How Can I Maintain My Promax Water Tank to Ensure Optimal Performance?

To ensure optimal performance of your Promax water tank, it’s important to conduct proper maintenance.
1. Inspect your tank: Inspect the tank at least once a year for signs of wear, damage, or contamination, such as cracks, leaks, or algae growth.
2. Clean your tank: Clean your tank every 2-3 years (or when needed); drain it, remove sediment and debris, and scrub the interior with a disinfectant.
3. Check and maintain fittings: Regularly inspect all fittings, pipes, and valves to prevent leaks and water contamination. Ensure you replace anyworn or damaged parts promptly.
4. Ensure proper ventilation: Keep the vent clear from blockages. Optimal ventilation prevents vacuum formation and the growth of anaerobic bacteria.
5. Clean your roof and gutters: If your tank collects rainwater, it’s vital to clean your roof and gutter system regularly. Consider installing gutter
guards to reduce debris.
6. Install a Filter: Installing a water filter at the tank inlet removes particles and improves water quality.
7. Clear overflow system: A clear and functioning overflow system prevents water from logging around the tank.
8. Winterise your tank (if necessary): In New Zealand’s coldest regions, you may need to insulate pipes and use heaters or circulation pumps to prevent the water from freezing.

What Makes Promax Tanks the Strongest in NZ?

Promax has built a strong reputation in New Zealand for providing reliable and long-lasting water tanks. Promax's Enduro range, is the only tank on the NZ market with a corrugated wall. The Enduro tanks incorporate structural features like ribbing and corrugation to enhance their ability to withstand external pressures and seismic activity. The rotational moulding process creates tanks without seams or weak points, reducing the risk of leaks or cracks over time. Thorough testing and quality
checks ensure the tanks meet high performance standards.
