The Essential Guide to Buying Your Perfect Water Storage Tank
Water storage tanks are smart investments. They keep water ready for emergencies or daily use. Choosing the right one means looking closely at several important things. This guide helps you pick the best tank for your needs.
1. Key Features to Look For
When you shop, several features make a tank better or worse. Think about what you need the tank to do.
Capacity and Size
- Volume: How much water do you need to store? Tanks come in small sizes (like 50 gallons) up to huge ones (thousands of gallons). Measure your space first!
- Footprint: Does the tank need to fit in a small shed or a large yard? Some tanks are tall and narrow; others are wide and short.
Durability and Lifespan
- Warranty: A good warranty shows the maker trusts their product. Look for warranties lasting 10 years or more.
- Fittings and Openings: Check the quality of the inlet (where water goes in) and outlet (where water comes out). Strong, leak-proof fittings are crucial.
Safety and Certification
- NSF Certification: If you plan to drink this water, the tank must be certified by organizations like NSF International. This means the material will not add harmful chemicals to your drinking water.
2. Important Materials Used in Tanks
The material the tank is made from affects its cost, strength, and safety.
Polyethylene (Plastic)
This is the most common choice. It is lightweight and resists rust. High-density polyethylene (HDPE) is strong. Plastic tanks are usually the most affordable option. Be sure the plastic is “food-grade” if you plan to drink the water.
Fiberglass
Fiberglass tanks last a very long time. They handle temperature changes well. They cost more than plastic tanks upfront, but they offer excellent long-term value.
Metal (Steel or Stainless Steel)
Steel tanks are extremely strong. They are often used for very large volumes or underground storage. Stainless steel does not rust, making it excellent for drinking water, but it is the most expensive material.
3. Factors That Improve or Reduce Quality
Not all tanks are built equally. Small details change how long your tank lasts.
Quality Boosters
- UV Protection: For outdoor tanks, the material must have UV stabilizers. This stops sunlight from making the plastic weak and brittle over time.
- Wall Thickness: Thicker walls mean the tank can hold more pressure and resist damage better.
- Opaque Color: Darker or opaque colors (like black or dark green) stop sunlight from reaching the water inside. This prevents algae growth.
Quality Reducers
- Thin Walls: Cheaply made tanks often use thin walls. These can bulge or crack under the weight of the water.
- Unknown Plastics: If a tank is not clearly marked as food-grade or potable water safe, do not use it for drinking water.
4. User Experience and Use Cases
How you plan to use the tank changes what features matter most to you.
Emergency Preparedness
For emergencies, you want a simple, reliable tank. Many homeowners choose smaller, easily accessible tanks placed indoors or in a garage. Easy access to the spigot is very important here.
Rainwater Harvesting
If you collect rainwater for gardens or toilets, you need a larger capacity tank and good filtration systems connected to the top. Tanks used outdoors must have secure lids to keep out debris and pests.
Off-Grid Living
People living off-grid often need the largest tanks possible. They need tanks strong enough to handle being buried (if space is limited) or tanks that can be easily connected to pumps and pressure systems.
Frequently Asked Questions (FAQ) About Water Storage Tanks
Q: Can I store drinking water in any plastic tank?
A: No. You must use tanks specifically labeled as “food-grade” or “potable water safe.” Only these tanks use materials that will not leach harmful chemicals into your drinking supply.
Q: How often should I clean my water storage tank?
A: For drinking water, experts recommend completely draining and cleaning your tank at least once every one to two years. If you notice any bad smell or discoloration, clean it sooner.
Q: Do I need a permit to install a large water tank?
A: This depends on where you live. Local city or county rules often have limits on the size and placement of outdoor water storage. Always check with your local building department before installing a very large tank.
Q: What is the best color for an outdoor water tank?
A: Opaque colors like black, dark green, or dark blue are best. These colors block sunlight effectively, which stops algae and bacteria from growing inside the stored water.
Q: Can I bury a water storage tank?
A: Only tanks specifically designed and built for underground use should be buried. Underground tanks require extremely thick walls to resist the pressure of the surrounding soil.
Q: Will freezing temperatures damage my tank?
A: Yes, freezing water expands and can crack most plastic and fiberglass tanks. If you live in a cold climate, you must place the tank indoors, in a heated basement, or insulate and heat the tank heavily.
Q: What is the difference between a cistern and a water tank?
A: The terms are often used interchangeably, but generally, a cistern refers to a tank used to collect and store rainwater. A water tank usually refers to a container holding water from a municipal supply or well.
Q: How do I prevent mosquitoes from breeding in my tank?
A: Ensure the tank has a tight-fitting, secure lid. All openings, like inlets and overflows, must have fine mesh screening (like window screening) installed over them to block insects.
Q: Are metal tanks better than plastic tanks?
A: Metal tanks are often stronger and last longer, especially stainless steel. However, regular steel can rust if the protective lining breaks. Plastic tanks are cheaper, lighter, and naturally resist corrosion.
Q: What pressure rating do I need for my tank fittings?
A: For standard home use, fittings rated for 50 to 80 PSI (Pounds per Square Inch) are usually sufficient. Always match the fitting rating to the pressure coming from your pump or main line.
