- Turn off the main water supply.
- Using an adjustable spanner, remove the tap cover, placing a cloth between tap and tool to prevent scratching.
- Use an open-ended spanner to unscrew the gland nut, and expose and remove the old washer.
- Use a re-seating tool to shave the tap seat back to a flat, shiny surface.
- Replace the O-ring on the spindle and apply grease.
- Flush away filing debris and insert spindle with the new tap washer.
- Reassemble the tap (taking care not to over-tighten the gland nut) and turn main water supply back on.
We always recommend you buy replacement tapware or fixtures from a recognised plumbing supplier, as their items will always be covered by warranty should any fault occur – unlike when you buy from a regular hardware store or chain.
