If the resource indicator of your filter Aquaphor If the red light comes on or the water pressure at the outlet of the tap has noticeably decreased, this is a direct signal that the cartridge needs to be urgently replaced. Ignoring this warning not only leads to a deterioration in the taste of drinking water, but also to the growth of bacteria inside the clogged water. sorbent, which makes further filtration hazardous to health. Unlike mechanical coarse filters, it is not enough to simply wash the mesh - a complete replacement of the internal unit is required, ensuring the tightness of the connections.
The process of replacing a module in reverse osmosis systems or flow-through filter jugs is radically different in complexity and required actions. In modern systems like Crystal or Morion Quick change technology is used Quick Change, which does not require turning off the water or using special keys. However, even with a simple design, it is important to properly carry out the initial flushing of the new cartridge in order to wash out the coal dust and stabilize the pressure in the system.
Before starting work, you need to make sure that you have a new original module on hand that matches your system model, since there are no universal solutions for all manufacturer lines. An incorrectly selected standard size may not fit into the flask or, worse, allow untreated water to pass past the filter media due to loose seals. In this manual, we will analyze the algorithm of actions for different types of systems, typical installation errors and ways to eliminate leakage problems.
⚠️ Attention: Before replacing the module in flow-through systems, be sure to shut off the water supply through the special valve on the pipeline. If you are changing the cartridge in a reverse osmosis system, you also need to release the pressure by opening the drinking tap until the flow stops completely.
Preparing for replacement and choosing a cartridge
The first step is to accurately identify your filter model, since the modules Aquaphor have different dimensions and connection types. The standard size is always indicated on the body of the flask or in the instructions for the device, for example, K1, K2, K7B or specific designations for osmosis. Using an incompatible cartridge may result in system hydraulic failure and poor cleaning performance.
It is important to purchase original consumables, since high-quality analogues may not have the necessary safety certificates and the required sorbent density. Cheap substitutes often have a shorter lifespan and do a worse job of removing chlorine and heavy metals, which negates the benefit of having a filter. When purchasing, pay attention to the production date indicated on the packaging, since carbon filters also have their own shelf life.
To carry out the procedure, you will need a clean rag to remove moisture and, possibly, a small container to drain the remaining water from the flasks. If you are replacing a module in an under-sink system, ensure the work area is well lit so you can see the condition of the O-rings and threaded connections. Prepare a place for disposal of the old cartridge in advance, as a small amount of process water may leak from it.
- 🔍 Check the markings on the body of the old module before purchasing a new one.
- 💧 Prepare a dry rag and a basin to drain the water from the system.
- 🧤 It is recommended to use clean rubber gloves for hygiene.
- 📦 Make sure that the new cartridge has its original packaging intact.
Replacing the module in filter jugs
The process of replacing the cartridge in jugs Aquaphor is the simplest and does not require special tools or turning off the water. First, you need to remove the old module from the receiving funnel, after which the funnel itself should be thoroughly washed with warm water and a mild detergent to remove mucus and deposits. Pay special attention to the hole in the bottom of the funnel through which water passes, as dirt often accumulates there.
A new cartridge requires mandatory preparation before installation: remove the protective film and immerse it in a container with clean cold water for a few minutes. This procedure is necessary to saturate the porous material with water and release air bubbles, which will prevent the “air lock” effect and allow water to pass normally through the filter. If you skip this step, the water may flow through the cartridge very slowly or stop altogether.
After soaking, insert the module into the receiving funnel until it clicks or fits snugly, making sure it is level. Pour water into the jug and drain the first two or three portions, as they may contain activated carbon in the form of fine dust, which is a normal process. Only after this will the water become suitable for drinking and cooking.
⚠️ Attention: Never wash the cartridge with detergents, soap or hot water, as this will destroy the sorbent structure and render the filter useless. Use only cold tap water for initial rinsing.
Instructions for flow-through systems under the sink
Replacing modules in flow systems Aquaphor series Crystal or Progrand takes just a couple of minutes thanks to the quick change system. Turn off the water supply tap to the filter and open the drinking tap to relieve residual pressure in the line. Wait until the water stops dripping, and only then proceed to dismantle the old blocks.
To remove the module, grasp its housing and turn it counterclockwise until it clicks to unlock, then gently pull it down. Do not use excessive force if the mechanism is stuck - there may be pressure left in the system that needs to be released through the tap. Visually inspect the removed cartridge: if traces of rust or sludge are visible on it, this may indicate problems with the pipeline or the life of the previous cleaning stage has expired.
Install the new module by aligning the guides on the cartridge body with the mating parts in the filter cover and turn clockwise until it stops. The system itself seals the connection, so the use of seals or lubricants is not required. After installing all stages, open the water supply and check the connections for leaks by running a dry cloth over the joints.
☑️ Module replacement checklist
After installing a new set of cartridges, it is necessary to rinse them for 10-15 minutes by opening the drinking tap. During this period, the water may be cloudy due to leaching of coal dust, which is an absolutely normal phenomenon for new sorption blocks. Do not use this water for drinking until it is completely clear.
Features of replacement in reverse osmosis systems
Reverse osmosis systems Aquaphor Morion or classic models have a more complex connection scheme, including a membrane, a mineralizer and a storage tank. Replacing prefilters (mechanical and carbon) is carried out similarly to flow-through systems, but requires care when working with tubes and fittings. It is important not to confuse the sequence of installation of cartridges, since violating the order of steps will lead to rapid failure of the expensive membrane.
The reverse osmosis membrane is changed less frequently, usually every 1.5–2 years, and this process requires care. When removing the old membrane from the flask body, use special pliers or carefully pry it off, being careful not to damage the rubber O-rings. The new element must be inserted with force until it stops, ensuring that the central tube fits into the guide sleeve of the housing cover.
| Module type | Resource (liters) | Replacement period | Signs of wear |
|---|---|---|---|
| Mechanical (PP) | 6000 | 3 months | Change in color, decrease in pressure |
| Carbon | 6000 | 6 months | Chlorine taste |
| Membrane (RO) | 10000+ | 18-24 months | Increase in TDS indicator, slow tank build-up |
| Mineralizer | 6000 | 12 months | No taste, low pH |
After replacing any element in the reverse osmosis system, the storage tank must be completely emptied and refilled. It is also recommended to drain the first full tanks of water down the drain to ensure complete removal of the preservative from the new membrane and carbon dust from the post-filters. Only after this the system is ready for normal operation.
How to extend the life of a membrane?
To increase the service life of the reverse osmosis membrane, regularly change the prefilters (mechanical and carbon). If the mechanical filter becomes clogged, the pressure in front of the membrane will drop and it will stop working normally. If the carbon filter exhausts its resource, chlorine will begin to destroy the polyamide layer of the membrane, which will lead to irreversible damage to the expensive element.
Resetting the indicator and checking operation
Modern filters Aquaphor equipped with electronic or mechanical resource indicators that need to be reset after replacing the cartridge. In models with an electronic control unit (for example, Aquaphor Pro) To reset the counter, you usually need to press and hold the “Resource” or “Reset” button for 3-5 seconds until a beep sounds or the indicator blinks. The exact algorithm depends on the specific model and is described in the device data sheet.
If the indicator does not reset, check the batteries in the electronic unit, as the memory function may not work if the battery is low. In mechanical timers (the dial on the lid of the jug), it is enough to manually turn the dial, setting the arrow to the current replacement month. This will help you remember about the next maintenance procedure after the allotted time.
After installing a new module and resetting the indicator, be sure to check the quality of cleaning using TDS meter (if you have osmosis) or just evaluate the taste and smell of the water. A sharp change in organoleptic parameters for the worse may indicate a defective cartridge or improper installation. In normal mode, the water should be clean, free of foreign tastes and odors.
Main conclusion: Replacing a module is not just a mechanical procedure, but a set of actions to prepare, install and subsequently flush the system to ensure water quality.
Typical errors and ways to resolve them
One of the most common mistakes is insufficient rinsing of the new cartridge, which leads to the consumption of water containing coal dust. Users are often frightened by the black color of the water and think that the filter is defective, although this is a normal situation. It is enough to simply drain more water than indicated in the minimum until the flow is completely transparent.
Another common problem is that the module is not screwed tightly or is misaligned during installation, which causes leaks at the connections. If you notice water on the floor under the sink, immediately turn off the valve and recheck the seating of the cartridge. Sometimes the cause of a leak is a damaged or twisted o-ring that needs to be straightened or replaced.
- 🛑 Forgot to remove the shipping plugs from the new cartridge.
- 🛑 The sequence of installing the filtration stages was mixed up.
- 🛑 We did not relieve the pressure in the system before starting work.
- 🛑 Used hot water to wash the carbon filter.
Also, users often ignore replacement dates, relying only on the visual clarity of the water. However, the adsorption capacity of carbon and the bactericidal properties of silver are exhausted long before the filter stops passing water. The exploitation of the exhausted resource turns the filter from a treatment plant into a breeding ground for bacteria.
⚠️ Attention: If, after replacing the module, the pressure in the system drops critically low, check that all shipping films and plugs have been removed from the new cartridge. A forgotten protective film completely blocks the flow of water.
Expert tip: When replacing a cartridge in an under-sink system, place a towel under the filter. Even with the water turned off, about 100-200 ml of liquid remains in the tubes and flasks, which will inevitably spill during dismantling.
Frequently asked questions (FAQ)
How often do you need to change the module in the Aquaphor filter?
The frequency of replacement depends on the filter model and the quality of tap water. For jugs, the standard resource is 150–300 liters or 1 month. Flow filters last 3–6 months, and reverse osmosis membranes last up to 2 years. Always rely on the resource indicator readings or a decrease in filtration speed.
What should I do if the water is black after replacing the cartridge?
The black color of the water is given by activated carbon, which is washed out of the new filter. This is not a defect, but a technological feature. It is necessary to drain 2-3 full containers (for a jug) or run the water into the drain for 10-15 minutes (for flow-through systems) until it becomes clear.
Can the Aquaphor cartridge be washed and reused?
No, cartridges Aquaphor are disposable consumables. Washing with water only cleans the surface of mechanical contaminants, but does not restore the adsorption capacity of carbon or the ion-exchange capacity of the resin. Reusing an old module is ineffective and unsafe.
Why does the filter hum or whistle after replacing the module?
The noise may be due to air entering the system during replacement. It usually goes away on its own some time after the start of use. If the noise persists for a long time, check that the connections are tight and that there are no leaks that could create a whistling sound at high pressure.
Do O-rings need to be lubricated during installation?
Most modern models Aquaphor Quick replacement technology is used, where lubrication is not required and is not even recommended by the manufacturer. Rubber seals are designed to run dry or are already factory lubricated. The use of foreign oils can cause the rubber to swell and lose its seal.
