How to install a faucet and reinstall garbage disposal for countertop replacement
What happens here
First, take the garbage disposal unit and align its three mounting tabs with the corresponding ramps on the mounting ring under the sink. Lift the disposal into place and twist it clockwise to engage the tabs onto the ramps, locking the disposal into the mounting assembly. The presenter explains that this acts like going up a ramp. Once seated, use a large pair of channel lock pliers or a disposal wrench to further tighten the mounting ring by twisting it until it's fully cinched down and snug against the sink's underside. The presenter emphasizes that it should be tight enough that it cannot be easily removed by hand. Next, assemble the new 1 1/2-inch P-trap (if not already assembled). Connect the P-trap to the disposal's drain outlet (the side port). Secure this connection loosely with its compression nut and washer. Then, connect the other end of the P-trap to the previously installed ABS trap adapter on the wall drain, again securing it loosely first to allow for adjustment. Ensure the disposal's drain plug is removed from the disposal's side port before connecting the P-trap.
Goal: The garbage disposal unit is attached to the mounting assembly, the new P-trap is connected, and all drain connections are secured.
