My Buying Guides on 100 Gallon Fresh Water Tank
When I decided to purchase a 100 gallon fresh water tank, I quickly realized there were several important factors to consider to ensure I got the best value and functionality for my needs. Here’s a breakdown of what I focused on during my search:
1. Material and Durability
The first thing I looked at was the material of the tank. Most fresh water tanks are made from polyethylene, which is durable, lightweight, and resistant to corrosion. I made sure the tank was made from food-grade, BPA-free plastic to keep my water safe and fresh. Sturdiness was important to me because I wanted something that could withstand movement and temperature changes without cracking or leaking.
2. Size and Dimensions
Although the capacity was fixed at 100 gallons, I checked the tank’s dimensions carefully to make sure it would fit well in the space I had available, whether that was under a camper or in a storage area. I measured my available space beforehand and compared it to the tank specs to avoid any surprises during installation.
3. Shape and Design
I found that tanks come in a variety of shapes—rectangular, cylindrical, or low-profile. I chose a low-profile tank because it fit better under my RV and helped with weight distribution. The design also impacted how easy it was to install and connect with hoses or pumps.
4. Inlet and Outlet Placement
I paid close attention to where the inlet, outlet, and vent ports were located. Having multiple access points made it easier for me to fill, drain, and clean the tank. I also looked for tanks with threaded fittings compatible with my existing plumbing setup to minimize additional adapters.
5. Ease of Installation
Since I planned to install the tank myself, I wanted a model that was user-friendly. Some tanks come with mounting brackets or pre-drilled holes, which made the process smoother. I also checked if the tank included clear installation instructions or if I needed to source extra parts.
6. Maintenance and Cleaning
I knew that keeping the tank clean was critical to maintain water quality. I looked for tanks with wide openings or removable lids so I could easily access the interior for cleaning. Smooth interior surfaces also help prevent algae buildup, which I wanted to avoid.
7. Price and Warranty
Price was a factor, but I balanced cost against quality and features. I found that paying a bit more for a reputable brand with a warranty gave me peace of mind. A good warranty meant the manufacturer stood behind their product, which was important for something I rely on daily.
8. Reviews and Recommendations
Finally, I read plenty of customer reviews and sought recommendations from fellow RV owners and online forums. Real-world feedback helped me identify any common issues or standout features that I might not have considered.
