Red Lion RL2A 2-Gallon Inline Pressure Tank - Compact Well Tank

In this review of the Red Lion RL2A pressure tank, the bottom line is simple: it is a compact, practical inline tank for homeowners and hobbyists who want to stabilize well pump pressure or reduce water hammer without a lot of fuss. The RL2A is pre-charged for transport and uses a durable steel shell with a butyl diaphragm and 304 stainless connection, so the single biggest reason to buy is reliable pressure support in a small footprint that can be installed inline or added in series for greater capacity.

Key Features

• Pre-charged to 20 PSI: The factory charge simplifies shipping and initial handling, and can be topped off easily to match your pressure switch settings.
• Heavy-duty construction: A 20-gauge steel tank with propylene liner and butyl diaphragm provides corrosion resistance and a long service life.
• 304 stainless water connection: The straight 3/4 in MNPT connection with Red Lion leak safe technology helps reduce leak points at the fitting.
• Compact 2-gallon capacity: The small footprint makes it suitable for inline installation where space is limited or for adding extra capacity in series or parallel.
• Certified for drinking water: WQA NSF/ANSI/CAN 61 and CAN 372 testing means the tank is approved for potable water systems.
• 0.7 gallon drawdown at 30/50 PSI: Provides usable pressure reserve to reduce pump cycling on small systems and pressure boosting applications.

Who It's For

The RL2A is best for homeowners with shallow well or booster pump setups who need a compact inline tank to reduce pump cycling and water hammer. It is also useful for installers who want a certified potable-water tank that can be added in series or parallel to increase system capacity without a large footprint.

Those who need large drawdown or whole-house storage should look at larger tanks instead; the RL2A's 0.7 gallon drawdown is intended for pressure stabilization rather than long-duration storage. Also, buyers who require absolute dent-free cosmetic packaging for visible installs should be aware that shipping damage has been reported by some customers.

Pros & Cons

Pros

• Solid build quality with a 20-gauge steel shell and stainless water connection for corrosion resistance.
• Easy inline installation and flexible placement options, including series or parallel configurations.
• Certified for drinking water, making it safe for potable systems.
• Pre-charged for convenience and simple to top off to match your pressure switch.

Cons

• Small drawdown (0.7 gallon) limits usefulness as a primary storage tank for larger homes.
• Some customers report dents or damaged plastic parts upon arrival, so inspect on delivery.
