ATTACHING DRAIN OUTLETS

A drain outlet attachment to a lavatory/sink is the first step in installing the fixture's draining system. The drain outlet hookup is a combination of parts that are assembled to the lavatory/sink. The two types of attachments are the pullout (PO) plug type and the popup type.

Pull-out (PO) type of outlet attachment. Use the following steps for PO type outlet attachment (see Figure 8):

  2. Press the flange down to spread the plumber's putty.
  3. Slip the rubber washer and the metal washer over the drain body under the fixture.
  4. Screw the locknut clockwise into the drain body.
  5. Wipe off all excess plumbers putty from around the flange.
  6. Apply pipe compound to the threads of the drain body, and screw the tailpiece on the drain body.

Pop-up type of outlet attachment. Use the following steps to attach a pop-up drain (see Figure 9):
