## Product: WaterWorker 20 Gallon Well Tank
**Brand:** Water Worker

## Pros
- The WaterWorker 25009 tank is well-made with durable construction expected to last several decades.
- Features a sturdy metal base instead of plastic, adding to its robustness.
- Equipped with quality metal fittings and a strong air inlet screw cap for reliable performance.
- The freestanding vertical design requires no bracket for pump attachment, simplifying installation.
- Offers a larger 20-gallon capacity compared to older models, making it versatile for replacement needs.
- Includes a useful cross-reference capacity guide to help match and replace other tanks easily.
- Comes preset with a 39 psi bladder pressure, suitable for typical 40-60 pressure switch settings.
- One-inch pipe inlet and outlet ensure efficient flow rates for well systems.
- Installation is straightforward, especially with professional assistance.
- Overall provides excellent value for durability and performance compared to previous options.

## Cons
- Tanks with internal diaphragms are disposable when the diaphragm fails, as no replacement is available, requiring full tank replacement.
- Annual maintenance is necessary to check and adjust air pressure to prevent pump short cycling and overheating, or you risk system issues.
- The finish quality can be damaged by common PVC cement, which may affect aesthetics and protection over time.
- While durable, users should verify their system needs carefully (number of users, pressure requirements) for optimal tank performance.
- Some users may find the tank heavier than plastic alternatives, though this is a trade-off for durability.

## Bottom Line

The WaterWorker 25009 20-gallon vertical well tank is a solid, durable choice for anyone needing a reliable tank with a larger capacity than older models. Its metal construction and thoughtful design make it a trustworthy performer that should last years with proper maintenance. Keep in mind the bladder is not replaceable, so plan for eventual full tank replacement if needed. If you want a tank that's easy to install and offers great value for the price, this model fits the bill nicely. Just remember to maintain air pressure annually to keep your pump happy and healthy.

If you're looking for alternative tanks with replaceable diaphragms or a different capacity range, you might want to explore other brands, but for straightforward durability and ease, this is a strong contender.
