Red Lion RL6AH 6-Gallon Horizontal Pressure Tank - Reliable Water

In this review the Red Lion RL6AH 6-gallon horizontal pressure tank is evaluated for homeowners with a shallow well or a small pressure system who need consistent water pressure and reduced pump cycling. The biggest reason to buy is its practical combination of a pre-charged vessel, pump mounting bracket and a thermoplastic stand that simplifies installation and protects floors. The tank is designed to maintain pressure between pump cycles, which helps appliances run smoothly and extends the life of a well pump.

Key Features

• Pre-charged tank: The unit is shipped pre-charged to 20 PSI so initial setup only requires topping off the air charge to match your pressure switch settings.
• NSF certified: Materials and construction meet NSF/ANSI/CAN 61 and NSF/ANSI/CAN 372 testing for safe, clean drinking water.
• Durable construction: Heavy-duty 20-gauge steel shell and a propylene liner resist corrosion and provide a long service life when installed properly.
• Leak-safe connection: 304 stainless steel water connection with patented leak safe technology reduces risk of leaks at the system fitting.
• Includes mounting hardware: Pump mounting bracket and thermoplastic stand are included so you can mount a pump directly to the tank and keep the tank off the floor to prevent condensation marks.

Who It's For

The RL6AH is best suited to homeowners on well systems with light to moderate demand who want a compact tank that can handle about two fixtures running at once. Its 1.9 gallon drawdown at 30/50 PSI and 3/4 in MNPT straight system connection make it appropriate for small houses, cottages, or utility applications.

It is not intended for high-demand properties or commercial systems that require larger drawdown or higher capacity. Buyers seeking a tank with a different orientation, larger volume, or a specific factory air pressure setting should look at other models.

Pros & Cons

Pros

• Pre-charged to simplify setup and reduce initial adjustments.
• NSF certifications mean the tank is suitable for potable water systems.
• Includes pump mounting bracket and stand for a neat, compact installation.

Cons

• Some customers report cosmetic dents or broken plastic components on delivery, so inspect packaging on arrival.

Specifications
