1. Introduction
Thank you for choosing the Waterstone 9850-SN Contemporary Pulldown Faucet. This manual provides essential information for the proper installation, operation, and maintenance of your new faucet. Please read these instructions thoroughly before beginning installation or use to ensure safe and efficient operation.
The Waterstone 9850-SN faucet features a thin, sleek body design for a clean and simplistic look. It includes a "Positive Lock Pulldown" design that securely holds the sprayer in place when not in use, preventing sagging. The spout offers an 8-5/8 inch reach and can swivel 360 degrees, complemented by an anti-rocking spout assembly for smooth, wobble-free movement. The lever handle spray head extends 18 inches from the spout, and a counterbalanced weight ensures smooth pull-out and prevents snap-back. The sprayer instantly diverts water from an aerated stream to a wide spray when the handle is held. An innovative wave spring handle tension system prevents sagging and requires no adjustment. The single handle can be mounted in front, right, or left positions, and when mounted on the side, it can adjust 22.5 degrees for backsplash clearance. This faucet is equipped with a new 25mm hot/cold ceramic disk valve cartridge, resistant to reverse osmosis water, and is made from eco-friendly solid brass or 316 stainless steel.
2. Safety Information
Please observe the following safety precautions during installation and use:
- Always turn off the main water supply before installing or servicing the faucet.
- Wear appropriate personal protective equipment, such as safety glasses and gloves, during installation.
- Ensure all connections are secure to prevent leaks.

- Keep children away from the installation area.
3. Setup & Installation
This section outlines the steps for installing your Waterstone 9850-SN Pulldown Faucet. The faucet is designed for single-hole deck mount installation.
3.1. Before You Begin
- Unpack all components and verify that all parts are present.
- Turn off the main water supply to the installation area.
- Clear the area under the sink for easy access.
3.2. Installation Steps
- Prepare the Mounting Hole: Ensure your sink or countertop has a single hole suitable for deck mounting. The faucet is designed for this configuration.
- Install the Faucet Body: Insert the faucet body into the mounting hole. From underneath the sink, secure the faucet using the provided mounting hardware (washer and mounting nut). Tighten firmly but do not overtighten.
- Connect Water Supply Lines: Connect the hot and cold water supply lines to the corresponding inlets on the faucet body. Use thread sealant tape on the threads and tighten connections securely.
- Install the Pulldown Sprayer: Feed the sprayer hose through the faucet spout. The lever handle spray head pulls out 18 inches from the spout.
- Attach Counterbalanced Weight: Attach the counterbalanced weight to the sprayer hose underneath the sink. This weight ensures smooth pull-out and prevents snap-back of the sprayer.
- Connect Sprayer Hose to Supply: Connect the sprayer hose to the dedicated outlet on the faucet body. Ensure a watertight seal.
- Position the Handle: The single handle can be mounted in front, right, or left hand positions. When mounted on the side, the handle can adjust 22.5 degrees for backsplash clearance. Adjust the handle position as desired. The innovative wave spring handle tension system prevents sagging and requires no adjustment.
- Check for Leaks: Once all connections are made, slowly turn on the main water supply and check for any leaks. Tighten connections as necessary.
