A tap usually leaks around its handle because a spindle O-ring, internal seal or mixer cartridge has worn, shifted or failed. The correct repair depends on the tap mechanism and whether the body, spindle or cartridge is still serviceable.
Identify where the water starts
Dry the tap and nearby surface, then observe where water first appears while the tap is used normally. Do not remove covers or dismantle the tap.
- Multi-turn tap: Water around the handle often points to a worn spindle O-ring or seal.
- Single-lever or quarter-turn tap: A handle-area leak may indicate a failed cartridge or cartridge seal.
- Tap base: Water appearing where the tap meets the sink or benchtop can involve a different seal or a connection below. Follow the checks for a leak from the tap base.
- Spout only: A drip from the outlet usually indicates an internal sealing fault rather than a handle-area leak.
If the handle itself is loose, stiff or stripped without water escaping around it, see what a faulty tap handle can indicate. The broader guide to common tap and mixer leaks can help distinguish other locations.
Limit the leak safely
Close a working, accessible local isolation valve if one is fitted and you can operate it without force. Open the tap briefly to confirm the flow has stopped, then keep the area dry and protect the cabinet or flooring from residual water.
Do not dismantle a pressurised tap. If the water cannot be fully isolated, the valve is seized or inaccessible, or the leak is worsening, stop and call a licensed plumber. Isolate the property supply only if the normal valve is safely accessible and you know how to use it.
How is the handle leak repaired?
A licensed plumber identifies the tap mechanism, isolates and depressurises the supply, then replaces the correctly matched O-ring, seal, spindle or cartridge. If the tap body is corroded, cracked or incompatible with available parts, complete replacement may be more reliable.
Do not keep tightening the handle or add thread tape around it. These actions do not repair the internal seal and may damage the fitting or conceal the actual fault.
