How To Fix a Leaking Tap Bonnet

A tap bonnet covers, secures and protects the valve inside the faucet. It screws onto the body of the tap, helping to prevent leaks by keeping everything sealed and contained. The tap bonnet can be removed, allowing maintenance or repair work access.

Good news – taps can be easily repaired. Simply turn off the water at the mains, open the handle to a complete ‘on’ position and remove the tap handle. Unscrew and remove the flange, bonnet and spindle. This can be the tricky part as they can be stuck to the benchtop with grease and grime. If unsure, visit our plumbing directory and consult a professional plumber. Don’t use plyers to remove the flange as this will likely damage the finish of your taps. You can easily replace the o-ring and fibre body washer when disassembling the tap. At this point, it’s also a good idea to replace the tap valve. Reassemble, turn the water on at the mains and check for leaks.
