Understanding the Drip
A dripping bathroom faucet, even if it’s just a slow drip, can be a frustrating and wasteful problem. It’s a sign that your faucet’s internal mechanisms are not sealing properly, leading to a constant stream of water. Understanding the common causes of dripping faucets will help you diagnose and potentially fix the issue yourself.
Faucet Types and Dripping Mechanisms
Different types of faucets have different internal mechanisms that can cause dripping. The most common types are compression faucets, ball faucets, cartridge faucets, and ceramic disc faucets.
- Compression Faucets: These older faucets use a rubber washer to seal the water flow. Over time, the washer can wear out, become brittle, or get stuck in the valve seat, leading to dripping. The washer is held in place by a stem that is tightened or loosened by a handle. A worn-out washer can cause dripping when the faucet is turned off.
- Ball Faucets: Ball faucets have a ball-shaped valve that controls water flow. The ball has grooves that align with inlets and outlets, allowing water to flow through. A rubber O-ring seals the ball against the valve seat. Dripping can occur when the O-ring wears out, gets damaged, or gets stuck in the valve seat.
- Cartridge Faucets: Cartridge faucets have a single cartridge that contains all the components necessary to control water flow. The cartridge is a cylindrical unit that houses a rubber O-ring or a ceramic disc. Dripping can occur when the O-ring or ceramic disc wears out, becomes damaged, or gets stuck in the valve seat.
- Ceramic Disc Faucets: These faucets use two ceramic discs to control water flow. The discs have precisely machined grooves that align to allow water to flow through. Dripping can occur when the discs become worn, damaged, or misaligned.
Faucet Components and Dripping Causes
Several components within a faucet can cause dripping, each requiring a specific repair approach.
- Washer: The washer is a rubber or plastic disc that seals the water flow in compression faucets. Over time, the washer can wear out, become brittle, or get stuck in the valve seat, causing dripping. Replacing the washer is a common fix for dripping compression faucets.
- O-ring: O-rings are small rubber rings that seal the water flow in ball faucets, cartridge faucets, and some other types. They can wear out, become damaged, or get stuck in the valve seat, causing dripping. Replacing the O-ring is often the solution.
- Cartridge: The cartridge is a single unit in cartridge faucets that contains the components necessary to control water flow. If the cartridge is worn out or damaged, it can cause dripping. Replacing the cartridge is typically the solution.
- Valve Seat: The valve seat is the surface against which the washer, O-ring, or ceramic disc seals. If the valve seat is worn, damaged, or corroded, it can prevent a proper seal and cause dripping. Replacing the valve seat is sometimes necessary.
