## How to Replace a Kitchen Sink Basin
Replacing a kitchen sink basin is a relatively simple plumbing project that can be completed in a few hours. By following these step-by-step instructions, you can save yourself the cost of hiring a plumber.
### Before You Start
Before you begin, gather the following tools and materials:
– New sink basin
– Basin wrench
– Adjustable wrench
– Plumber’s putty
– Caulk gun
– Caulk
– Sponge
– Bucket
– Utility knife
### Step 1: Turn Off the Water Supply
The first step is to turn off the water supply to your sink. This is typically done by turning off the valves located under the sink. If there are no valves, you will need to turn off the main water supply to your home.
### Step 2: Disconnect the Drain
Once the water supply is turned off, you can disconnect the drain. To do this, simply unscrew the nuts that hold the drain in place. Be sure to place a bucket under the drain to catch any water that may spill out.
### Step 3: Remove the Old Sink Basin
Once the drain is disconnected, you can remove the old sink basin. To do this, simply lift the basin up and out of the countertop. Be careful not to damage the countertop or the basin.
### Step 4: Clean the Countertop
Once the old sink basin is removed, you should clean the countertop thoroughly. This will help to ensure that the new basin will fit properly and seal correctly.
### Step 5: Apply Plumber’s Putty
Before you install the new sink basin, you need to apply plumber’s putty to the rim of the basin. Plumber’s putty is a type of sealant that will help to prevent water from leaking around the basin.
To apply plumber’s putty, simply roll it into a snake-like shape and then place it around the rim of the basin. Be sure to apply the putty evenly and to press it firmly into place.
### Step 6: Install the New Sink Basin
Once the plumber’s putty is in place, you can install the new sink basin. To do this, simply lift the basin up and into the countertop. Be sure to align the basin with the drain hole.
Once the basin is in place, you can tighten the nuts that hold the drain in place. Be sure to tighten the nuts evenly and to not overtighten them.
### Step 7: Reconnect the Water Supply
Once the basin is installed, you can reconnect the water supply. To do this, simply turn on the valves under the sink. If there are no valves, you will need to turn on the main water supply to your home.
### Step 8: Test the Sink
Once the water supply is reconnected, you should test the sink to make sure that it is working properly. To do this, simply turn on the water and check for any leaks. If there are any leaks, tighten the nuts that hold the drain in place.
### Step 9: Caulk Around the Basin
Once you have tested the sink and there are no leaks, you can caulk around the basin. Caulking will help to seal the basin and prevent water from leaking out.
To caulk around the basin, simply apply a bead of caulk around the edge of the basin. Be sure to apply the caulk evenly and to press it firmly into place.
Once the caulk is in place, you can smooth it out with your finger or a wet sponge.
### Step 10: Allow the Caulk to Dry
Once the caulk is applied, you need to allow it to dry completely. This will typically take about 24 hours.
During this time, do not use the sink or get any water on the caulk.
### Tips
– If you are replacing a sink basin that is made of a composite material, such as Corian or Silestone, you will need to use a special type of caulk that is designed for these materials.
– If you are not comfortable replacing a sink basin yourself, you can hire a plumber to do the job for you.
