Sometimes natures reserve doesn’t quite have enough to meet our every day rainwater requirements. On those occasions the Hansen Slo-Flo Rain Relief Valve provides what’s needed. If the tanks rain water level drops below minimum, the Hansen Slo-Flo Valve opens to supplement the tanks water from an alternative source such as the mains water supply. However it will only increase the water level by either 50 or 100mm in case it rains the next day.

  • Prevents dry tank syndrome
  • Supplement your rain water tank from an alternative water supply, once level reaches pre-set level
  • Dual level weighted float determines the tanks fill depth of either 50mm or 100mm
