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 continental concealed frames. Fit through the side hole of the cistern with the rubber washer inside the tank and secure firmly with the external backnut. Do not overtighten against ceramic walls.
