People are asking

Can the 40L water tank be used for fresh or grey water?

Yes. The 40L plastic tank is suitable for both fresh and grey water use. If used for drinking water, ensure the tank material is food-grade and rinse thoroughly before first use. Label tanks clearly to avoid cross-contamination between fresh and grey water.

Does the 40L tank meet NZ self-containment requirements?

A 40L tank exceeds the minimum 25L fresh and grey water capacity required for two-person NZ self-containment certification under NZS 5465:2001. Its larger size is useful for extended off-grid trips or builds certified for more than two people.

How do I vent a water tank in a campervan?

Water tanks need a vent to allow air in as water is drawn out, preventing vacuum collapse. For fresh water tanks, a small vent fitting or non-return valve is installed at the top of the tank. Grey water tanks vent to the outside via a rooftop mushroom vent such as the Seaflo plumbing vent available at Vanlifer.
