5 Most Common Water Purifier Problems And Solutions

If a water purifier is maintained properly, it can work for 4 to 5 years without any trouble. After that, you may begin to face some common water purifier problems. Water leakage is not the only common water purifier problem that is faced by people. There are various other issues that can arise after a few years of water purifier usage, including unusual taste, unusual smell, noisy faucet, and slow water output. In this article, we have listed the 5 most common water purifier problems and their solutions so that you can easily identify the problem and get it fixed.


5 Most Common Water Purifier Problems And Their Solutions

RO and UV water purifiers are the most commonly found water purifiers in most homes, and each of them can have several issues. However, we have created a list of the 5 most common water purifier problems and tried to list their typical solutions.

1. Unusual Water Taste Or Smell From The Water Purifier

Unusual Water Taste Or Smell width=

If your RO or UV water purifier is offering water with an unusual smell or taste, it could be because a biofilm has accumulated in one or more parts of the water purifier. A biofilm is a layer of organic and inorganic material collected on the surface of a water purifier. Due to this, the levels of contaminants in the water rise. The quickest solution for this is to replace any clogged filters or the membrane. Once the filters and the membrane are changed, you can check if there is an improvement in the taste or odour of the water. Ensure that the filters are changed every 12 months.

RO purifiers use copper tubing in their mechanism. If you notice that the water has a metallic taste, it means the water may have dissolved a high amount of sulfate, chloride, and bicarbonates from the copper tubing, leaving a metallic taste in the water. Similarly, if you find the water from the purifier to be slightly salty, it means the salt and other solids have dissolved in the water. The RO water purifier needs to be fully functional to eliminate these particles from the water. If the water from your purifier tastes saltier than usual, you should call a professional for a maintenance check and get the purifier cleaned. You should carry out this procedure once every 6 months.

2. Slow Water Flow From The Water Purifier

Slow Water Flow width=

If your water purifier is releasing purified water very slowly and fills just half the glass during the same time, it is because you either have low volume or low water pressure. An RO typically needs a minimum pressure of 40 to 60 PSI (pounds per square inch) to operate properly. There could also be a malfunction in the water storage tank of the purifier, leading to this issue. The purifier’s water storage tank contains an air bladder so that it releases water quickly. The more the water, the higher the pressure.

If there is leakage in the bladder, it may not offer enough release pressure and that leads to slow water flow from the water purifier’s faucet. It is also possible that the water filter’s cartridges have been clogged due to high sediment content, which could lead to slow water output. If the filters are clogged, get them replaced by a water purifier service professional.

3. Water Purifier’s Faucet Is Making Unusual Noises

Noisy Faucet width=

If you hear a strange noise from your water purifier’s faucet, especially after replacing the filters and the membrane, it is due to the air being pushed out of the system. It could also be due to a change in the water pressure within the system. Soon after replacing the filter, if the noise doesn’t subside, call a professional to check if the tubing was properly installed. The noise could also occur if the water tank’s valve is not closed properly.

4. Water Is Leaking From The Purifier’s Faucet Or Filter/Membrane

Leaking Faucet Or Filter/Membrane width=

If there is constant water leakage from the purifier’s faucet, a part of the purifier is probably not fitted correctly. To fix the issue, the ill-fitted part needs to be identified and replaced or fitted tightly. If the same issue is found in the water purifier’s filter or membrane, it could be due to a worn-out O-ring. An O-ring is a soft rubber ring that stops water from leaking out of the parts.

If the water purifier is leaking water from the faucet, filter, or membrane, call a service engineer to check if the valve is properly closed and if the O-rings are in good condition. If the O-ring is cracked or not in a good condition, they need to be fitted tightly to replaced.

5. RO Water Tank Does Not Fill Up

RO Water Tank Does Not Fill Up width=
Another common problem that is found in many RO and UV water purifier is that the water storage tank doesn’t get filled up completely. This is caused due to extremely low water pressure in the purifier. As we mentioned earlier, an RO water purifier needs a minimum pressure of 40 to 60 PSI (Pounds Per Square Inch) to operate properly. If the water pressure is less than 40 PSI, you will need to increase the pressure, which can be done with the help of a water pump.

A damaged RO membrane could also be a possible reason for the water tank not getting filled completely. The semipermeable RO membrane is a barrier that allows only water molecules to pass through to the other side while blocking the passage of water contaminants like dust, dirt, viruses, and bacteria, thus offering clean and safe drinking water. When the membrane gets clogged after a few months of usage, the water filtration process slows down and the water quality degrades. If the membrane is clogged or damaged, it should be replaced to avoid any health issues.

An RO membrane inside a water purifier typically needs to be replaced once a year, depending on the usage. This ensures clean and healthy drinking water.

Best RO Water Purifiers In India

RO Vs UV Water Purifier: Which Is Better?

A lot of people ask this question before buying a water purifier. Is an RO water purifier better for their needs or a UV water purifier. We have answered that question in detail in our dedicated and in-depth water purifier buying guide.

RO Purifiers

With the help of an RO membrane, RO purifiers purify water so that it is safe from contaminants. This helps remove impurities like dissolved solids and invisible particles like bacteria in the water. Regular maintenance is a must for RO purifiers so that it functions properly for a long period of time. These purifiers are best suited for homes that receive below-par water supply, and they are expensive compared to UV purifiers. They are mostly recommended for places with high levels of TDS (total dissolved solids) in the water, commonly known as hard water.

The good thing about RO water purifiers is that it creates a lot of pressure to separate out heavy minerals and salt contents from the water. This decreases TDS levels in the water by forcing the water through a synthetic membrane. These purifiers are the best to use during monsoon as the water quality is not ideal during this season.

Water with 45 to 70 TDS is considered healthy and safe for drinking. However, RO purifiers filter out excessive minerals from the water and cut down the water up to 40 TDS, which is their only disadvantage. However, some RO water purifiers offer an option to adjust TDS levels so that you can get water that tastes good. A good RO costs anywhere between Rs 15,000 to Rs 25,000, depending on the brand and model. You can find the best RO water purifiers in India in our dedicated article. You can also read about an RO water purifier’s maintenance cost, its advantages and disadvantages in our article.

Ultra Violet (UV) Purifiers

UV water purifiers work by using UV rays to kill germs and microbes in the water. As far as maintenance is concerned, UV water purifiers require annual replacement for better performance. However, after a year there is no assurance that the UV light will continue disinfecting the water thoroughly. UV purifiers are more commonly used in Indian homes as they are economical and still do the job of producing healthy drinking water. UV purifiers cost anywhere between Rs 6,500 to Rs 15,000. You can read more about how UV water purifiers work, their maintenance cost, and their advantages and disadvantages.

Water Filtration Systems for Your Faucet

Water filtration is a general term that refers to any system or process that is used to filter out particles and pollutants from water. It doesn’t necessarily need to be a purifier to make the cut. Anything that removes any amount of particles, sediment, bacteria, and the chlorine taste can be called water filtration. If it has a filter of any type, it’s a filtration system.

Types of Filtration

Filtration systems can include activated carbon charcoal filters either designed within a pitcher or included as part of a faucet-mount or tap-installed filter, ultraviolet (UV) light units, reverse osmosis, water distillers (whole system or portable counter), or another form of water treatment process. The term incorporates home filter systems, as well as much larger scale municipal or public water treatment plants. Some appliances are also designed with water filtration features such as refrigerator models which come with onboard filtered water/ice or freestanding water cooler/dispensers.


There are many different types of water filters available, and your buying decisions will be influenced by the present condition of your water. If it’s not potable, you’ll need a process to remove or destroy harmful bacteria, minerals, and pollutants for starters. Your local water expert is the best professional to help you evaluate your choices.

Once water testing has confirmed what is in your water, you will be given remedy options to make your drinking water safe (potable). Installation requirements and costs will be discussed, based on needs and whether you own your home or not. Today, there are many choices, and these systems are much more affordable than they were a decade ago.

Keep It Clean

Whether you choose a small filter or a large unit, maintenance is key to keeping that system working efficiently. That means routine filter changes by yourself or by your chosen water specialist. If you have hard water or, for some reason, there is more sediment and particles in your water, it may require more frequent filter changes. Being proactive with care is an important part of any filtration process. Water filtration systems differ in size, price, installation, and efficiency, but they all in some way improve our water’s quality.

What is Hard Water?

When water runs through limestone or chalk, it can build up a deposit of minerals, including magnesium and calcium. Water with a high concentration of such minerals is known as hard water. Soft water, on the other hand, contains low concentrations of these ions.

Home Filters

Water does not need to qualify as not being potable to benefit from some filtration system. One of the biggest consumer concerns is the chlorine taste left by town water treatment plants. It’s a necessary evil that results from measures taken to make your drinking water safe. You can, however, add an economical and simple filter system to reduce that if you wish to. A good alternative is also keeping a filtered water pitcher in the refrigerator.

Note that not all carbon filters, or larger units, have the same efficiency. There are differences in filtration layers or stages, as well as in the quality of materials. That’s where the product details should be reviewed, so you know what the product will do for your water.

The Pur New Advanced Faucet-Mount Water Filter featured is a good example of a simple measure to improve the quality of water. This is a popular choice for many because of its performance, easy install and affordable price.

Report Identifies Agriculture as Greatest Source of Water Pollution

Water Pollution Solutions: 5 Simple Things You Can Do | Plastic Collectors


A multi-partner report explains that agriculture, not human settlements or industry, is the biggest source of water pollution.

Aiming to increase understanding of the causes and effects of agricultural water pollution and the means to prevent it, the report covers cropping systems, livestock and aquaculture production, as well as the expansion of irrigation, fertilizer, and pesticide use.

It calls for a variety of data-driven outcomes to support science-based policy approaches.

23 July 2018: Water pollution from unsustainable agricultural practices threatens human health and ecosystems, according to a report published by the Food and Agriculture Organization of the UN (FAO) and the International Water Management Institute (IWMI) on behalf of the CGIAR Research Program on Water, Land, and Ecosystems. Noting that the role of agriculture in water pollution is often underestimated by policymakers and farmers, the report titled, ‘More People, More Food, Worse Water? A Global Review of Water Pollution from Agriculture,’ explains that agriculture, not human settlements or industry, is the biggest source of water pollution. Nitrate from farming is the most common chemical contaminant found in groundwater aquifers.

The report aims to increase understanding regarding the causes and effects of agricultural water pollution and the means to prevent its occurrence. It covers agricultural sectors, such as cropping systems, and livestock and aquaculture production, as well as the expansion of irrigation, and fertilizer, and pesticide use. It examines water pollution drivers, pressures and changes in water bodies, impacts on human health and the environment, and responses to prevent water pollution and mitigate its risks. The report explains that annual costs of water pollution from agriculture are in the billions of dollars.

Annual costs of water pollution from agriculture are in the billions of dollars.

The 2030 Agenda for Sustainable Development, the report notes, is expected to influence future policies and strategies and help ensure that water pollution control is prioritized internationally and nationally. In particular, the publication references SDG target 6.3 on improving water quality by reducing pollution.

The publication is structured using the ‘Drivers, Pressures, State, Impact, Response’ (DPSIR) model, a framework for describing interactions between society and the environment that provides a structure for presenting indicators to provide feedback to policymakers on environmental quality and the impacts of policy choices.

Regarding responses, the report discusses policy-level mitigation and remediation responses, such as regulations, economic instruments, cooperative agreements, education and awareness; farm-level responses, such as best practices for agricultural inputs or for erosion control; off-farm responses such as vegetated buffer zones or constructed wetlands; and a systematic methodology for policymakers and practitioners that is applicable at the country, river basin or watershed levels.

The report provides, when available, data and information on pressures and impacts presented by pollutant type, including nutrients, pesticides, salts, sediments, organic matter, pathogens, and emerging pollutants. It also reviews existing models and their potential role, scope, and application. The report highlights concerns related to excessive nutrient application, pesticide overuse, salinity, increased erosion and sediments, and increasing consumption of meat and dairy products.

In its conclusion, the report calls for a variety of data-driven outcomes. They include system-based modeling approaches to support science-based policy; new models capable of simulating interactions between production systems and agricultural inputs; increased data collection to help develop water quality models and translate their results into better water policies; and more education, awareness, and economic incentives for farmers.

The publication also calls for limiting pollutants at the source or intercepting them before they reach vulnerable ecosystems. It recommends ensuring that policies addressing water pollution from agriculture are central to overarching water policy frameworks at the national or river-basin scale and that they influence food security and nutrition policies to encourage the adoption of more sustainable diets.

Test Your Water Quality: Everything You Need To Know

Water is the lifeblood of all ecosystems because it contains and provides precious metals, nutrients, and other necessities of life. Without clean water and clean water, the ecosystem cannot survive, so it is not surprising that contaminated and unhealthy water sources have infected millions of people around the world. To make sure the faucet in your home provides the cleanest water you and your family can drink, you can submit it to a series of water quality tests.

If the tap water shows signs of contamination, such as discoloration, bad smell, or unusual taste, you should test the quality. The water quality tests are carried out in a specialized laboratory. Most Water Filter Companies will provide water quality testing services to those who are concerned about their water supply at the lowest cost. There are three types of tests you can do to help isolate the contaminants and give you a better idea of how to purify the water.


The last thing you want to get in your body when you take a sip of fresh water is a strain of harmful bacteria. Stagnant water can promote bacterial growth and cause serious infections to anyone who drinks it. The bacterial water quality test will examine any bacteria that may cause the disease so you can begin a treatment plan to get rid of it.


It is assumed that water contains a certain amount of minerals and nutrients, but it can be very harmful. The metal test will show if the water contains any defect in the metal that could be harmful to your health or to the health of the appliances that use water. Once you discover the imbalance, it will be much easier to start a treatment plan that will adjust the percentages of minerals and restore your tap water in perfect nutritional harmony.

Chemical products:

Our modern world uses pesticides and other chemicals to treat crops and cleanse our society, but these chemicals can often be harmful to our bodies if they are ingested with drinking water. The chemical water quality test will show you if these harmful chemicals can seep into the soil and your water source.

Water quality test kits

There are two main types of water quality test kits: the water dropper test kit and the test strip test instruments. These tools will help you determine the pH levels in the water and also tell you what is in them.

Water dropper test kit:

The test kit uses dropper dripper and specific reagents. You must isolate the sample from your water supply in a clear glass container or petri dish and use the dropper to place the detector in the sample. If the detector converts the sample to a different color, it indicates that the material you are looking for is present in the water sample.

Test Strips:

There are many types of water quality test kits in the testing sector; each focused on a particular substance. All you need to do to use the test strip kit is to buy a bar that looks for metal or chemical that worries you and shows the tape of your water source. If the material you are looking for is in the sample of water you are providing, the color of the ribbon will change.

Discover why water quality tests are important

Regular water quality tests are essential for anyone who does not use water in the city. Even those who use treated water in the municipality should also undergo a water quality test regularly.

Any number of factors can affect the quality of your water, including industrial waste, runoff from the farm, oil and gas pollution, or even your disposal (or neighborhood) of harmful chemicals and wastes.

If you live in an old house, you may have lead pipes in your home, or water pipes may contain the lead city. If you have any advantage in the water, it is necessary to remove it because the lead will lead to serious brain damage in children and adults. While a regular water quality test is recommended, keep in mind that nothing can be tested in water.

In addition to thousands of chemicals, there are also heavy metals such as lead and mercury, as well as bacteria and microorganisms in the water as well. If your city or city treats chlorinated water, as most of them do, you need to filter it. Chlorine ingestion or prolonged exposure to breast, rectum, and bladder cancer has been linked. Not to mention that the tastes and smells are terrible.

Chlorine is an extremely effective way to disinfect water and kill bacteria and microorganisms in water, but it must be removed before drinking or bathing in it or inhaling steam or mist.

The most effective and efficient way to eliminate these chemicals and toxins and protect yourself and your family is to install an adequate system for water purification. A filter that contains a carbon filter, filter provides no micron, multi-media block, and the exchange of maximum protection from chemicals, minerals, bacteria, and ions toxins.
