All tanks come standard with:

•      An ultra strong PVC riser which has a wheel load of 1.1 tonne which is fastened with stainless steel tamper resistant bolts. These risers come complete with an attractive green anti slip lid which blend in with your landscaping and lays flush with the ground level making it virtually unnoticeable.
•      Onga Dominator stainless steel submersible pump which is a completely silent pump for a complete home pressure system.
•      Onga WaterSwitch is a automatic rainwater controller which switches between mains supply and your rain water tank on demand and includes a dual check valve backflow prevention device. 
•      The LED display clearly shows which source is being used and in the case of a power interruption automatically switches to mains supply. Tank water is given priority for everyday applications such as your washing machine, toilets and garden taps.
•      Maintenance free self cleaning stainless steel flow through filter.
