Installation & Measurement Advice
Check Thread Size Before Ordering: This valve features a standard UK 1/2" BSP thread (measures approximately 20.5mm to 20.9mm outside diameter across the threads). It will not fit European 3/8" BSP connections (approx. 16.6mm OD) commonly found on imported concealed cisterns. Ensure your cistern has a side-entry aperture and verify internal tank width to allow free movement of the float arm.
