Step-by-Step Guide
Connect the Disposal Unit
- Determine the sink drain location: Measure the distance from the drain opening to the bottom of the sink. Subtract 1 inch for the disposal unit’s flange.
- Cut the drain pipe: Cut the drain pipe at the determined measurement using a hacksaw.
- Install the disposal unit: Apply plumber’s putty to the bottom of the disposal unit’s flange and secure it to the drain pipe.
- Connect the dishwasher drain hose: Use a hose clamp to connect the dishwasher drain hose to the disposal’s dishwasher inlet.
Connect the P-Trap
- Assemble the P-trap: Screw the tailpiece (the short end of the P-trap) into the disposal’s drain outlet.
- Insert the trap arm: Slide the trap arm (the longer end of the P-trap) into the tailpiece.
- Connect the drainpipe: Connect the other end of the trap arm to the sink drainpipe.
Install the Sink
- Apply plumber’s putty: Apply a generous layer of plumber’s putty around the sink flange.
- Place the sink: Center the sink over the drain opening and gently press it into place.
- Tighten the sink strainer: Thread the sink strainer onto the tailpiece and tighten it by hand.
Connect the Supply Lines
- Identify the supply lines: Determine which supply line is hot and cold.
- Wrap Teflon tape: Wrap several layers of Teflon tape around the threads of the supply line connectors.
- Connect the supply lines: Screw the supply lines into the corresponding valves under the sink.
Troubleshooting
- Leaks: If you notice leaks around the disposal or P-trap, retighten the connections or apply additional plumber’s putty.
- Clogs: If the disposal or dishwasher drain is clogged, use a drain cleaner or call a plumber.
