Buying Guide for a 100 Gallon Plastic Tank

Understanding Your Needs

When I first considered purchasing a 100 gallon plastic tank, I started by assessing exactly what I needed it for. Are you storing water, chemicals, or other liquids? Knowing the purpose helps determine the type of plastic and features required. I found that some tanks are better suited for potable water, while others are designed to handle harsh chemicals safely.

Material and Durability

I paid close attention to the material of the tank. Most 100 gallon plastic tanks are made from polyethylene, which offers great durability and resistance to impact. I made sure the tank was UV-stabilized if I planned to keep it outdoors, as this protects it from sun damage and prolongs its lifespan.

Size and Dimensions

Although the capacity is fixed at 100 gallons, I checked the tank’s dimensions to ensure it would fit in my intended space. Consider the footprint and height, especially if you have limited room or need to transport the tank. I also thought about how easy it would be to maneuver once filled.

Shape and Design

I noticed that tanks come in various shapes—cylindrical, rectangular, or square. The shape affects how it fits into your space and how stable it is. Rectangular tanks often make better use of space and are easier to stack or store against walls, something I found useful in my setup.

Fittings and Accessories

I looked for tanks with compatible fittings and inlet/outlet options that suited my plumbing needs. Some tanks come with threaded openings or built-in valves, which can save time and money. If not included, I planned for additional parts to connect hoses or pumps properly.

Portability and Handling

Considering the tank’s weight when empty and full was important to me. Some plastic tanks have handles or molded grips, which made moving them easier. If I needed to transport or relocate the tank frequently, this feature was a big plus.

Maintenance and Cleaning

I also thought about how easy it would be to clean and maintain the tank. Wide openings or removable lids allowed me to access the interior for thorough cleaning. This is especially important if you’re storing water for consumption or substances that require regular sanitation.

Price and Warranty

Finally, I balanced cost with quality. While staying within my budget, I looked for tanks that offered good warranty coverage. A warranty gives peace of mind about the tank’s durability and the manufacturer’s confidence in their product.

Final Thoughts

Buying a 100 gallon plastic tank was a straightforward process once I understood my specific needs and the tank’s features. Taking the time to evaluate material, size, fittings, and maintenance helped me choose a tank that fit my requirements perfectly. I recommend anyone in the market do the same to ensure they get the best tank for their purpose.
