Water Purifier Maintenance: Checklists and Guidance

Table of Contents

A water purifier is an essential device in your home, especially if you are living in a country like India, where the water quality varies from one place to another.

It is important that you maintain your water purifier properly so that it serves you for a longer period & also ensures that you & your family get pure & healthy water to drink.

Just like every other equipment, a water purifier too needs some maintenance so that it functions efficiently. Neglecting the upkeep of your water purifier can be hazardous for your health.

Understanding the importance of regular maintenance

A water purifier works by removing harmful substances from the water, like heavy metals, harmful salts, bacteria and many other impurities. This is done by passing water through a series of filters.

Over time these filters get blocked due to the accumulation of all the harmful substances that they are supposed to remove. A blocked filter cannot function properly & can even become a breeding place for bacteria.

Hence, it becomes all the more important to ensure regular maintenance of your water purifier so that you get healthy water all the time.

What are the core components of your purifier?

One can’t just blindly go on servicing their water purifiers without knowing the important parts of the water purifier.

Knowledge about different components will help you in better understanding and handling of your water purifier. Even though there are different types of water purifiers available in the market yet most of the water purifiers use multiple stages of purification.

Sediment Filter: Removes visible dirt and dust.
Carbon Filter: Eliminates chlorine and organic chemicals.
RO Membrane: Reduces Total Dissolved Solids (TDS levels).
UV Lamp: Kills bacteria and viruses.
UF Membrane: Removes additional cysts and germs.

After you have learnt about the different parts of your water purifier, it becomes easier for you to take care of your water purifier. Depending on what is wrong with your water purifier, you will be able to identify which part of your water purifier needs attention.

The Comprehensive Maintenance Checklist

What should you do and when? Below is a list of routines that keep the water purifier functioning.

#1. Daily and Weekly Maintenance Routine

It only requires a quick look. In a few minutes, these duties can avert much leakage.

Check the inlet plus outlet tubes. See if there is any water that is gathering around the unit. Such leaks are mostly due to loosely fitting connectors. Turn round gently to make sure they are tight.
Watch how fast water is coming out. If there is a sudden decrease in flow rate, then there is a probable blocking hazard. It implies that the sediment filter should be changed.
Use a piece of cloth to wipe the outside part of the water cleaner. Hygiene and aesthetics may be affected due to dust accumulation. Make sure that the area surrounding the purifier remains dry.
It produces some kind of noise while working. Still, very loud humming or shrieking is not right. Most times this indicates a weak pump or low water pressure.

#2. Monthly Maintenance Tasks

Monthly checks are slightly more technical. They focus on the pre-filtration stages.

Among all, the sediment filter and pre-activated carbon filter are most vulnerable. For instance, in areas where the municipal water contains elevated levels of chlorine, this filter may wear out quickly. Check if the water is cloudy or if it has some peculiar smell.
In case the water tastes flat or salty, then there could be a need for adjusting the TDS controller or the failure of the RO membrane.
People always touch the dispenser tap; hence, it may contain bacteria. Use some disinfectant to clean it thoroughly.
An RO system discards impurity-laden water. Be certain that the wastewater pipe is flowing without any problem. If blocked, this could cause harm to the pump.

#3. Quarterly and Bi-annual Maintenance

During this stage, you will usually have to replace some filters.

Generally, it is recommended that the sediment and carbon filter be replaced every six to twelve months. Nevertheless, it is advisable to change them every three to four months in case you have a dirty sediment filter that chokes up the RO membrane if the water is hard or has a lot of suspended particles.
Ultraviolet light is employed by the UV lamp in purifying water. Even though the bulb has a long life, its strength decreases with time. It is common to carry out an annual check for efficient removal of microbes.
The booster pump keeps the water pressure steady. A technician should check the output pressure because low pressure slows down the purifier’s recovery rate.

#4. Annual Maintenance

Among all other costs, this one appears to be the most important for water purifier maintenance.

At a price, the RO membrane is very expensive. It has an average life span of 2-3 years; nonetheless, this may be reduced by high TDS in the feed water. Change the membrane as soon as you see that the TDS meter indicates high readings in the purified water.
An extensive cleaning of the interior storage tank. Where moisture is present, there may be growth of biofilm or algae. Toxins will be removed from the water through tank cleanup.
The professionals have to use some special grade of food sector chemicals for washing pipes and filters. This helps in getting rid of stubborn scale as well as bio-sludge.

How to Recognize That Servicing Is Urgent

Forget about what date it is on the calendar. Look for the below red flags. They mean your water purifier requires immediate repairs.

#1. Different Flavors or Smells in Water

Normally, pure water has no taste or smell.

Damaged RO membrane is indicated by a salty taste. It allows the passage of salt.
An exhausted carbon filter will not be able to absorb chlorine or volatile organic compounds, hence producing a chemical smell.
Earthiness: Most times, this shows that there are bacteria growing in the tank.

#2. Slow Water Flow

Many people say they now don’t get water as fast as they used to when pressing the dispenser button. Some causes are:

Blocked sediment filters
Dirty RO membrane
Air blocks in pipes
Inadequate supply line pressure—If the input pressure falls below the recommended level (typically 15-20 psi), you may need to install a booster pump.

#3. Problems with Leakage

Leaks are capable of destroying the floor and cupboard.

Examine the O-rings and seals located inside the filter housings.
Make sure that the waste pipe is not bent or twisted.
Check if there are any fractures on the storage tank.

#4. Failure to Automatically Turn Off

When the tank is full, the purifier must stop by itself.

Continued running will lead to water spilling out. It usually occurs when there is a problem with either the float valve or the auto-shut-off valve.

DIY vs. Professional Service

Water purifiers are among the items that many homeowners attempt to decide if they ought to carry out the maintenance by themselves or employ the services of professionals. This leads us to the question: what parts of water purifiers can be easily maintained at home and which ones require specialized knowledge?

Maintenance You Can Perform

Washing from the outside.
Searching for leakage.
Adjusting the accessible TDS control valve.
Resetting the filter alarm (in case of changing the filter).

Maintenance that requires professional technicians

Opening filter housings
Replacing RO membrane or UV lamp
Cleaning inside tanks
Fixing electrical faults or pump problems

It is advisable to hire an authorized service center because they have better skills and knowledge. Such professionals use original parts.

Understanding the Costs: AMC vs. Pay-Per-Service

#1. Annual Maintenance Contracts (AMC)

AMC for water purifier is a complete package.

Pros: This package consists of periodical visits, changing of filters, or any other kind of general service included inside. In case of anything, one is at rest. AMC helps in spreading costs throughout the year. Additional benefits are also available in most cases.

Cons: It may appear costlier at first.

Recommendation: AMC is the best option for people who are new owners. It keeps the warranty safe and ensures that there is professional servicing available.

#2. Pay-Per-Service

The second alternative is pay-per-service, which means you will only pay when you use it.

Pros: You do not need to pay for a monthly charge.

Cons: The cost could become very high if many of the components fail simultaneously.

Recommendation: This is advisable for those who do not use a lot of water or have some technical knowledge.

Step-by-step procedure on how to sanitize your storage tank

Although most people prefer leaving it to be done by a professional, there are some things that you can do alone, like cleaning the tank. It is important that you know how to take care of this.

Turn off the main power supply.
Unplug the cord.
Drain all the water from the storage tank via the faucet.
After that, mix a mild disinfectant or food-grade sanitizer with water. Remember not to use bleach or strong chemicals.
Scrub gently. Use a soft sponge or cloth to scrub the inner walls of the tank.
Rinse thoroughly. Ensure no chemical smell remains after rinsing the tank several times with clean water.
Lastly, turn on the inlet water supply. Let the tank fill. Discard the first two batches of water to ensure safety.

Common Mistakes to Avoid

Many first-time purchasers make certain mistakes that nullify the guarantee or harm the machine.

Never reset indicators without replacing the filters in modern purifiers. Using
Be sure to always use branded filters. Note that generic ones might not properly fit or could even be toxic with the water.
In case of an extended holiday, for example, remember to turn off both the water tap and electricity switch. After returning, run the purifier for 10 minutes and discard the water coming out of it. This helps get rid of stale water.
Ensure that you clean the drip tray often. Stagnant water in the tray attracts insects and promotes mold.

Conclusions

The water purifier maintenance checklist is compulsory to live healthily. In India, water contamination poses a high risk; therefore, your purifier serves as protection. If you adhere to this service manual for water purifiers, then you will be sure that it works well. You have to change the filters often, change the membranes as soon as they are due, and clean the tanks from time to time; these are all essential.
