R-1070-14 14-Gallon Reverse Osmosis Steel Bladder Tank, White

RO-1070-1/4-WH can be used as a replacement part, upgrade, or additional tank for any reverse osmosis system. The tank includes a 1″ connection, supplied with a reducer and ball valve, to accept 3/8″ tubing. This 14-gallon RO tank can sit on a stand with a connection port on the top or bottom.

Model number: RO-1070-14-WH

Tank capacity: 14-gallon (storage tank size)

What is the 14-Gallon Reverse Osmosis Steel Bladder Tank Used For?

• Reverse osmosis drinking water systems that require pressurized storage
• Higher-demand kitchens, break rooms, and light commercial use where more stored RO water is needed
• Upgrades from smaller RO tanks to increase available draw volume and reduce waiting between fills
• Replacement for a tank with a ruptured bladder, loss of pressure, or poor delivery

Compatibility Checks for the RO-1070-14-WH
Before ordering, confirm:

• Your system uses a standard pressurized RO storage tank (not a tankless RO-only configuration)
• Your available space can accommodate a 14-gallon tank footprint and height
• Your tubing and fittings match the tank connection type and size used in your RO setup
• Your RO system can support the added storage volume (larger tanks take longer to refill)

Common Compatible Use Cases

• Most standard under-sink RO systems that use a storage tank and tank shutoff valve
• Applications where a higher stored volume is needed for cooking, beverages, ice, or multiple users

What’s included

• (1) 14-gallon steel bladder storage tank (RO-1070-14-WH)
  Tank shutoff valve, tubing, and fittings are not included unless explicitly stated on the product page.

Installation Guidance for the RO-1070-14-WH

Install difficulty: moderate

Simple concept, but correct connections and air precharge setup matter for performance.

1. Shut off the RO feed water and close the tank valve on the existing tank (if installed).
2. Depressurize by opening the RO faucet until the flow stops.
3. Disconnect the existing tank from the tank line and remove it.
4. Place the new tank on a level surface where it can be serviced.
5. Verify the tank air precharge matches your RO system requirements before connecting.
6. Install or transfer the tank shutoff valve if required by your setup.
7. Reconnect the tank line, open the tank valve, then restore RO feed water.
8. Allow the system to fill fully, then flush the first full tank if required by your RO instructions.
9. Check all connections for leaks and recheck later the same day.

Use cases

• Increasing available RO water volume for larger households or higher daily demand
• Improving draw performance when a smaller tank is not meeting usage needs
• Replacing an older tank that no longer holds pressure or delivers consistent flow

Replacement Triggers
Replace the tank if you notice:

• Reduced RO faucet flow even after filter changes
• Tank feels heavy but delivers little water (bladder failure symptoms)
• Tank will not hold pressure or air charge
• Refill behavior becomes erratic, or the tank no longer provides a consistent draw

Maintenance Schedule

• Check for leaks at fittings during routine RO filter changes
• Verify performance periodically by confirming normal draw and refill behavior
• If you service your RO annually, include a quick tank inspection and connection check

Common Questions on a 14-Gallon Reverse Osmosis Steel Bladder Tank

Q: What does a bladder tank do in an RO system?
A: It stores purified water under pressure so you have water available on demand at the RO faucet.

Q: Is a 14-gallon tank too large for under-sink use?
A: It depends on your space. Measure the clearance and footprint before ordering, as larger tanks require more space.

Q: Will a bigger tank give me higher faucet flow?
A: It can improve delivery during draw because stored water is pressurized, but refill time will be longer due to the larger capacity.

Q: How do I know if my RO tank bladder is failing?
A: Common signs include very low faucet flow, inconsistent delivery, or a tank that seems heavy but delivers little water.

Q: Do I need to adjust the air pressure in the tank?
A: Many RO tanks require a specific precharge range for best performance. Verify your system’s recommended tank precharge before installation.

Q: Will this work with any RO system?
A: It works with many RO systems that use standard pressurized storage tanks, but you must match connection type, space, and system requirements.

Q: Do I need a new tank shutoff valve?
A: Use the valve required for your setup. Some installations reuse the existing valve if compatible, while others replace it during the swap.

Upgrade or replace your RO storage tank with the RO-1070-14-WH 14-gallon steel bladder tank for more stored water and stronger on-demand delivery at the faucet.
