- Disassemble the Tap: Use a wrench to unscrew the tap handle and access the washer.
- Replace the Washer: Take out the old washer and replace it with a new one.

2. Loose O-Ring
Why It Happens:
The O-ring is a small rubber ring that sits inside the tap handle. It can become loose or damaged, leading to leaks around the handle.
How to Fix It:
- Turn Off the Water: Make sure the water supply is off.
- Remove the Handle: Unscrew the tap handle to access the O-ring.
- Replace the O-Ring: Take out the old O-ring and replace it with a new one.

3. Corroded Valve Seat
Why It Happens:
The valve seat connects the tap to the spout. Over time, it can corrode and cause leaks at the spout’s base.

A cartridge controls the water flow and temperature. If it’s faulty, it can cause leaks from the spout or base.
How to Fix It:
