How to Install a Pedestal Sink · Step 1 of 7

Begin by locating the hot and cold water shut-off valves under the sink. Use a flathead screwdriver to turn the valve slots perpendicular to the pipe, shutting off the water flow. Next, position a basin wrench or faucet tool onto the mounting nuts securing the old faucet from below and turn to loosen them. Once loose, use pliers to loosen the supply line nuts from the shut-off valves. Finish unscrewing all connections by hand. With everything disconnected, go to the top of the sink and lift the entire old faucet assembly out.
Goal: Plumbing Fixture Repair
- Ensure the water is completely shut off before disconnecting any lines to prevent water damage.

FAQs
Why is wall blocking necessary for a pedestal sink, and what type of wood should I use?
Wall blocking provides crucial structural support for the sink basin, which often doesn't have a vanity beneath it and must bear its own weight. Use a sturdy piece of lumber like 2 in. x 8 in. Prime Lumber, ensuring it's securely fastened horizontally between wall studs to prevent the sink from pulling away from the wall over time.
The project estimates 12 hours; what factors contribute to this longer installation time for an intermediate project?
The 12-hour estimate accounts for several factors beyond simple assembly, including the time-consuming process of removing an old sink and potentially repairing the wall. Locating studs, installing robust wall blocking, and carefully running new PEX water lines can add significant time. Additionally, waiting for caulk to cure before final use is essential for a leak-free finish.
What are the most critical steps to ensure a leak-free plumbing connection for my new pedestal sink?
Always apply thread sealant tape (Teflon tape) to all threaded pipe connections before tightening. For the PermaFLOW ABS Slip Joint P-Trap, ensure all slip-joint nuts are hand-tightened, then given an additional quarter turn with Channellock pliers. Double-check all connections by running water and visually inspecting thoroughly for any drips before proceeding to caulk.
How do I ensure the sink basin and pedestal are perfectly level and securely mounted to prevent wobbling?
During the 'Dry Fit' step, use a level to mark precise mounting locations for the basin, ensuring it's plumb and level before drilling. Secure the basin firmly to the wall blocking using #10 3” wood screws. Position the pedestal directly beneath the basin's drain tailpiece, using shims if necessary to achieve perfect stability on uneven floors.
