What filters? Pre-treatment, membrane, or post-filter?
Amy5070
Why is it a 5-stage system? What is in the 5th stage?
For my aquarium, I change the pre-filters every three months, and the membrane and resins every six months.
Kenneth7331
I read that if the filters before the membrane are replaced on time, it can last for 2 or even 3 years. In general, I understood that the carbon filter and another one besides the resins should be changed every 3 months.
David
I have a fifth stage post filter.
I change the cartridges every six months.
Melissa3820
Cartridges every six months.
Membrane every three years.
Weekly membrane flushing for 5-7 minutes; if there is a pump, it flushes automatically.
All this was told to me by the guys who installed more than 300 systems and service them.
Brent5588
What is membrane flushing? It constantly flushes itself if it is in operation. If, of course, it hasn't been used for osmosis during the week, then you need to drain some water.
Hannah
If an unclear brownish liquid is coming from the tap, for example, in our city, I change the pre-filters every month. Otherwise, they just start to coke up.

Recommended replacement intervals (depending on the intensity of use and the quality of the source water)
First stage - Polypropylene cartridge 5 microns. Lifespan - approximately 3-6 months.
Second stage - Pressed activated carbon cartridge. Lifespan - 3-6 months.
Third stage - Polypropylene cartridge 1 micron - removal of mechanical impurities, sand, rust, etc. Lifespan - 3-6 months.
Fourth stage - Reverse osmosis membrane. Lifespan - 2-3 years.
Fifth stage - Carbon post-filter. Lifespan - 10-12 months.

sand and rust will remain on the 5-micron filter

You don't need to rinse the membrane yourself. Buy a device like this, it will rinse itself and really extend the life of your membrane.
Eric
Isn't the link for a manual flushing kit (to flush the membrane yourself)? If so, it can be bought cheaper. But here is the automatic one.
James8887
No, the link does not lead to a manual flushing kit. The link leads to a kit that integrates into the system, and the flushing process occurs automatically. According to your links, in one case, it's just a tap and that's it.
Janet5447
It is natural that all of this is integrated into the system, but what makes the process automatic from the set of fittings, the faucet, and the tube? In my opinion, automatic means without your involvement; otherwise, you have to open and close the faucet yourself. Or am I wrong?
Gary6376
So, I have a similar faucet for flushing the membrane on my Chinese osmosis system. They say it increases its lifespan, but I don't really believe that.
Lindsay
I asked the specialists about this issue, and they said that various improvements in pre-filtration and flushing do not change the lifespan; they simply improve the quality of the final water. The lifespan remains the same, for example, 10,000 liters.
Derek7322
A mandate is inscribed on the stone,
and a passport, and a certificate,
that it is clean, they fervently guaranteed...
But the jeweler in another country,
said, returning the stone to me:
"Bottle, damn it, green bottle!"
Robert800
How and where is this valve installed - does anyone have a diagram for the connections? And what is the purpose of flushing, is it to apply water pressure at the membrane outlet? I heard somewhere that using citric acid for flushing can extend its lifespan, but I don't know how to do it.
Rita
Can we include the diagram in the studio? If the membrane is stretched every two months and cleaned inside, it won't replace these vortices. After all, it will be more effective to rinse with a brush.
James
Thank you for the thanks. "Can we include the scheme in the studio? If the membrane is pulled out every two months and cleaned inside, it won't replace these eddies. After all, using a brush will be more effective for rinsing." The schemes I can suggest: Well, I have never tried using such a method for rinsing the membrane. Please write a report if you use it, although it may damage the membrane mesh itself.
Jamie3553
Can the system operate without a four-way valve? Is it even necessary?
Kristen2246
In systems without electrical automation, it is essential! It serves to disconnect the water drain to the sewer; without it, there would be a constant drain.
James8887
What are the consequences of this?
Zoe7451
The most interesting thing is that the system works, but the water meter is stuck - the flow is so weak that the water passes through the impeller and doesn't register the water!
Adam4310
A four-way valve is needed if there is a storage tank. Otherwise, the water will just flow, but where? This only threatens that the membrane's lifespan will be wasted in the sewage.
Beth3383
If you have a working flow limiter (FLOU), then it will be the same on our water meters; mine doesn't count similarly. Well, when there is no tank, it can also be used, for example, by shutting off the water that you are filling the aquarium with; the pressure increases, and accordingly, the four-way valve activates, and water does not flow to the drain!
Stephanie9175
How can I check if the flow limiter is working? It limits the flow, but there is still a constant drain. I simulated its filling by shutting off the water to the tank, but the water still drains – maybe the four-way valve is faulty, or is there nothing to break there? Due to the constant drainage, a lot of condensate forms; I pour out half a liter of water daily from the placed trays.
Kathleen
If there is no filling in the barrel, then both the limiter and the four-way valve are affected. If the barrels are filling up and there is a constant drain, I probably need to change the four-way valve.
Stefanie9771
I had a similar problem with constant water flow after installing a new four-way valve. I solved everything with the help of these devices:
Rodney3101
Well, I have never tried using this method to clean the membrane. Please write a report if you decide to use it, although it might damage the mesh of the membrane itself.
I disassembled the membrane and cleaned it, but honestly, the dirt particles were only on its casing, and there was nothing at the entrance to the mesh slits. So I didn't understand the point of the cleaning. Essentially, we are only cleaning the drainage path to the sewer, that is, the tube behind the flow restrictor. That's all.
Lee
Maybe so, but the TDS meter shows a positive result after rinsing.
Eric
I think the particles that are washed away cannot be seen by the human eye!
Elijah7048
Please tell me, if the membrane is not changed, does it lose its permeability until it completely stops, or does it simply start to allow more permissible impurities over time?
Sarah
and more harmful substances are allowed to pass through, and water loss in drainage also increases.
