Installation & Maintenance Advice
Isolate both hot and cold water supplies before attempting installation. Unscrew the shower hose from the diverter outlet to access the housing. Carefully extract the old diverter nipple, cup washer, and O-ring. Clean any limescale or debris from the internal brass chamber before seating the new cup washer, lubricating the replacement O-ring with WRAS-approved silicone grease, and threading the A963170AA nipple firmly into place.
