3. Setup and Installation
This basket valve is designed for standard sinks. Before installation, verify your sink's specifications:
- Sink Hole Diameter: 85 mm

Installation Steps:
- Ensure all components listed in Section 2 are present and undamaged.
- Place the gasket securely between the sink's drain opening and the top flange of the valve base. This creates a watertight seal.
- Insert the valve base into the sink opening from above.
- From underneath the sink, attach and tighten the mounting screw to secure the valve base. Ensure it is snug but do not overtighten, as this can damage the components or sink.
- Insert the stainless steel strainer basket into the valve top.
After installation, run water into the sink and check for any leaks around the valve connection.
4. Operating Instructions
The Cornat Recycled Basket Valve provides a simple mechanism for controlling water drainage and preventing debris from entering your plumbing system.
Controlling Water Flow:
- To Close the Drain (retain water): Press the stainless steel strainer basket down firmly into the valve opening. This will seal the drain, allowing water to accumulate in the sink.
- To Open the Drain (allow water to flow): Pull the strainer basket upwards. This will unseal the drain, allowing water to pass through.

The strainer basket effectively catches food particles and other debris, preventing them from entering and potentially clogging your drain pipes.
5. Maintenance
Regular maintenance ensures the efficient operation and extends the lifespan of your Cornat Recycled Basket Valve.
Cleaning the Strainer Basket:
- Periodically remove the strainer basket from the valve by pulling it upwards.
- Discard any accumulated food particles or debris.
- Rinse the strainer basket thoroughly under running water. A small brush can be used to remove stubborn residue.
- Reinsert the clean strainer basket into the valve top.
General Care:
- Wipe the visible stainless steel and recycled plastic components with a soft cloth and mild, non-abrasive cleaning solution as needed.
- Avoid using harsh chemicals, abrasive cleaners, or scouring pads, as these can damage the finish and material.
