Red Lion RL20A 20-Gallon Pressure Tank
The Red Lion RL20A is a 20-gallon vertical pre-charged pressure tank designed to maintain water pressure when the well pump stops. It is NSF/ANSI/CAN 61 and 372 approved for safe, drinking water, aligning with standard American household requirements. The heavy-duty 20-gauge steel tank pairs with a 304 stainless steel water connection featuring leak-safe technology and a high-performance butyl rubber diaphragm with a propylene liner. Setup is straightforward: the tank ships pre-charged to 20 PSI, and field adjustment should bring the air pressure to two PSI below the system’s cut-in setting using a bicycle pump. This model is suitable for larger homes or systems with higher water demand, and it provides reliable pressure consistency across cycles.
Key features include durable construction, certified water safety, and a diaphragm design that minimizes leakage risk. The RL20A’s 1-inch FNPT elbow connection supports robust installation; the almond finish blends with many plumbing setups. As with all such tanks, regular checks of tank air pressure and diaphragm integrity help sustain peak performance and extend service life. This unit is an excellent option for households seeking a larger-capacity solution that reduces cycling without compromising water quality.
Red Lion RL2A 2-Gallon Inline Tank
Designed to work with well pump systems to maintain pressure and reduce water hammer, the Red Lion RL2A is a compact inline pre-charged tank. Its 20-gauge steel construction and 304 stainless steel water connection with leak-safe technology deliver dependable durability in tight spaces. With a pre-charge of 20 PSI, it requires air pressure adjustment to two PSI below the pressure switch cut-in. This makes the RL2A a practical choice for smaller homes, cottages, or retrofit projects where space is at a premium but reliable pressure control remains essential. The RL2A’s small footprint makes it easier to install near the well or pump, helping minimize line losses while providing smoother transitions during pump cycles.
The combination of a robust diaphragm, corrosion-resistant materials, and straightforward setup supports long-term performance. For households seeking a balance between compact size and reliable pressure stabilization, the RL2A offers a proven Red Lion solution with familiar performance characteristics in a smaller form factor.
Red Lion RL4A 4.5-Gallon Inline Tank
The Red Lion RL4A is a 4.5-gallon inline pressure tank designed to maintain consistent water pressure and diminish water hammer in well systems. Like other Red Lion models, it features a heavy-duty 20-gauge steel tank and a 304 stainless steel water connection with the patented leak-safe technology and a high-performance butyl rubber diaphragm with a propylene liner. The RL4A ships pre-charged to 20 PSI, and user adjustment to two PSI below the pressure switch cut-in is recommended for optimal operation. This tank fits smaller to mid-sized homes or multi-point well systems, providing a reliable balance of capacity and compact footprint for quick installation near the well or control panel.
With its durable construction and field-proven design, the RL4A supports longevity in varied climates and installation environments. Routine maintenance, including checking the diaphragm and ensuring proper air charge, helps sustain peak efficiency and steady pressure throughout everyday use.
Generic 160L Pressure Tank, Stainless Steel
This 160-liter stainless steel pressure tank combines substantial capacity with corrosion resistance, making it suitable for larger residential or small commercial water systems. The 304 stainless steel body offers excellent durability and resistance to frost and wear, while a three-arc base design provides strong load-bearing capacity and anti-dumping stability. The unit is designed for automation, using pressure to auto-start and stop the pump as water demand changes. The system emphasizes safety: it’s designed for potable water standards and minimizes leak points with seal-tight threading and durable construction. It’s an appealing choice for homes with higher daily water usage or outdoor installations where temperature swings are common.
Although larger, this model remains compatible with standard well pump connections and provides a robust backbone for uninterrupted water supply. Users should pay attention to inlet/outlet sizing and ensure appropriate pre-charge settings to match the pressure switch, enabling smooth, efficient cycling and consistent water pressure throughout the home.
Redford Supply Co. Cold Snap Round Tank Cover
The Redford Supply Co. Cold Snap Round Tank Cover is designed to insulate outdoor pressure tanks and protect them during freezing weather. The 8″ diameter by 12″ height design provides coverage for typical well tanks and can help maintain water temperature, reducing the risk of freezing in cold climates. The cover is UV-resistant and weatherproof, ensuring long-term protection for outdoor tanks.

Buying Guide: Key Purchase Considerations For Well Pump Bladders And Tanks
- Capacity and system load: Choose a tank size that matches household water usage and peak demand. Larger homes or higher flow rates benefit from bigger tanks like 20 gallons, while smaller setups can rely on compact tanks to reduce space needs.
- Working pressure and pre-charge: Verify the diaphragm’s compatibility with your pump’s cut-in and cut-out pressures. Most pre-charged tanks ship with a standard 20 PSI and require adjusting the air charge to two PSI below the switch setting.
- Material and durability: Stainless steel tanks offer excellent corrosion resistance and longer life in some environments. Steel tanks with leak-safe connections are common and reliable for US residential use.
- Water quality certifications: For drinking-water safety, look for NSF/ANSI/CAN approvals indicating compliance with safety standards for potable water.
- Installation environment: Outdoor installations need weatherproof covers and proper insulation, particularly in regions with freezing temperatures. Ensure outdoor components have UV resistance and adequate protection.
- Pressure stability and pulsing: Accumulator models and bladder tanks can smooth water flow and reduce pump cycling, increasing pump life and reducing energy use. Consider models designed for steady flow in your water system.
- Maintenance and accessibility: Check for serviceable diaphragms, easy-to-reach air charge valves, and clear guidance for regular maintenance to maximize lifespan and performance.
- Compatibility: Ensure the chosen tank matches your pump size and the existing plumbing connections (MNPT vs FNPT, 1-inch vs 3/4-inch). Adapters are sometimes needed for retrofits.
- Warranty and support: Prefer brands with solid warranties and readily available customer support to address diaphragm wear and leakage concerns over time.
Overall, selecting the right bladder or pressure tank for a well pump hinges on balancing capacity, durability, and the system’s pressure needs. Inline tanks and compact options fit tight spaces, while larger units offer greater buffer against pressure fluctuations. For outdoor installations, insulated covers add resilience in winter. When evaluating a product, consider the combination of materials, pre-charge guidance, and certifications to ensure safety and long-term reliability for your home’s potable water supply.
