How To Change The Bathroom Sink

How to Change a Bathroom Sink

Replacing a bathroom sink is a relatively simple plumbing project that can be completed in a few hours with the right tools and materials. Here's a step-by-step guide to help you get the job done: ### Tools and Materials You'll Need: * New bathroom sink * Adjustable wrench * Plumber's putty * Screwdriver * Basin wrench * Tape measure * Level * Utility knife * Caulk * Sponge or cloth ### Step-by-Step Instructions:

1. Shut off the water supply:

Start by turning off the water supply to your bathroom. Locate the shut-off valves underneath the sink and turn them clockwise until the water stops flowing.

2. Disconnect the water lines:

Use an adjustable wrench to loosen the nuts connecting the water supply lines to the faucet. Be careful not to overtighten or cross-thread the nuts.

3. Remove the old sink:

Place a wet cloth or towel around the base of the sink to prevent scratching the countertop. Support the sink with one hand and use a screwdriver to remove the screws holding it in place. Lift the sink straight up and out of the hole.

4. Clean the countertop surface:

Use a sponge or cloth to clean the surface where the sink will be installed. Remove any old caulk or debris.

5. Apply plumber's putty:

Roll out a rope of plumber's putty and place it around the drain hole in the countertop. Smooth it out with your fingers to create a seal.

6. Position the new sink:

Place the new sink into the hole and center it. Press down firmly to seat it against the plumber's putty.

7. Secure the sink:

From underneath the sink, insert the washers and screws that came with the sink. Hand-tighten the screws until the sink is snug, but do not overtighten.

8. Connect the drain:

Place the drain flange over the drain hole and tighten it with a basin wrench. Make sure the gasket is in place and creates a tight seal.

9. Reconnect the water lines:

Align the water supply lines with the corresponding connectors on the faucet and tighten the nuts with an adjustable wrench. Turn on the water supply and check for leaks.

10. Caulk around the sink:

Apply a bead of caulk around the edge of the sink where it meets the countertop. Smooth out the caulk with your finger or a caulk tool. This will prevent water from seeping into the gaps.

11. Allow the caulk to dry:

Let the caulk dry completely as per the manufacturer's instructions. This may take several hours or even overnight.

Tips:

* Use a level to ensure the sink is installed evenly. * If you encounter any stubborn bolts or nuts, apply a penetrating lubricant to loosen them. * Wrap the jaws of the wrench with tape to prevent scratching the fixtures. * Test the sink thoroughly before using it to make sure it is functioning properly.
