Fitting Instructions for Bidbury & Co Traditional 3.5″ or 1.5″ Victorian Wastes and Waste Disposal Adapters

When installing a waste into a ceramic sink, traditional rubber seals are not recommended, as they do not provide a reliable watertight seal due to the uneven nature of ceramic surfaces. Instead, we recommend using a high-quality silicone sealant for the best results.

1 Prepare the Sink and Waste

• Ensure the sink waste hole is clean and dry.
• Remove any debris or dust that may prevent proper adhesion.

2 Apply Silicone Sealant (Top Side)

• Apply a small, even bead of high-quality silicone sealant around the underside of the waste flange.
• Insert the waste into the sink hole, pressing down firmly to ensure an even seal without any silicone squeezing out.

3 Seal the Underside

• On the underside of the sink, apply a generous amount of silicone around the waste fitting.
• This compensates for the rough, unglazed surface and ensures a watertight seal.

4 Secure the Waste

• Fit the centre nut and tighten it carefully, ensuring even pressure without over-tightening.
• Remove any excess silicone with a damp cloth before it cures.

5 Allow to Cure

• Leave the silicone to cure fully as per the manufacturer’s instructions before running water.

6 Test for Leaks

• Once cured, run water through the sink and check for any signs of leaks.
• If necessary, reapply silicone in any areas where water may be escaping.

Note: Avoid using the sink for several hours after installation to allow the silicone to fully set.

By following these steps, you ensure a secure, watertight fit while maintaining the clean aesthetic and functionality of your Bidbury & Co waste.
