Over time, the cartridges of various filters cease to perform their functions. They require timely replacement. Different systems provide a certain technology for performing this procedure. Therefore, before starting work, you need to consider the manufacturer's instructions. How to change the water filter will be discussed in detail later.
Varieties of filters
To change the water filter, you need to determine which category of devices it belongs to. Household systems can be of three types. The first category includes pitcher filters. They are made in the form of a container with a spout and a lid. This shape resembles a jug. There is a removable cartridge in the middle of the filter. It is changed at the frequency specified by the manufacturer (depending on the characteristics of the water in the region). As a rule, such a procedure is carried out at least once every 3 months.
The second group includes filters that are installed on the sink. Comes witha plastic cylinder (can be transparent or opaque), inside which the cartridge is located. A small faucet and a water cutter are also supplied with this purifier. These cartridges need to be replaced on average every six months.
The third group includes the most advanced reverse osmosis filters. They come with three containers in which cartridges with different fillers are installed (depending on the characteristics of the water in the region). The system also includes a membrane. Through it, the water, passing through the preliminary filters, passes the finest purification. As a result, there are practically no impurities left in it. To give it a familiar taste, a mineralizer is installed in the system. It enriches the water with essential trace elements. In such a system, both cartridges and a membrane with a mineralizer are changed. The maximum life of the system without maintenance is 1 year.
Filter jug
Customers are often interested in how to change the water filter "Aquaphor", "Barrier" or other manufacturers. If the question concerns varieties such as a jug, the procedure is very simple.
After the deadline, you need to buy a new cartridge. It is worth considering that such types of cleaners are produced by many manufacturers. The seat for the cartridge can vary significantly. Therefore, going to the store, you need to know the name of your filter.
Cartridges differ in size. However, there are also universal models. They include a specialsealing ring. It allows you to install such a cartridge in almost any jug. The cartridge is selected depending on the characteristics of the water in the region. The filler for products of the same manufacturer may differ.
You need to pull out (unscrew) the old cartridge. Usually it is removed easily, without requiring any effort. The jug is washed. Next, you need to install a new cartridge in the seat. Water is taken into a jug. You have to wait until it goes through the cleaning process. The water is completely drained. Repeat the procedure 2 more times. After that, you can drink the water that the jug has filtered.
Replacing filter cartridges at the sink
When learning how to change the hot or cold water filter, you should carefully read the manufacturer's instructions. If a cleaning system is installed on the sink, you can perform the steps to replace them yourself. This filter can consist of one, two or three stages of purification. The cartridges inside are different, eliminating the contaminants that are present in the water of this region.
Need to buy new purifiers. To purchase a suitable one, you need to take a picture of the tag on the old cartridges. If the system has 3 stages of cleaning, then the first filter must be coarse. The second step is the removal of organic compounds, chlorine. The third cartridge removes organic matter from the water, but the degree of purification in this case will be finer.
To unscrew the flask in which the filter is installed, you need to use a special key. It is sold in specialized stores orsupplied with the system.
Dismantling
When considering how to change a cartridge in a water filter, you need to pay attention to the procedure for dismantling the old purifier. First, the water supply to the system is shut off. Spinning the flask can be difficult, even with a wrench. This is caused by the presence of internal pressure in the system. It needs to be reset.
For this, many designs provide for a special button. It is located at the top of the filter. After that, the pressure decreases. If the manufacturer did not provide such a lever in the design, you need to open the tap that follows the filter.
After that, the flask is easily unscrewed. There will be water in it, so you need to be careful. A cartridge is taken out of the flask. On its ends there are sealing gum. If they are soft, you can remove them, rinse and leave for another cartridge. The new filter may have stiffer rings.
Filter maintenance
When learning how to change the cold water filter, you should also pay attention to the flasks in which the cartridges are installed. Most often they are washed. Inside there may be rust, mucus and other contaminants. They are carefully removed from the flask. Detergents are not used.
If the flask is already quite worn out, it is better to install a new glass in its place. To do this, press the button on the case. The flask is unfastened. Next, a new container for the cartridge is installed in its place. It can be purchased from specialiststores.
After that, a new cartridge is installed in the seat of the flask. It must be tightened with the same key. If the rubber bands on the cartridge are hard, this procedure may cause some difficulties. Therefore, the seals are replaced with old soft rubber bands if necessary.
Complete replacement
When considering how to change the water filter, you should pay special attention to the procedure for completing this process. After installing the cartridge, the flask is twisted until it stops. You need to check the tightness of the system. To do this, very smoothly open the water supply tap. You need to keep an eye on the system. Water must not seep through the joints.
If there is a leak, turn off the water and tighten the flask even more. If this does not help, you need to unscrew the flask and inspect the o-rings. Seals must be replaced if damaged.
If there is no leakage, the water is drained for about 10 minutes. After that, the system is ready for operation.
Geyser filter
Many people in our country have a Geyser filter installed. His service has several nuances. How to change the Geyser water filter? First shut off the water. Then the first stage of cleaning is unscrewed with a key. After replacing, the flask is twisted according to the above scheme.
The central bottle must be unscrewed manually. It is completely changed. First, the cartridge is fixed, and then the flask. The third stage is serviced in the same way as the first. After that, you need to check the system for leaks. During normal operation, you canuse the filter as intended.
Reverse osmosis
How to change the water filter in the reverse osmosis system? In this case, the procedure is somewhat more complicated.
Flasks are removed and serviced in the same way as described above. The only difference is the requirement that is put forward to install a new cartridge. When it is in the flask, distilled water must be poured into it. Otherwise, air bubbles that remain in the system will damage the membrane. It needs to be changed every 1-1.5 years.
To remove the membrane, you need to detach the red retaining clip. Next, you can disconnect the hose. To do this, you need to press a little on the ring. The hose is pulled towards you. This action is carried out on both sides of the system. After that, the device can be dismantled. It is removed from special brackets. Next, the hose that fits the membrane is disconnected. The field of this will be possible to unscrew the cover. The device is dismantled with pliers.
After that, you can install a new membrane. The lid is screwed on. Hoses are attached to it on both sides. The system can then be operated normally.
Having considered how to change the water filter, you can perform all the steps yourself. The quality of water consumed by a person depends on the timely replacement of cartridges and other elements of the system.
