INSTRUCTIONS FOR KNOCKING THROUGH THE TAP HOLE
You will need:
A 10mm Pin or Centre Punch
A Claw Hammer
Safety Goggles & Gloves
It is highly recommended that safety goggles and gloves are worn when knocking through the tap hole.
Position the pin punch on the surface of the sink over the centre of the part-drilled hole (please note that the red dot labels are for guidance only and do not give the exact centre of the tap hole).
Gently tap the punch with a claw hammer until a hole is punched through, and then continue tapping out the excess from around the hole, ensuring any rough or sharp edges are removed.
