Direct assembly of a water purification system Geyser Prestige without a mineralization module requires precise adherence to the sequence of connecting flexible hoses, since the absence of a fifth stage changes the logic of the flow movement to the storage tank. If you plan to install reverse osmosis For this model, ignoring the connection of the mineralizer, it is important to understand that the water after the membrane will flow directly into the hydraulic tank, bypassing the additional calcium cartridge. An error in connecting the tubes at this stage often leads to constant drainage of water into the drainage or a lack of pressure build-up in the system, which makes normal operation of the filter impossible.
Unlike the complete set, where purified water passes through a post-charcoal filter and mineralizer before entering the tap, a simplified scheme Geyser Prestige involves a shorter line from the tank to the drinking tap. This reduces flow resistance and makes filling the tank a little faster, but requires care when installing the John Guest connection fittings. Correct connection of the tubes ensures the tightness of the circuit and effective flushing of the membrane element, which is critical for extending its service life and the quality of the resulting water.
Design features of the model without a mineralizer
System Geyser Prestige in the basic configuration or in a modification without a mineralizer consists of three preliminary stages of purification, a block with a reverse osmosis membrane and a post-charcoal filter. The absence of a mineralizer means that after passing through the membrane, the water is not artificially enriched with salts, maintaining its natural structure after purification. In this configuration, the tube from the membrane body is directed directly to the inlet of the storage tank, bypassing unnecessary connections, which simplifies the overall hydraulic circuit.
It is important to consider that reverse osmosis produces very highly purified water, often called “distilled” in everyday life, although technically this is not entirely true. Without a mineralizer, such water has a low pH and can be aggressive to some materials, but it is completely safe and healthy for drinking and cooking. The pipes in such a system experience standard water pressure, so the quality of the connections and the condition of the O-rings play a decisive role.
Design of John Guest fittings used in Geyser Prestige, allows connections to be made without the use of glue or thread seals. The tube is inserted into the fitting all the way, secured with an internal collet clamp, which ensures tightness even during pressure surges in the line. When assembling a circuit without a mineralizer, the number of connection points is reduced, which theoretically reduces the risk of leaks if all elements are installed correctly.
- 🔹 The absence of a fifth stage simplifies installation and reduces the number of necessary connections.
- 🔹 Water after the membrane goes directly into the hydraulic tank, bypassing additional cartridges.
- 🔹 Reducing hydraulic resistance has a positive effect on filtration speed.
- 🔹 Requires precise cutting of tubes at 90 degree angle for secure fit.
⚠️ Attention: Before starting assembly, make sure that all rubber seals on the ends of the flasks and fittings are lubricated with silicone grease and are not damaged, otherwise the tightness of the system will be compromised.
Necessary tools and preparation for installation
For high-quality installation of the system Geyser Prestige with reverse osmosis you will need a minimum set of tools that any home craftsman can find. A critical element is a special pipe cutter, which allows you to make a perfectly straight cut of the plastic tube, which is a prerequisite for the operation of collet clamps. Using scissors or a knife often causes the tube to flatten or create burrs that prevent the fitting from working correctly.
In addition to the pipe cutter, you will need an adjustable wrench to tighten connections on the water main and a wrench to unscrew the caps of the filter flasks. It is also necessary to prepare a container for draining water when washing new cartridges and FUM tape or thread for sealing threaded connections on the tee and ball valve. All system components Geyser Prestige must be collected in a clean place so that dust does not get inside the flasks.
Before starting work, be sure to turn off the cold water supply and relieve pressure in the system by opening the mixer. This will prevent flooding of the room when inserting a tee into a water pipe. Check the completeness of the kit, making sure that all the necessary tubes of different lengths are included, which are color-coded or letter-coded for ease of installation.
- 🔸 Special pipe cutter for polyethylene pipes with a diameter of 1/4 and 3/8 inches.
- 🔸 Adjustable wrench and wrench for servicing filter flasks.
- 🔸 FUM tape or plumbing flax for threaded connections.
- 🔸 Container for collecting technical water during primary flushing.
Only use the supplied pipe cutter or equivalent quality as any bevel when cutting the pipe will cause leakage at the connection to the John Guest fitting.
Step-by-step diagram for connecting tubes
System assembly Geyser Prestige begins with installing plugs on unused ports and connecting the input line. Water from the water supply through a ball valve and a tee enters the first stage of the prefilter, designated as IN or Feed. From the first filter, water flows into the second, then into the third, after which it enters the reverse osmosis membrane housing, where the main separation into clean water and concentrate occurs.
The key point of the scheme without a mineralizer is to connect a clean water tube. The tube coming out of the membrane (usually blue or marked Product) is connected directly to the fitting of the storage tank. In the full version there would be a mineralizer here, but in our case we connect the outlet of the membrane to the inlet of the hydraulic accumulator, observing the direction of flow. Drainage tube (Drain) is discharged into the sewer through a special seeder clamp.
From the storage tank, the tube goes to the inlet of the post-charcoal filter (fourth stage), and from the outlet of the post-filter, water is supplied to the drinking tap. It is important not to confuse the inputs and outputs on the post filter housing, although in some models they may be symmetrical; the direction of flow is usually indicated by an arrow on the housing or in the instructions. All connections must be made with a characteristic click, and the tube must be inserted all the way.
| System element | Tube designation | Where to connect | Tube color (example) |
|---|---|---|---|
| Water inlet | IN / Feed |
1st pre-filter | Blue |
| Output to membrane | To Membrane |
Entrance to membrane housing | Blue |
| Clean water | Product |
Storage tank | Blue |
| Drainage | Drain |
Sewerage (clamp) | Black/Gray |
| Tap outlet | Faucet |
Drinking tap | Blue |
☑️ Checklist for correct connections
System startup and initial flushing
After the tube connection diagram Geyser Prestige is assembled; it is necessary to perform an initial start-up, which includes washing the filter materials. Carbon prefilter cartridges may contain coal dust, which, without thorough rinsing, can quickly contaminate the membrane. To do this, it is recommended to temporarily disconnect the inlet tube to the membrane unit and rinse the first three flasks by running water directly into the drain.
When filling the tank for the first time, the process may take 1 to 2 hours depending on the pressure in the water supply and the temperature of the water. During this period, the system will periodically discharge water into the drain, which is normal operation. reverse osmosis. Do not open the drinking tap until the tank is completely filled and the water supply is automatically shut off by the valve.
After filling the tank, it is recommended to completely drain the first portion of water, as it may have a specific taste of the preservative that is used to treat new membranes. Only after 2-3 cycles of completely filling and emptying the tank does the water acquire a stable taste and is ready for use. Check all connections for drip leaks during the first hour of operation.
- ✅ Rinse the prefilters until the black residue in the water disappears.
- ✅ Drain the first 2-3 tanks of water to remove the preservative from the membrane.
- ✅ Check for leaks under all flasks and fittings.
- ✅ Make sure that the drainage flow stops when you close the tank tap.
⚠️ Attention: If, after filling the tank, water continues to constantly drain into the sewer, check that the ball valve on the tank is completely closed and that there is no blockage in the drain clamp.
Why can water constantly flow into the drain?
This may occur due to low pressure in the water supply (less than 2.5-3 atmospheres), a malfunction of the shutoff valve, or improper adjustment of the drainage flow. In some cases, it is necessary to install a pressure booster pump.
Diagnosing common installation problems
The most common problem with self-installation Geyser Prestige is incorrect insertion of the tubes into the fittings. If the tube is not completed or cut askew, water will drip out of the connection even at normal pressure. Also, users often confuse the inlets and outlets on the filter housings, which disrupts the hydraulics and prevents the system from gaining pressure.
Another common mistake is ignoring the condition of the rubber seals on the flask lids. A twisted or dried rubber band will cause water to spurt out from under the lid the first time you turn it on. Before screwing the flask, be sure to make sure that the rubber lies flat in its groove and is lubricated.
If the system hums or vibrates, this may indicate air in the pipes or the pressure relief valve is working. In a circuit without a mineralizer, such sounds are less common due to the smaller number of connections, but they cannot be completely eliminated. Regularly checking connections and timely replacement of cartridges will help avoid most operational problems.
The main cause of noise and leaks is a not fully inserted tube into the John Guest fitting or a twisted rubber seal on the flask.
Maintenance and replacement of filter elements
Regular system maintenance Geyser Prestige with reverse osmosis consists of timely replacement of pre-filter cartridges, post-filter and the membrane itself. Pre-filters (mechanical and carbon) are changed every 6 months, since their resource directly affects the service life of the expensive membrane. The post-charcoal filter also requires replacement once a year to maintain the organoleptic properties of the water.
A reverse osmosis membrane lasts from 1.5 to 3 years, depending on the quality of the source water and the pressure in the system. If the performance of the tank decreases or the quality of cleaning deteriorates (the TDS meter increases), the membrane element must be replaced. In models without a mineralizer, water quality control is especially important, since there is no additional stage of taste correction.
Whenever you replace cartridges, it is necessary to disinfect the flasks and check all connections. Use of original consumables Geyser guarantees sizing and filtration quality. Do not forget to carry out an initial flushing procedure after each replacement, similar to starting a new system.
- 🔄 Replace pre-filters (1-3 stages) every 6 months.
- 🔄 Change the post-charcoal filter (4th stage) once every 12 months.
- 🔄 Monitor the condition of the membrane using a TDS meter.
- 🔄 Disinfect the flasks every time you replace cartridges.
How often do you need to change the membrane in Geyser Prestige?
The service life of a reverse osmosis membrane is from 1.5 to 3 years. The exact period depends on the quality of tap water, the pressure in the system and the regularity of replacing prefilters. If the TDS of purified water has increased sharply or the performance of the tank has decreased, it is time to change the membrane.
Is it possible to connect the mineralizer later?
Yes, the Geyser Prestige design allows you to retrofit the system with a mineralizer at any time. To do this, you will need to purchase a separate mineralizer cartridge and an additional tee fitting to separate the flow of clean water before the post-filter.
Why does the water after the filter have a strange taste?
New water may taste like a preservative (food acid) used to treat the membrane. It is necessary to drain 2-3 full tanks. If the taste remains, check the date of manufacture of the carbon filters - old carbon may give off an unpleasant odor.
What water pressure is enough for osmosis to work?
For the Geyser Prestige reverse osmosis system to operate effectively, a water supply pressure of 3 to 6 atmospheres is required. At a pressure below 3 atmospheres, the performance of the membrane drops, and the system can constantly drain water into the drain.
