A compact five-gallon holding tank designed for secure storage in mobile and household settings. Built to resist vibration and to be installed in a range of positions.
Long-lasting durability - thanks to LLDPE construction
High-toughness linear low-density polyethylene resists vibration and stamping, and performs across a wide temperature window from -40 to 80 degrees Celsius. The polymer structure tolerates repeated movement common in trailers and boats.
Durable material minimises the chance of cracks or deformation during travel, reducing maintenance and replacement frequency.
Leakproof storage - with welding gap design and sealed cover
A welding gap design strengthens seams while a sealed cover secures the 100mm inlet, improving resistance to damage and leakage. The large screw cover creates a reliable barrier against spills.
Secure seams and a tight cover keep drinking water safe and lower the risk of messy leaks while on the move.
Faster fills and flexible placement - with 100mm inlet and adjustable installation
A 100mm diameter inlet enables quick water top-ups and accepts large hoses or funnels for rapid filling. Adjustable mounting options allow the tank to be positioned to suit different RV, trailer or boat layouts.
Quicker refills at campsite taps and adaptable installation make it easier to integrate the tank into limited or awkward spaces.
