Certainly! To determine if your ProTool RO Membrane 4040 Ultra Low Pressure is failing, check for a significant drop in water quality—anything less than an 80% TDS reduction means poor performance, while above 90% efficiency is ideal. If you notice lower water pressure, slower filling times, or reduced purity, your 4040 reverse osmosis membrane may need replacement. Also, ensure your 4040 RO membrane housing is properly maintained, as issues there can affect the xlp 4040 membrane's performance.
