Replacing a traditional faucet—hot and cold handles on both sides of a spout head—with a waterfall faucet in your bathroom renovation project can be undertaken as a do-it-yourself project by following a few pointers.

Step 1 – Preparation

Make sure that the old sink has been completely removed properly before proceeding. Your work area should be free of any obstructions that could impede you completing the project successfully.

Step 2 – Water Line Connection

Connect the hot and cold water supply lines from the wall to your faucet assembly. The assembly will accept all standard screw-on fittings with the traditional layout for hot on the left and cold on the right. After you have connected both and turned then as tight as possible by hand, fully tighten each with your pliers.

Step 3 – Rubber Over Brass

Make sure to place a rubber washer over all brass ones when inserting a mounting screw into the gasket hole.

Step 4 – Water Line Through Vanity

Feed each water line through the corresponding holes from underneath the vanity top.

Step 5 – Mount the Faucet Assembly

While holding the faucet assembly above, secure it to the mounting screw from below through the appropriate hole. Make sure the rubber gasket makes contact with the underside of the vanity. Once you have the faucet assembly secured and stable you can let go.

Step 6 – Other Mounting screw

There will be a second mounting screw hole where you will thread the other. Make sure to tighten both waterfall faucet assembly mounting screws securely.

Step 7 – Connect Water

Connect each water line to the appropriate control valves – hot is on the left while right is on the right. Tighten the lines securely.

Step 8 – Drain

Place the basin in the vanity hole and place the drain in the hole. Attach the drain locking nut from underneath making sure it is firmly fastened against the basin bottom to prevent a leak-proof fitting. Place the drain spacer ring around the fitting and against the basin bottom. The spacer ring may or may not have screw threads for securing. If not, you need to hold it in place.

Step 9 – Set Drain in Hole

Place the drain fitting in the vanity drain hole making sure the spacer ring stays in place between the basin and the vanity.

Step 10 – Fasten Drain Assembly

Place the locking nut and washer on the threaded drain fitting and secure the drain to the bottom of the vanity that will hold the basin in place. Attach the drain pipe to the fitting.

Never over tighten the water supply lines from the house to the sink. This my damage the fitting ends causing leaks.
