQUAvalve nozzle (1) and into the tray. As the tray fills (2) with water air is trapped inside the main body and around the ‘inner float’ causing it to try and rise (3).
2. As the water level increases in the tray, the ‘top float’ will rise (1). Releasing the trapped air inside the main body (2). This will, in turn, allow the ‘inner float’ to rise and shut off the supply (3). The water level is now 0.7″.
3. Potted plants in the tray will start to reduce the water level (1). As the water level reduces the ‘top float’ will close creating a vacuum inside the ‘main body’ of the AQUAvalve (2). This vacuum traps water inside the ‘main body’ and in turn keeps the ‘inner float’ up and the incoming water shut off (3).
4. When the water level in the tray has run out completely (1) the surface tension around the main body of the AQUAvalve will break, this can take up to 30 minutes. As this happens all the water that is trapped inside the ‘main body’, keeping the ‘inner float’ up and the water supply shut off is released, allowing the ‘inner float’ (2) to drop and open the water supply (3).
