Performance and operating guidelines

Under typical conditions, the membrane delivers up to 75 gallons per day at 60 psi, with a 1:2 pure water to waste ratio. For best results, operate within moderate feed water conditions and avoid freezing. A short flush before first use helps remove loose manufacturing residues.

• Flow rate: 75 GPD at 60 psi
• Waste to pure water ratio: 1:2
• Feed water: 40–100 psi, 40–110°F, pH 3.0–11.0, free chlorine <0.1 ppm, max TDS ~1000 ppm

Lifespan, care, and use

Expect a lifespan of around 24 months or up to 35,000 gallons for typical tap water (200–500 ppm), depending on usage and water quality. Do not freeze and remember to flush the new membrane for about 30 minutes before heavy use. Regular maintenance and proper storage help sustain performance over time.

• Lifespan: up to 24 months or ~35,000 gallons (typical tap water)
• Flush new membrane for 30 minutes before first use
• Do not freeze; avoid hot water in the system
