In recent decades growing urbanization and industrial development have caused contamination of our natural water supply. Tap water is not safe to drink in most parts of India, as it does not meet BIS standards. According to a report released by Central Water Commission(CWC), water in most of the cities was found polluted and unfit for drinking. Your tap water might contain harmful bacteria such as E.coli or heavy metals. Prolonged usage of such water for drinking purposes can cause illnesses in the longer run. Here comes the RO purifier for the rescue.

Reverse Osmosis or RO eliminates chemical contaminants from water to make it fit for use. When the RO process is combined with UV filtration in a purifier, it can also eliminate all biological pathogens. The marker to determine the purity of water is TDS. TDS particles are ultra-minute salts or compounds that are dissolved in water. TDS particles are not eliminated through the process of simple filtration, hence RO is required. WHO mandated level of TDS for safe drinking water is 300 mg/liter.  

There are a few things to keep in mind before you decide to buy an RO purifier or if you already have one. These are the most common RO problems and solutions in India:

1. Taste and smell of the RO purifier water

If you experience that water filtered from your RO purifier is foul in smell or bad in taste, it means you need to replace the filters. Biofilm is an organic layer of organic and inorganic compounds that accumulate on the filters after long usage. It can cause a rise in the level of contaminants in the purified water.

The solution to this problem is to get the filters replaced. Typically, you need to replace the filters every twelve months for the efficient functioning of the RO purifier.

2. Water flow or pressure

If your RO is releasing water slower than it normally does, it might be because of low water pressure. Mandated minimum pressure for RO purifies is 40-60 PSI ( pounds per square inch). If it is lower than that, you might not be able to operate it properly. It can be because of malfunctioning or leakage in the bladder. To resolve this issue, you would need to replace the clogged filters with the help of RO service providers.

2. Functioning of RO purifier’s faucet

Sometimes you may experience a constant water leakage from the RO purifier’s faucet. This can be because of an ill-fitted O-ring around the faucet. O-ring is a soft rubber ring that prevents leakage of the water and keeps it intact. In this case, you would need to call RO service to either get the O-ring replaced or fixed tightly.

4. RO water tank taking too long to fill up

This is another common problem for the users of RO water purifiers. In this case, the purifier’s tank either doesn’t get filled up at all or fills up too slowly. This is because of unusually low water pressure, i.e, below 40-60 PSI. This can also be caused by a damaged or clogged filter membrane, as discussed above. To ensure proper pressure in the membrane, it needs to be replaced once a year. Alternatively, you might need to get a pump installed if low pressure is because of any other reason.

5. Unusual vibrations and noises in RO Purifier.

RO pump is the most common cause of this problem. The pump ensures the required amount of pressure in the membrane. After constant use over the time, RO pump can become noisy. It is because one of its parts, bearings, vibrate at a very high speed to maintain a constant amount of pressure. These vibrations and friction can cause wear and tear in other parts of the RO purifier as well. To resolve this issue, you need to call the RO service provider to identify the exact problem and resolve it for you. Typically they might need to replace the RO pump if it has been a long time since the last servicing.

6.Wastewater volume is in excess

This common issue again causes clogged or damaged membranes in the filter. The rejected water from the RO purifier contains a high amount of TDS and contaminants. This forms an integral part of the functioning of a RO water purifier. The solution to this problem is regular maintenance and service of the RO purifier. In this case, also, you would need to get the filter membrane replaced for the efficient functioning of the RO water purifier.
