A brand new kitchen sink can improve both the functionality and aesthetics in your kitchen. If you’re considering a DIY for sink installation, you’ll be pleased to know it’s not as difficult as it seems. The following is a guide for how you can complete the installation stress-free.
Measure the sink
The first step is to measure your old sink. The idea behind this isn’t just to ensure your new sink will slot in, but it will also show you the exact position of the drains. If your new sink doesn’t match the old sink’s dimensions, you’ll need to make adjustments once it’s installed.
The hardware
Do you want to replace any of the existing features? Choose your hardware ahead of time because if you do place to switch your fixtures out, then it should be taken care of when you install the new sink. If you want to install a soap dispenser, a hot water sink, or a filtered water tap, then you may need to drill additional holes in your sink. The majority of sinks come with one to four pre-drilled holes. You should avoid altering your sink by purchasing one that comes with the correct number of holes for the additional fixtures you plan to install.
Old sink removal
Now it’s time to ditch your old sink!
Water off: Every water supply running to the sink should be turned off. They should be located directly below your sink. If you aren’t sure where the valves are and you haven’t successfully traced them, turn off your main water supply. It’s always better safe than sorry. Additionally, before you disconnect anything, it is wise to snap an image of the pipe and valve configuration. That way, when it’s time to reconnect the lines during the installation of the sink, you can refer back to it to ensure you get it right.
Faucet on: This will relieve water pressure and clear the waterline.
Disconnect: Grab a wrench, get a bucket, and disconnect the supply and disposal lines. The bucket can be used to catch any water. Once complete, you can turn off and then unplug the disposal circuit. You will then need to detach the p-trap, drain it, and leave a bucket to collect the remaining drips. To remove the disposal, you will need to follow manufacturer instructions.
Loosen: Beneath the sink, you will find clips holding it in place. These can be easily removed with a screwdriver. Use a razor to cut caulking away from around the sink.
Remove: Now all you need to do is give the sink a push from beneath until you can separate it from the countertop. If it still won’t budge, double-check the caulking and clips (they should face the bowl of the sink).
New sink installation
After all that, you might be surprised to learn this is the easy part.
The new fit: The new sink should be placed into the existing hole to ensure the fit is right.
The clips: Now that your sink fits the countertop, you can attach the clips. The sink will need to be flipped for this.
The strainer: For this task, you will need a plumber’s putty. Roll it to form a thin strip and apply it around the edges of the strainer and drain. Place your strainer in the drain while you press inwards.
The gaskets: You will want to move your sink into a sideways position for this task. Add rubber gaskets to your brain and thread the flange until all of your drains are covered and remove excess putty.
The sink: Screw in the sink’s mounting bracket, apply caulk beneath the sink and lower it into position. Once it is squarely aligned, you can rotate the clips toward the bowl to secure it in place. You can then caulk the outer area of the sink to seal it. A damp cloth should suffice to wipe excess caulk away.
The fixtures: Finally, you can reattach the disposal lines and water supply. Don’t forget to attach any additional fixtures you planned. The last job is to connect the p-trap. Now you can turn on the water supply.
If you’re not sure about how to reattach these fixtures, or you have any other problems with the above methods, call in the professionals. While the job is simple enough, even a simple mistake can result in serious damage.
