WOWOW FaucetsWhat Is a Faucet Valve and How Does It Work?
A faucet valve controls the flow and temperature of water inside the faucet. When you turn the handle, the valve opens, closes, or mixes hot and cold water depending on the faucet type.
Types of Faucet Valves
- Compression valve: Uses a washer that presses against a seat to stop water.
- Ball valve: Uses a rotating ball with openings to control flow and temperature.
- Cartridge valve: Uses a replaceable cartridge, common in one-handle and two-handle faucets.
- Ceramic disc valve: Uses two ceramic discs for durable, drip-free control.
Why It Matters
The valve is the part that most often needs repair when a faucet drips or becomes hard to turn. Knowing the valve type helps you buy the correct replacement part.
