2. Use an adjustable wrench to disconnect the water-supply lines from the valves.
3. Disconnect the trap from the sink’s drainpipe using pliers.
4. Loosen the screws that hold the sink to the underside of the countertop.
5. Slide a putty knife under the rim of the sink to break its bond with the countertop.
6. Unplug the garbage disposer, and pull the sink from the countertop.
7. Place the new faucet onto the new sink. Tighten the locking nut to secure the faucet to the sink deck.
8. Slip the counterweight onto the spray hose, then connect the spray hose to the faucet.
9. Cut out and remove the existing PVC standpipe and trap for the garbage disposer.
10. Seal the old drainpipe with a rubber cap. Tighten the cap’s stainless-steel hose clamp with a nut driver.
11. Set the new sink into place, then from below, use a screwdriver to tighten each mounting clip.
12. Connect the water-supply lines to the hot- and cold-water shutoff valves.
13. Put plumber’s putty around the flange on the garbage disposer’s throat fitting, then press the fitting down into one of the sink’s drain holes.
14. From below the sink, slip two adapters and a lock ring onto the throat fitting.
15. Use a screwdriver to tighten the three screws on the lock ring.
16. Install a gasket and basket strainer into the remaining drain hole. Tighten the lock nut from below with pliers.
17. Scrape away the excess putty that squeezes out from beneath the throat fitting and basket strainer, and save for reuse on another job.

20. Run PVC pipe from the sink trap to the tailpiece that protrudes down from the sink’s basket strainer.
21. Install a T-fitting and PVC pipe to span from the drainpipe to the disposer. Trim the pipe to length, if necessary, with a PVC cutter.
22. Connect the drainpipe to the T-fitting with a compression fitting.
23. Tighten the two screws on the yoke to secure the opposite pipe end to the side of the disposer.
24. Connect the discharge hose from the dishwasher to the port protruding from the disposer.

    If you're cutting PVC with a hack saw and not a PVC cutter you should wear a mask. That stuff is toxic if you inhale it!

    it is very informative and I watch their video a lot, however, it would be nice if they had given the name of the manufacturer of the sink they used

    Any idea what the pad is that Richard is using? I've searched and found one, but it's not the same, doesn't seem as good as the one Richard is using.

    Richard makes a big deal of the mat, and then never uses it again after the first segment.

    Why the handsaw for cutting the old drain? Join us in 2021 with cordless oscillating tool, works effortlessly and…..its a disposal not a disposer…lol….and also absolutely love the girly pad for comfort!

    Why not install the drain/basket assembly and disposal while the sink was not yet installed like he did with the faucet? That would have avoided one less time in squeezing oneself under the the sink.
