How to Rough in sink drains and supply lines?

Step 1: Determine the location of the sink

The first step is to determine the location of the sink. This will help you determine the length of pipe and fittings you will need.

Step 2: Cut the drain hole in the sink

Use a hole saw to cut a hole in the sink for the drain. The hole should be 1-1/2 inches in diameter.

Step 3: Install the drain flange

Place the drain flange over the drain hole and secure it with the included screws.

Step 4: Install the P-trap

The P-trap is a U-shaped pipe that helps to prevent sewer gases from entering the sink. Connect the P-trap to the drain flange using slip nuts and gaskets.

Step 5: Connect the supply lines

Connect the hot and cold water supply lines to the faucet. Use compression fittings to secure the lines to the faucet.

Step 6: Test the drain and supply lines

Turn on the water and check for leaks. If there are no leaks, you are finished!
