RO Troubleshooting

Every household should have water filters to ensure absolute purification of water before drinking it. Among the most popular filtering technology available today in water filters like UV filters, reverse osmosis system (RO) and activated carbon, RO system is the most employed and effective method. The process involves forcing water to pass through a semi-permeable membrane, which is rated at 0.0001 micron, in order to eliminate all water contaminants.

Any normal non-RO water filter uses a single activated carbon cartridge for filtering water. On the contrary, an RO system is capable of desalinating salty sea water and converting the same into purified drinking water. What works against any non-RO water filter is the bigger pore size on the filter media compared to the smaller pore sizes in RO systems, leading to non-filtering of the most diffused and finest substances. As a result, water is way less purified and clean than what is expected.

RO purifying system is greatly vulnerable to pressure and temperatures. It performs great under high pressure, resulting into forceful water outlet devoid of any contaminated substances. However, low water pressure in RO’s leads to lower water production, lesser water volume and persistent flow of water to the drain. It should be noted that the right measure of pressure and temperature is needed to troubleshoot any issues with an RO system.

Symptoms, Causes and Troubleshoot of a poor performing RO system

  • Symptoms: Strange smell, odd taste and odour in water.

    Causes: These are the most common symptoms caused by clogged filter cartridges, presence of any foreign matter in water, dissolved gases in feed water or fouled membranes in the RO system.

    Troubleshoot: Clogged cartridges should be replaced right away, while a fouled membrane should be tested with a TDS process. It should be known that the TDS of clean water is 80% more than the water coming through a fouled membrane. The TDS test is, therefore, inevitable to know whether the membrane in RO needs a replacement.

    The presence of any foreign matter in the holding tank could be the reason for change in colour and smell of water. The solution is to flush out water, clean and sanitize the holding tank. Dissolved gases in RO water leads to change in colour and smell that could be resolved with pre-treatment of feed water. Also, correction in plumbing helps to rectify colour and smell of RO water.

  • Symptoms: Cloudy or milky colour of water in RO system

    Troubleshoot: The milky appearance and diluted appearance in water is due to air in the RO filter system.

    Troubleshoot: The milky appearance of water will disappear by draining the tank once or twice in the initial few days. Know this that this symptom may show after filter changes, but the same is resolved by drainage of water from the tank.

  • Symptoms: Gurgling noise from the drain or faucet of the RO system

    Causes: The condition is caused from the location of the drain saddle, incoming water pressure above 85 psi and limitation in the Black 3/8” drain tube. Sometimes, the gurgling noise is triggered immediately after filter changes when air is expelled from the RO system. After air passes out from the unit, the noises ceases down automatically. Blockage to water flow in the drain tube caused by garbage accumulation produces a peculiar noise as well.

    Troubleshoot: Blockages in drain in the reverse osmosis system can be cleansed with a wire. Besides, when water pressure is above 85 psi, it is ideal to set a pressure restricting valve on the track connected to the drinking water filtration system.

    It is important to inspect the black 3/8” drain tubing from time to time to ensure that its length is as short as possible between the RO faucet and the drain saddle. Make sure that the tube bends downwards without any bends or loops in it that could restrict water flow. It is also an ideal solution to disconnect the tube from the drain saddle from beneath the sink and use an aligned wire coated hanger to clear off any restrictions.

  • Symptoms: Low/sluggish water flow.

    Causes: Choked filtration of reverse osmosis system, fouled membrane, bulky tank of the RO, coiling or twisting of the tube and low feed water pressure less than 40 psi.

    Troubleshoot: Filtration cartridges come with a validity period, so it should be replaced from time to time to avoid blocked filters. The fouled membrane or choked filtration needs replacement as well.

    Do not leave creases in tube since that may block normal water flow. Repairing or straightening the tube is the right solution. Besides, if the tank is bulky, it suggests that there isn’t sufficient pressure to push water to the faucet. In that case, it is necessary to replace the tank.

  • Symptoms: No water comes out when you press the air valve of the RO system.

    Causes: When the tank is full of water and bulky, but the holding tank needs to be re-pressurized.

    Troubleshoot: Start by stopping water feed to the RO system. Keep the RO faucet open and allow air fill in the tank from the air valve by using air compressor or a bicycle pump. This will help force water from the faucet in a steady flow.

    Fill the tank with air when water flow becomes sluggish. Make sure that that the tank is filled with 7 to 9 pounds of air after it becomes fully empty. Once done, close off the faucet and feed water to the reverse osmosis system to help re-fill the tank.

  • Symptoms: Leakage of water from the RO system unit or filter bowls.

    Causes: The leakage is produced by improper/loose fittings of the faucet or tube, inaccurately seated O-ring, impaired/missing fittings and clumsily inserted plastic ferrule on the brass fitting. Loosening of the fittings or improper fittings cause water to leak out.

    Troubleshoot: Contact the dealer for getting a replacement of the missing or damaged O-ring. The dealer makes sure that the O-ring is round and is adequately lubricated before placing it. It is also important to reposition the plastic ferrules correctly, if they are positioned backwards so that their tapered end points towards the valve.

  • Symptoms: Continuous flow of water in RO system.

    Causes: Low pressure in water feed below 40 psi, exhausted auto shut-off valve, low pressure in the RO system and a swirl in the supply line tube.

    Troubleshoot: A booster pump can only increase water pressure which is lower than 40 psi. On the contrary, when feed water pressure is above 85 psi, a pressure restricting valve can get a solution.

    Get repairing for crimps or swirls in the tube. Insufficient amount of pressure in the holding tank is resolved through emptying the tank and refilling it with air. It is an ideal solution to change the auto shut-off valve if it has become non-effective or strained.

  • Symptoms: Very little water in the storage tank.

    Causes: Low incoming water pressure in the reverse osmosis water storage tank results into very little water in the storage tank.

    Troubleshoot: To troubleshoot the problem, first vacate the water tank and then set the tank pressure around 5-7 psi. Mechanics will use a Digital Air Gauge to set an optimal tank pressure to ensure adequate amount of RO water in the storage tank.

    In case of fouled membrane or clogged filters, getting replacement for pre-filters and RO membrane ensure good water pressure. A new filter or membrane typically lasts for 3 to 4 years.

As has been mentioned earlier, the water in reverse osmosis system should get tested for TDS. To recapitulate the above discussion, these are the points to be remembered for:

Troubleshooting high TDS:

  • O-Ring leakage
  • Mechanical damage caused to permeate tube
  • Chlorine destruction
  • Membrane surface abrasion
  • Hydraulic shock
  • Telescoping because of high pressure drop

Troubleshooting low permeate flow:

  • Scaling
  • Colloidal fouling
  • Aged Preservative
  • Membrane dry out
  • Biological fouling
  • Metal oxide fouling

Troubleshooting low salt passage:

  • Compaction
  • Organic fouling

Benefits of Reverse Osmosis Filtration

It is normal for your regular water to change in taste and smell after it passes through an RO system. The technology converts tasty and salty water into clean water in order to eliminate any pungent smell or un-natural colour.

The RO system ensures cleaner, safe and sparkling water with little or no modification in the water’s natural state. Besides, there is no chemical flavour found in RO’s water.

Some of the benefits of RO-treated water include crystal clear ice cubes, authentic flavours of brewed items like tea, beer, coffee, soup that offer a rich and robust flavour. Health drinks and fruit juices made with RO-treated water smell and taste better as well. Owing to low mineral content in RO water, the various domestic appliances like humidifiers, steamers and steam irons can work more efficiently and safely.

In addition to the above benefits, RO water is absolutely safe, different and tastier than distilled water. Unlike distilled water which is boiled and condensed for drinking purpose that has no trace of dissolved solids and nutrients, RO water comprises of salts and minerals.

Another noticeable aspect of RO water is it tastes and smells better than distilled water. Also, distilled water uses electric power supply, whereas RO water uses pressure from household plumbing that requires no electricity.

RO systems combined with minute pore size and high amount of applied pressure to the water usually help to eradicate biological contaminants such as Cryptosporidium and Giardi. The intensity of water pressure and the pore sizes eventually assess the rate of depletion of such detrimental contaminants.

There are a variety of other contaminants that RO is capable of removing that includes chlorides, copper, benzene, atrazine, cyanide, fluoride, lead, sodium, mercury, nitrates, radon, silver, trichloroethylene and trihalomethanes. Aside from minimizing health-related and biological contaminants, RO system is also capable of removing lead from water.

RO water system works efficiently to treat any type of water from contaminants. However, tiny seal leaks or manufacturing defects may prevent any particular units/units from providing guaranteed protection against any kind of biological contaminants. It is to ensure that the RO system is functioning fine and no part of it is under repairs or has any defects that could prevent from producing clear and contamination-free water.

For the safety of our customers, WAQ declares that absolute disinfectant is ensured with cyst-rated and certified products and even post-disinfection apparatus like UV ultraviolet rays. WAQ ensures that there is a deduction of contaminants above 99.9 percent is RO-treated water.

So Rolex created a timepiece for scientists with replica watches sale the Milgauss that was resistant to 1,000 Gauss because of a soft iron core that shielded the movement. For this replica watches sale watch, Rolex wanted something a bit more genteel, yet still a professional watch. The Milgauss more or less had the existing Oyster case, but the dial was inspired by the original Rolex Oyster Perpetual rolex replica sale models with a lightning bolt seconds hand. It was in 1963 that Rolex launched the Oyster Cosmograph that would soon become the Rolex Oyster Cosmograph Daytona. Rolex had been producing chronograph models for at least 30 years at that rolex replica uk point but this was their first real racing world-inspired chronograph watch. No one really knows replica watches uk where the term "Cosmograph" came from, though it is Rolex-speak for chronograph.
