Setup & Installation
Follow these steps for a secure and leak-free installation. It is recommended to use plumber's putty or silicone sealant for optimal sealing, in addition to the provided gaskets.
- Prepare the Sink: Ensure the sink hole is clean and free of debris.
- Disassemble the Drain: Separate the top stopper assembly from the main drain body and remove the locknut and gaskets from the bottom.
- Apply Sealant (Optional but Recommended): Apply a thin bead of plumber's putty or silicone sealant around the underside of the drain flange that will sit on the sink surface.
- Insert Drain Body: From the top of the sink, insert the main drain body (with the top gasket and flange) into the sink hole. Ensure the overflow holes on the drain body align with the sink's overflow opening.
- Secure from Below: From underneath the sink, slide the rubber washer, then the plastic washer, and finally the locknut onto the threaded portion of the drain body.
- Tighten the Locknut: Hand-tighten the locknut initially, then use a wrench to gently tighten it further. Do not overtighten, as this can damage the sink or drain.
- Install Stopper: Insert the pop-up stopper into the drain body.
- Connect P-Trap: Connect your P-trap assembly to the bottom of the drain body, ensuring all connections are tight and sealed.
- Test for Leaks: Run water into the sink and check underneath for any leaks. Fill the sink and then release the stopper to ensure proper drainage and no leaks.

Operation
