Installing and replacing a kitchen sink is fairly simple, but it's recommended to install the sink with two people.

NOTE: This is a drop-in style sink. Other types of kitchen sinks would require different steps.

Step by Step Instructions

Step 1:

Loosen the silicone and older sink with the putty knife.

Step 2:

Remove the older sink.

Step 3:

Remove all of the old silicone using the putty knife.

Step 4:

Add a rim of new silicone caulking.

Step 5:

Add the new sink. Since this one is cast iron, no clamping is needed because the sink weighs enough.

Step 6:

Add plumber's putty to the new drain and insert the drain into the sink.

Step 7:

Once the drain is set in the sink hole, you will want to put the drain together in the following order: rubber gasket, washer, nut. Then, secure the drain to the sink.

Step 8:

Connect the plumbing to the drain. First, connect the tail piece to the drain basket, and then connect the drain line to the tail piece.
