Choosing Your Replacement Faucet

For every guide for how to install a kitchen faucet,you first need to gather the necessary replacement faucet. 

  • Take photos of your current kitchen faucet and take the measurements where the holes in the sink are situated. Use those photos and measures to help you when you are going to purchase a replacement faucet. You will be more comfortable to pick the one that fits on your sink. Select the one that has openings that align with those that are already on your sink or countertop. It should be the same measurements of your older faucet that fits the space and meets your needs. If your more aged sink or countertop has extra space, then the new faucet does not need it, so you can usually buy a hole cover for the same material as the faucet.
  • Suppose you want your new faucet spray that has pullout spray that comes from the faucet spout. Choose the one with a gooseneck that place downwards rather than straight up. Those faucets that are straight-up are famous for leakage. Those leaks will be another pain to solve, and it will run into your cabinet. It is usually late to find out the leakage of those faucets. 
  • Purchase the highest quality faucet within your budget. As higher qualities are more durable, it will last longer and less likely to leakage. In my opinion, the gooseneck type faucets are much better and usually better quality. Most high-quality faucet comes with a lifetime warranty for original buyers.

Always Turn Off the Water Supply Before Installing a Kitchen Faucet

Before you start how to install a kitchen faucet project, you will need to turn off the water supply for the existing faucet. Switch off the hot and cold water supply lines shut off valves connected to the underneath of the faucet. Turn off the valve by turning it clockwise, and you should not require a wrench for this. Open the faucet to reduce the water pressure and check any water coming from the faucet. 

If your faucet is at least a few years old, then you may find the valves stuck or rusted that will make them impossible to move. Apply some heat to the valve with a hairdryer that will effectively loosen the valve to close it. You can also use locking pliers to grip the valve and gently persuade it to the off position. Be aware before you apply excessive pressure on turning off the valve as you can break the valve, which will result in water shooting out and flooding the whole cabinet with water. Fixing that thing is another pain and cost you more money. 

Before you attempt to turn off the valve, you should better turn off the water valve’s main supply if it is not working. That is mainly situated inside a basement or crawlspace where the waterlines enter your home. If you still can not locate the main valve, you can always use pliers to turn off the meter’s water. That is often located in your yard under a small maintenance hole like the cover. 

Removing the Old Faucet is Often Difficult Than It Sounds

Once the water supply is shut off, remove the old faucet. Lossen up the nut that holds it in place that is underneath the sink and then pulls the faucet out of that holes. Unfortunately, it is not easier to do the task as the space underneath the sink where the faucet is attached is often narrow.

Because of the location, the area is pitch black. You will need a strong working light to light up the dark area and an adjustable wrench to loosen the nuts. If you see the shutoff valves, nuts holding onto the faucet can be stuck or rusted over years of usage. If you run into this issue, try to use a brush to remove as much corrosion as possible. Use a wire brush and the spray penetration oil-like liquid wrench on the nuts to melt the corrosion. 

It can take more than a half-hour to overnight for the oil to work. After that, if you try to loosen the nuts again with the wrench, they still won’t turn. Then you will have to cut it off with a reciprocating saw or a hacksaw after removing the faucet and clean up the grime or dirt from the sink surface. If you do not want to do or learn about how to install a kitchen faucet, then call a plumber at this point.
