When you buy a premium RO water purifier, you expect it to provide safe, sweet-tasting drinking water for years. But just like a car, your water purifier requires regular care to keep its engine (the RO membrane) running smoothly.
Skipping maintenance doesn’t just lead to bad-tasting water; it can cause major internal damage that costs thousands of rupees to fix.

Here are 5 simple maintenance tips to easily double the lifespan of your RO machine.

1. Change the Pre-Filter Every 3 to 6 Months
The pre-filter is the white, sponge-like candle outside your main RO unit. It acts as the first line of defense, trapping heavy mud, sand, and rust. Because water quality varies across Indian cities, this filter gets choked quickly. Replacing it on time takes the pressure off the internal RO membrane, increasing the membrane’s lifespan by up to 50%.

2. Watch Out for Drips and Leaks
A small drip from your RO machine might not seem like a big deal, but it is a warning sign. Ignoring minor leaks can cause water to enter the electrical components (like the SMPS adaptor or pump), causing a short circuit and leading to expensive repairs. If you see a leak, get it checked immediately.

3. Monitor the Reject Water Flow
Always keep an eye on the waste water pipe. If the reject water stops flowing completely, it means your membrane is blocked. If water flows continuously even when the tank is full, your Auto Shut-Off Valve has failed. Both situations require professional attention.

4. Sanitize the Storage Tank Annually
Even though the water inside the RO tank is purified, keeping water stored in a closed plastic tank for months can lead to a slimy buildup. Have a professional technician empty, clean, and sanitize the internal storage tank at least once a year to ensure your water stays fresh.

5. Don’t Ignore the “Filter Change” Alarm
Modern purifiers from brands like Kent, Aquaguard, and Pureit come with filter-change alarms. Do not simply switch off the alarm or ignore it. Running the machine beyond its filter life forces impurities directly into your drinking water.
