Reverse osmosis (RO) is one of the most effective technologies for removing water contaminants and purifying drinking water. While systems vary, proper installation is crucial to achieve clean, healthy water for your household.

In this guide, we’ll walk you through a complete DIY reverse osmosis system installation, using the industry-leading iSpring RCC7AK as an example model. We’ll cover:

How Does Reverse Osmosis Work?

To understand RO system setup, it helps to first learn what this technology actually does. Reverse osmosis utilizes a multi-step process to reduce contaminants:

1. Water Flows Through a Prefilter

Tap water enters and flows through a sediment prefilter to trap particles like silt, rust and sand. This protects later filters.

2. The RO Membrane Filters Out Contaminants

The filtered water then enters the RO membrane. This is the heart of the system – it removes up to 99% of contaminants by allowing only water molecules to pass through its microscopic pores.

3. Purified Water Flows To Storage

The freshly purified water exits the RO module and flows to a storage tank. Now free of contaminants, it is ready for drinking and cooking use.

4. The Rest Flows to Drain

Water that does not pass through the RO membrane exits as a concentrated stream, carrying removed substances down the drain.

Now that you understand how reverse osmosis systems function, let’s look at what components make up a complete installation.

What’s Included in the iSpring RCC7AK RO System

The iSpring RCC7AK is a premium 5-stage reverse osmosis system. Here are the components included:

With all cartridges pre-loaded in the housing pods and the faucet already built, the system arrives ready for installation right out of the box.

Where to Install the RO System Components

Proper placement of the reverse osmosis system ensures optimal performance and space utilization in your home. Here are the recommended locations for each component:

Locate parts close together to minimize tubing runs. Now let’s look at the installation sequence.

Step-By-Step RO System Installation

Follow these steps to properly install your iSpring reverse osmosis system:

Step 1 – Mount Components

First, mount the filter housings and storage tank. Typical mounting options:

Under Sink Mount:

Basement Shelf Mount:

Tip: Allow space underneath to change filters and for tubing runs.

Step 2 – Install Faucet

Select your desired faucet location. Common choices:

In your chosen spot:

Don’t attach tubing yet – this comes later.

Step 3 – Mount Drain Saddle Valve

The drain saddle valve drains away concentrated waste water from the RO. To install:

Step 4 – Connect Water Supply

Now it’s time to connect the water supply line using the feed water adapter:

Step 5 – Link System Components

The final step is connecting the integrated tubing between the RO components:

With all parts installed and connected by tubing, your RO system is ready to use!

Getting the Most From Your RO System

Once installed, just a bit of maintenance keeps your reverse osmosis system running optimally:

Following the manufacturer’s maintenance schedule keeps the system performing like new for years of reliable use.

FAQs About RO Installation

Here are answers to some commonly asked questions about reverse osmosis system setup:

Where is the best place to install the faucet?

Most often, directly on the sink top or using an existing soap dispenser hole. Under counter and countertop options are also available.

How do I ensure watertight tubing connections?

Carefully insert tubing fully into ports, then firmly hand tighten compression nuts until snug. Use wrench for final 1/4 turn. Don’t overtighten.

What tools do I need for installation?

Usually just an adjustable wrench, utility knife, screwdriver, and drill with 1/2″ bit. Plumbers putty if drilling a new faucet hole.

What if my tubing is too short?

Extension tubing can be purchased to lengthen the runs as needed. Cut and use connectors to integrate seamlessly.

How often should I change the RO membrane?

For optimal contaminant reduction and purified water flow, replace the RO membrane every 2-3 years. Annual testing helps confirm it’s performing properly.

Is professional installation available?

Absolutely. Our team of water quality experts can handle the entire installation for you. Contact us for pricing details.

How much water pressure is required?

40-60 psi is the recommended minimum to effectively run an RO system. A booster pump can be added if pressure is consistently lower.
