Aquaphor filter: replacing cartridges - complete instructions

Timely replacement of the cartridge in a water purification system is not just a manufacturer’s recommendation, but a critically important procedure for family health. When a resource filter element exhausted, it ceases to retain harmful impurities and, even worse, can become a source of secondary pollution, beginning to release accumulated salts back into the water. Many system owners Aquaphor They ignore the deadlines, relying on the visual purity of the water, but the microbiological processes inside the cartridge go unnoticed by the eye.

The replacement process may seem complicated the first time, but it actually only takes a few minutes and doesn't require any special tools or plumbing experience. In this article we will analyze the algorithm of actions for various models, including popular jugs, flow-through systems under the sink and main filters. You will learn how to properly prepare the system, avoid common installation mistakes, and what to do if water drips after installation.

It is important to understand that failure to install a new module can lead to leaks and failure of the entire cleaning system. We will pay special attention to the nuances of sealing and proper flushing, since these are the steps that most often raise questions among users. Follow these step-by-step recommendations to ensure your water is always safe and tasty.

Replacement frequency and signs of resource depletion

Each cartridge has a strictly defined resource, expressed either in liters of filtered water or in operating time. For standard cartridge jugs type B5 or B10, the average service life is 1-2 months, depending on the hardness of the source water and the volume of consumption. Series flow modules KVV or KVB last longer - usually from 4 to 6 months, and reverse osmosis membrane systems require attention once every 1-3 years, depending on the type of stage.

You can determine that a resource has been exhausted not only by the calendar, but also by indirect signs. If you notice that water has become slower to fill into the container or the pressure in the spout has weakened significantly, this is a sure sign that filter medium clogged with mechanical impurities. You should also be wary if there is a foreign taste or odor in the water, or if it is no longer soft to the touch, which is especially true for regions with high hardness.

⚠️ Attention: Using a cartridge beyond the stated period can lead to the proliferation of bacteria inside the sorbent and deterioration of water quality, making filtration pointless and even dangerous.

There are several factors that can reduce the manufacturer's stated service life. These include sudden pressure surges in the central water supply, the presence of suspended rust particles in the water and exceeding the permissible water temperature. Regular monitoring of the system condition will help you react in time and replace the element before the critical moment occurs.

Necessary tools and workplace preparation

Before you begin dismantling the old module, you must properly organize your workspace to avoid contamination of the system and damage to property. You will need a clean towel or rag to line the bottom of the sink or the floor under the filter, as residual water will inevitably drain from the system. Also prepare a container to drain the liquid from the flask so that it does not spill onto the floor or into the sink if there is food there.

For most models Aquaphor no specialized tool is required, but in some cases you may need a special wrench for unscrewing the flasks, which comes with the main filters. If you have a model with quick-release modules, then just your hands and perhaps scissors to trim the tube will be enough. Make sure you have a new cartridge on hand that matches your filter model exactly.

An important stage of preparation is shutting off the water supply. For flow-through systems under the sink, it is necessary to close the inlet valve on the cold water pipe. If there is no separate valve, close the common riser in the apartment. This will avoid a fountain of water when disconnecting the tubes and will make it possible to calmly carry out all manipulations without haste and stress.

Replacing the cartridge in filter jugs

The process of replacing a module in jugs Aquaphor is the simplest and does not require shutting off the water. To begin, remove the funnel cap and remove the old cartridge by simply pulling it up. It is not recommended to apply excessive force or use tools, as the plastic may crack and the cartridge itself may collapse, spilling coal chips into the jug. Once removed, thoroughly rinse the funnel and pitcher with warm water and a mild detergent to remove any mucus or residue.

The new cartridge must be prepared before installation. Shake it a few times to compact the filter media and remove the protective film from the opening on top. Then immerse the module in a container of cold water and shake it vigorously underwater several times. This procedure is necessary in order to activated carbon saturated with water and displaced the air, otherwise the first portions of water will come out with bubbles and black suspension.

Install the prepared cartridge into the funnel, aligning the spout of the module with the hole in the bottom of the funnel. Press it tightly, but without fanaticism. After installation, fill the water to the top and let it filter completely. It is better to throw out the first portion of purified water, as it may contain remnants of activation dust from the new coal. Only after this can the jug be used for drinking and cooking.

Instructions for flow-through systems under the sink

Replacing modules in flow-through systems such as Crystal, Trio or Modern, requires greater care. After turning off the water, open the purified water tap to relieve any residual pressure in the system. Wait until the water stops dripping. Next, disconnect the tube from the module inlet fitting by pressing the locking ring (collet) and simultaneously pulling out the tube. Be prepared for a small amount of water to leak out of the tube.

Remove the old cartridge from the body-flask or simply unscrew it if you have a block-cartridge type system (as in the model Modern). In systems with flasks, it may be necessary to unscrew the flask itself with a special key. When installing a new element, pay attention to the direction of flow indicated by the arrow on the body - water should flow in the direction indicated by the manufacturer. Insert the new module as far as it will go and snap the retaining ring or screw it into the housing.

After installation, open the water supply valve and carefully inspect the connections for leaks. Open the clean water tap and drain the first 5-10 liters. This is necessary to flush out coal dust and stabilize the pressure in the system. If you are using a model with a mineralizer, it is also better to drain the first couple of liters to stabilize the salt balance.

Maintenance of main filters and osmosis

Main-line filters and reverse osmosis systems have a more complex design and require a special approach when replacing cartridges. In-line flasks often use higher pressures than in flow-through flasks, so the quality of the sealing rubbers plays a key role. Before tightening the flask, be sure to lubricate the rubber ring silicone grease, approved for contact with drinking water. This will prevent the ring from skewing and ensure a tight seal.

In reverse osmosis systems, replacement is carried out in stages. First, the prefilters (mechanical and carbon) are changed, then the membrane (less often) and the postfilter. After replacing the cartridges in the osmosis system, the tank must be full, which must be completely drained 2-3 times. This is necessary in order to wash the preservative out of the new membrane and stabilize the operation of the automatic valve.

⚠️ Attention: When replacing cartridges in main filters, make sure that the flask is screwed in completely, but not overtightened, otherwise the thread may burst under the pressure of the water supply.

Pay special attention to the sequence of installation of modules. In flow-through systems, water must pass through stages in a strictly defined order: first mechanical cleaning, then sorption and softening, and finally finishing conditioning. By mixing up flasks or modules, you risk quickly damaging expensive elements, for example, clogging the membrane or ion-exchange resin with large rust.

Frequent errors and troubleshooting

One of the most common mistakes is neglecting to flush a new cartridge. As already mentioned, activated carbon contains dust, which will end up in the kettle or pan without rinsing. In addition, users often forget to remove the shipping plugs from the fittings of the new module, which results in a lack of water flow or rupture of pressure connections.

Another problem is the wrong direction of flow. On the body of each flow cartridge Aquaphor There is an arrow indicating the direction of water movement. Installing the module the other way around will result in water either not flowing at all, or bypassing the filter load without being purified. In systems with flasks, it is important not to confuse the flasks themselves if they are not numbered, since they may contain different types of cartridges.

If after replacement you hear hissing or see bubbles in the bulb, this may indicate a poor-quality tube connection. Try disconnecting the tube, cutting off 1-2 cm from its edge (to get an even cut) and reinserting it until it stops. An even cut of the tube is the key to a tight connection in quick-release fittings.
