How to repair leaking mixer taps?

mickkuffer

Trying to repair these taps first 2 pics are of shower & last 2 pics are of basin sink, as both are dripping.

How do I remove taps to replace washers/ seals?

Is there a grub screw hidden beneath the visible plug/ bulge on underside of handle?

What type of washer/ seals do they use?

Are they generic?

Do I need specialty tools?

Thanking you in advance for assistance.

Hi @mickkuffer,

Welcome to the Bunnings Workshop community.

Please note that plumbing work needs to be completed by a licensed professional for safety and compliance.

These are mixer taps rather than traditional taps with separate washers. They typically use an internal cartridge rather than standard tap washers or seals.

There is usually a small grub screw hidden behind a plug on the handle, which allows the handle to be removed to reveal the mixer cartridge.

Unfortunately, replacing a mixer cartridge is generally considered licensed plumbing work in most jurisdictions. For safety and compliance reasons, I’d recommend engaging a licensed plumber to inspect both mixers and replace the cartridges if required. They’ll be able to identify the correct replacement cartridge, as these are not always generic and often need to match the specific tap brand and model.

Sorry I can’t provide step-by-step instructions on this one, but a plumber should be able to sort both dripping taps for you.
