Buying Guide for a 50 Gallon Pressure Tank
When selecting a pressure tank for your well, several factors determine performance and durability. Here are the key criteria to consider.
Tank Capacity and Drawdown
The total tank volume matters, but what really counts is the drawdown volume the amount of water stored between the pump cut-in and cut-out. A 50 gallon pressure tank typically delivers a drawdown of 10 to 15 gallons depending on the pressure switch setting. For a household with 2 to 4 bathrooms and a kitchen, a 50-gallon tank (or a 52-gallon model like the Reliance) provides ample reserve and minimizes pump cycling. If you have high water demand or multiple fixtures running simultaneously, consider a larger tank. Our well pressure tank sizing can help you match capacity to your household needs.
Material and Liner Quality
Pressure tanks are exposed to constant water pressure and potential corrosion. Look for tanks with a heavy-gauge steel shell and a corrosion-resistant inner liner. Amtrol models use virgin polypropylene liners that will not crack, chip, or peel. VEVOR and Red Lion tanks feature thickened carbon steel and butyl rubber diaphragms. A robust liner prevents water contamination and extends the tank’s life. Avoid tanks with thin steel or poor coatings that can rust over time.
Connection Type and Pre-Charge Pressure
Most residential well pressure tanks use a 1-inch NPT connection. Ensure the tank you choose matches your system’s piping. Pre-charge pressure is factory-set but should be adjusted to 2 PSI below the pump cut-in setting. Tanks like the Red Lion RL34A come pre-charged to 20 PSI and require topping off with a bicycle pump. A proper pre-charge ensures the diaphragm functions correctly and prevents waterlogging.
Certifications and Safety
For drinking water systems, choose a tank certified to NSF/ANSI 61 and 372 standards. The Red Lion RL34A is certified for safe drinking water. Some tanks, like the VEVOR 34-gallon, are explicitly marked as not suitable for potable water. Always verify the tank’s intended use. Additionally, a pressure relief valve (sold separately) is recommended to prevent overpressure damage.
Final Thoughts
Choosing the right 50 gallon pressure tank for your well comes down to balancing capacity, build quality, and your specific water usage. For most households, the Reliance Pressure Tank 52 Gallon Vertical Steel offers the closest match to a 50-gallon requirement with a durable steel shell and butyl diaphragm, making it an excellent choice for consistent pressure and pump protection. If you prefer a proven brand with decades of reliability, the Amtrol WX-202 Well Pressure Tank provides a corrosion-resistant polypropylene liner and a strong steel shell in a compact footprint, ideal for smaller homes or as a secondary tank. Both options deliver the performance you need to keep your well system running smoothly for years.
Frequently Asked Questions
What size pressure tank do I need for a 50 gallon well tank? The pressure tank size depends on your pump’s flow rate and household demand. A 50 gallon pressure tank is suitable for homes with 2 to 4 bathrooms. For larger homes, consider a tank with a higher drawdown volume. Refer to our sizing guide for detailed recommendations.
How long does a 50 gallon pressure tank last? With proper maintenance, a quality tank can last 10 to 15 years. Tanks with butyl diaphragms and corrosion-resistant liners, like those from Amtrol, tend to have longer lifespans. Check the pre-charge pressure annually and replace the air valve if needed.
Can I use a 50 gallon pressure tank for a submersible well pump? Yes, a 50 gallon pressure tank works well with submersible pumps. It reduces short cycling and protects the pump from wear. Ensure the tank’s pre-charge matches your pressure switch settings.
What is the difference between a 50 gallon and 34 gallon pressure tank? The main difference is water storage and drawdown. A 50 gallon tank stores more water, allowing longer periods between pump cycles. A 34 gallon tank is more compact and suitable for smaller homes or lower water usage. Your choice depends on the number of fixtures and daily water consumption.
