Plastic Water Butt Tap
This is a plastic water butt tap with a ¾ inch thread. It has a washer and back nut to affix it securely to your waterbutt. To attach, first drill a 25 mm hole through your plastic waterbutt, then push the tap through, with the washer outside the tank, and screw the backnut to the back of the tap to hold the tap firmly in place.
The tap has a larger, quicker flow end to allow a smooth flow.
