Carefully place the drain assembly with the fresh putty into the sink drain opening from the top. Press down firmly to seat it. From underneath the sink, slide the rubber gasket up against the sink bottom, followed by the cardboard friction ring. Finally, thread the large locknut onto the drain assembly and tighten it by hand. To fully secure it, use a screwdriver and hammer to gently tap the locknut clockwise until it is snug. This will squeeze the plumber's putty out around the top, creating a tight seal.
Goal: Secure the new drain assembly in the sink
- Have someone hold the drain in place from the top while you tighten the locknut from below to prevent it from spinning.

FAQs
Do I really need all the specific tools listed, like the Hilti drill and Zircon stud finder?
For secure and accurate installation, a stud finder is highly recommended to ensure the basin is mounted to wall studs, preventing wobbling. While the Hilti drill is powerful, any corded hammer drill with appropriate masonry bits can work for drilling into tile or plaster if studs aren't accessible or for floor mounting, but ensure it's capable of making clean holes.
What's the most critical safety precaution to take before starting this pedestal sink installation?
The most critical step is to turn off the water supply to the entire house or at least the bathroom you're working in. This prevents accidental flooding when disconnecting old fixtures or if a new connection leaks during testing. Always double-check that the water is off before proceeding with any plumbing disconnections.
How long should a beginner expect this project to take, and what's a common time-consuming step?
For a beginner, plan for a full day (6-8 hours) for this project, especially if you're unfamiliar with plumbing. Removing the old sink, particularly if it's heavily caulked or secured, can often be the most time-consuming initial step. Take your time, as rushing often leads to mistakes.
What's the most common mistake beginners make that causes leaks after installation?
The most common mistake is not properly tightening or sealing the P-trap and water supply connections. Ensure all threaded connections are hand-tightened, then given an additional quarter to half-turn with pliers or a wrench, and always use plumber's tape or pipe dope on threaded water supply connections for a watertight seal.
