FAQs

Provide proper air holes in the tank during installation to ensure adequate ventilation and maintain consistent water pressure inside the tank.

Keep the tank lid tightly closed at all times to maintain water cleanliness and hygiene. An open lid exposes water to dust, insects and harmful UV rays that can damage the tank's inner layers.

Always use a proper drilling machine to make inlet and outlet holes for pipe fitting connections. Never use a chisel or sharp tools — this can crack or damage the tank permanently.

To utilize the full storage capacity of your tank, always fit the overflow pipe above the level of the inlet pipe — this ensures maximum water usage without wastage.

Do not store chemicals or non-potable liquids in food-grade water tanks. Allwin tanks are designed specifically for clean drinking water storage.

Clean the inside of the tank at least once every 6 months to maintain water purity and extend the life of your tank.

Periodically inspect all inlet, outlet and overflow fittings for leaks or looseness and tighten them as needed.
