Ideal System Applications
- Residential well water systems require consistent pressure.
- Commercial water storage and pressure regulation.
- Pressure booster pump applications for low-flow scenarios.
- Large-scale reverse osmosis systems (requires pre-charge adjustment).
- Lawn and garden irrigation systems.
- Cottage or seasonal property water systems.
Common Pressure System Problems
If You're Experiencing:
- Well Rite pressure tank is cycling on and off too rapidly (short-cycling).
- Fluctuating water pressure when multiple faucets are open.
- Pump overheating due to frequent starts.
- Water hammer or banging noises in pipes.
- Corrosion or rust on your existing steel tank.
The Well-Rite WR-120R Well Pressure Storage Tank Steel uses CAD-2 technology to maximize drawdown and reduce pump cycles, significantly extending the life of your pump while delivering steady water flow.
Key Benefits of this Well Rite Pressure Tank
- Heavy-duty 16-gauge steel construction ensures durability in harsh environments.
- An anti-microbial liner maintains cleaner water storage and hygiene.
- Stainless steel connections resist corrosion better than mild steel alternatives.
- Efficient drawdown reduces energy consumption by limiting pump starts.
- Suitable for both indoor and outdoor installation due to appliance-quality paint.
Installation & Maintenance
- Pre-charged to 38 PSI; adjust air pressure to 2 PSI below your pump's cut-in pressure (e.g., 28 PSI for a 30/50 switch).
- For reverse osmosis systems, reduce pre-charge to approximately 7 PSI.
- Compatible with standard 1" tee kits and pressure tank installation kit components.
Maintenance Guidelines:
- Check internal air pressure annually to ensure proper system operation.
- Visually inspect the tank exterior for any signs of damage or corrosion.
- Ensure the air valve cap is securely tightened to prevent air loss.
Accessories & Add-Ons
To complete your installation, consider pairing this 33-gallon well pressure tank with a compatible tank tee kit. We also recommend checking your pressure pumps to ensure they match the tank's capacity.

Frequently Asked Questions
Can I use this as a 33-gallon well pressure tank replacement?
Yes, the WR-120R is a direct replacement for most standard 33 or 32-gallon pressure tanks. It offers a 33.4-gallon volume and standard 1" connections for easy swapping.
Is this tank suitable for Reverse Osmosis?
Yes. While it ships pre-charged for well applications (38 PSI), the Well-Rite WR-120R Well Pressure Tank works excellently for RO applications when the pre-charge is lowered to 7 PSI.
Where is the Well-Rite tank manufactured?
Flexcon Industries manufacture these tanks in the USA, ensuring high quality and compliance with North American standards like NSF 61.
How often should I check the air pressure?
You should check the pre-charge pressure annually. The tank must be completely empty of water when checking the air pressure to get an accurate reading.
Does the tank come with a warranty?
Yes, the well-rite 33-gallon pressure tank comes with a 5-year limited warranty from the manufacturer, covering defects in materials and workmanship.
What is the difference between the WR120 and WR120R?
The model numbers are often used interchangeably. The "R" typically denotes the standard residential retail version of the Well Rite wr120r, which includes the same 33.4-gallon capacity and specifications.
