Introduction
If you’re concerned about the quality of the water that comes out of your sink, you may want to consider installing an under sink water purifier system. While there are many different types of water purifiers available, an under sink system can be a relatively easy and affordable option that provides you with clean, safe drinking water.
Materials Needed
- Under sink water purifier system
- Adjustable wrench
- Drill
- Hole saw
- Teflon tape
- Bucket
Step 1: Turn off the Water Supply
Before you begin installing the under sink water purifier system, you’ll need to turn off the water supply to your sink. Locate the shut-off valve under your sink and turn it to the off position. If you’re having trouble finding the shut-off valve, you may need to turn off the water supply to your entire home.
Step 2: Install the Purifier Unit
Next, you’ll need to install the purifier unit under your sink. The specific instructions for this step will depend on the type of under sink water purifier system you’ve purchased, so be sure to read the manufacturer’s instructions carefully.
Step 3: Drill a Hole
Once the purifier unit is installed, you’ll need to drill a hole through your sink or countertop to allow the purified water to flow through. To do this, mark the location where you want the hole to be and use a hole saw to drill through the sink or countertop. Make sure to drill a hole that is the right size for the faucet that came with your water purifier system.
Step 4: Attach the Faucet
After you’ve drilled the hole, you’ll need to attach the faucet that came with your water purifier system to your sink or countertop. Again, the specific instructions for this step will depend on the type of system you have, so be sure to follow the manufacturer’s instructions carefully.
Step 5: Connect the Hoses
Next, you’ll need to connect the hoses from the purifier unit to the faucet and to the shut-off valve under your sink. Use an adjustable wrench to securely tighten all of the connections, and use Teflon tape to create a watertight seal.
Step 6: Test the System
Once you’ve connected everything, it’s time to test the system. Turn the water supply back on and let the water flow through the system for a few minutes to flush out any air or debris. Then, turn on the faucet and check the water flow and taste to make sure everything is working properly.
Conclusion
Installing an under sink water purifier system can be a great way to ensure that you and your family are drinking clean, safe water. While the process may seem intimidating at first, following the manufacturer’s instructions carefully and taking the time to properly connect all of the hoses and components can make it a relatively simple DIY project.
