Red Lion RL20A - 20-Gallon Vertical Pressure Tank with Almond Finish, 1-Inch FNPT Elbow

Overview

The Red Lion RL20A is a 20-gallon vertical, pre-charged pressure tank designed to support well pump systems and deliver steady water pressure when the pump cycles off. With an almond finish and rugged construction, it blends into home plumbing while providing durable performance for everyday tasks like showering, running a dishwasher, or powering a washing machine.

In real-world use, a pressure tank stores water between the diaphragm and liner, smoothing out pressure fluctuations so fixtures receive more consistent flow. This setup can help reduce the number of times the pump starts, potentially extending the pump’s lifespan and delivering reliable pressure during peak usage periods.

Why it’s reliable

• Heavy-duty 20-gauge steel tank paired with a 304 stainless steel water connection for durability and leak-safe performance.
• High-performance, variable geometry butyl rubber diaphragm and polypropylene liner work together to store water and maintain steady pressure.
• NSF/ANSI/CAN 61 and 372 certified by WQA, confirming safety for drinking-water systems in compliant setups.

Key specifications

• 20-gallon vertical tank with 7.2 gallon drawdown at 30/50 PSI.
• 1" FNPT elbow system connection; compatible with series or parallel installations to scale capacity.
• Maximum working temperature 194°F; maximum working pressure 150 PSI.
• Pre-charged to 20 PSI for transport; air charge should be adjusted to 2 PSI below the pressure switch cut-in using a bicycle pump (gauge not included).
• Thermoplastic base lifts the tank off the floor to reduce condensation and floor staining.

Practical use and benefits

Designed to work with a well pump system, the RL20A helps maintain consistent water pressure even when the pump is idle. The almond-painted exterior gives a polished look, while the robust internals are built to handle daily household needs without frequent maintenance.

• Supports up to six fixtures running simultaneously, making it suitable for homes with multiple taps or appliances active at once.
• Series or parallel installation options enable you to tailor capacity and flow to your home’s layout and demand.

Notes on setup and maintenance

The unit is designed for low maintenance, with a factory pre-charge and clear setup instructions. Always follow the included guidance to ensure safe operation and optimal performance within your water system.
