The process is very easy for installing different types of water filters at home. Learn every installation step to get yourself rid of the dependency on professional support.

Why waste time and money on the services of others when you can install the water purifier yourself in a few simple steps? Read on to understand the process of installing water filtration systems at home.

Unpacking the Water Purifier

Installing a water purifier involves three main steps but before understanding those steps, first unpack the water purifier to ensure the availability of all the necessary components. Use a knife or a cutter to slit the water purifier pack and remove the main body. After opening the box, carefully check the body of the water purifier and the supplied components. Generally, a water purifier comes with:

  • 3-way connector
  • SS Ball Valve
  • Food grade white pipe 3/8” – 3 meters
  • Food grade pipe ¼” (white and blue) – 3 meters each
  • Screws and plastic inserts – 2 each
  • Water filter manual
  • Drilling sticker

Besides the above necessary components, you need to keep a pipe wrench, screwdriver, drilling machine and Teflon tape ready.

The three main steps can be divided into:

1.       Plumbing

2.       Mounting the water purifier

3.       Connecting water purifier to water supply line and testing TDS

Step – 1 Plumbing

Since water purifiers are becoming an essential commodity nowadays, plumbers generally install a separate line for installing the water purifying systems. However, if no separate connection is provided for water purifiers in the kitchen, you can fix the inlet on kitchen tap. For fixing the inlet on the kitchen tap, follow these steps:

  • First turn off the main water supply line and remove the tap with the help of an adjustable wrench;
  • Fix the 3-way connector to the water outlet in the wall. Use a Teflon tape on the thread of 3-way connector to prevent leakage;
  • Install the tap back (connect it with the other end of the 3-way connector). Use Teflon tape on the thread of the tap to prevent leakage;

Connect the ball valve with the threaded port on the body of the 3-way connector. Remember to use Teflon tape on the threaded end of ball valve to ensure a leakage-free joint;

  • Take the white pipe and broaden one of its ends with the help of a screwdriver. Remove the hex nut affixed to the ball valve and insert white pipe inside the nut. Fix the broadened white pipe end to the nipple of the ball valve so that it completely slips over the opening of the nipple;
  • Tighten the hex nut securely (in which the white pipe was inserted) to the threaded end of the ball valve. Use an adjustable wrench to tighten the hex nut so as to lock the pipe firmly to the nipple of the ball valve;
  • The lever on the ball valve in perpendicular position indicates that the water supply is “Off”, and in parallel position denotes that the water supply is “On”.

Step -3 Mounting the Water Purifier

Most of the water purifiers come with a drilling sticker. This helps in mounting the water purifier in a horizontal upright position. For making holes for screws, you need a drilling machine. In most cases, an 8mm drill bit is needed for drilling the wall. Before starting to drill ensure proper leveling on the wall with the help of the drilling sticker. Follow these steps:

  • Put the sticker on the wall in a perfectly horizontal position and drill on the slots marked on the sticker;
  • Remove the drilling machine and push plastic inserts properly in the drilled holes using a hammer;
  • Insert self-tapping screws in both the holes with the help of a screwdriver.

Step – 4 Installing and connecting the purifier

After removing the water purifier from the box, keep it on a flat surface. Remove the strap wires on the different types of filter membranes. The wires are tied around the filter to provide them protection during shipment. Follow these steps:

  • Mount the water purifier by fixing the designated round slots on the back end of purifiers to the screws affixed to the wall;
  • Remove the dead plugs from the water inlet hose in the purifier and insert the loose end of white pipe (which is connected to the tap) inside the inlet;
  • Again, remove the dead plug from outlet or rejected water hose and insert the blue pipe to the waste water outlet, which is also called the “flow restrictor outlet” and direct the other end of the blue pipe to the drain;
  • To eliminate any possibility of pipe snapping, clamp both the pipes to the wall;
  • While mounting the water purifier, make sure that the outlet water pipe is below the level of inlet water pipe otherwise the rejected water will reverse back into water purifier;

Once the white and blue pipes are fixed, plug in the power cable into the electrical socket and switch it on.

Your water purifier is ready to operate and provide you with clean and healthy water.

Another important step is checking the TDS (total dissolved impurities) in water. Most of the modern designs of water purifiers come with a screw-type button to regulate the TDS level. A small hand-held TDS meter is used to check the TDS level in water. You can simply immerse the measuring end of the meter into the purified water and check the reading on the digital display. If the TDS level is not appropriate, you can re-adjust it with the TDS controlling button on the water purifier.


It is advised that you drain out the first few liters of the RO+UV+UF water purifiers as the water is not suitable for drinking. To conserve water, it is also advised that you store the rejected water in a container for secondary usage, such as cleaning floors, watering plants, or washing cars.
