Steps to Install a Water Butt Diverter Kit:
- Choose the Right Spot
- Place your water butt on a flat, stable base close to a downpipe.
- Make sure it’s elevated slightly for tap access and to allow room for a watering can. If applicable add a water butt stand.
- Mark the Hole on the Water Butt
- Use the diverter kit instructions to measure and mark where to drill the inlet hole on the side of the water butt (usually 8–10 cm below the top).
- Drill the Hole in the Water Butt
- Using the correct size hole saw or drill bit, carefully drill a hole at the marked spot.
- Insert the rubber grommet or fitting that came with your kit.
- Cut and Fit the Diverter into the Downpipe
- Measure and mark the correct position on your downpipe (generally level with or just above the hole in the water butt).
- Use a hacksaw to cut out the section of pipe if needed.
- Fit the diverter into the downpipe according to the manufacturer’s instructions.
- Connect the Diverter Hose
- Attach the hose from the diverter to the fitting on the water butt.
- Ensure it’s a tight fit and at the correct height so water flows properly.
- Secure and Test the System
- Make sure everything is watertight and the connections are firm.
- Pour water into the top of the downpipe or wait for rainfall to test the system.
- Install an Overflow or Stop Valve (Optional)
- Some kits include an overflow return or valve to stop overfilling. Fit this if included.
