DIY or Pro: Understanding the Installation Process of an Under Sink RO Water Filter

2024-06-12

Installing an Under Sink Reverse Osmosis (RO) Water Filter can significantly improve the quality of your drinking water, offering a reliable solution for removing impurities and contaminants. While the benefits of such a system are clear, many homeowners wonder about the complexity of the installation process and whether it's feasible to undertake as a DIY project. This blog delves into the installation process of an Under Sink RO Water Filter and evaluates whether homeowners should consider professional installation.

Installation Process Overview

1. Preparation and Gathering Tools:

- Tools Required: Adjustable wrench, screwdriver, utility knife, drill (optional for some installations), Teflon tape.

- Components Included: RO unit, pre-filters (sediment and carbon filters), RO membrane, post-filter, storage tank, faucet, tubing, and various fittings.

- Preparation Steps: Clear the space under the sink, turn off the cold water supply, and gather all necessary tools and components.

2. Installing the Faucet:

- Drilling a Hole (if needed): Some sinks may already have a hole for the RO faucet. If not, drilling might be required.

- Mounting the Faucet: Insert the faucet stem into the hole, secure it with the provided hardware, and attach the tubing that will connect to the RO unit.

3. Installing the Feed Water Adapter:

- Shutting Off Water Supply: Turn off the cold water valve and disconnect the supply line from the valve.

- Attaching the Adapter: Install the feed water adapter between the cold water valve and the supply line, ensuring a tight fit to prevent leaks.

4. Mounting the RO Unit:

- Selecting a Location: Mount the RO unit on the wall of the cabinet under the sink, ensuring easy access for future maintenance.

- Securing the Unit: Use screws or brackets provided to secure the unit firmly in place.

5. Connecting the Tubing:

- Color-Coded Tubing: RO systems typically use color-coded tubing for ease of installation.

- Connecting to Water Source: Connect the tubing from the feed water adapter to the inlet of the RO unit.

- Connecting the Drain Line: Attach the drain line tubing to the RO unit and insert it into the sink’s drain pipe using the provided saddle clamp.

- Connecting the Storage Tank: Attach the tubing from the RO unit to the storage tank, ensuring the tank valve is open.

- Connecting to the Faucet: Finally, connect the tubing from the RO unit to the newly installed faucet.

6. Initial System Flush:

- Flushing the Filters: Turn on the water supply and allow the system to flush for a specified period, usually around 2 hours, to clear any impurities or debris from the new filters.

- Checking for Leaks: Inspect all connections and joints for any signs of leakage, tightening as necessary.

DIY vs. Professional Installation

DIY Installation:

- Advantages:

 - Cost Savings: Installing the system yourself can save the cost of professional installation.

 - Satisfaction: Completing the project on your own can be rewarding and provide a sense of accomplishment.

- Considerations:

 - Skill Level: Basic plumbing skills and familiarity with tools are essential.

 - Time: The installation can take several hours, especially for first-timers.

Professional Installation:

- Advantages:

 - Expertise: Professionals have the experience to handle potential issues and ensure a leak-free installation.

 - Warranty Protection: Some manufacturers may require professional installation to maintain the warranty.

 - Convenience: Saves time and effort, ensuring the system is installed correctly and efficiently.

- Considerations:

 - Cost: Professional installation adds to the initial investment but can prevent costly mistakes.

Conclusion

Installing an Under Sink RO Water Filter is a manageable task for those with basic plumbing skills and the right tools. The process involves several steps, from preparing the installation site to connecting the system's various components and ensuring a proper flush. While many homeowners successfully undertake this as a DIY project, those who prefer convenience or lack confidence in their plumbing abilities may find professional installation worthwhile. Regardless of the approach, a properly installed RO system offers significant benefits in providing clean, safe, and great-tasting water.
