Step 1 – Shut The Water Off
First thing you need to do is shut the water off. You can do this by turning both the valves to the right. If your house is older and doesn’t have the shut off valves, then you might have to shut off the water supplier directly.
Once the valves are shut, we need to open the faucet to get rid of any pressure and to ensure that there are no last drips of water.
The next step is to remove the faucet by detaching the water lines. Please use a bucket to catch the few drops of water which may fall from the lines.
Now you need to remove the mounting nuts of the faucet. Please do this carefully or you might end up damaging the sink or the faucet threads.
Carefully lift the old faucet off. Don’t pull it forcefully if it doesn’t come out. Instead go through the steps above once again to see if you have missed any.
Now its time to assemble your shiny new faucet following the manufacturers instructions. Since this is different for different brands, we won’t be able to provide an individual guide for each brand.
You can use either Plumbers putty or Silicone caulking depending on your faucet to seal it tight to your sink to prevent any leakage.
Place the new faucet on the sink, clean up any extra residue of Silicone or putty and proceed to tighten the mounting nuts
Now that the faucet is mounted to the sink, you need to re-attach the supply lines to shut-off valves (use a wrench if you need to tighten it, but don’t overdo it). This step is essentially the reverse of what you did while unmounting your old faucet. Once done, check the functioning of your new faucet and ensure that there are no leaks.
