Older building stock
Sediment and rust come to the fore
As building plumbing ages, the particles the water carries increase. Here the decisive stage is the sediment filter that comes before the membrane.

Technical Service
Water purifier service in İstanbul
The quality of mains water in İstanbul varies from district to district; in buildings with old plumbing, water carries sediment and limescale by the time it reaches the home. If the stages of the unit are not renewed on time, the quality of the outlet water falls. We carry out maintenance, repair, filter changes and commissioning in all 39 districts.
After leaving the treatment plant, water reaches the home through kilometres of mains and, more often than not, decades-old building plumbing. Sediment, rust and limescale can enter the water on that journey.
- The mains Pressure and chlorine levels vary from area to area.
- Building plumbing Rust and sediment can enter the water in old pipes.
- The stages of the unit Once saturated they stop holding anything back; this is where the real issue lies.
A unit whose filters are not changed on time does not just lose efficiency: the blocked stage lowers the pressure, tires the reverse osmosis membrane, and the values of the outlet water start to approach those of the mains supply.
What changes from area to area?
The points below are a starting point, not a fixed rule — even within the same district the result changes with the building's plumbing. The only thing that establishes the right build is measuring the water: TDS, hardness and pH.
High hardness
Limescale and TDS come to the fore
Where the dissolved solids load is high, the reverse osmosis stage comes into play; it is not only drinking water that is affected, but the life of heated appliances too.

Relatively soft water
Minerals can be preserved
Where hardness is not a problem, ultrafiltration is enough for most homes; particles and microbiological load are held back while the natural mineral structure of the water is preserved.

Which system suits which need?
Reverse osmosis
If TDS is high
Passing water through a semi-permeable membrane, it greatly reduces the dissolved solids load. It is preferred where hardness and TDS are high.

Ultrafiltration
To keep the minerals
It holds back particles and microbiological load while preserving the mineral structure of the water. It is enough in areas where hardness is not a problem.
See the products
Ultraviolet
Microbiological risk
It renders microorganisms inactive without adding chemicals. It is used not on its own but as the last stop after the filtration stages.

Scale of the business
By flow
In a restaurant, hotel or production plant the choice is set by flow, not by technology: daily consumption and the peak demand give the capacity directly.
See the products
Filter change
Periodic replacement of sediment, carbon, membrane and mineral filters. The size and micron rating of the part fitted are chosen to suit your unit.
Fault repair
On-site work for leaks, pump faults, low pressure, blocked membranes and control board problems.
Installation and commissioning
Installation is a service · plumbing is the customer’s responsibility
Periodic maintenance
Checking the stages of the unit, cleaning the internal surfaces and measuring the outlet water. The interval is set by the hardness of the water and how heavily the unit is used.
Water testing and analysis
Measurement of TDS, hardness and pH. The result determines which stages are needed and the filter change interval.
Industrial service
Maintenance and repair on restaurant, hotel, production plant and building inlet systems. Planned according to flow and capacity.
When are the stages changed?
The intervals below are a starting value. If the water is hard and daily consumption is high, the period shortens; the exact interval is set by measuring the outlet water.
| Stage | Interval | What happens if it is not changed |
|---|---|---|
| PP sediment filter | 6–12 months | Flow falls and the following stages block early |
| GAC and CTO carbon filters | 6–12 months | Chlorine is not held back; the membrane is damaged |
| Reverse osmosis membrane | 12–24 months | The TDS value of the outlet water rises |
| Mineral (taste) filter | 12–24 months | The taste and pH balance of the water change |

Frequently asked questions
How often should a water purifier filter be changed?
In the filters we use, the pre-filter set (PP sediment, GAC and CTO carbon) is changed every 6–12 months, and the mineral (taste) filter and reverse osmosis membrane every 12–24 months. These periods shorten with harder water and heavier daily use; the exact interval is set by a TDS measurement of the outlet water.
Which districts of İstanbul do you serve?
We serve all 39 districts of İstanbul. Each district has its own page with information specific to that area and a direct way to get in touch.
Do you charge extra for the visit?
No. The team comes out and does the change, maintenance or repair on the spot; payment is taken once the work is done. There is no separate visit or survey fee — what you pay is for the work carried out.
Is installation included in the price?
The system is delivered ready to install; it only needs to be connected to the inlet and outlet lines. If valve setup is required, we provide free support over a video call. Installation and commissioning fall under our service work and are subject to a service fee. Plumbing labour and any pipes, valves and fittings are not included in the price; these items are the customer’s responsibility.
What does the warranty cover?
There are two separate warranties. The unit you buy from us is covered by 2-Year Warranty; consumables that come in the box, such as filters, membranes and resin, fall outside that cover, because their life depends on use and on the quality of the water. Filters we fit during service carry a 1-year warranty. Misuse is not covered.
How do you decide which filter needs changing?
When our service team arrives, they first measure your water; which stages need replacing is decided from that measurement. The packages on the site are a starting point; if the measurement shows that fewer stages need changing, the price comes down accordingly.
Which brands of unit do you service?
We make no distinction between brands. Just send us the model of your unit and, if you know it, the filter size; we will tell you the compatible part and the work to be done in advance.
How long does servicing a water purifier take?
A filter change and general check take 30–45 minutes on most units. A fault repair can take longer depending on the problem; if a membrane or pump has to be replaced, the work takes 1–2 hours. We tell you the time before we start.
I changed the filter but the water is still slow — what could be causing it?
The sediment filter is not the only cause. The pre-charge pressure of the storage tank may have dropped, the membrane may be blocked, or the feed pressure may be inadequate. On a unit without a pump, flow falls noticeably once mains pressure drops below 2.5 bar. To find the real cause, the air pressure of the tank and the inlet pressure are measured together.
Can I have my unit removed and refitted at a new address?
Yes. Removal and installation at the new address are part of the service. At the new home the suitability of the plumbing (tap hole, drain connection, distance to a socket) is assessed on site. If the filters have reached the end of their life during the move, they can be changed on the same visit.

Does your unit need servicing?
Choose your district and leave a photo of your unit; we will see whether our filters fit and get back to you. The stage to be changed is established by a measurement on site.
