Setup & Installation
Professional installation is recommended. Ensure all local plumbing codes are followed. Before starting, turn off the main water supply to the bathroom.
Preparation:
- Clear the area under the sink.
- Remove the old faucet and clean the sink surface.
- Gather necessary tools (e.g., adjustable wrench, plumber's putty or silicone sealant, screwdriver).
Installation Steps:
- If your sink has three holes, place the optional deck plate over the holes. Apply a thin bead of plumber's putty or silicone sealant around the base of the faucet or deck plate to ensure a watertight seal.
- Insert the faucet body through the hole(s) in the sink/deck plate.
- From underneath the sink, secure the faucet using the provided mounting hardware. Ensure the faucet is aligned correctly before tightening.
- Connect the flexible supply lines from the faucet to your hot and cold water supply valves. The lines are typically marked for hot (red) and cold (blue). Ensure connections are tight to prevent leaks.
- Install the included non-metal push-down waste assembly (drain assembly) according to its specific instructions, ensuring a proper seal with the sink drain opening.
- Once all connections are secure, slowly turn on the main water supply and check for any leaks.
- Test the faucet's operation, checking both hot and cold water flow and temperature control.
Operating Instructions

Water Flow and Temperature Control:
- To turn the water ON, lift the lever handle upwards.
