  • Coldwater valve
  • Hot water valve

You will find these valves at the back of your Moen kitchen faucet. There might be some difficulties to reach on it without proper lighting. Hence, you can use a flashlight to do this work.

After you get the water supply valves of the faucet, shut off both valves by rotating several times in an anticlockwise direction.

Always keep in mind that you need to close the valves perfectly. Otherwise water might be dripping on you while working. This leaking water can be a cause of disturbance during your work and you won’t be able to tighten the loosen faucet properly.

So, after turning off the kitchen faucet supply line valves, turn on the handle of the faucet again and ensure that the water supply is shut off properly.

Step 3: Turn On The Valves To Release Pressure

After turning off the water supply valves, open the Moen kitchen faucet handle to release any pressure in the water supply lines.

Now let’s get to the loose handle part

Step 1: Clear The Sink Area And Turn Off The Water Supply Lines

At first, clear the sink top area and remove everything from there so that nothing hampers your work.

After cleaning the top of the sink, turn off the water supply lines to ensure that no water is dripping out from the lines during work. Definitely, you won’t want to see a flood in your kitchen, right?

We have told you in our previous sections where and how you will get the water supply valves to turn them off. So, we will not explain the same info here again.

Step 2: Check Your Kitchen Faucet Handle

Now, check your Moen kitchen faucet handle carefully that what mechanism it has. There is some difference in setup between a utility sink faucet and a Moen kitchen faucet. So, you should check the setup of your Moen faucet before any repair work.

You will notice two things depending on which types of Moen kitchen faucet you are using.

  • A screw or hex nut attached to the end of the faucet
  • A cap on the top of the kitchen faucet handle.

Step 3: Remove The Plastic Screw Or Hex Nut From The Handle

Now, when you see deeply in the handle of the kitchen faucet, you will notice that at the entrance of the faucet handle, a hex nut or a little screw is settled.

You can just use your fingernail or a little tool, like- mini knife to gently unscrew that out. It will feel to you like a loose plastic that you can easily remove from the kitchen faucet handle. You need not more than a minute to remove the nut.

Step 4: Locate The Hidden Setscrew Under The Decorative Cap

Now the tricky part of your work comes. Here you need to locate the setscrew that is hidden under the decorative cap. It’s not easy work to do only with your hand.

So, you need a proper tool to do it. You can use a screwdriver and pliers to do the job, but we recommend an Allen wrench for this work.

You can use an Allen wrench which will be enough to reach under the handle cap and make your work easier. But the size of an Allen wrench is important to consider, so find the proper size of an Allen wrench that will fit into the handle screw.

We vote for 3/32 sized Allen wrench for your work that is more comfortable to use than any other size.

The hard part of the work is to find the actual screw. So, if you enter the Allen wrench straight up inside the cap and don’t find the screw, try a little bit of angle direction.

When your Allen wrench head will find the screw, you will feel it on your hand.

Step 5: Tighten The Setscrew With The Allen Wrench

After finding the setscrew, you need to twist it in the clockwise direction to tighten it.  You don’t need to turn it for a long time, just a couple of clockwise turn is enough to tighten the loose kitchen faucet handle.

Keep in mind that you shouldn’t be tightening the faucet handle too much because it will be hard for you to open the handle when you start to use it. So, keep twisting the screw until your Moen kitchen faucet handle is tightened enough.

Step 6: Reconnect The Water Supply Valves

After tightening the handle, connect the water supply valves again with the kitchen faucet. Open the faucet handle to start the water flow and check the smoothness of water. Also check the tightness of your handle.

If all is Ok, your work is over.
