This tank is ideal for homeowners looking to stabilize water flow and extend pump life, especially in households with multiple water-using appliances.
Standout features include a robust butyl rubber diaphragm and a corrosion-resistant powder-coated steel shell.

The Amtrol WX-202 Well Pressure Tank is a top-tier residential water system component designed for homeowners who demand reliability and consistent water pressure. With a 20-gallon capacity and a corrosion-resistant virgin polypropylene liner, this tank is built to last in demanding well water applications.
Its standout feature is the exclusive butyl diaphragm combined with a positive hoop ring seal, which outperforms conventional water chamber designs. The welded stainless steel air valve prevents air loss, ensuring steady pressure without frequent adjustments. Users report easy installation and long-lasting performance, with many replacing old tanks that lasted 25 years or more.
Build quality is exceptional: a deep-drawn high-strength steel shell keeps weight low while providing durability. The appliance-like blue finish allows installation in living spaces, not just basements. The tank is pre-pressurized at 38 psi, making setup straightforward when set 2 psi below the cut-in pressure.
Potential drawbacks include its footprint (15 inches square) which may not fit extremely tight spaces, and the need to adjust pressure for specific systems. However, these are minor compared to the overall reliability and 7-year warranty.
Verdict: The Amtrol WX-202 is a premium investment for anyone seeking a hassle-free, long-lasting well pressure tank. Its corrosion-resistant materials and proven design make it a top choice for both new installations and replacements.
Pros
- Sturdy build with corrosion-resistant coating ensures long life
- Simple setup with clear instructions and universal fit
- Optimizes pump operation for reliable flood prevention
- Space-saving horizontal profile fits under low beams and in cramped areas
- Requires minimal upkeep once properly adjusted
Cons
- Initial air pressure may need adjustment from factory settings (typical for pressure tanks)

The Reliance 20 Gallon Horizontal Pressure Tank is a steel accessory engineered to boost sump pump performance and safeguard basements from flooding. It targets homeowners who need dependable water removal in confined spaces like crawl spaces or under-mobile home areas.
Standout features include universal compatibility with most sump pump systems and tool-free installation. The powder-coated steel resists rust and wear, while the 20-gallon capacity supports consistent pump cycling. Real-world feedback highlights the need to adjust the pre-charge air pressure from 56 psi down to 28 psi for proper operation, a common step for diaphragm tanks.
Build quality is robust, with a blue powder-coated finish that holds up in damp environments. The horizontal design measures 27.125 by 17.375 inches, but note that adding the feet and top bracket increases height to about 17.5 inches. This can make it a tight fit under beams as low as 16 inches, so measure your space carefully.
A minor drawback is the factory air pressure setting, which requires a simple bleed-down. Additionally, with only a few reviews so far, long-term reliability data is limited. However, the tank performs well once set up, reducing pump short-cycling and protecting against water intrusion.
Overall, the Reliance 20 Gallon Horizontal Pressure Tank is a solid choice for budget-conscious homeowners who need a compact, durable tank for their sump pump system. It delivers on its promises of easy installation and effective performance, making it a worthwhile investment for flood prevention.
Buying Guide
Capacity and Drawdown
One of the most important factors when choosing a challenger pressure tank for sale is its capacity. Tanks are rated by total gallon size, but the usable drawdown water is what matters. A 20-gallon tank may only deliver 5–7 gallons before the pump kicks in. For a small home or irrigation system, the Reliance Pressure Tank – Pre-Charged offers a 20-gallon size that fits tight spaces. For larger demands, the 52-gallon vertical tank provides more drawdown. Check our well pressure tank sizing to match your pump flow rate.
Diaphragm and Liner Material
The diaphragm separates water from air inside the tank. Reliance models use a butyl rubber diaphragm, which is durable and resistant to flex fatigue. Amtrol uses a virgin polypropylene liner that will not crack, chip, or peel. Both materials prevent waterlogging and extend tank life. For long-term reliability, the Amtrol WX-202 Well Pressure Tank is a top choice with over 650 verified reviews and a 4.8-star rating.
Orientation and Installation Space
Pressure tanks come in vertical and horizontal configurations. Vertical tanks like the Reliance 20-gallon and 52-gallon save floor space but need headroom. Horizontal tanks fit under low ceilings or in crawl spaces. The Reliance Pressure Tank 20 Gallon Horizontal is designed for sump pump systems but can also serve as a compact well tank. Measure your available area before buying. Most tanks require a minimum clearance around the pipe connections.
Compatibility with Well Pumps
Ensure the challenger pressure tank you choose works with your pump type. Reliance tanks are pre-charged and compatible with jet pumps, submersible pumps, and booster systems. Amtrol tanks feature a positive hoop ring seal that secures the diaphragm under high pressure. If you have a deep well pump, a larger tank with a 1-1/4 inch pipe connection (like the Reliance 52-gallon) reduces cycling. For more details, visit our pressure tanks category page.
Final Thoughts
After reviewing the top challenger pressure tanks for sale in September 2026, we recommend the Reliance Pressure Tank – Pre-Charged for its compact size and proven performance in small homes, RVs, and garden systems, and the Amtrol WX-202 Well Pressure Tank for its superior liner and long-term reliability in well pump applications. Both options deliver consistent water pressure and are backed by strong customer ratings.
Frequently Asked Questions
How does a challenger pressure tank work?
A pressure tank stores water under compressed air. When you open a faucet, the air pushes water out without the pump starting. This reduces pump cycling and maintains steady pressure. The tank recharges when the pump turns on. For a deeper explanation, read how a well pressure tank works.
What size challenger pressure tank do I need?
The right size depends on your pump’s flow rate and the tank’s drawdown. A general rule is to select a tank that provides at least 1 minute of run time for your pump. For a 10 GPM pump, a 20-gallon tank often works; for higher flow, a 52-gallon tank is better. Use our sizing guide for a precise match.
Can I install a challenger pressure tank myself?
Yes, many homeowners install pressure tanks with basic plumbing skills. The tanks come pre-charged with air at the factory. You need to connect the tank to your system using a tee kit and adjust the pressure switch. Always follow the manufacturer’s instructions and local codes. For complex setups, consider professional installation.
What is the difference between Reliance and Amtrol pressure tanks?
Reliance tanks feature a butyl rubber diaphragm and powder-coated steel shell, available in multiple sizes and orientations. Amtrol tanks use a virgin polypropylene liner with a corrosion-resistant design. Amtrol has a longer track record (over 650 reviews), while Reliance offers more budget-friendly options. Both brands are reliable for 2026.
