1. Turn off the water supply to the tap.
2. Using a 2mm or 2.5 mm Allen key, loosen and remove the grub screw located at the rear of the tap body that secures the spout. Alternatively, if your tap has a locking nut at the base of the spout, simply turn the locking nut anti-clockwise to loosen it.
3. Carefully lift the spout straight upwards. If the spout has not been removed for some time, it may be tight due to limescale or worn seals. Gently twist the spout while pulling upwards until it comes free.
4. Clean the inside of the tap body to remove any dirt, debris, or limescale.
5. Lightly lubricate the new O-rings with a silicone-based plumber's grease. Do not use petroleum-based grease like vaseline, as this can damage the rubber seals.
6. Carefully insert the spout back into the tap body, ensuring it is fully seated and rotates smoothly.
7. Refit and tighten the grub screw to secure the spout. Do not overtighten, as this may damage the screw or restrict the movement of the spout.
8. Turn the water supply back on and check for any leaks around the base of the spout. Rotate the spout several times to ensure it moves freely and the seals are seated correctly.
