Reverse osmosis is a water filtration device that is installed for home use. The system is most often installed under a sink. But if there is not enough space, Reverse Osmosis can be placed anywhere within a 10 m radius of the sink. It will do its job steadily in both cases. Almost always water filter installation can be difficult. Not everything is prescribed in the system manual, and it is difficult for a person who first encounters such equipment to do everything correctly. With this article, it will be much easier to understand.

Preparing to install a filtration system 

The necessary tools should be stocked up in advance. Specifically: 

  • The knife is sharp, it’s better if it’s clerical; 
  • one or two adjustable wrenches to three-quarters; 
  • sealing thread or tape; 
  • a tool for piercing holes; 
  • 7 mm, 10 mm, 12 mm drills.

Sometimes additional tools are needed to make the filter work as efficiently as possible. If in doubt whether the water pressure is high enough, use a manometer. If the head is below 3.5 bar, reverse osmosis will not work properly. To know exactly which filters are required on a case-by-case basis, you can use a TDS water analysis tool.

Setting Reverse Osmosis

An introductory sheet to the device tells you how to do everything correctly. And in conjunction with this article you will have all the necessary information for installation, including the order of installation of reverse osmosis filters and other, no less important processes. The first task – find a place where the system of filtration of drinking water will stand. The area under the sink will require a container (pelvis or something similar) and a towel that absorbs moisture well. At this stage, it is important to check for leaks. For this purpose, the air is vented by opening a conventional tap. When you see that the water is already bubble-free, stop feeding it.

A drain clamp is installed on the siphon to divert non-drinking water into the waste. It is recommended to place it above the water trap. It is a special device that prevents the smell of impurities from seeping into the drain. It is often performed like a curved pipe. Here you will need a drill and a 7 mm drill. A drill hole is needed for the propylene pipe. You need to be particularly careful when drilling as you can punch the siphon through. Do not forget that the seal must be glued into the clamp. It is included in the set. Then you need to put a nut on the propylene tube and extend the tube to the front of the siphon. The tube should enter by 5 or 10 cm. The main task here is to make sure that the tube is bent and not close to the wall of the siphon. This way, you will ensure a minimum level of audibility of the water murmuring. Bend the tube inside the siphon, attach the other part of the drain clamp, and tighten the screws. Be careful when doing this, there is a risk of bending the trap.

To place the diaphragm, you will need to find a two-piece housing on a metal bracket. It lies on a horizontal plane, fixed with plastic brackets. Disconnect the hose and fitting and disconnect the housing on the right where the cover is. The next step is to unscrew the cover and install the membrane element. The diaphragm is placed in the depths with the rod with rubber bands for sealing forward. For it to enter correctly in the intended place, it is necessary to create pressure on it very carefully, it is better to do it by hand.

After the diaphragm is installed, the cartridges in the lower pre-cleaning row should be taken care of. They should be placed in the cartridges intended for this purpose, it is easy, they are most often symmetrical. When twisting, make sure that the case is close to the rubber band. It is easy to attach a container with cleaned water to the whole system. A sealing thread should be placed on the thread. And screw the tank faucet onto it.
