Red Lion RL20A 20-Gallon Pressure Tank
The Red Lion RL20A is a vertical pre-charged pressure tank designed for use with well pump systems. It features a heavy-duty 20-gauge steel shell and a 304 stainless steel water connection with patented leak-safe technology. The tank includes a high-performance butyl rubber diaphragm and a polypropylene liner to manage drinking-water safety. It ships pre-charged to 20 PSI, with setup requiring the air pressure to be adjusted to 2 PSI below the pressure switch cut-in setting. Applications center on maintaining consistent pressure when the pump cycles off, reducing short cycling and improving pump longevity.
Key specs and considerations:
– Certification: NSF/ANSI/CAN 61 and NSF/ANSI/CAN 372 for drinking water safety
– Connections: 1-Inch FNPT elbow system for flexible plumbing layouts
– Materials: 20-gauge steel, stainless water connection, durable diaphragm
Amtrol WX-202 Well-X-Trol 20 Gallon
The WX-202 Well-X-Trol is a classic 20-gallon well pressure tank designed for reliable well water systems. It ships factory pre-charged at 38 PSI and uses a robust 1″ NPT system connection. The tank is built to withstand demanding water conditions and features a durable exterior suitable for standard residential installations. It supports consistent water pressure and helps curb pump cycling by maintaining a steady air-to-water balance.
Highlights include:
– Pre-charge: 38 PSI
– Connection: 1″ NPT
– Operating range: up to 200°F
– Construction emphasizes durability and long service life
iSpring T20M 20 Gallon Pre-Pressurized Tank
Designed for RO systems, the iSpring T20M 20-gallon tank combines storage capacity with versatile placement. The unit is built from quality materials and third-party tested to meet NSF and ANSI standards. It includes shut-off valve, tank connector, and a stand, delivering a complete package for quick installation. The tank supports either vertical or horizontal positioning, accommodating tight spaces or specific installation preferences in kitchens or basements where RO storage is needed.
Key points:
– Includes essential components for immediate setup
– Meets NSF/ANSI standards per independent testing
– Flexible orientation for space-constrained areas
ELEVZO 20Gal Water Pressure Tank
The ELEVZO 20Gal tank emphasizes safety with a 304 stainless steel port rated at 218 PSI, enabling secure connections to common well and pump setups. A food-grade polypropylene liner protects drinking water from metal contact, ensuring taste and purity. The shell is a heavy-duty carbon steel with powder coating for corrosion resistance, and the plastic base helps minimize floor rust and condensation in basements or utility rooms.
Considerations:
– Drinking-water safety certifications for the liner
– High-pressure port capacity supports robust pumping systems
– Rust-resistant construction and base design improve longevity
APEC TANK-20 20 Gallon Pre-pressurized Tank
APEC WATER’s TANK-20 provides pre-pressurized storage for RO systems and other pressure-demand applications. It holds up to 14.8 gallons of water and offers vertical or horizontal discharge with an included stand for stable placement. The bladder is food-grade, and the tank is certified for quality, safety, and durability. This makes it suitable for households seeking a compact storage solution integrated with RO filtration.
Strengths include:
– Pre-pressurized design for quick startup
– Versatile orientation and included stand
– Food-grade bladder and compliance for safe use
Buying Guide: Key Considerations for a 20 Gallon Pressure Tank
- Application compatibility: Confirm whether you need the tank for a well-pump system, an RO storage application, or a mixed-use setup. Some tanks emphasize drinking-water safety with certified liners and diaphragms, while others focus on high-pressure tolerance or easy integration with standard plumbing.
- Pre-charge and set-up: Check the factory pre-charge PSI and how easy it is to top off the pressure to match your switch cut-in setting. Improper pre-charge can cause short cycling or sluggish pressure recovery.
- Materials and safety: Stainless steel ports, food-grade liners, and NSF/ANSI certifications indicate suitability for drinking water. Consider rust protection, diaphragm vs. bladder design, and the durability of the shell for long-term use.
- Connection size and configuration: Ensure compatibility with 1″ NPT/ FNPT connections and elbow options. Some tanks offer flexible mounting or horizontal/vertical installation to fit tight spaces.
- Pressure rating and temperature: Look for a tank rated for your operating pressure and ambient temperature. A higher rating provides headroom for pressure surges and heat from adjacent equipment.
- Physical footprint: Measure the available floor space to ensure the tank fits without obstructing access to other equipment or utilities.
- Maintenance and warranty: A robust warranty and accessible diaphragms or liners simplify future service. Consider how easily components can be replaced or resented.
- Certification and safety: NSF/ANSI certifications and drinking-water safety features are important for homes using potable water. If you operate a farm or irrigation system, other certifications may be relevant.
