Main Causes of a Leaking Bathroom Faucet
Leaks can appear from several different components. The most common issues include:
1. Worn-Out Washer
Washers are the most common cause of faucet leaks. Every time you turn your faucet on and off, the washer presses against the valve seat. Over time, this friction wears the washer down, causing a poor seal.
2. Damaged O-Ring
O-rings are small rubber seals located around the faucet’s stem screw. A damaged O-ring can cause leaks near the handle area.
3. Corroded Valve Seat
The valve seat connects the faucet to the spout. If your water supply has a high mineral content, deposits can build up here, leading to corrosion and leaks at the base of the spout.
4. Loose Parts & Mineral Build-Up
Over time, screws and nuts may loosen, and mineral deposits can accumulate, preventing a watertight seal.
5. Faulty Cartridge or Ceramic Disc
In cartridge and ceramic disc faucets, the entire cartridge or disc set may need replacement if it’s cracked, chipped, or worn out.
