Red Lion RL20: A Good Budget Pick for Small Wells

The Red Lion RL20 is a practical choice for smaller residences, such as seasonal cabins, tiny homes, or small hobby farms. It offers basic, efficient functionality at a price point that respects a tighter budget.

Despite the lower cost, it does not sacrifice the core function of water regulation. It features a reliable diaphragm design that provides steady pressure for daily chores like washing dishes or running a bathroom sink.

This tank is the ideal solution for situations where the budget is constrained but a new, functional tank is essential. It delivers reliable performance for basic, light-duty water usage requirements.

Choosing the Right Tank Size for Your Well Pump

A common misconception is that a larger tank is always better. In reality, the tank size must be matched to the capacity of the well pump to prevent “short-cycling.” Short-cycling occurs when the pump turns on and off too frequently, which can burn out the motor in a very short amount of time.

• Small households: A 20-gallon tank is usually sufficient for homes with low occupancy and limited water demand.
• Large households: Homes with multiple bathrooms, heavy laundry usage, or irrigation needs require a larger tank to maintain a proper pump run-time.
• Consulting the manual: Always check the pump manufacturer’s recommendations for the required “drawdown” capacity before purchasing a replacement.

The bottom line is that the tank must hold enough water to allow the pump to run for at least one to two minutes during a cycle. Match the tank to the pump, not just to the size of the house.

Steel vs. Composite Tanks: What’s the Difference?

The choice between steel and composite (fiberglass) tanks generally comes down to the environment and the water quality. Steel tanks are the traditional choice, known for their structural strength and reliability, but they are vulnerable to external corrosion if placed in damp areas.

Composite tanks offer a clear advantage in rust resistance, making them ideal for coastal areas or damp crawlspaces. They are significantly lighter than steel, which simplifies the physical labor of installation.

However, composite tanks can be more susceptible to physical impact damage, such as a bump from a heavy tool or a dropped object. Steel tanks are generally more robust when it comes to accidental knocks in a busy utility room.

A Simple Yearly Check-Up for Your Pressure Tank

Maintaining a pressure tank does not require specialized training, but it does require a bit of vigilance once a year. The most critical task is checking the “pre-charge” air pressure in the tank using a standard tire gauge.

Follow these steps for a basic health check: 1. Turn off power to the well pump at the breaker. 2. Open a faucet near the tank to drain all the water out completely. 3. Check the air valve (usually hidden under a cap on top) with a tire gauge to see if it matches the manufacturer’s recommended pressure, typically 2 PSI below the pump cut-in pressure.

If the gauge reads zero, the tank has lost its air charge and needs to be repressurized with an air compressor. Taking ten minutes to perform this check annually can prevent the bladder from stretching and failing prematurely, saving hundreds of dollars in repair costs.

A well-maintained pressure tank acts as the heartbeat of a home’s water system, ensuring that everything from the kitchen faucet to the garden hose functions as expected. By taking the time to match the tank size to the pump and performing simple annual pressure checks, the longevity of the entire system is significantly increased. Choose the model that best suits the physical space and specific water demands of the household, and the home will enjoy consistent, reliable pressure for years to come.
