Preparation and Installation Learn how to install a pedestal sink. From "Ed the Plumber" episode DETP-306

(Continued from page 1)

Mounting the Pedestal to the Floor

The pedestal sink must be mounted to the floor for stability. The technique for doing this will vary depending on the type of floor you have.

• If you are drilling into concrete, use a hammer drill and a concrete bit. Simply add a lag screw, and then snug it down with a ratchet. Be sure not to over-tighten.

• If your floor is tile, use a tile bit to drill the holes. A tile bit has a head like an arrowhead. Drill into the grout line if possible to prevent damage to the tile.

Note: Don't apply sealant around the base of the pedestal. It could damage the floor if you ever need to move the sink.

Dressing the Sink

"Dressing" the sink simply means to put all of the hardware on the sink before installation.

1. Install the spout and handles (figure E). Use a roll of plumber's putty around the seal to make sure it's water tight.

2. Insert the valve bodies into the proper mounting holes, ensuring that the valve body marked "cold" is installed to the right of the center hole. Once the valve body is in place, slide the metal washer and nut onto the base, and then tighten it down.

3. Place the seal ring over the spout body, and then insert the spout into the sink. Place the metal washer and nut onto the spout shank and tighten the nut with a wrench.

4. Install the hot water valve in the same way you installed the cold. Don't forget to use plumber's putty.

5. With the hardware mounted on the topside of the sink, mount the supply lines underneath the sink.

6. Screw the supply tee to the bottom of the spout, and then tighten it up with a pair of slip joint pliers (figure F).

7. Attach the flexible supply lines to the hot and cold valve bodies, and then attach them to the supply tee.

8. Connect both the hot and cold flexible supply lines to each of the valve bodies, tightening each one with a wrench (figure G).

Pop-up Assembly Installation

1. Apply a generous amount of plumber's putty around the base of the flange, and then place the flange in the sink.

2. Place the nylon o-ring and nut over the flange. Tighten with slip-joint pliers.

3. Attach the drain body to the flange, ensuring a tight seal (figure H).

4. Use Teflon tape around the threads of the tailpiece to prevent the drain assembly from leaking.

5. Screw the tailpiece to the drain body.

6. Attach the connecting rod to the drain body, and then connect the stopper rod from the back of the faucet to complete the drain assembly (figure I).

7. Set the lavatory on the pedestal so that the hanger bolts extend through the lavatory holes.

8. Install the cap nuts and washers, and then tighten.

9. With the sink mounted, connect both the hot and cold water connections. Tighten with slip-joint pliers.

10. Secure the end of the p-trap to the tailpiece of the drain assembly. Connect the p-trap to the tailpiece by screwing it into place using the threaded connection (figure J).

11. Turn the water on at the main.

12. Turn on the water heater.

13. Open the faucet at the new sink, and then check for leaks.
