RO Water Purifier Maintenance Cost, AMC & Tips | All Brands

An RO water purifier is a machine that requires regular maintenance to keep it functioning efficiently. The machine parts, like valves, pressure pumps, etc., are usually under warranty. However, they last longer and do not require recurring maintenance.

The RO membranes and other filters require frequent replacement because the filters can get clogged with impurities and become ineffective. Much depends on the water quality. The higher the contamination, the more frequently will the filter membranes require a change. 

Usually, all RO water purifiers offer UV treatment. UV lamps do not need frequent replacing, but no one can guarantee how long they will last.

Maintenance and Tips for Effective functioning of RO water purifier

RO water purifiers are expensive and require proper care to last long. But the good news is that these appliances can last more than ten to fifteen years if maintained properly. So, let us discuss some maintenance tips for the effective functioning of the RO water purifier.

1. Follow the User Manual

Every RO water purifier has a user manual listing the machine’s specifications, installation instructions, working details, maintenance tips, dos and don’ts, and customer service center numbers.

Reading and understanding the user manual helps because it enables you to use the machine properly and take care of minor repairs at home without booking a service visit. Unfortunately, each visit by a qualified service engineer costs money.

The manual provides the details of the frequency of replacing the water purifier’s RO membranes and other filters and cartridges. While the water source quality determines the lifespan of the filters, it is better to go by the rule book. However, if you notice a change in the water quality, it is better to replace the cartridges.

2. Keep a TDS meter handy.

TDS Meter

It is advisable to note down the TDS levels of RO-purified water as soon as you install the water purifier. It is better to purchase a TDS meter and monitor the TDS levels weekly or at least fortnightly. It enables you to understand whether the water quality has deteriorated or not.

How To Test TDS in Water

If you find any abnormal change in the water quality, you must investigate the matter by escalating it to the service engineer. Usually, cleaning the sediment filters, the water tank, and other filters should resolve the problem. However, if it remains unresolved, you must consider replacing the cartridges.

3. Know the filters and cartridges maintenance schedule.

The user manual details the filter replacement schedules. You must note it down and refer to it whenever you observe a change in the water quality. However, you must also know that a difference in the water quality does not always necessitate changing the filters. Cleaning them can also help resolve the issue.

Usually, the sediment and UF filters get choked with impurities and contaminants. Therefore, it is better to clean these filters regularly because clogged filters can lead to excess electricity consumption. Besides, it affects your machine’s water purification performance.

Secondly, RO water purifiers have a reputation for wasting water. Clogged filters can result in wasting more water than usual. So, properly monitoring water wastage can also help understand that it is time to clean or replace the filters.

4. Note the filter change alerts.

The latest RO water purifiers feature filter change alerts. So, it reduces your monitoring work considerably because the machine alerts you that it is time to replace the filters.

However, for RO water purifiers not featuring filter change alerts, you must note down the standard replacement schedule.

  1. Pre-filters – six months
  2. Sediment filters – around 12 months
  3. Carbon filters (Pre and Post-RO) – about 12 months
  4. RO membrane – 24 to 36 months

However, much depends on the water source quality. If the TDS levels are high, the RO membrane might require replacement before the standard 24-month period. It also depends on the water usage.

The regular replacement schedules are formulated assuming an average Indian household of four to six members. If there are more users or the use is substantially high, the filters might require replacement earlier.

Therefore, a TDS meter can prove helpful in checking the TDS levels regularly.

5. Clean the water tanks and pipes regularly.

Usually, RO water purifiers have plastic water tanks and pipes. Constant contact with water can lead to microbial contamination in the plastic pipes and tanks, leading to a foul smell.

Therefore, cleaning the water tanks and pipes is crucial at regular intervals. Generally, the RO technician cleans them during the AMC visits or when replacing the filters.

But, users can open the water purifier and clean the tanks themselves. However, cleaning the pipes would require professional help from the service technician. Therefore, booking a service request every six months is advisable for cleaning the tanks and pipes.

6. Check the pipes for leakages.

Any leakage in the pipes can cause water wastage. Therefore, you must summon a service technician to attend to leakages inside the water purifier.

7. Take an AMC.

An AMC can prove helpful in maintaining a water purifier because the contract includes at least two free service visits. The service technician checks the connections for leakages and other issues. He also cleans the filters and removes the blockages. Filter and cartridge replacements can also happen if the situation demands it.

The AMC does not cost much. Generally, the AMC includes all filter and cartridge replacements. Under such circumstances, the AMC is cheaper than replacing the filters individually.

8. Insist on original filter replacements.

Local RO water purifier technicians usually replace the original RO membranes with cheap quality products. These products are initially affordable but do not last as long as the original membranes. Therefore, you must insist on using the original RO membrane and other filters/cartridges when replacing them.

9. Keep the water purifier exteriors clean.

While the AMC and the service technician replace the filters and RO membranes, keeping the exteriors clean is in your hands. So, clean your RO water purifier’s surfaces with a clean cloth every week. It helps maintain these machines for extended periods.

The areas around the dispensing tap can attract mold and other bacteria. So, you must pay more attention to these areas to ensure your family gets clean and hygienic water.

10. Invest in reputed brands.

Cheap quality RO water purifiers are available on the market. However, they do not last long. On the other hand, the models from reputed brands have features like extended warranties and AMCs. Therefore, you can trust these brands to last long.

Remember that your family’s health is critical. So, follow these ten maintenance tips and ensure that your RO water purifier lasts ten to fifteen years.
