Frequently Asked Questions
What type of WC installation is this cistern designed for?
This cistern is designed for back-to-wall floor-standing WCs installed within furniture units, low pre-wall constructions, or drywall installations where a standard-height cistern won’t fit. The 355mm height and 132mm depth make it specifically suited to these applications.

The cistern is factory set to 5.8/3 litres. A reduction cup is included to reduce this to 4.0/2.6 litres for more water-efficient installations. The nominal flush rating is 6/3 litres.
Can this cistern be used with rainwater or greywater?
Yes — this cistern is compatible with filtered used water (rainwater/greywater) systems, making it suitable for eco-conscious installations.
