For optimal performance, maintain a tank pre-charge of approximately 7 psi. The TPG-917B Tank Pressure Gauge (0–20 psi) provides more accurate readings at this low pressure than most automotive tire gauges.
The tank should be sanitized before initial use and during routine filter changes. The Reverse Osmosis Sanitizing Maintenance Kit, featuring Sani-System sanitizer and an application syringe, provides a convenient alternative to chlorine bleach for sanitizing the tank and RO system.
