Red Lion RL20A Vertical Pre-Charged Tank
The RL20A is a 20-gallon vertical pre-charged tank designed to maintain stable water pressure when a well pump is idle. It features a heavy-duty 20-gauge steel body and a 304 stainless steel water connection with patented leak-safe technology. A butyl rubber diaphragm and a polypropylene liner ensure durability and reduce water contamination risks. The tank ships pre-charged to 20 PSI and requires topping off to two PSI below the system’s pressure switch cut-in. It is NSF/ANSI/CAN 61 and 372 certified for safe, clean drinking water connections, making it suitable for residential well systems.
WaterWorker 25009 20-Gallon Vertical Tank
This 20-gallon WaterWorker tank emphasizes a seamless butyl diaphragm design that flexes rather than creases, improving longevity. The polypropylene liner in the reservoir resists flaking and does not impart taste or odor to the water. NSF-listed under ANSI/NSF Std 61, this tank prioritizes clean water delivery and reliable pressure support for typical residential wells. It is a solid option for homeowners seeking a durable, non-bladder alternative with steady performance characteristics.
Amtrol WX-202 Well Pressure Tank
The WX-202 features a high-strength steel shell with a virgin polypropylene inner liner that resists cracking and flaking. A unique positive hoop ring seal secures the diaphragm and liner, delivering added strength and reliability. This design supports consistent water pressure while safeguarding against common issues like liner separation. Suitable for residential wells that require robust construction and long-lasting performance in variable water conditions.
Amtrol WX-203 Well-X-Trol
The WX-203 (Well-X-Trol) uses a high-strength steel shell and a virgin polypropylene inner liner that resists cracking, chipping, flaking, or peeling. The steel system connection is designed to withstand aggressive water conditions, offering reliable performance in challenging water profiles. This tank is a recommended option for households needing a sturdy, long-lasting supply with consistent pressure control.
VEVOR 34-Gallon Vertical Tank
The VEVOR model provides a large 34-gallon capacity, ideal for homes with higher daily water use or where longer intervals between pump cycles are desirable. It uses a 1-inch NPT connector and a robust carbon steel body with a pre-charge pressure around 36.2 PSI. While not intended for drinking water, this tank helps stabilize pressure in whole-house water systems and reduces pump cycling for consistent performance across households with larger storage needs.
Buying Guide: Key Purchase Considerations For Well Tanks
- Capacity and system needs: Match tank size to daily water use and pump characteristics. Larger tanks reduce cycling but require space and existing plumbing considerations.
- Diaphragm vs bladder: Diaphragm tanks (like the WaterWorker and Amtrol examples) are generally more durable in variable water chemistry; bladder tanks may offer quicker response in some setups but can be prone to failure over time.
- Materials and durability: Look for steel shells with robust liners. Stainless steel connections reduce corrosion risk, while polypropylene liners resist chemical wear and taste changes.
- Pre-charge pressure: Tanks ship pre-charged; ensure the air charge matches two PSI below your pressure switch setting for optimal performance.
- Certifications and safety: NSF/ANSI certifications indicate compliance with drinking water safety standards. If drinking water contact is a concern, prioritize NSF-listed models.
- Installation environment: Consider frost-prone areas; some tanks are not rated for freezing conditions. Indoor installations can extend lifespan in colder climates.
- Maintenance and warranty: Check for long-term warranties and diaphragm integrity features. Regular inspection helps prevent leaks and pressure loss.
- Compatibility with existing pumps: Verify inlet/outlet sizes (common options include 1-inch MNPT/FNPT) and overall dimensional fit within your well system layout.
