Buying Guide: Choosing the Right Pressure Tank for Your Water Pump
Tank Capacity and Drawdown
The size of your pressure tank directly affects how often your pump runs. A larger tank provides more drawdown (usable water) between pump cycles, reducing wear. For a typical home well, a 20-gallon tank like the Reliance Pressure Tank – Pre-Charged offers a good balance. For small spaces or RVs, a compact 2-gallon unit like the SEAFLO 2 Gallon Pre-Pressurized Accumulator works well. Check our well pressure tank sizing for detailed recommendations.

Pressure tanks are typically made of steel or stainless steel. Steel tanks are economical but can rust if not properly coated. The Amtrol WX-202 Well Pressure Tank features a high-strength steel shell with a virgin polypropylene liner that won’t crack or peel, offering excellent corrosion resistance. For outdoor or marine use, stainless steel models like the Aquastrong or VEVOR pumps provide added protection.
Pressure Rating and Pre-Charge
Your tank must match your pump’s pressure switch settings. Most tanks come pre-charged to a specific PSI (often 20 PSI) and can be adjusted with a bicycle pump. The Red Lion RL4A In-line Pre-Charged Well Pressure tank is pre-charged to 20 PSI and works with standard 30/50 or 40/60 PSI systems. Always verify compatibility before purchase.
Installation Type and Space
Consider whether you need a vertical or horizontal tank, and whether it will be mounted inline or free-standing. The Reliance Pressure Tank 20 Gallon Horizontal is ideal for tight spaces like basements or crawlspaces.

Frequently Asked Questions
How does a pressure tank work with a water pump?
A pressure tank stores water under compressed air. When you open a faucet, the tank’s air pressure pushes water out, reducing the need for the pump to turn on. Once the pressure drops to a set point, the pump refills the tank. This cycle reduces pump starts and extends pump life. For a deeper explanation, our guide on well pressure tanks covers the details.
What size pressure tank do I need?
The right size depends on your pump’s flow rate and your household water usage. A general rule is to select a tank that provides at least 1 gallon of drawdown per 5 GPM of pump flow. For most homes, a 20- to 30-gallon tank is sufficient. For smaller systems like RVs, a 2- to 4-gallon tank works well. Use our sizing guide for precise calculations.
Can I install a pressure tank myself?
Yes, many pressure tanks are designed for DIY installation. The key steps include connecting the tank to your plumbing using a tee fitting, setting the pre-charge pressure to 2 PSI below the pump cut-in pressure, and securing the tank to prevent movement. Always follow the manufacturer’s instructions. The Red Lion RL4A and SEAFLO 2 Gallon tanks are both user-friendly for installation.
How long does a pressure tank last?
With proper maintenance, a quality pressure tank can last 10 to 15 years. The tank’s diaphragm or bladder is the most common part to fail. Brands like Amtrol and Reliance use durable butyl rubber diaphragms that resist cracking. Checking the air pre-charge annually and ensuring the tank is not waterlogged can extend its lifespan. Models like the Amtrol WX-202 are built to last with corrosion-resistant liners.
