Buying Guide for Booster Tanks
Choosing the right booster tank for water pressure requires careful consideration of your system’s demands. Here are three key factors to evaluate before making a purchase.
Tank Capacity and Drawdown
The tank’s total capacity and drawdown (the amount of water stored before the pump kicks on) directly affect how often your pump runs. Larger tanks like the 30-gallon WaterWorker HT-30B provide more reserve water, reducing pump cycles and extending pump life. For sizing guidance, refer to our well pressure tank sizing.
Material and Durability
A well-built tank resists corrosion and wear. Look for a steel shell with a corrosion-resistant liner (polypropylene or butyl rubber). The Amtrol WX-202 features a virgin polypropylene liner that won’t crack or flake, while the Reliance tank uses a butyl diaphragm for reliable performance. These materials isolate water from the steel shell, preventing rust.
Pre-Charge Pressure and Compatibility
Most tanks come pre-charged with air, but you must adjust it to match your pump’s pressure switch settings. The Red Lion RL4A is pre-charged to 20 PSI and requires topping off to 2 PSI below the cut-in setting. Proper pre-charge ensures the tank functions as a true booster for water pressure.

Frequently Asked Questions
What size booster tank for water pressure do I need?
The size depends on your pump’s flow rate and your household’s peak water usage. A general rule is to choose a tank with a drawdown of at least 1 gallon per 10 GPM of pump flow. Use our sizing guide linked above for precise calculations in 2026.
How does a pressure tank improve water pressure?
A pressure tank stores water under compressed air, so when you open a faucet, the tank releases water at consistent pressure without immediately triggering the pump. This reduces pressure fluctuations and pump cycling. Learn more in our detailed explanation.
Can I install a booster tank myself?
Yes, if you have basic plumbing skills and follow the manufacturer’s instructions. You’ll need to connect the tank to your system using a tee kit and adjust the pre-charge pressure. For complex setups, consider hiring a professional.
How often should I check the pre-charge pressure?
Check the air pressure in your tank every six months to ensure it remains at the correct setting (usually 2 PSI below the pump cut-in). Use a standard tire gauge and a bicycle pump to adjust as needed.
