Kitchen Faucet Won't Swivel

If you find that your kitchen faucet won't swivel as it should, you're not alone. A non-swiveling faucet can be a frustrating issue to deal with, as it hinders the convenience of your daily kitchen activities. There are a few common reasons behind this problem. One of the main culprits is often a build-up of mineral deposits or debris in the faucet's swivel joint. To address this, you can try cleaning the joint or, in more severe cases, replacing the swivel mechanism. Additionally, a loose or damaged handle or cartridge may also affect the faucet's swiveling capability. Ensuring regular maintenance and addressing any of these issues can help restore your kitchen faucet's swivel function, making your daily tasks in the kitchen much smoother.

Stripped Faucet Handle

A stripped faucet handle occurs when its threads have been corroded or worn down over time. This can cause the handle to lose its grip on the stem, leaving you unable to control the water flow.

A stripped handle can be fixed by either replacing the handle’s stem or consulting a professional. If the handle is corroded into the faucet, it’s best to call a professional plumber to remove it and inspect for any stripped threads.

Sometimes, you might need to replace the entire faucet if replacement handles are not available for older models.

Damaged Stem or Cartridge

The stem or cartridge is the internal component of the faucet that enables its operation, and it’s connected to the faucet’s stem, which is in turn connected to the handle. If the faucet stem or cartridge is damaged or worn, it can cause the faucet to malfunction and not stay in the off position. The remedy for this issue is to replace the damaged stem or cartridge.

However, replacing the cartridge independently can have risks; if the process is conducted improperly, you may damage the water supply pipe, leading to a more costly repair. In this case, consulting a plumber is a safer option.

Worn Rubber Washers

Rubber washers are used in faucets to create a watertight seal, ensuring a functioning washer. Over time, these washers can become worn or deteriorated, causing the faucet to leak or not turn off properly.

To fix this issue, you’ll need to examine and replace the handle’s stem as necessary. Replacing worn rubber washers ensures that your faucet functions properly and prevents water waste.

Identifying Your Single Handle Kitchen Faucet Type

Before embarking on the repair, it’s vital to know your faucet’s type as different faucets need varying repair techniques and replacement parts.

There are four main types of single handle kitchen faucets:

  1. Compression faucets
  2. Cartridge faucets
  3. Ball-type faucets
  4. Ceramic disk faucets

By understanding the type of faucet you have, you can determine the appropriate repair method and source the correct replacement parts.

Compression Faucets

Compression faucets are often found in older homes and utilize a washer to regulate water flow. When the faucet handle is tightened, the washer compresses against a valve seat, stopping the water flow.

To fix leaks in compression faucets, you’ll need to replace the washers and O-rings. This type of faucet is relatively simple to repair, making it a good starting point for DIY repairs.

Cartridge Faucets

Cartridge faucets use O-rings for their operation and are generally easy to maintain and repair. If you experience leaks in a cartridge faucet, you’ll need to replace the O-rings and cartridges.

Because cartridge faucets have fewer parts, they are typically easier to work with than other faucet types, making the faucet cartridge a convenient choice.

Ball-Type Faucets

Ball-type faucets are a type of washerless faucet commonly found in kitchens. They feature a single handle connected to a ball-shaped valve mechanism, which regulates the flow and temperature of the water.

To repair a leaking ball-type faucet, it’s best to replace all of the components simultaneously using a repair kit. This ensures that all parts are new and working correctly, preventing future issues.

Ceramic Disk Faucets

Ceramic disk faucets utilize a ceramic disk to regulate water flow and are known for their durability and reliable performance. To repair a ceramic disk faucet, you’ll need to either repair or replace the water valve seats.

These faucets are relatively easy to maintain and repair, making them a popular choice for modern kitchens.
