Can my water butt be attached to a wall?

Most water butts also known as water tanks are stable structures. Any water butts that, due to their particular shape, could fall down, we supply wall mounting brackets for added stability.

How do I prepare my water butt for winter?

Water butts can freeze if not drained for the winter, depending on their location and local weather conditions. If water freezes in your receptacle, the water butt may crack or deform under the pressure.

Do the water butts need added filtration devices?

All of Garden Tech’s water harvesting products are already equipped with a filtration device. Collected rainwater should only be used for gardening purposes and should not require any extra filtration.

How do the downpipe filters work?

When collecting rainwater, a downpipe will collect water from the roof via a drainpipe connected to your water butt. The downpipe filter works by combining a steel or plastic grid with the walls of the downpipe, to allow heavier bodies to fall through the centre of the pipe.

Can multiple water tanks be joined together?

Our range of water butts can be easily joined together if needed. This can be done with a simple connection kit that contains a small hose, a drill bit, and the fittings needed to connect the water butts together.

Shouldn’t the tap be at the bottom of the water butts?

No. This clever design feature ensures that the water butt always contains enough water to maintain its stability and avoid it getting blown over by the wind.
