Red Lion RL34A 34-Gallon Vertical Tank
The RL34A is a vertical, pre-charged pressure tank designed for well pump systems. It maintains water pressure when the pump is off, helping to stabilize flow and extend pump life. The tank uses a heavy-duty 20-gauge steel shell and a 304 stainless steel water connection with patented leak-safe technology. A high-performance butyl rubber diaphragm and a polypropylene liner are configured to resist wear and chemicals in drinking water applications. It ships pre-charged to 20 PSI for transport, with instructions to top off air pressure to two PSI below the pressure switch cut-in setting after installation.
Key considerations include NSF/ANSI/CAN 61 and NSF/ANSI/CAN 372 certifications, ensuring safe water contact. The combination of a durable shell and a reliable diaphragm aims to reduce short cycling and maintain consistent pressure across a wide range of well depths. If you have a larger home or higher water demand, the 34-gallon capacity provides a balance of steady pressure and system efficiency. Installation requires standard 1-inch FNPT connections and attention to proper pre-charge tuning for your switch settings.
Red Lion RL20A 20-Gallon Vertical Tank
The RL20A offers a compact 20-gallon vertical design with a thermoplastic base and a 1-inch FNPT elbow system connection. Like the RL34A, it is built to support well pump applications, keeping pressure steady when the pump cycles down. It employs the same class-leading components: a 20-gauge steel tank, a 304 stainless steel water connection, a modern diaphragm, and a polypropylene liner. It ships pre-charged to 20 PSI for transport, with instructions to top off air pressure to two PSI below the cut-in setting. This model is a favorable option where space is at a premium but higher capacity is still desired.
Choosing the RL20A is a practical middle-ground decision for households with moderate water demand. The unit’s durability, corrosion resistance, and leak-safe design align with common well systems found across American homes, especially where space constraints are a consideration.
Amtrol WX-202 Well Pressure Tank
Amtrol’s WX-202 is a well pressure tank focused on durability and reliability. It features a high-strength steel shell and a virgin polypropylene inner liner, designed to resist cracking and flaking while preserving water quality. A unique positive hoop ring seal secures the diaphragm and liner, contributing to enhanced structural integrity. This model emphasizes long-term performance and consistent pressure, making it a solid choice for households with demanding pump cycles or hard water conditions. Installation compatibility and proper pre-charge settings should be matched to your specific pump and switch configuration.
Red Lion RL6AH 6-Gallon Horizontal Tank
The RL6AH is a compact horizontal pre-charged tank with a mounting bracket and thermoplastic stand, designed for well pump setups with a 3/4-inch MNPT connection. While smaller in capacity, its horizontal form factor makes it easy to integrate into tight spaces or rotate for mounting alongside a pump. It uses a heavy-duty steel shell with a leak-safe water connection and a robust butyl rubber diaphragm, similar to larger Red Lion models. Pre-charge and air adjustments follow standard guidelines for maintaining proper switch operation, ensuring efficient pump cycling.
WaterWorker HT-30B Vertical Tank
WaterWorker’s HT-30B is a 30-gallon vertical tank built to NSF standards. The diaphragm is designed to flex rather than crease, aiming to deliver long-term reliability under typical water system cycling. The polypropylene liner is chosen to minimize taste and odor transfer to drinking water. This model suits households needing a larger tank without stepping up to a full commercial size. As with other tanks, ensure correct pre-charge and switch settings to optimize performance for your pumping system.
Buying Guide: Key Purchase Considerations
- Capacity vs. demand: Higher-capacity tanks reduce pump cycling but require more space. Evaluate peak household usage, irrigation needs, and well drawdown depth.
- Tank type and orientation: Vertical tanks save floor space; horizontal tanks fit tight areas. Ensure compatibility with existing piping and mounts.
- Materials and corrosion resistance: Look for steel shells with stainless connections and reliable diaphragms. These factors influence lifespan in hard water or chlorinated systems.
- Pre-charge and switch settings: Correct pre-charge pressure and switch cut-in/cut-off settings are essential for stable pressure and pump life. Refer to your pump’s manual for recommended values.
- Certifications and safety: NSF/ANSI/CAN 61 and 372 approvals indicate suitability for drinking water contact and safe material composition.
- Maintenance and replacement: Consider diaphragm integrity and liner material; some models offer easier replacement parts or extended warranties.
- Space and installation constraints: Ensure adequate clearance for service access, as well as mounting options if space is limited.
- System compatibility: Check connection size (1-inch FNPT, 3/4-inch MNPT, etc.) and ensure your pump and plumbing match.
In evaluating pressure tanks, focus on durability, certifications, and the compatibility with your well pump configuration. For households with higher water demand or larger lots, larger vertical tanks such as the 34-gallon RL34A offer robust performance. For compact spaces, horizontal options like the RL6AH provide versatility. The Amtrol WX-202 and WaterWorker HT-30B models present solid alternatives with strong diaphragms and NSF-compliant components. Always align tank pre-charge and switch settings with the pump control scheme to maximize efficiency and pump longevity.
