The sequence of installing water purification filters is determined after receiving the results of its study. Its features will help select cartridges with the required characteristics. For example, foamed polypropylene in the first purification section will quickly become unusable if water with an increased amount of iron in its composition flows through the pipes. The iron removal filter is installed before the softening column. When the water acquires the required transparency, you can begin softening it.
The last stage is usually the installation of an activated carbon cartridge. It gives the work of the first two the finishing touch, eliminating unpleasant odors and improving the taste of purified water.
For reverse osmosis systems, you should contact an RO Service in Patna. The only distinctive feature is that before the first stage, a pre-treatment stage is added to reduce the load on the membrane.
Water purification stages
Water is irreplaceable. We bathe and wash in it, drink it to maintain health, and cook food. Heavy substances in liquid and biological environments can negatively affect human health. The correct order of purification stages in the filter allows for eliminating the negative impact of water:
- Mechanical cleaning from heavy impurities.
- Softening water to improve its taste, eliminate foreign odors, and increase transparency.
- Purification from chlorine and organic impurities by using a compressed carbon block for purification from chlorine and organic contaminants.
For example, a metallic taste indicates a high chlorine content. Such a base will not make the prepared dish tastier. Liquid with a high iron content dries the skin and negatively affects the service life of household appliances. Biological organisms develop in poorly purified water. They can cause mild discomfort in the abdominal cavity and more complex consequences.
How do cartridges get replaced?
Manufacturers recommend changing the first cartridge once every four months. The second and third – as their resource is exhausted. Their working life is usually measured not in days but in liters of liquid passed through them. The service life of each cartridge can be found in the instructions for the flow filter or on the manufacturer’s website.
You can change the cartridges yourself or use an RO service near me. The process will seem easy after several independent replacements. It is essential to perform all actions in the correct order:
- Shut off the water supply to the risers.
- Release the pressure in the cold and hot water supply pipes by opening any tap after turning it off.
- Turn off the tap to the filter.
- Remove the filter from the cabinet to make it easier to work with. Please do not disconnect the supply hoses; their length should be sufficient.
- Open the first cylinder using the key provided.
- Replace the cartridge in the cylinder and tighten it with the same key.
- Repeat the steps with the following two cylinders. If necessary, rinse the flasks and install new cartridges.
- Return the system to the kitchen cabinet.
- Open the water supply to the cartridges.
- Open the cold and hot water supply to the risers.
- Open the filter’s tap to check its operation. The pressure should not be intense so that the water has time to go through all the stages of purification.
Although replacing filter cartridges from different manufacturers may differ slightly, it is generally identical for most models.
Features of replacing water filters
Water is most often supplied to apartments after some degree of purification. The home filter only needs to remove heavy impurities. Also, jugs and tap attachments are used in apartment buildings to purify running water. Their strong points are mobility and compactness.
Reverse osmosis units can be used in apartment buildings. But they are most popular among owners of private houses. Different areas have different properties of underground water. Therefore, a private house must have a high level of purification of drinking water with various cartridges. In addition to the reverse osmosis system, ultraviolet purification systems, ionizers, and alkaline balance normalizers are installed.
