IMPORTANT
The following is important to prevent stress on the tank and fittings, and to allow for normal expansion/shrinkage in all weather conditions:

  • Use high quality HDPE plastic pipe and fittings (not iron or metal) that allow for flexibility between the tank and main water supply line.
  • Connections should always be supported.
  • When linking tanks in series please note that it must never be done by connecting them with a straight pipe between the tanks. It is always advised to use elbows/t-pieces to connect to a pipe that is parallel to the tanks and feeds to your mains or pressure pump.

TANK INSTALLATION GUIDELINES

When preparing the foundation for your tank/s, take note of the following:

  • Tanks must be installed on a sound, level and smooth surface. Level paving will suffice, or a properly designed tank stand. Alternatively a concrete plinth needs to be built, ideally with a concrete surface bed of at least 85mm thick and 100mm wider than the base of the tank.
  • There should be no overhang if the tank is placed onto the base/foundation.
  • Should a tank stand be used, supporting beams should not be more than 5 cm apart

BEST PRACTISE GUIDELINES

A few basic best practices to take note of:

  • The filling rate should never exceed the overflow rate.
  • It is recommended to use ball valves to isolate the supply when needed to each tank, as well as your main water supply line.
  • For small scale domestic installations 25mm connections will suffice, but we advise using 32mm for larger systems.
