Properly configuring the hookups for your washing machine is vital to avoiding leaks. Most of the outlets on Oatey's outlet boxes come with plastic pieces you have to remove so that pipes can be hooked up. If your Oatey washing machine outlet box has yet to be installed, clamp it down onto a workbench or have a friend hold it, as you will need both hands free and don't want the box to move around. If the outlet is already installed, it should be mounted securely enough that you can remove the plastic piece without assistance.

Step 2

Line up the tip of a flat-head screwdriver with the edge of the circular plastic piece you want to remove from the Oatey washing machine outlet box.

Step 3

Hammer lightly on the butt of the screwdriver and move slowly around the edge of the plastic piece to break the seal. Stop when you've broken the seal approximately three quarters of the way around the circle. Do not break the seal all the way around the plastic piece, or it will fall into the drain.
