    RainAid Tank Top Up Valve 

    Under normal conditions, rain water will fill the tank. If the rainwater level drops below a pre-set level, the RainAid® valve will open to maintain the water level using an alternative source. Connects via 3/4" male pipe thread.

    An amazingly effective device for maintaining sufficient supply in the event demand exceeds rainwater supply. Does not require electricity or any complex float switch devices. High flow rate enables rapid refilling of rainwater storage tanks.

    MUST BE INSTALLED BY A LICENSED PLUMBER OR PRIVATE WATER SYSTEMS CONTRACTOR WITH PERMITTING FROM CITY/TOWNSHIP OF RESIDENCE (INCLUDING PUBLIC WATER DEPARTMENT IF APPLICABLE)

     

    Application:

    • Backup water supply control valve
    • The RainAid® valve is designed to be connected to a municipal or well water supply on a rainwater storage tank. It will provide a backup supply of water in the event of demand exceeding rain supply, while insuring maximum rainwater storage at the next rainfall.
    • Assists in keping a minimum water level in tanks which must be kept filled to a certain water level
    • Helps keep tank filled for fire fighting purposes

    Operating Principle:

    Under normal conditions, rain water will fill the tank. If the rainwater level drops below a pre-set level, the RainAid® valve will open to maintain the water level using municipal or well water.

    Installation Instructions:

    IMPORTANT

     

    • Tank overflow should be visible (to detect malfunctioning valve)
    • Pump must have 'dry-run' protection
    • Failure to affix label, supplied with valve, near the overflow discharge will void warranty
    • Water loss is not covered by the manufacturers warranty
    • Cord must hang freely
    1. Install valve horizontally. Do not install on an angle.
    2. DO NOT restrict flow
    3. Inlet pipe must be clean
    4. Ensure the washer is fitted on the inside of the tank.
    5. Use thread tape and do not over-tighten
    6. Measure the required cord length 'L' as shown on the illustration.
    7. Trim the cord length.
    8. Thread the cord through the hole at the end of the lever. Tie a knot in the end of the cord to secure it.
    9. Ensure the weight is secure at the other end of the cord.
    10. Place the weight in the tank. (It will sink if the tank is full of water)

     

    • The RainAid® valve MUST NOT be fitted to tanks used partially or entirely for storm water detention. (Detention is the slow release of water run-off to the storm water drain during and after rainfall events).
    • Do not restrict inlet water flow.
    • Not to be modified.
    • Valve must be installed horizontally.
    • Overflow discharge must be visible.
    • Overflow and air gap to comply with local standards (air gap of 3 x municipal water inlet pipe diameter - 55mm - complies with AS/NZS 3500.1)
    • The minimum water level (L) is easily set at any height during installation by adjusting the cord length.
    • Cord must hang freely.
    • Failure to affix label, supplied with the valve, near the visible overflow discharge will void Warranty.
    • Some Australian states stipulate a minimum water level that must be maintained for fire fighting purposes.
    • Best practices stipulate a visible air gap.

    Important Legal Notice:

    Overflow discharge must be visible. If overflow is discharging when there is no rainfall, isolate water supply and call a plumber immediately. This discharge comes from your metered water supply. Water loss is NOT covered by the manufacturers warranty.

    The RainAid valve is a mechanical water shut-off device which requires periodic maintenance.

    Every 6 months, check that the valve functions correctly. Gently push the lever down. When the valve opens, release the lever. When the weight is submerged, the valve should close. If the valve fails to shut off completely, it may be necessary to clean, service or replace it.

    Warranty is limited to any fault found in a valve due to poor workmanship or materials that is returned to Apex Valves Ltd within 1 year from the date of manufacture.

    Servicing:

    1. Servicing is not likely to be required if the valve is fitted to a municipal water supply.
    2. Spanner is necessary for disassembling the valve for servicing if this is required.
    3. Servicing details are provided on the packaging.

    How to back-up your rain tank with city water: RainAid valve

    We at Rain Brothers, LLC restored this old brick cistern to be used for irrigation. For a back-up water supply, we installed a RainAid water supplement valve to introduce well water into the tank once the cistern water level gets below a pre-set point.
