Constantly heaving the watering can over the edge of the water butt to take out the water? That can be pretty exhausting. An integrated drain tap is much more useful. Here you simply have to turn on the tap and the water will flow into your watering can all by itself. The assembly is not difficult at all, as these instructions prove.

Why is a drain tap useful?
- Easy removal of the irrigation water
- For emptying the rain barrel in winter
- Precise dosing when taking water
- The water taken from the water butt is free of leaves or algae
Where can I get an outlet tap?
Most of the time, a purchased water butt already comes with an outlet tap. With a bit of luck, all the materials and detailed installation instructions are included. Otherwise, you can buy a spout from any well-stocked garden center.
When do I attach the drain tap
It is important that you attach the outlet tap before you start with the other preparations. The assembly of the water butt should always be done first. Precise planning of the location and the connection of other helpful utensils is only possible with the complete model. In addition, the rain barrel is still movable at the beginning and can be turned to the side as desired.
How do I proceed?
- Check whether there is already a pre-punched hole for the drain tap.
- Cut out the material at this point.
- Otherwise, drill a hole in the rain barrel.
- Fix the outlet tap with screws.
- Check your construction for a firm seat and a suitable height.
At what height do I attach the outlet tap?
The drain cock is mounted in the lower area of the water butt. You should still keep a little distance to the ground. If you have placed your water butt on the pedestal, a watering can should fit under the tap without any problems.
What should I put attention on?
The outlet tap must be stable and vertical. When drilling the hole, you should ensure clean processing and seal leaks securely.
