Please note that we always recommend waiting for the product to arrive prior to drilling or permanently altering your water tank. 

Installation Instructions:

1. Find the pre-drilled/fitted hole on your tank and see if our adapter is compatible, if it is not compatible then drill a new hole in your place of choice
2. Take the nut off the adapter and leave 1 washer on the thread, then insert the adapter into the hole from step 1.
3. Place the second washer on the thread inside your tank, then screw on the nut as tight as possible, you do not need to use a tool for this, hand tight with both washers should prevent leaking.
4. Screw on your tap to the newly fitted female outlet on your tank, please note that due to the internal washer, this may require some force and for the threads to be aligned correctly. We are not responsible for cross threading or user error during installation.
   Please note that not all taps on this listing are made from metal. Some taps may come with plastic fittings and connectors as shown in the photos.
