How to Undo a Bathroom Mixer Tap: A Comprehensive Guide

Bathroom mixer taps are versatile and convenient, allowing users to easily control water flow and temperature. However, maintenance is essential to maintain their functionality and prevent leaks or other issues. One of the most common maintenance tasks is undoing the mixer tap to access its internal components or replace faulty parts.

Identifying the Type of Mixer Tap

Before attempting to undo a bathroom mixer tap, it is crucial to identify its type. The most common types are:

Single-lever mixers: These have one handle that controls both hot and cold water, making them easy to use.
Two-handle mixers: These have separate handles for hot and cold water, providing more precise temperature control.

Different mixer tap types may require slightly different steps for undoing, so it is essential to identify the type before proceeding.

Required Tools

To undo a bathroom mixer tap, you will need the following tools:

Allen key (hex key) of the appropriate size
Phillips head screwdriver
Adjustable wrench
Plumber's wrench (optional)

Step-by-Step Instructions

For Single-lever Mixers:

1. Turn off the water supply to the tap.

2. Loosen the grub screw located underneath the handle using the appropriate Allen key.

3. Pull the handle straight up to detach it from the tap.

4. Using the adjustable wrench, carefully loosen the nut underneath the handle. It may be necessary to hold the tap body with the other hand to prevent it from turning.

5. Lift the mixer tap body straight up to remove it.

For Two-handle Mixers:

1. Turn off the water supply to the tap.

2. Using the Phillips head screwdriver, unscrew the handle caps (usually located on the outer edge of the handles).

3. Remove the handles by pulling them straight off.

4. Using the adjustable wrench, loosen the nuts underneath the handles. As with single-lever mixers, it may be necessary to hold the tap body.

5. Lift the mixer tap body straight up to remove it.

Additional Tips

If the nuts are particularly tight, use a plumber's wrench for extra leverage. However, be careful not to overtighten them when reassembling.
If the tap is old or heavily corroded, it may be necessary to use penetrating oil to loosen the nuts and bolts.
When reassembling the tap, be sure to use Teflon tape around the threads of the nuts to create a watertight seal.

Conclusion

Undoing a bathroom mixer tap can be a straightforward task with the right tools and knowledge. By following these instructions, you can safely disassemble the tap to access its internal components or replace faulty parts. If you encounter any difficulties or have any doubts, do not hesitate to consult a professional plumber for assistance.
