Selecting Replacement Parts
The type of replacement part needed depends heavily on the faucet’s type and the source of the leak. Carefully examine the leaking faucet to identify the faulty component before purchasing replacements. For instance, a dripping faucet might require only a simple washer replacement, while a cartridge faucet with a persistent leak will necessitate a new cartridge.
Disconnecting the Water Supply
Before starting any repairs, it is essential to safely disconnect the water supply to the faucet. This prevents water damage during the repair process. Failure to do so can lead to flooding and significant water damage.
- Locate the shut-off valves under the sink. These are usually located on the water supply lines leading to the faucet.
- Turn the shut-off valves clockwise to completely close them. This will stop the water flow to the faucet.
- Turn on the faucet to relieve any remaining water pressure in the lines.
Repairing the Leaky Faucet
Repairing a leaky faucet often involves replacing worn parts. The specific process depends on the type of faucet you have. Common types include compression, cartridge, and ball faucets, each requiring a slightly different approach. This section details the repair process for each, focusing on replacing worn washers and cartridges, and providing guidance on lubrication and reassembly to prevent future leaks.
Replacing a Worn Faucet Washer
Replacing a worn washer is a common repair for compression faucets. These faucets use separate hot and cold handles, each controlling a separate valve. A washer, located at the end of the valve stem, seals the water flow. Over time, these washers wear down, leading to leaks.
- Turn off the water supply: Locate the shut-off valves under the sink for both hot and cold water lines. Turn them clockwise to stop the water flow.
- Remove the handle: Most handles are secured by a setscrew. Use a small screwdriver to loosen and remove this screw. Carefully remove the handle.
- Remove the packing nut: This nut is located beneath the handle. Unscrew it counterclockwise using an appropriate wrench. Be careful not to damage the valve stem.
- Remove the stem: Once the packing nut is removed, the stem should pull out relatively easily. Note the orientation of any components before removal to facilitate reassembly.
- Replace the washer: The washer is located at the bottom of the stem. Carefully remove the old washer and replace it with a new one of the correct size and type.
- Reassemble the faucet: Carefully reverse the steps above, ensuring all parts are correctly aligned. Tighten the packing nut securely, but avoid over-tightening.
- Turn on the water supply: Slowly turn the water supply valves counterclockwise to check for leaks.
Imagine the washer as a small rubber disc. The old, worn washer might be cracked, deformed, or significantly thinner than a new one. Replacing it with a fresh, correctly sized washer ensures a proper seal.
Repairing Different Faucet Types
While replacing a washer is common for compression faucets, cartridge and ball faucets require different approaches.
| Faucet Type | Repair Process |
|---|---|
| Compression | Replace worn washers on individual stems. |
| Cartridge | Replace the entire cartridge assembly. |
| Ball | Replace the ball, springs, and seats within the faucet body. |
Each faucet type has its unique internal mechanism. Understanding the specific components is crucial for effective repair.
Replacing a Leaking Cartridge
Cartridge faucets use a single cartridge containing all the internal parts. Replacing a leaking cartridge is generally straightforward.
