Product Overview
The Franke 900W Sink Strainer is designed to prevent food particles and debris from entering your plumbing system, ensuring a clear drain. It features a durable construction and a convenient lever for easy operation.
Key Features:
- Stainless steel construction with a white coating for durability and aesthetics.
- Designed to fit standard 3.5-inch sink drain holes.
- Equipped with a replaceable sealing gasket for a tight, leak-resistant seal and extended lifespan.
- Adjustable, center post design with a removable basket.
Setup and Installation
Before beginning installation, ensure you have the necessary tools: plumber's putty or silicone sealant, a wrench, and a screwdriver. Always turn off the water supply to the sink before starting.
- Preparation: If replacing an existing strainer, remove the old unit and thoroughly clean the sink drain opening.
- Apply Sealant: Apply a thin bead of plumber's putty or silicone sealant around the underside rim of the strainer body that will sit in the sink opening.
- Position Strainer: Insert the strainer body into the sink drain opening from the top. Ensure it is centered and seated properly.
- Secure from Below: From underneath the sink, place the rubber gasket, then the friction washer, and finally the locknut onto the threaded portion of the strainer body.
- Tighten: Hand-tighten the locknut, then use a wrench to tighten it further. Do not overtighten, as this can damage the sink or strainer. Wipe away any excess plumber's putty or sealant.
- Connect Plumbing: Attach the drain pipe to the threaded tailpiece of the strainer according to your plumbing setup. Ensure all connections are secure and watertight.
- Test for Leaks: Turn on the water supply and fill the sink. Check for any leaks around the strainer and plumbing connections.

Operating Instructions
The Franke 900W Sink Strainer is designed for simple operation to manage water flow and prevent debris from entering the drain.
- Straining Mode: To allow water to drain while catching food particles, ensure the basket is seated correctly in the strainer body. The perforations in the basket will filter debris.
- Sealing Mode: To fill the sink with water, push the lever down firmly. This will engage the stopper at the bottom of the basket, creating a seal to retain water.
- Draining Mode: To release the water, lift the lever upwards. This will disengage the stopper, allowing water to flow freely through the drain.
- Removing Basket: For cleaning or to access the drain, simply lift the basket out of the strainer body.
Maintenance
Regular cleaning and maintenance will ensure optimal performance and extend the life of your sink strainer.
- Daily Cleaning: Remove the strainer basket daily and empty any collected food debris into the trash. Rinse the basket under running water.
- Deep Cleaning: Periodically, clean the strainer basket and the inside of the strainer body with warm soapy water and a soft brush. For stubborn stains, a mild non-abrasive cleaner can be used.
- Gasket Inspection: Inspect the sealing gasket periodically for signs of wear or damage. If the gasket is cracked or no longer provides a tight seal, it should be replaced.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, or harsh chemical drain cleaners, as these can damage the finish and materials of the strainer.
