Turning off this switch will shut off the water supply of your sink or basin only. For better performance, you can turn off the main switch of the waterline of the whole house. It can be found in the basement or the switch board room.

All the bucket lines should be also turned off which are relevant to this water pressure. Apply the adjustable wrenches to separate the lines of this bucket also. Make ready a small bucket also to store the water if left in that water line. You can leave the sink attached to the bucket.

To remove the grimes, putty & caulk from the base of the sink countertop use a putty knife. Clean all the components to reinstall the new one as usual.
Steps for Installing a New Sink
Though you have removed the old sink yet so you can now clear all types of debris beside it. Make sure the measurement of the old sink & the new one is perfectly ok. Or the sink will not be well fitted with that gap.
Step – 1
If you find out that the new one is not well fitted with those previous measurements then use the jigsaw or tile cutter to make proper space. If the new size is smaller than the old one then what will you do? Use a piece of caulk to cover the gap. It can fill the gaps between ¼ inch with the surface body side. If your gap is larger than this size then bead of caulk & wait & wait until it is completely cured.
Step – 2
Remove from the countertop & attach the clips towards the sink bowl. Then you need to install the components of all faucet lines. Put some plumbers putty around the strainer & install it by pressing against the putty.
Step – 3

Step – 8
Here the pipe of disposer discharge is waiting for you. With the drainage pipe & the P trap pipe, you need to reconnect it. If the drainage pipeline is not perfectly connecting with your old pipeline then you can make some adjustments. It can be too long or too short from the sink line. So measure the required length of pipe. Adding a little bit extra length can help you to get a perfect measurement. Before cutting the pipe wear the safety glasses.

After checking all connections you can power on the disposer then the waterline. Check whether there is any leakage or not.
