RainAid

Note: This product can only be used in QLD

The RainAid valve automatically switches water supply from rainwater to mains water in the event of rainwater demand exceeding rain supply.

• Simple to install. No Electricity required.
• Standard's approved for mains water connection.
• Rainwater fills tank at the next rainfall.

 

 

The RainAid valve is designed to be connected to the mains water supply on a rainwater collection tank. It will provide a backup supply of water in the event of demand exceeding rain supply.

Operating Principle
Under normal conditions, rainwater will fill the tank. If the water level drop below a predetermined level, The RainAid valve will maintain the water level at this point using the mains supply. The minimum water level is easily set at any height during installation by adjusting the cord length.
Note: it is important to keep a head of water to the pump at all times. There is a 100mm differential between the open and closed positions of the RainAid valve. The rainwater tank is used to supply water to non potable outlets such as toilets, laundry and garden.

First Flush Water Diverters

Fitting an appropriately sized First Flush Water Diverter is critical to achieve good quality water. Water Diverters improve water quality, reduce tank maintenance and protect pumps by preventing the first flush of water, which may contain contaminants from the roof, from entering the tank.

When it rains, water slowly builds up in the roof guttering system before it exits through the downpipe. The first flush of water from the roof can contain amounts of bacteria from decomposed insects, skinks, bird and animal droppings and concentrated tannic acid. It may also contain sediments, water borne heavy metals and chemical residues, all of which are undesirable elements to have in a water storage system.

Fitting an appropriate sized water diverter is critical to achieve good quality water.

Instead of flowing to the water tank, these pollutants are diverted with the initial flow of water into the chamber of the water diverter. The water diverters from Rain Harvesting utilise a dependable ball and seat system - a simple automatic system that does not rely on mechanical parts or manual intervention.

As the water level rises in the diverter chamber the ball floats, and once the chamber if full, the ball rests on a seat inside the diverter chamber preventing any further water entering the diverter. The subsequent flow of water is then automatically directed along the pipe system to the tank.

For a water diverter to work effectively, the contaminated water in the chamber must be sealed off. This prevents the water passing to the storage tank and ensure the water does not "syphon" off the contaminated water in the chamber. The simplest and surest way to do this is with a floating ball and seat.

A slow release valve ensures the chamber empties itself after rain and resets automatically. The diverted water need not be wasted water because the drain pipe from the diverter chamber can be fitted to a standard drip irrigation system.
