Rain Aid® by Apex Valves

The Rain Aid is a supplemental valve that allows you to integrate your normal water supply as a backup to your rain harvesting system. The Rain Aid opens, allowing water from a normal water source to fill and maintain the tank water level when it drops below a pre-set limit. This supplements your rain harvesting and does not at all impede normal rain collection.

  • Backup water supply control valve for rainwater collection.
  • The RainAid® ("RA20") valve is designed to be connected to the main water supply on a rainwater retention tank.
  • It provides a backup supply of water in the event of demand exceeding the on-hand supply of rainwater, whilst ensuring maximum rainwater storage at the next rainfall.
