How to Lubricate Single-Handle Faucets


A door that makes a squeaking sound now and again is a common feature in many homes, but the last place you may expect to hear a squeak is in your kitchen or bathroom faucet. In the same way that lubrication is required for doors, faucets that squeak or are difficult to operate need it as well. Even though lubricating a single-handle faucet is not nearly as simple as oiling a door hinge, applying a dab or two of grease that has been properly prepared to the appropriate areas can quickly restore the fixture to a state in which it operates in a smooth and quiet manner.

  1. Turn off the water supply to both the hot and cold sides of the faucet.

  2. Raise the handle of the sink faucet until it is in the “on” position. Take off the little cap made of metal or plastic that is covering the Allen screw that is fastening the handle of the faucet to the stem. Use an Allen wrench to turn the screw counterclockwise. To remove the handle, pull it off the stem. Put the screw cap and handle away in a secure location for later use.

  3. To remove the metal cap that covers the faucet ball, use an adjustable wrench to spin it clockwise and loosen the threads on the cap. Carefully remove the cap from the threads. Wrap a soft cloth around the base of the cap if it doesn’t have any flat surfaces for a wrench, then use a pair of adjustable pliers to gently loosen it. If the cap doesn’t have any flat surfaces for a wrench. The remaining portion of the cap should be unthreaded by hand.

  4. Remove the cam that controls the water and the rubber packing from the ball. To take the ball out of the body of the faucet, pull up on the stem where it is attached. To take the seats and springs out of the body of the faucet, use the point of a tiny screwdriver to pry them up and out of the hole. Put the components to the side. The majority of single-handle faucets with stationary spouts need to be disassembled no farther than this point in order to apply lubricant.

  5. To remove the spout from a swivel-type faucet, turn it clockwise and counterclockwise while simultaneously drawing it up and away from the body of the faucet. Put a very little quantity of silicon faucet grease on the two rubber o-rings that are located on the body of the faucet, as well as on the inside of the spout. Applying a little pressure while twisting the spout back into position will secure it. To ensure that the spout may move without restriction, rock it back and forth.

  6. After applying a little amount of lubricant to the rubber seats, position them so that they are sitting on top of the springs. By using a tiny screwdriver to guide the springs and seats back into the holes in the body of the faucet, you may reinstall them in their proper positions.

  7. Spread a little quantity of oil all over the ball as well as the rubber packing. First place the packing on top of the ball, then place the control cam in its place. Place the ball into the body of the faucet so that it sits atop the springs and seats. After ensuring that the springs and seats have not moved and that the tab on the cam has been properly inserted into its slot in the faucet body, press the cam, packing, and ball into the body of the faucet. While you are threading on the cap, you should keep the ball in place by the stem. Make sure the cap is on nice and tight. Put the handle on the stem, then screw the Allen head on as tightly as possible. Remove the screw cap and replace it.

  8. Make sure that the handle no longer squeaks or binds by moving it across the whole of its range of motion. Start the water, then look around for any leaks.

    For step-by-step instructions on how to take apart your particular brand and type of faucet, see the exploded diagram that comes with the product. In a general sense, applying some silicon grease to the moving components that are found on the inside of any faucet will prove to be beneficial. Examine each component of the faucet for any indications of damage or wear while it is still in its dismantled state. There are kits available that offer merely the seals, in addition to complete repair kits that include the sections that wear out the most often.
