Water purifiers can ensure the safety of the water produced and remove harmful substances from drinking water, making their function very significant. Now, let’s take a look at how to install a faucet water purifier for home use.

How to Install a Home Faucet Water Purifier

1. Install the Purifier Accessories

Before installation, carefully check if all the accessories are complete, as faucet water purifiers require many components. If any parts are missing, it will affect the installation. Pay attention to see if there are any lost or damaged pipes, connectors, or faucet components, and assemble the accessories first. Some products require a specialized faucet, such as a reverse osmosis (RO) system, which typically uses a goose-neck faucet that is installed on the kitchen countertop and requires drilling.

2. Install the Purifier Main Unit

Next, start installing the main unit of the water purifier. This step is crucial as it relates to daily use. Open the packaging of the main unit to find two black "O" rings. Insert one end into the RO membrane tubing, ensuring it reaches the bottom, and then tighten the cap of the RO membrane. Next, disconnect the water inlet pipe of the RO membrane and place it in a container. Turn on the water supply to fill the pre-filter housing with water, then reconnect the previously detached RO membrane inlet pipe.

3. Connect the Inlet T-Connector

After the main unit is installed, the next step is to install the inlet T-connector. First, turn off the mains water supply. Wrap the threads of the ball valve with sealing tape a few times, then connect the PE pipe to the side hole of the inlet T-connector and the outlet of the ball valve.

4. Connect the Inlet, Outlet, and Drainage Ports

Next, cut the PE pipe, and after installing the T-connector, connect it to the inlet port of the main purifier unit. Additionally, connect the PE pipe to the outlet port.

5. Test Water Output

Finally, after installing the water purifier, turn on the faucet and carefully check for any leaks or issues with low water flow. If there are any problems during use, they need to be addressed promptly.

In summary, the above is about how to install a faucet water purifier for home use. I believe everyone understands now! It is important to master the installation method; if you are unsure about the installation process, it is best to ask a professional for assistance.
