Installing a reverse osmosis drinking water filter

• We connect the filtering station to the water supply and sewerage system

In urban apartments, the water flowing from the tap, as a rule, is not suitable for drinking without first boiling. You can solve the problem of dirty water in different ways, but the most optimal, perhaps, would be the installation of a flow-through filter with reverse osmosis.

The well-known filter jugs are no doubt good, but not convenient enough. Every time you need clean drinking water, you must wait until it filters through the filter element. Naturally, we would like to negate the waiting time, thereby significantly speeding up and simplifying the cleaning process. Flow filters do an excellent job with these functions..

The existing filters differ in the number of filter elements and the presence or absence of a reverse osmosis system. Two-three-stage filters already make it possible to obtain drinking water from tap water, but it will become absolutely pure only after passing through the osmosis membrane. Passing through the preliminary filter elements, the water is freed from 95% of impurities. The osmosis membrane with micro-holes 0.0001 microns in diameter allows only water molecules to pass through, trapping everything else, including pathogens and bacteria. To prevent blockage of the holes, the membrane is constantly washed and part of the water after filtration goes into the sewer. This, of course, slightly increases the water consumption compared to traditional cleaning methods by filtration through carbon filters, but the result is worth it..

So, if you are tired of the endless process of decanting water in a filter jug ​​or you are tired of carrying heavy bottles from a spring or the nearest supermarket, which also end at the most inopportune moment, then it makes sense to think about installing a multi-stage filter. Which one to take, with reverse osmosis to get practically distilled water, or without it – it’s up to you, and we will tell you how to install and connect such a filter to the water supply.

Filter assembly

Externally, the filtering station with reverse osmosis differs from the versions without it by the presence of an additional flask above the glasses with mechanical filters. The connection procedure is practically the same in both cases, with the exception of the need to connect the drain pipe from the osmosis.

Let’s start assembling.

1. Unscrew three plastic flasks with a special plastic wrench from the set.

They must have rubber O-rings inside to ensure tightness

2. Insert our filter element into each flask, and screwing the flasks back, tighten it with the same wrench. You should pay attention to which side the water intake is taking place – there will be the first filter element – a coarse filter, and from which conclusion – there the last one, as a rule, is coal.

3. In the upper, horizontal flask, smaller in size, insert the filter membrane with the nose with elastic bands in front, and also tighten the lid tightly.

Assembly of the filter station is completed.

Installation of a water tap

1. We drill a hole with a 12 mm drill at the place where the faucet is installed. If it is difficult to do it right away, then you can first drill with a small drill, for example, 4 mm, and then drill the hole to the desired size.

2. Put a decorative stainless washer and a rubber seal on the tap thread. We install in the hole. From below under the sink we put on a thick washer, an engraving ring and press everything tightly with the nut that comes with the kit.

We connect the filtering station to the water supply and sewerage system

For reverse osmosis filters, it is necessary to equip a drain to the sewer. Otherwise, skip the next steps from the first to the fourth.

1. We apply a tie-in clamp to the siphon pipe. We mark the place for the drain hole and make it with a 7 mm drill.

2. Apply a foam rubber pad so that the holes on the pad and in the siphon match.

3. We squeeze the cover on the siphon with the halves of the clamp. We fasten them with the bolts included in the kit.

4. If necessary, for example, if there is a drainage outlet for the washing machine, you will need to slightly sharpen the counterpart of the clamp.

5. We screw two self-tapping screws with a large head into the place where the cleaning system will hang.

6. We hang the filter station.

7. Connect the supplied adapter and ball valve to the cold water pipe. We install them using a fum tape, not forgetting to close the cold water inlet valve.

8. Connect the hoses. First, we unscrew the nut from the tap, put it on the water supply hose, put the hose itself on the “nipple” of the tap.

9. Tighten the nut.

10. On the outlet hose we put on the nut from the tap, then the plastic washer-seal, and in the hose we insert the plastic plug with a hole – everything from the kit.

11. Insert the plastic tube into the tap thread and tighten with a nut.

12. We connect the drain hose to the inset on the siphon and fix it with a retaining ring.

13. If the system has a reserve tank, then connect it too. On the spout of the reserve tank on the fum tape, screw on the plastic tap, insert the tube and fix it with a retaining ring.

14. It remains to flush the system. If the station is without reverse osmosis, then you just need to open the tap and drain the water for 10-15 minutes. If osmosis is installed, then open the water supply, remove the hose from the third flask and rinse the filters for 10-15 minutes. You can simply remove the entire system and drain the water into the sink.

15. Putting everything back and using clean drinking water.
