INSTALLATION & USE
Setting Up Your ROMATE-15 Tank
- Position tank vertically or horizontally as needed for your installation space—the ROMATE-15 discharges reliably in any orientation.
- Connect the pre-installed 1" male NPT inlet-outlet assembly directly to your RO system permeate line and distribution plumbing using PTFE tape or thread sealant.
- Pressurize the tank to 40 PSI for optimal water capacity and flow performance, adjusting air charge through the Schrader valve if necessary.
- Flush the system thoroughly before use to remove any manufacturing residues from the seamless HDPE liner.
COMPATIBILITY
System Applications
The Structural ROMATE-15 tank works with residential and light commercial reverse osmosis systems requiring a 1" NPT connection and mid-range storage capacity. Its 14.5-gallon total volume and 5-8 gallon usable capacity make it ideal for homes, small offices, and light commercial applications where consistent pressurized water delivery is essential. The 100% lead-free construction with NSF and FDA listed materials ensures safe potable water storage that won't leach chemicals or contaminants.
🔧 Pro tip: Check and adjust the air pressure in your ROMATE-15 tank before connecting it to your RO system. The tank should be pressurized to approximately 5-7 PSI below your system's shut-off pressure for optimal water capacity and to prevent premature cycling.
