Common RO Purifier Problems & Quick Fixes You Can Try

Netsol Water is the leading RO Plant Manufacturer, and we handle many service calls each month. People trust our name because we design durable plants and support installation and maintenance across many sites. Homeowners and small businesses need to understand why an RO may stop working well and what steps to take before calling a technician. The goal is to save time and prevent needless service charges while making sure water stays safe to drink.

Common RO Purifier Problems

Let us have a look on some common problems.

Low Water Flow from Tap

Low water flow often means the system works, but it cannot push enough water through the membrane. A clogged pre-filter or a fouled membrane will reduce output. Many systems use sediment and carbon filters that trap dirt and chlorine. These filters block flow after a number of months. Users who skip the routine filter change will see slow output and longer fill times for the storage tank. Low input pressure can also lower flow. A weak household pump or low municipal pressure will limit the membrane performance. Check the pressure gauge when your RO has one. The gauge will tell you if the pressure drops below the recommended level. If the gauge shows low pressure, then the pump or feed source needs attention. If the pressure reads normal, then the filters or the membrane likely need service.

Bad Taste or Odour in Water

Bad taste or odour usually means the system no longer removes dissolved impurities, or the storage tank keeps stale water. Carbon filters remove smell and taste elements early in the train. When these filters age, they lose their ability to absorb organic compounds. The result is water that smells like chlorine or has an off taste. Biological growth in the tank can also cause a smell when the tank stays full and the system sees little use. Regular tank cleaning and timely filter replacement prevent this outcome. If the system uses a UV lamp, then low lamp output will not kill bacteria, and this may affect the smell. Measure total dissolved solids to see if the membrane still rejects salts. If TDS rises, then the membrane may have failed. A certified RO Plant Manufacturer will check filter condition and tank hygiene and will advise if the membrane or UV lamp needs change. Simple actions like flushing the system and changing carbon filters often bring back good taste without a service call.

Quick Fixes You Can Try

Let us have a look on some fixes and how to do them in order.

Check and Replace Pre Filters

Pre-filters protect the membrane, and they need regular replacement to keep the plant healthy. The filters trap sediment and chlorine and they stop the membrane from fouling fast. If you see low flow or bad taste, then check these filters first. Turn off the feed and relieve pressure before you open any housings. Remove the old cartridge and look for heavy dirt or staining. A dark cartridge means it has reached the end of its useful life. Replace the cartridge and then run water through the system to flush any trapped debris. This step may restore flow and taste quickly. Keep a simple schedule and mark the date when you change filters. This habit will prevent many common faults and extend the life of the membrane.

Fix Leak and Pressure Issues

Leaks and incorrect pressure cause many faults that seem more complex than they are. A loose connection or a worn valve will cause poor tank fill or no water at the tap. Start by checking all visible fittings and hoses for wetness or pools of water. Tighten fittings by hand and avoid over-tightening plastic parts. If the feed pressure is low then a booster pump may help restore normal operation. If pressure spikes happen, then a pressure regulator will protect the membrane and valves.
