Buying Guide: What to Look for in a Pressure Tank for Irrigation
Tank Material and Corrosion Resistance
A pressure tank lives in a wet environment, often outdoors or in a damp basement. The shell should be tough enough to resist rust and dents. Many top choices use heavy-gauge carbon steel with a corrosion-resistant coating. For the inner liner, materials like virgin polypropylene or butyl rubber prevent water from contacting the steel, eliminating rust and flaking. Look for tanks with a proven liner system, such as the Amtrol WX-202, which incorporates a butyl diaphragm and polypropylene liner.
Capacity and Drawdown: Matching Your Irrigation Demand
Gallons alone don’t tell the whole story; you need to know the drawdown, the amount of usable water the tank delivers before the pump kicks in. Irrigation systems with multiple sprinklers or drip zones typically require a larger drawdown to avoid short cycling. A tank like the VEVOR 20-gallon vertical model provides ample reserve for whole-home and farm applications. For smaller gardens, a compact 4- or 5-gallon tank paired with a booster pump may be enough. Check the manufacturer’s drawdown ratings at your pressure switch settings (usually 30/50 or 40/60 PSI).
Pre-Charge Pressure and Compatibility with Your Pump
Every tank comes with a factory pre-charge, typically around 20 PSI, but you must adjust it to 2 PSI below your pump’s cut-in pressure. If you have a 30/50 PSI pressure switch, you should set the tank’s air charge to 28 PSI. Failing to match this leads to waterlogging or poor performance. Some tanks, like the Red Lion RL4A, include clear instructions and a 304 stainless steel connection for leak-free installation. Always use a bicycle pump or compressor on the Schrader valve to fine-tune the pressure.
Connection Type and Ease of Installation
Most tanks use a 1-inch NPT male connector, which fits standard plumbing. For systems with limited space, in-line tanks (like the Red Lion RL4A) allow versatile mounting either vertically or horizontally. Some products come as complete pump/tank combos, such as the FOTING 1.5HP Shallow Well Pump with Pressure Tank. These simplify installation by integrating the pump, tank, pressure switch, and gauge. If you prefer a separate tank, ensure it includes a galvanized or stainless steel tee and a pressure relief valve for safety.

Frequently Asked Questions
What size pressure tank do I need for my irrigation system?
You will want a tank large enough to provide at least 1-2 minutes of drawdown to prevent short cycling. For a typical 10-15 GPM irrigation pump, a 20-gallon tank (with about 5-6 gallons of drawdown) is a common choice for medium properties. For small gardens, a 4-5 gallon tank may be enough. Always check the manufacturer’s drawdown chart for your pressure settings.
How often should I check the air pre-charge in my pressure tank?
We recommend checking the air pre-charge at least twice a year, ideally before the irrigation season begins and again mid-season in 2026. Turn off the pump, drain the tank, and use a tire gauge on the valve. If the pressure is below the recommended level (typically 2 PSI below the pump cut-in), add air with a compressor or bicycle pump.
Can I use a pressure tank with a shallow well pump?
Absolutely. Many shallow well pumps, like the FOTING or Aquastrong models featured in this review, come equipped with an integrated pressure tank. If you have a separate pump, you can add an inline tank such as the Red Lion RL4A. Just ensure the tank’s inlet is compatible with your pump’s outlet, and set the air charge correctly.
Do I need a pressure relief valve on my pressure tank?
Yes. Most local codes and safety guidelines require a pressure relief valve rated at least 100 PSI (or as specified by the tank). This valve releases excess pressure if the pressure switch fails, preventing tank rupture. The VEVOR 20-gallon tank, for example, notes that a relief valve is not included but is essential for safe operation.
