Step One for Replace Kitchen Faucet: Buy a few parts from the hardware store

Before starting that plumbing activity, you will need to pick up a few key parts from the store. Chances are, you will need to visit the hardware more than a few times, and if you’re lucky, at least one.

Depending on the workings of your sink and your faucet, you may need to buy shutoff valves. Take a look at your sink and see if it has shutoff valves attached. If it does, you only have to make sure they are in working condition. If they’re not working, or if it does not have any, you must buy shutoff valves that are compatible to your pipes and attach them. You’ll know it works if your faucet no longer drips.

Next, a basin wrench may also come in handy. They are used for removing and installing hard-to-reach fasteners that hold the older faucet assemblies to the sink.

You should also buy new stainless steel supply tubes to replace your old ones. To do this, simply measure your existing supply tubes and buy new ones accordingly. These are designed to give years of great service, while moving around the tube obstacles in your plumbing system. This unique wrench lets you loosen and tighten nuts in spaces that are otherwise inaccessible.

There are also some cases when you will need to remove drain lines before you can reach the faucet. For this, you are going to need a pipe wrench or slip-joint pliers, depending on the drain line that has to be removed.

If you have to cut copper tubes, you need a conventional tubing cutter. Check if the copper supply lines are within a few inches of the back of the cabinet. If so, get yourself a special mini tube cutter.

Lastly, you will need a set of open-end wrenches for disconnecting and reconnecting water lines.

Now that you have these tools within your arsenal, you have to take a picture of the drain lines before disconnecting them, so you will know how to put everything back together when you’re done. Sketching the layout will also work.

It may work to your advantage if you schedule your faucet replacement during store hours, so you can always walk back and forth in case you need additional tools and parts.

Step Two for Replace Kitchen Faucet: Clear the path to your old faucet

Put away everything you have stored under the sink, placing them in a convenient spot so you can easily put everything back afterwards. It is easier to lie down on the floor facing the sink than sitting at an uncomfortable distance. Have something like a piece of plywood supporting your back while you do your hard work.

The next thing to do is assess whether you can reach the faucet right away. If you see a couple of things blocking your path, such as pipes and P-traps, then you may have to work a little harder.

Remove these pipes and traps. You can place them in a box, so you can bring them to the store and easily find replacements that match your old ones. If these pipes are made of plastic and you are careful with their removal, you may be able to reuse them.

Next, remove the garbage disposer by unplugging it and pulling it out of the cabinet. A hard-wired garbage disposer can be removed by shutting off the circuit breaker that controls the disposer, and then disconnecting it and setting it aside the electrical cable still attached.

Remove FaucetStep Three for Replace Kitchen Faucet: Remove the old faucet

Now that you have eliminated all the obstacles, you are free to take out your old faucet. The first step in doing this is to disconnect the water supply lines.

Turn off the main water supply valve connected to your house. Then cut off the pipes below the connections using either a tube cutter or a hacksaw.

Before turning the water back on, make sure the new valves you attached are closed. Next, use the basin wrench to loosen the old faucet and remove it. If you find difficulty in loosening the old nuts, you can try soaking them in oil. Keep repeating until you can get it off.

For clamp-down sinks, you can get it off by loosening the screws on the bottom of the sink rim. For a drop-in sink, you can cut the caulk between it and the countertop with a utility knife. Then you can lift out the sink and go for those nuts with a pipe wrench. This should let you free up your old faucet.

Install New FaucetStep Four for Replace Kitchen Faucet: Install the new faucet

As I mentioned in the beginning, the removal of your old faucet is much harder than installing your new one. For this, you must simply follow the manufacturer’s instructions so you could mount the new faucet smoothly.

After that, simply hook up all the water lines as previously arranged.

The final step is to put all your belongings back under the sink, and clean up, preferably with your newly-installed kitchen faucet. If you followed these easy steps, you should have no trouble enjoying the fruits of your labor.
