The procedure

1. Disconnect all drain lines

The first step is to disconnect the P-traps and drain lines if they obstruct the access to water supply and faucet pipes. You can place a coffee can or bucket under that P-tra p instead.

2. Disconnect garbage disposer

The next step is to unplug your garbage disposer. If the disposer is wired directly, then shut off the main panel’s circuit breaker. Likewise, disconnect the discharge line of your dishwasher as well.

Also, when the disposer drops free, you might want to cushion the blow by placing a paint can with rags. Now, use a hammer to tap the disposer’s retaining ring. In the counterclockwise direction!

3. Shut off water supply

When valves are a part of the system, you need to shut them off from below your sink. Otherwise, cut off the primary water supply line. Then open your kitchen faucet to get rid of remaining pressure and water.

And in case you’re replacing or installing valves, cut off those water lines present under the fittings. You can do that by using a hacksaw or tube cutter.

4. Loosen the nuts

Now’s the time to get to the faucet’s tailpiece nuts located at the back of your sink. Fit the invaluable basin wrench behind it and turn in a counterclockwise motion to initiate loosening. This allows you to easily disconnect the nozzle hose and remove that faucet.

At this point, you might want to clean the area before fixing the new faucet flange.

5. Install the flange

All faucets come with preassembly instructions. So follow them and position the new flange on top of the opening of the faucet. Then use your fingers to tighten the nuts below the sink.

But don’t forget to check the flange, sinkhole, and faucet alignment before you move on to the next step.

6. Tighten the mounting nut

Just to make sure that you’re not doing it the wrong way, check the handle and faucet operation. Thread those feeder lines into the sink and flange holes before slipping on the washer. This is when you need to tighten those mounting nuts from underneath.

At such times, you might want to achieve more tool clearance. So if that’s the case, gently spread the supply lines if necessary.

Next, use the open-end wrench tool to tighten the nuts. Please note that this wrench allows you to make only 1/6th of a revolution at a single time. So be patient at this point.

7. Attach spray hose

The time has arrived to thread the nozzle into the body before threading the hose into the supply tube. Tighten the latter and then pull out the nozzle from the faucet. This particular action ensures that the hose below your sink operates without any restrictions.

Finally, hook up the counterweight based on your manufacturer’s instructions.

8. Mark supply lines

Now you can tighten the newly installed valves before marking feeder lines above those compression nuts. For the cut-off action!

9. Connect supply tube to supply lines

Use sandpaper to clean copper tubing. Then place the valve body, compression ring, and nut on top of the pipe. Now tighten them.

Now it’s safe to close that valve and start the primary water valve. Look for leaks at this point. If everything seems to be in place, you can reassemble the drain lines, P-traps, and garbage disposer.

Even though long, the process is not as complicated as you might expect it to be. And if you follow these instructions, the task becomes easier than you can imagine. So this is how to replace a single handle kitchen faucet. Or any other type of a faucet for that matter!
