Once the sink is firmly fastened down, install the sink strainer or if you have a garbage disposal, install the garbage disposal sink flange and mounting ring. The sink strainer / basket assembly and the disposal sink flange will mount in a similar manner. You'll seal the sink opening with a bead of plumber's putty around the opening about 1/2" in thickness. Place the new disposal sink flange or sink strainer assembly into the sink opening and press it into the plumber's putty. Tighten from below until the putty squeezes out and the flange is tight against the sink.
Now hook up the waste drain lines and water supply lines. Make sure the threaded connections are tight and be sure to use teflon tape on all threaded connections to prevent leakage. Turn on the water supply and check for and correct any leaks.
Once the plumbing connections are made, plug the garbage disposal into the electrical outlet and test for proper operation.
That's it, you're all done. Now enjoy that beautiful new sink and faucet!
