After the RO Filter T33 Filter, ALK Filter, and UV power filtration, the water will become clear water for drinking, and the wastewater will flow out through the other end. Determine the way to change the filter When the tap water temperature and pressure are normal (generally 40-104℉, 15 - 70 PSI) 1. When the flow of clear water is less than 0.5L/min, the filter cartridges need to be replaced (It is normal for the flow rate in summer to be slightly higher than the flow rate in winter) 2. Check the value of the water pressure gauge through the RO filter before the pressure detection (generally normal in the 60-110PSI or so), if more than 130psi, and the wastewater valve is not blocked, then you need to replace the RO Filter, followed by the T33 Filter. If the tap water pressure is 40psi, but the water pressure gauge shows much lower than 40psi, you need to replace the PP Filter, followed by the CTO Filter. Recommendation The T33 filter is suitable for T1-400UV, the ALK filter is suitable for T1-400ALK， and the RO/CTO/PP Filter suitable for T1-400 series, including both T1-400UV and T1-400ALK. Replace the PP filter, CTO filter, ALK Filter, and T33 filter every 3-6 months, Replace the RO membrane every 12 months. The actual service life of the filter element depends on the amount of water consumption and quality. Review: As advertised - They work as they should.
