Under-sink water filters offer a convenient and effective way to improve your tap water quality. They remove contaminants like chlorine, lead, and sediment, resulting in cleaner, better-tasting drinking water. But how to install under sink water filter yourself?
In this guide, Best Reverse Osmosis Drinking Water System will break down the process into easy-to-follow instructions, so you can enjoy clean, filtered water in no time. From gathering the necessary tools to making the final connections, this guide will ensure a smooth and successful installation.
Before You Begin
Before you start with your installation, there are some considerations you need to bear in mind:
Choosing the Right Filter System
The first step is selecting the appropriate under-sink filter system for your needs. Different filters address specific contaminants. Common types include:
- Reverse Osmosis (RO): Removes a wide range of contaminants, including dissolved solids and minerals (around $300-$800+).
- Carbon Block: Effective for chlorine, taste, and odor improvement (around $100-$300).
- Sediment Filters: Primarily remove larger particles like dirt and rust (around $50-$100).
You can consider your local water quality report or conduct a simple home test to identify the contaminants you want to target. Ensure the chosen filter system fits comfortably under your sink with enough space for filter replacements.
Gather the Tools
For a smooth installation, have the following tools on hand:
- Adjustable wrench
- Phillips and slotted screwdrivers
- Bucket
- Plumber’s tape
- Tubing cutter (optional, for some filter systems)
- Electric drill (if installing a new faucet)
How to Install Under Sink Water Filter?
Once you have had all the necessary tools on hand, let’s get into the interesting installation process.
Step 1: Turning Off the Water Supply
- Safety First: Before starting, ensure the water supply is turned off to prevent any mess or accidents.
- Locate the Shut-Off Valve: Find the shut-off valve for the cold water line under your sink. This valve is usually a handle or knob.
- Turn Off the Valve: Rotate the valve clockwise until it is fully closed. You can verify that the water is off by turning on the cold water faucet and checking that no water flows out.
Step 2: Disconnecting the Cold Water Line
- Prepare for Water Drips: Place a bucket or a pan under the connection point to catch any residual water that may drip when you disconnect the line.
- Loosen the Nut: Use an adjustable wrench to loosen the nut connecting the cold water line to the existing faucet. Turn the nut counterclockwise.
- Detach the Line: Carefully remove the cold water line from the faucet, ensuring minimal water spillage.
Step 3: Installing the T-Adapter
- Prepare the T-Adapter: Take the T-adapter (included with your RO system) and wrap its threads with several layers of plumber’s tape. Wrap the tape in a clockwise direction to ensure a tight seal.
- Attach the T-Adapter: Screw the T-adapter onto the cold water shut-off valve. Use the adjustable wrench to tighten it securely, but avoid over-tightening, which could damage the valve.
Step 4: Connecting the Feed Line
- Attach the Feed Line: Connect one end of the feed line (provided with your RO system) to the open port of the T-adapter. Secure it by tightening the connection with the wrench.
- Cutting the Feed Line (if necessary): If the feed line is too long, use a tubing cutter to trim it to the required length. Ensure the cut is clean and square to prevent leaks.
Step 5: Installing the Filter Faucet (if applicable)
- Drill a Hole: If your RO system includes a separate faucet for filtered water, drill a hole in the countertop according to the size and placement specified in the system’s instructions.
- Install the Faucet: Insert the faucet body through the drilled hole. Secure it in place with the mounting hardware provided.
- Connect the Faucet: Attach the filter’s output line to the new faucet, following the manufacturer’s instructions carefully to ensure a proper connection.
Step 6: Mounting the Filter Unit
- Choose a Location: Find a suitable spot under the sink where there is enough space to mount the filter unit and perform future filter changes.
- Mount the Unit: Use the provided brackets or straps to secure the filter unit to the cabinet wall or floor. Make sure it is mounted firmly to prevent any movement or vibration.
Step 7: Connecting the Filter System
- Connect the Feed Line: Attach the remaining end of the feed line to the inlet port of the filter unit. Tighten the connection securely to avoid leaks.
- Connect the Outlet Line: Connect the filter’s outlet line to the new faucet or, if the system does not have a dedicated faucet, to the existing cold water line. Follow the instructions provided with your system to ensure a proper connection.
However, before starting the installation, it’s important to determine whether a reverse osmosis system is the right choice for you and why it should be placed under the sink. Installing the system under the sink not only optimizes its performance but also offers several benefits.
Final Touches and Leak Check
Now that the connections are made, it’s time to ensure everything is secure and working properly. Here’s what to do:
- Turning Water Supply Back On: Locate the shut-off valve (usually under the sink or on the main water line) and slowly turn it back on in a clockwise direction. Open the faucet handle you connected to the filter to allow water to flow.
- Checking for Leaks: Grab a paper towel or rag and carefully inspect all the connection points. Look for any signs of dripping around the filter housing, the adapter to the shut-off valve, the faucet connections, and any tubing connections.
- Tightening Loose Connections: Simply turn off the faucet handle and then the shut-off valve again. Use your wrench to carefully tighten the loose connection. Once tightened, repeat steps 1 and 2 to turn the water back on and check for leaks again.
Pro Tip: It’s a good idea to place a towel or pan under the filter and connections during this process to catch any drips while checking for leaks.
