Cistermiser - Standard Pressure Valve

One of the original flush controllers from 25 years ago, this Cistermiser works by sensing the drop in water pressure caused by hand washing.
No electronics, no sensors. They are still chosen by some, nevertheless.

This model is for use with:
- Mains water or tank-fed systems above 5 metres head
- Operating sensitivity is 10% of supply pressure

Includes:
- Flush controller unit for compression fit to cistern water feed.

Features:
- Up to 80% savings on water costs
- Reliable and low maintenance
- Water pressure sensor for detecting bathroom occupancy
- Adjustable fill time
- Adjustable operating sensitivity
- WRAS approved product

How it works
The Cistermiser hydraulic valve is installed on the supply pipe to the urinal cistern.
The valve is activated by short-term pressure drops created by use of taps or WCs on the same supply.
The valve is normally closed; when it is activated it opens and water passes to the urinal cistern until the pressures on both sides of the valve are equalised.
When the cistern is full the auto-siphon will flush.
