My Buying Guides on Water Tank 20 Gallon
When I decided to purchase a 20-gallon water tank, I realized there were several important factors to consider to ensure I got the best one for my needs. Here’s a guide based on my experience that might help you make an informed decision.
1. Purpose and Usage
First, I thought about why I needed the tank. Was it for storing drinking water, irrigation, or emergency supply? Knowing the purpose helped me narrow down features like material safety, portability, and durability.
2. Material of the Tank
Water tanks come in various materials such as plastic, stainless steel, and fiberglass. I preferred food-grade polyethylene plastic because it’s lightweight, affordable, and safe for potable water. Stainless steel is more durable but heavier and pricier, which might be better for long-term outdoor use.
3. Shape and Design
I looked at different shapes – cylindrical, rectangular, and square. Cylindrical tanks are generally more durable under pressure, while rectangular ones save space. Since I had limited space, I chose a rectangular 20-gallon tank that fit perfectly in my storage area.
4. Portability and Weight
Since I needed to move the tank occasionally, I checked the empty weight and if it had handles or fittings that made carrying easier. Some tanks come with built-in handles, which made my life much easier when transporting.
5. Inlet and Outlet Features
I made sure the tank had convenient inlet and outlet ports for filling and dispensing water. Some tanks include valves or spigots, which are handy. I opted for one with a threaded outlet so I could attach a hose easily.
6. UV Resistance and Weather Durability
Because I planned to keep my tank outdoors, I checked if it was UV resistant and could withstand weather conditions without degrading. Tanks with UV protection lasted longer and kept the water quality intact.
7. Cleaning and Maintenance
I preferred a tank that was easy to clean. A wide mouth or removable lid helps with regular maintenance, preventing algae or bacteria build-up.
8. Price and Warranty
Finally, I compared prices and looked for tanks with a warranty. It gave me peace of mind knowing the manufacturer stood behind their product.
Final Thoughts
Buying a 20-gallon water tank was straightforward once I knew what features mattered most to me. Assess your needs carefully, and you’ll find the perfect tank that fits your lifestyle and budget.
