A reverse osmosis membrane is the powerhouse of your water purification setup. While pre-filters protect it, natural fouling and mineral buildup will eventually degrade its efficiency over 24 to 36 months.
Warning Signs You Should Not Ignore
Keep an eye on these typical performance indicators to avoid drinking sub-par water or straining your booster pump:
- Creeping TDS readings: If your purified water TDS exceeds 20% of your raw feed water.
- Slow tank fill times: Noticeably reduced flow rate from your dedicated drinking tap.
- Continual drain wastewater flow: The auto-shutoff valve fails to seat due to low permeate pressure.
- Noticeable taste and clarity alterations.
Scheduled Preventive Maintenance
Replacing sediment and carbon pre-filters every 6 months prevents chlorine degradation of thin-film membranes, ensuring the core RO element lasts its full 3-year design life.
