54L Caravan Water Tank for Fresh or Grey Water

This 54 litre tank gives you a simple way to manage fresh water or grey water on caravan and RV trips. It suits caravans, camper trailers, and custom trailer builds that need a tough and clean storage option. The tank is blow-moulded from high-density polyethylene that stays odourless and suitable for potable water. It holds its shape in Australian conditions and does not pass on taste during long storage.

You can use it as a fresh water tank or as a caravan grey water tank because it has three moulded 20mm BSP fittings. These fittings let you add a drain, link more tanks, or set up an overflow based on the layout of your model. It mounts well in many caravan and RV applications and fits common tray and headboard installations. The light build makes it easy to handle, clean, and fit with standard water tank accessories.

Why It Works Well in Australian Conditions

The polyethylene body handles heat, dust, and rough roads common across Australia. It resists corrosion and holds its seal when mounted under a floor or inside a trailer. The simple design makes it a good option for local camper trailer manufacturers and DIY builds. The fittings also make it easy to add a drain, overflow, or line to a 12V water system.

Frequently Asked Questions

Do the tanks need cleaning before first use?

Yes. Rinse the inside with clean water before filling.

Can I run a 12V pump from this tank?

Yes. You can connect a 12V pump to one of the 20mm BSP outlets. A small filter or strainer helps protect the pump and fittings from fine debris.

Can I link two tanks together for more storage?

Yes. The 20mm BSP fittings make it easy to link two tanks. You can use a balance line to keep the water level even between both units. If you need a ready-made dual setup, you can view the matched pair kit here: Outback Explorer 54L Water Tank Pair
