It features a 1″ FNPT stainless steel port rated to 218 PSI, allowing a secure connection to standard pumps and plumbing. This tank is designed to handle typical well loads while minimizing vibrations and floor moisture thanks to its plastic base.
Key considerations
- Capacity suits mid-sized homes or small farms
- Steel shell provides long-term durability
- Food-safe liner supports potable water use
Amtrol WX-202D Well-X-Trol 20 Gal
The Amtrol WX-202D Well-X-Trol 20 Gal is a compact, durable option designed for residences with space considerations. It uses high-strength steel rated for up to 150 psig, delivering a reliable flow when demand spikes occur. The blue appliance-like finish helps integrate into typical home basements or utility rooms. The design emphasizes easy installation with a space-saving footprint, making it a practical choice for retrofit projects or new builds where wall or corner placement is preferred.
Key considerations
- Higher pressure tolerance than some compact tanks
- Space-efficient footprint for tight installations
- Residential-focused design and straightforward installation
ELEVZO 65 Gallon Stainless Steel Tank
This ELEVZO 65 Gallon tank uses thick 1/16″ 304 stainless steel to resist cracking and rust, supporting up to 43.8 PSI with robust welding and a maintenance-free profile. Its 1″ MNPT ports and a stainless steel 1″ FNPT check valve provide secure, leak-free connectivity to standard U.S. plumbing. The bladderless design minimizes maintenance concerns common with bladder tanks and is built for years of reliable operation, even in temperature extremes from -4°F to 122°F. It’s a strong option for larger households or farms seeking greater storage capacity without frequent cycling.
Key considerations
- Bladder-free stainless steel construction
- Wide operating temperature range
- Comprehensive port configuration for simple piping
Red Lion RL6AH 6-Gallon Horizontal Tank
The Red Lion RL6AH is a compact 6-gallon horizontal, pre-charged tank designed for well pump systems to maintain pressure when the pump is off. It uses a heavy-duty 20-gauge steel body and a 304 stainless steel water connection featuring leak-safe technology. The diaphragm and liner system balance performance with durability, and the tank ships pre-charged to 20 PSI, with final adjustments performed at the job site relative to the pressure switch setting. Its small size makes it ideal for tight spaces in basements or utility rooms.
Key considerations
- Compact footprint suitable for limited spaces
- Pre-charged and ready for installation
- NSF/ANSI/CAN 61 certified water safety
Red Lion RL4A 4.5-Gallon Inline Tank
The Red Lion RL4A inline pressure tank is a compact 4.5-gallon option designed to support well pump systems by reducing water hammer and maintaining steady pressure levels. It uses a 20-gauge steel shell and a 304 stainless water connection with leak-safe technology. The tank is pre-charged to 20 PSI for transport and requires a final setting to be matched to the system’s switch. Its inline design makes it a practical choice for small homes or retrofit projects where space and simple piping are priorities.
Key considerations
- Inline configuration for quick integration
- Pre-charged and easy to adjust
- Durable construction with reliable connections
Buying Guide
When selecting a well pump storage tank, consider capacity, materials, and compatibility with your existing system. Larger homes or farm operations benefit from bigger tanks like 40–65 gallons, which reduce cycling and stabilize pressure during high demand. Stainless steel tanks offer superior durability and corrosion resistance compared to standard steel tanks, especially in hard water environments. Bladderless models minimize maintenance related to diaphragms, but ensure the plumbing connections and port sizes match your pump and valve setup.
Key purchase considerations include:
- Capacity needs based on household size and water usage
- Pressure ratings (PSI) and compatibility with your pump
- Material choice: steel vs stainless steel; bladderless vs bladder tanks
- Port sizes and configurations (MNPT, FNPT, check valves)
- Space constraints and installation location
- Certifications and drinking water safety
Installation and maintenance perspectives vary by scenario. A larger tank can improve efficiency for rural or multi-user households, while compact tanks work well in apartments or retrofit projects with limited space. Consider whether you prefer maintenance-free stainless steel or a traditional bladder tank that may require occasional liner checks. Finally, verify that the selected model is compatible with your well pump’s flow rate, pressure switch settings, and plumbing fittings to ensure reliable performance and longevity.
