Horizontal Leg Tanks are for storage and are not to be pressurized.
 
This 35G horizontal tank delivers exceptional versatility through its horizontal leg configuration, making it ideal for environments where space comes at a premium. Unlike bulkier vertical water storage tanks that demand significant overhead clearance, this compact unit stands just 21.5 inches tall while stretching 33 inches in length. This low-profile footprint allows installation beneath workbenches, alongside walls, or within cabinets where taller alternatives simply won't accommodate. The integrated leg supports distribute weight evenly across the base, eliminating the need for additional platform construction or reinforcement that many storage solutions require.
 
Homeowners appreciate the flexibility this 35G water storage tank provides for utility closets, garage corners, and basement installations where ceiling height restrictions often limit options. The tan exterior finish offers more than aesthetics—it reflects solar radiation more effectively than darker alternatives, helping maintain cooler internal temperatures during warm weather. This thermal advantage proves particularly valuable for potable water applications or chemical storage, where temperature stability enhances product longevity and safety.
 
Lightweight Construction Meets Heavy-Duty Performance
 
At only 17 pounds empty, this 35g poly tank for water storage can be easily repositioned by a single person, yet the rotationally molded polyethylene construction handles demanding conditions with impressive durability. The 1.2 specific gravity rating confirms this tank's capability to store denser liquids beyond just water, including agricultural solutions, RV waste holding, and various industrial fluids. Maximum temperature tolerance reaches 140°F, accommodating warm liquid storage scenarios that would compromise lesser containers.
 
The 8-inch threaded lid provides generous access for filling, cleaning, and maintenance tasks. This opening diameter accommodates standard pumps and fixtures, while the secure threading prevents accidental spills or contamination. UV inhibitors integrated throughout the polyethylene material protect stored contents from direct sunlight exposure, extending the useful life of sensitive liquids and preventing degradation that shortens storage duration.

Frequently Asking Questions
 
Can this 35g water tank withstand freezing temperatures?
The polyethylene material remains flexible in cold conditions, but we recommend draining the tank before sustained freezing weather. While the tank itself resists cold damage, expanding ice can create internal pressure that stresses seams and fittings. For winter outdoor storage, wrap the tank with insulation or relocate to heated spaces.
 
How should I secure this 35g tank for water storage during vehicle transport?
Always transport empty and use quality ratchet straps anchored through the leg supports. The lightweight construction makes movement easy, but sloshing liquid creates dangerous weight distribution issues. Secure the tank in multiple directions to prevent sliding or tipping during acceleration, braking, and cornering.
 
Does the tan color impact stored water temperature?
Yes significantly. Tan reflects more sunlight than black or green options, keeping contents noticeably cooler in direct sun. This makes the tan finish preferable for drinking water or temperature-sensitive storage applications. All colors include identical UV protection for liquid preservation.
 
Can I connect this to a well pump pressure system?
Never pressurize this storage tank. It's designed exclusively for unpressurized, gravity-fed applications. Attempting to pressurize this 35g poly tank for water storage will void the warranty and create serious rupture risks. For pressurized systems, only use tanks specifically rated for pressure applications.
