Description
Is your RO system slow to fill or losing pressure? The PA-E RO-152 is the industry standard for 6-gallon reverse osmosis storage. While it holds a 5.5-gallon total volume, it provides the consistent water pressure you need for your kitchen faucet or ice maker.
Why Choose Reverse Osmosis Water Storage Pressure Tank?
Unlike cheaper alternatives, this tank uses a high-grade chlorobutyl diaphragm and a stainless steel water connection. This means no rust, no leaks, and no metallic aftertaste. It’s designed to keep your purified water as clean as the moment it left the filters.
- Safety First: Constructed with 100% FDA-approved, food-grade materials.
- Durable Build: The deep-draw steel dome and precision-welded seams are built to last for years.
- Universal Fit: Standard 1/4″ MPT connection works with almost all residential RO brands.
Installation Guide: 3 Steps to Fresh Water
Connect & Set: Screw the tank valve onto the stainless steel nipple and plug in your 1/4″ tubing.
Flush the System: Fill the tank once, then drain it completely to rinse the internal liner before drinking.
Frequently Asked Questions
Q: Will this tank work with my existing RO system?
A: Yes. This is a universal storage tank. As long as your system uses standard 1/4″ tubing, the included valve and 1/4″ MPT connection will fit almost all residential brands like APEC, iSpring, Express Water, and Home Master.
Q: Why is it called a 6-gallon tank if it only holds 5.5 gallons?
A: In the water industry, “6 Gallon” refers to the total internal volume of the steel shell. However, because the tank contains an internal air bladder to push the water out, the actual water storage capacity is approximately 5.5 gallons.
Q: Does this tank come pre-pressurized?
A: Yes. We ship these tanks pre-charged with 5 to 7 PSI of air pressure. It is ready to be installed right out of the box. We recommend checking the pressure with a standard tire gauge once a year to ensure peak performance.
Q: How often should I replace my RO storage tank?
A: Most high-quality tanks like the PA-E RO-152 last between 5 to 7 years. If your faucet is only giving you a small amount of water before the flow slows to a trickle—and your filters are new—it’s likely time to replace the tank.
