How to Repair a Compression Faucet?

Although compression faucets are a typical feature in many homes, any homeowner may benefit from knowing how they operate and how to solve problems like leakage. We’ll examine what compression faucets are, the reasons behind their potential leaks, and efficient repair techniques in this article.

Understanding the compression faucet

A compression mechanism is used by a compression faucet to regulate the water flow. The hot and cold knobs on these faucets are usually independent and may be rotated to change the water’s temperature and flow rate. A compression stem located within the handle rotates up and down to open and shut the valve. The compression stem presses down on a silicone or rubber washer when the handle is twisted, forming a seal that halts the flow of water. 

The Reason Why Compression Faucet Leaks?

Compression faucets may eventually leak even with their straightforward design. Durability issues with the rubber or silicone washers are among the most frequent causes of leaks in compression faucets. As a consequence of the continuous friction created by the faucet’s usage, the washer may deteriorate or take on an irregular form, which might lead to a real problem.

Mineral accumulation is another possible reason why compression faucets leak. Minerals from the water might build up on the valve seat over time, making it difficult for the washer to maintain a tight seal. This may result in the faucet trickling or even running continuously when it should be off.

How to Repair a Compression Faucet

1 Switch off the water supply.

On the water line under the sink, look for a tiny shutdown valve (often with a handle shaped like a football). Close the valve by turning the handle clockwise. Turn off the water supply to the house at the main cutoff valve or the water meter if there are no shutoff valves under the sink. To relieve any pressure and leftover water in the pipe after the water has been turned off, completely open the faucet.

2 Remove the faucet’s handle.

A screw that is hidden behind a decorative cover secures the handle body to the faucet valve stem assembly. On older faucets, the handle is usually screwed into a metal cap. Using pliers, grasp the cap and remove the screw to expose the screw that holds the handle. Use a tiny flat-blade screwdriver to take off the cap if it is made of plastic.

3 Remove the faucet’s handle.

A screw that is hidden behind a decorative cover secures the handle body to the faucet valve stem assembly. On older faucets, the handle is usually screwed into a metal cap. Using pliers, grasp the cap and remove the screw to expose the screw that holds the handle. Use a tiny flat-blade screwdriver to take off the cap if it is made of plastic.

Metal caps on certain faucets may also be removed with force. How can one find out the finest way? It’s most likely a screw-off cap if the metal top has serrations all around it. The cap is prone to pry off if it is thin or has a smooth edge.

Apply a Phillips screwdriver to the screw holding the handle to the valve stem. To take the handle off the stem, pull it straight up. You may need to use a compression faucet handle puller to free the locked handle.

4 Remove the valve stem system and cover.

In the case of single-handle faucets, which are often seen on bathtubs and certain sink faucets, you may discover a cover over the valve stem assembly after removing the handle. Using pliers, remove the knurled knob that secures the valve stem assembly cover.

If the cover is missing, search for the valve stem assembly’s hex-nut portion, which is often found where the assembly joins the faucet body. To release the valve stem assembly, grasp this nut with pliers or an adjustable wrench and rotate it counterclockwise. Remove the valve stem assembly from the faucet body by fully unscrewing it.

5 Take out the Stem Washer.

On the lower part of the valve assembly, find the old washer seated in a valve seat. It is likely to be well-worn or misshapen and will be screwed into place. The washer’s brass screw should be removed. To remove the washer from the valve seat, insert a little flat-bladed screwdriver into the washer’s opening. To ensure a good fit of the new washer in the valve seat, clean the end of the washer holder of any leftover rubber or residues.

6 Select a Washer Replacement for the Old One

It could be necessary to purchase a variety of washers, which are often offered as a “faucet repair kit.” You may also obtain a new rubber O-ring for the valve stem assembly if you’d like.

Replace the washer by pushing it into the valve seat and tightening it with the brass screw. Replace the O-ring if necessary. Apply a little layer of waterproof plumber’s grease on the exterior of the O-ring, whether it is new or old.

7 Reassemble the faucet.

Using pliers to tighten it firmly, thread the valve stem assembly into the faucet body. Put the handle and cap back on. After turning on the water, be sure there are no leaks in the faucet.

Conclusion:

In conclusion, even though compression faucets are a popular kind of fixture seen in many houses, leaks may still occur with them. You can prevent water waste and even property damage by being aware of how these faucets operate and being able to fix them efficiently. It is possible to promptly and efficiently fix leaks in compression faucets and get them back up and running by following the instructions provided in this article.

What is the function of a compression faucet?

Compression stems, which are big diameter screws with a washer at the end that presses against a valve seat, are what enable compression faucets to function. Water flow is stopped when the compression is tightened because a rubber seal pushes up against the valve seat.

 what causes a compression faucet to drip?

A worn-out washer is the most typical cause of a compression faucet leak. The washer inside the faucet that cuts water flow when the handle is turned firmly shut wears down over time.

Does the compression faucet work with any kind of washer?

For your compression faucet to provide an adequate seal, make sure you use the right kind and size of the washer. There may be leaks or other problems if the incorrect washer is used. For help in choosing the right washer, go to the manufacturer’s instructions or speak with a plumbing specialist.

Why does the compression faucet still leak even after the washer has been changed?

After changing the washer, if your compression faucet is still dripping, there can be harm to the valve seat or other parts. Make sure the replacement washer is placed properly, and look for any indications of wear or mineral accumulation on the valve seat.

How can I determine if the faucet in my home is a compression faucet?

The hot and cold water knobs on compression faucets usually work independently, requiring many turns to open or shut the flow completely. This design indicates that your faucet is probably a compression faucet.
