Installation Guide
- Attach valve to tank inlet using BSP threaded connection.
- Apply PTFE tape or approved sealant to the inlet thread for a watertight seal.
- Screw valve into female thread by hand until firm, then tighten using a spanner or pipe wrench on the hex body.
- Fit lever arm and float – thread the lever through the copper float and secure with cotter pin.
- Pressurise and test the system for correct operation and shut-off.
- Fine-tune float position for optimal water level control.
