Installation of Water Tanks:

  • Water Tanks should NOT be installed on:

(i) Rocky and Uneven Surfaces

(ii) Block and Metal Frames.

    • Best installation practice is to place your tank on a flat, smooth and even surface.
    • Outlet should be well supported to avoid the risk of leakage and damage to the water tank at outlet.

NOTE:  These Water Tanks are not designed to be installed as underground Water Tanks.

 For aboveground Water Tanks to be installed as underground, the following instructions should be followed:

  • All aboveground water tanks must be installed on a flat concrete base and protected by a retaining wall (up to the height of the water level) to avoid any lateral external pressure.
  • No external load should be applied to the water tanks.
  • Inlet and outlet pipes should be adequately supported to avoid strain on the water tanks.

Tank Plumbing

Your tank should be installed by a qualified plumber in accordance with regulations, ensuring piping and fittings are correctly done to avoid any non compliance to installation guidelines.

Water Level Indicator

Our water level indicator facilitates the monitoring of water level without hassle.

Duraco Water Level Indicator

  • Quick and easy to install, seals directly to the tank – DIY product
  • Maintenance free – no batteries or wiring required
  • Suitable for existing and new tanks up to 3.0 metres high
  • Easy to read dial face with ‘Empty’ and ‘Full’ indicators

Installation Guideline

Before installing your level indicator, it is important to calibrate it for use (adjust the indicator as per tank height).


  1. Carefully remove the front clear face from the level indicator to enable access to the moveable Empty and Full indicators.
  2. Select an installation site on your tank for the level indicator and mark it. It is preferable that it is a flat area and that once installed, will allow you to view the water level indicator face easily.
  3. Whilst maintaining the same height and keeping the weight outside of the tank, extend the weight so it is level with the bottom of your tank. Move the red Empty indicator to where the water level indicator is pointing.
  4. Lift the weight so it is level with the overflow on your tank and move the green Full indicator to where the water level indicator is pointing.
  5. Water level indicator is now calibrated. Replace the front clear face.


  1. Drill a 32mm hole into your tank at the previously marked installation site.
  2. Lower the weight through this hole and sit the level indicator on your tank.
  3. Using the supplied screws secure the level indicator to your tank.
  4. Your water level indicator is now installed and ready for use.

Depending on the quality of your water source, a Water Tank should be cleaned on a regular basis. External debris can either float on the top of the Water Tank or form sediment (mud and dirt) at the bottom of the Water Tank. It is recommended to clean your Water Tank twice a year.
