Why Invest in a Grey Water Tank for Your Caravan?

Grey water is the waste from showers, sinks, washing machines and other equipment. It is different from black water, which is the discharge from toilet systems. By fitting a grey water tank to your caravan, you can collect the used water to discharge it at a later stage at a suitable facility instead of discharging it at the camping ground you are parked at.


Certain states in Australia make the installation of grey water tank mandatory. Even if it’s not mandatory in your state, a caravan grey water tank can help you contribute to the environment in your own way.


You can certainly do things manually but a grey water tank makes things more convenient. What’s more? this universal tank can be used for fresh water too.

Fitting Your Caravan Water Tank

You can install grey water tank in a variety of configurations. Simply choose the configuration that offers the optimal installation for your requirements.


Be sure to make use of Teflon tape on all fittings. Also, ensure that the fittings are not cross threaded. The tank must be fully supported by no load on fittings. The tank may swell when full so be sure to keep adequate space above the tank.


Once you have finalised your installation configuration, simply drill a 3mm hole at the top of each tank for air ventilation.
