1000 Litre Rainwater Tank Installation

Below you will find the instructions you need to install the 1000 litre rainwater tank.

We have included in this guide the instructions for the freestanding as well as the wall mounted water tanks. For those that need a more practical solution we have also provided a PDF download at the bottom of this page.

It is important for all Thintanks™ being the 1000 litre, 2000 litre and 3000 litre water tanks to stand on a solid base, that will not settle or move when wet.

The water tanks can be laid on sloping ground, along the length of the tank. Surface must be horizontal (LEVEL) across the width of the tank to allow the sides of the tank to be vertical.
