🏡 General Buying Questions
Q: What size water storage tank do I need for my home?
A: It depends on your household size and water usage. A family of four typically uses a 500–1,500 gallon tank for emergency or off-grid use. For daily use, you may need a larger capacity depending on water demand.
Q: What is the best water tank for home use?
A: High-density polyethylene (HDPE) tanks that are FDA-approved and UV-stabilized are ideal for drinking water. They’re durable, non-corrosive, and safe for long-term water storage.
Q: Where can I buy a drinking water storage tank?
A: You can purchase water tanks from All About Tanks online stores like ours that offer a range of sizes, fittings, and colors for residential use.
💧 Material & Safety
Q: Are plastic water tanks safe for drinking water?
A: Yes — as long as the tank is made from food-grade and meets FDA standards for potable water storage.
Q: What color tank is best to reduce algae growth?
A: Black and dark green tanks block sunlight better than lighter colors, helping to prevent algae buildup in your stored water.
Q: What certifications should I look for in a potable water tank?
A: FDA-approved for storing drinking water.
🔧 Installation & Maintenance
Q: Can I install a water storage tank myself?
A: Yes — many tanks are designed for simple DIY installation. Just ensure you place it on a solid, sharp object free foundation and level base.
Q: Can I bury my water storage tank underground?
A: All About Tanks recommends a Cistern that is designed for underground use. Standard above-ground tanks are not built to handle external soil pressure.
Q: How often should I clean my water tank?
A: Clean and sanitize your tank at least once a year to ensure water quality. Use a diluted bleach solution or approved sanitizers.
Q: What kind of base do I need for my tank?
A: Use a level, compacted gravel or concrete pad to support your tank and prevent shifting or cracking.
Q: Are customized outlets available for home drinking water storage tanks?
A: Yes, consult with your contact at All About Tanks discuss your needs.
🧮 Capacity & Usage
Q: How long will a 500-gallon tank last for a family of four?
A: On average, it can supply drinking, cooking, and basic hygiene water for 2–3 weeks, depending on usage.
Q: What’s the difference between vertical and horizontal/rectangular water tanks?
A: Vertical tanks are better for stationary use and take up less ground space. Horizontal tanks are ideal for transport or areas with height restrictions.
Q: How much water should I store for emergencies?
A: FEMA recommends at least 1 gallon of water per person per day for 14 days — so a family of four should store at least 56 gallons for short-term use.
⚠️ Regulations & Off-Grid Use
Q: Do I need a permit to install a water storage tank?
A: Some municipalities require permits, especially for large tanks or plumbing connections. Check with your local building authority.
Q: Can I connect a tank to my home's plumbing or well system?
A: Yes — many homeowners use booster pumps, float valves, and filtration to integrate tanks into household plumbing, especially in off-grid or backup scenarios.
Q: Is a water tank a good idea for off-grid living?
A: Absolutely. Water tanks are essential for collecting, storing, and using rainwater or delivered potable water in off-grid systems.
Q: How long can water be safely stored in a tank?
A: With clean water, a sanitized tank, and minimal sunlight exposure, stored water can remain potable for 6–12 months or longer. Rotating your supply is always recommended.
