The RainAid valve is the ideal way of controlling the backup water source (mains or other) on a rainwater collection tank. It will ensure your rainwater tank never runs completely dry in the event of demand exceeding rainfall (supply).You can easily set the valve so that it maintains a set (minimum/maximum) level of water in a tank.
That level can be as low or as high in the tank as you need...letting you determine how much storage you want in reserve to catch the next inflow of rain.
Designed to control the level of water in a Rainwater tank via a backup supply source.
Adjustable water level.
Allows maximum storage of rainwater.
Watermark approved (License no 20368 to AS1910. SAI Global) for mains water connection.
