Choose your downpipe diverter

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.

Installation Guide

The Essential Range tanks come in three parts:

  1. The stand
  2. The water butt
  3. The lid

Upon delivery or collection, the stand, diverter, and tap are placed inside the tank for compact transport.


Assembly Steps

  1. Remove the stand from inside the tank.

  2. Place the stand on a flat, level surface (many people use a paver for stability).

  3. Position the water butt on top of the stand.

  4. Secure the lid once everything is in place.

Refer to the image below to ensure correct assembly:


Installing the Diverter

  1. The drill bit required for installation is included in the diverter pack.

  2. Drill one hole in your downpipe and one in the tank using the supplied bit.

  3. Ensure both holes are level, as shown in the image below — this is essential for the overflow to function properly.

  4. Cut the hose to length so it runs straight, not on an angle or bend.

Installing the Tap

  • The tank has a marked position for drilling the tap hole.

  • Use a 26mm hole saw or flat drill bit to create the hole.

  • Insert and tighten the tap securely.


Installation Videos

The following videos show how to install a Speedy Downpipe Diverter and connect it to one of our tanks. The process is the same across all ranges, including the Essential Range:


Once your water butt is set up on the stand and connected to the diverter, you’re good to go.

Efficient Collection with Built-In Overflow Control

Our high-efficiency downpipe diverter collects up to 90% of the rainwater that flows through your downpipe. It includes a built-in filter that traps leaves and debris before they enter your tank, keeping your water cleaner and reducing maintenance. When the tank is full, the diverter automatically redirects excess water back down the downpipe—no overflowing, no mess, and no need to manually turn it off.
