Stone 2in1 350L Rainwater Tank - Lava

To connect your tank to your guttering, you’ll need the correct diverter for your downpipe shape.

🟦 Rectangular Diverter

Use this if your downpipe has flat sides or a rectangular shape.

⚪ Round Diverter

Use this if your downpipe is fully round.

✅ Quick check: If the downpipe is round all the way around, choose the round diverter. If it has any flat sides, choose the rectangular diverter.

Installing your Designer Range tank is simple and DIY-friendly. Follow the steps below to ensure proper setup and optimal performance.

1. Prepare the Base

• Place your tank on a flat, level surface.

• We recommend using a concrete paver or similar stable base to prevent movement or tilting once full.

2. Use the Included Drill Bit

• Your downpipe diverter kit comes with a drill bit for creating connection holes.

• Use it to drill:

  • One hole in the downpipe

  • One hole in the side of the tank

3. Align the Holes

• Ensure the hole in the tank and the hole in the downpipe are level with each other.

• This is essential for the overflow function to work correctly.

• Avoid angling the hose — it should run straight between the diverter and tank.

4. Fit the Diverter

• Cut the supplied hose to the required length, keeping it straight and untwisted.

• Use the faceplate that best fits your downpipe shape (round or rectangular). The second faceplate is extra and not needed if it doesn’t match.
