Dual Flush Water Saving
The dual flush system provides two flush options for maximum water efficiency:
-
Full Flush: For solid waste – typically 6 litres per flush
-
Half Flush: For liquid waste – typically 3–4 litres per flush
Compared to older single-flush cisterns (9–13 litres), this dual flush system can reduce water consumption by up to 60%, saving money on water bills and helping the environment.
Front & Top Access
This cistern offers both front and top access for servicing and maintenance:
-
Front Access: Service through the push button opening — ideal where top access is restricted by shelving, cabinets, or low ceilings
-
Top Access: Full access from above for major servicing or component replacement
WRAS Approval
The flushing valve and all water fittings are WRAS (Water Regulations Advisory Scheme) approved, confirming they meet UK water supply regulations. Essential for professional installations and building regulations compliance.
