My Buying Guides on 75 Gallon Water Tank
When I decided to purchase a 75 gallon water tank, I quickly realized there are several important factors to consider to ensure I got the best product for my needs. Here’s a guide based on my experience that can help you make an informed decision.
1. Understand Your Water Storage Needs
Before diving into the specifics, I asked myself how I planned to use the tank. Was it for rainwater harvesting, emergency water storage, or agricultural use? Knowing my exact requirements helped me determine the size and type of tank that would work best.
2. Material Matters: Plastic, Steel, or Fiberglass?
I found that 75 gallon water tanks come in different materials, each with its pros and cons:
- Plastic (Polyethylene): Lightweight, affordable, and resistant to rust. Ideal for most household uses.
- Steel: Very durable and good for long-term outdoor use, but heavier and prone to rust if not properly coated.
- Fiberglass: Strong and corrosion-resistant, but tends to be more expensive.
For my needs, a high-density polyethylene tank offered the best balance of durability and price.
3. Check the Dimensions and Space Availability
Even though the tank holds 75 gallons, its physical size can vary. I measured the space where I intended to place the tank to make sure it would fit comfortably, considering both height and footprint.
4. Consider the Tank Shape and Installation Options
I noticed tanks come in vertical (cylindrical) and horizontal shapes. Vertical tanks take up less floor space but require more height clearance. Horizontal tanks are easier to fit under decks or inside sheds. Installation can be as simple as placing the tank on a flat surface or may require a stand or mounting hardware.
5. Look for Features Like Inlets, Outlets, and Fittings**
It was important for me to check what kind of inlet and outlet sizes the tank had, and whether it included fittings or if I needed to purchase them separately. Some tanks come with threaded openings, spigots, or valve attachments that make connecting hoses or pumps easier.
6. Consider Portability and Weight When Full
Since water weighs about 8.34 pounds per gallon, a 75 gallon tank full of water weighs over 625 pounds. I made sure the tank was sturdy and stable enough to handle the weight, and if I needed to move it, I looked for models with handles or compatible carts.
7. Evaluate UV Resistance and Durability for Outdoor Use
Because I planned to keep my tank outside, I checked if it was UV resistant to prevent cracking or degradation from sun exposure. Tanks with UV inhibitors in their plastic lasted longer and maintained their color and strength.
8. Price vs. Quality Balance
I compared prices from different brands and sellers, but I didn’t just go for the cheapest option. I balanced cost with reviews, warranty, and material quality to ensure I was getting value for my money.
9. Maintenance and Cleaning Ease
A tank with a wide opening made it easier for me to clean and inspect. Some models also come with accessories like lids or screens to keep debris and insects out.
10. Reviews and Brand Reputation
Finally, I read customer reviews and chose brands known for reliability. Real user experiences highlighted potential issues or benefits that specs alone don’t reveal.

By keeping these points in mind, I was able to select a 75 gallon water tank that perfectly suited my needs and gave me peace of mind knowing I made a smart purchase. I hope my guide helps you find the right tank for your situation too!
