How To Install A Water Butt

Water butts are containers for collecting rainwater, often made from molded plastic. When a water butt is fitted to a drainpipe it will collect rainwater from your roof. This water can then be used to water your garden or for washing you car, saving water and reducing your water bills if you have a water meter.

Water butts are easy to fit too! All you have to do is find a suitable location near a downpipe. The space you'll need will depend on the water butt chosen. Most water butts sit on the ground (or on a stand), but some can be fixed flat against your wall.

Fitting the water butt involves cutting a small section out of your downpipe (drainpipe) and inserting a rainwater diverter into the space. The rainwater diverter is then connected to the top side of the water butt. Some water butts will require a hole drilling in order to take the feed from the diverter. The diverter is included in the water butt kits, or it can be bought separately with a single water butt or tank.

When it rains, the water runs down the downpipe in the usual way, but the diverter will catch this and divert it into your water butt. Once the water butt is full, the water will just continue down the downpipe as it would have done without the water butt being there.

Your water butt needs to be sited on a level surface, whether or not you decide to use a stand. The stand raises the butt off the ground allowing you to fill a watering can or container much more easily. The stand is included in the water butt kits, or it can be bought separately with a single water butt or tank.

If you have more than one water butt you can link them together by using a water butt linking kit to do this.

A secure childproof lid is also very important for safety, but also stops any unwanted debris falling into your water butt. It's also useful to use Refresh liquid to keep the water in your water butt free of algae and odours.
