How to Install a Water Softener Using a Softener Loop
If your Arizona home already has a water softener loop, you’re one step ahead. A softener loop makes installing a water softener much easier and can save homeowners hundreds – or even thousands – of dollars compared to adding one later.
In this video, the team at Young Plumbing walks through the basic process of installing a water softener on an existing softener loop. While water softener installation should always be performed by an experienced plumber to ensure everything is connected correctly and leak-free, understanding the process can help you know what to expect.

What Is a Water Softener Loop?
A water softener loop is a dedicated plumbing connection that builders often install during construction. It provides three important connections:
- Water inlet – Brings hard water into the softener.
- Water outlet – Returns softened water back into your home’s plumbing system.
- Drain line – Carries wastewater away during the softener’s regeneration cycle.
If your home already has a softener loop, installing a water softener is typically much simpler than modifying your plumbing system to add one.
Step 1: Disconnect the Existing Softener Loop
The installation begins by shutting off the water supply and cutting out the existing loop connections. Once removed, you’ll have access to the:
- Inlet line
- Outlet line
- Drain line
The drain line is typically a smaller pipe because it only carries wastewater generated during the softener’s cleaning cycle.
Step 2: Install the Proper Fittings
After preparing the pipe, new threaded fittings are installed so the water softener can be connected securely. In this installation, the plumbing was completed using a press system, although soldered copper connections can also be used depending on the application.
The drain connection also receives the proper PEX adapter to connect the softener’s drain tubing safely.
Step 3: Install the Control Valve
The water softener’s control valve (sometimes called the Clack valve) is then attached.
One important tip from the installation: Only hand-tighten the control valve connections.
Using channel-lock pliers or overtightening these fittings can damage the threads or seals, potentially causing leaks.
Step 4: Adjust the Plumbing for Proper Fit
Every installation is a little different. In this case, the water softener sat slightly closer to the wall than expected, so additional fittings – including street 90-degree elbows and threaded adapters – were used to create the proper spacing.
Taking the time to properly align the plumbing helps:
- Reduce stress on the fittings
- Prevent leaks
- Create a cleaner-looking installation
- Make future maintenance easier
Step 5: Connect the Flexible Water Lines
Flexible stainless steel connectors make attaching the inlet and outlet much easier. These connections are first tightened by hand before being snugged into place.
Once everything is aligned correctly, the plumbing connections can be permanently secured.
Step 6: Connect the Drain Lines
Most residential water softeners require a drain connection for regeneration. The tandem unit shown in this installation requires two drain lines, both of which are connected to the home’s existing drain system.
Proper drain installation is essential to ensure the water softener operates efficiently and meets plumbing code requirements.
Why Water Softeners Are So Important in Arizona
Arizona has some of the hardest water in the country. Hard water contains high levels of calcium and magnesium that can build up inside your plumbing system and appliances over time.
Installing a quality water softener offers several benefits, including:
- Reduced mineral buildup inside pipes
- Longer life for water heaters and plumbing fixtures
- Softer skin and hair after bathing
- Cleaner dishes with fewer water spots
- Brighter laundry
- Improved efficiency for water-using appliances
For many Arizona homeowners, a water softener is one of the best investments they can make to protect their home’s plumbing.
