Other useful items include a bucket, rags, work gloves, and a flashlight.

Understanding Your Water Lines and Plumbing

A clear understanding of your home’s plumbing system is essential.

Take the time to:

• Locate the Main Water Line: This is where the water enters your home. Knowing its location is crucial for shutting off the water supply before you begin.

• Identify the Cold Water Supply Line: The water softener needs to be connected to the cold water supply line. This is usually the line that feeds your water heater.

• Understand the Location of the Drain Line: The water softener will require a drain line for regeneration. Determine where you’ll connect the drain line. Most Rheem water softeners use a standard threaded connection, so matching it to a nearby drain line is a good practice.

Testing Your Water

Before installing a water softener, it’s important to quantify the water’s level of hardness to help you adjust the system’s setting and evaluate the water softener’s performance after installation.

• Use a Water Hardness Testing Kit: These kits are readily available at most hardware stores. Follow the instructions carefully to determine the level of hardness in your water, usually measured in grains per gallon (GPG) or parts per million (PPM).

Checking Local Plumbing Codes

Adhering to local plumbing codes is essential for ensuring a safe and legal installation. Plumbing codes vary by region and are in place to protect public health and safety.

Contact your local building department or plumbing inspector to obtain information on the specific codes in your area.

Checking Water Pressure and Electrical Outlet

• Water Pressure: The water pressure in your home must be within the acceptable range for the Rheem water softener to function correctly. This range is typically specified in the user manual.

  • If your water pressure is too high, you may need to install a pressure regulator. If it is too low, consider a booster pump if feasible for your plumbing system and water softener.

• Electrical Outlet: The Rheem water softener requires a nearby electrical outlet to power its control valve. Ensure that a properly grounded outlet is located within reach of the softener’s power cord. If an outlet is not readily available, you may need to have one installed by a qualified electrician. Never use extension cords as a permanent solution.

Step 2: Installing Your Rheem Water Softener – A Step-by-Step Guide

With the preliminary preparations complete, it’s time to move on to the core of the project: installing your Rheem water softener. This requires careful attention to detail and adherence to the steps outlined below. Rushing this process can lead to leaks, malfunctions, or even damage to your plumbing system.

Shutting Off the Water Supply

The first and most critical step is to shut off the main water supply to your home. This prevents water from flowing through the pipes while you are working, avoiding potential flooding and water damage.

Locate the main water shut-off valve, usually found near the water meter or where the main water line enters your house. Turn the valve clockwise until it is completely closed.

After shutting off the main water supply, open a faucet at the lowest point in your home (e.g., a basement faucet or an outdoor spigot). This will relieve any residual pressure in the pipes and prevent water from spraying when you cut into the water lines. Let the water drain completely before proceeding.

Installing the Bypass Valve

The bypass valve is a crucial component that allows you to isolate the water softener for maintenance or repairs without interrupting the water supply to your entire home.

Most Rheem water softeners come with a bypass valve, either pre-installed or as a separate unit that needs to be attached. Consult your user manual for specific instructions for your model.

Generally, the bypass valve is installed before the water softener, on the incoming and outgoing water lines. This valve typically has three positions: "Service" (normal operation), "Bypass" (water softener is isolated), and "Shut-off" (completely shuts off water flow).

Follow the manufacturer’s instructions to connect the bypass valve to the inlet and outlet ports of the water softener unit. Use Teflon tape or pipe dope on all threaded connections to ensure a watertight seal. Tighten the connections securely, but avoid over-tightening, which can damage the valve.

Connecting the Water Lines

Cutting and Preparing the Water Lines

Carefully measure the distance between the bypass valve connections and the existing water lines. Use your pipe cutter to cut the water lines to the correct length. Ensure the cuts are clean and straight for proper connections.

Deburr the cut ends of the pipes to remove any sharp edges or burrs that could damage the fittings or create leaks. Use a deburring tool or sandpaper for this purpose.

Using Fittings to Connect the Water Lines to the Softener

Select the appropriate fittings (e.g., compression fittings, threaded fittings, or push-fit connectors) based on your plumbing system and the type of connections on the bypass valve.

Apply Teflon tape or pipe dope to the threads of any threaded fittings. Carefully tighten the fittings onto the water lines and the bypass valve connections. Again, avoid over-tightening.

If using compression fittings, ensure the compression nut is properly tightened to create a secure and leak-free seal. Follow the fitting manufacturer’s instructions.

Connecting the Drain Line

The drain line is used to discharge water during the regeneration cycle of the water softener.

Attach the drain line to the drain connection on the water softener. The drain line should be made of flexible tubing that is compatible with your local plumbing codes.

Run the drain line to a suitable drain location, such as a floor drain, laundry sink, or standpipe. Ensure the drain line is securely attached to the drain to prevent it from coming loose and causing water damage.

Maintain an air gap between the end of the drain line and the drain opening to prevent backflow. This prevents contaminated water from being siphoned back into the water softener.

Preparing the Salt Tank/Brine Tank

The salt tank, also known as the brine tank, is where the salt (sodium chloride or potassium chloride) is stored. The salt is used to create the brine solution that regenerates the resin beads in the water softener.

Carefully pour the appropriate type of salt (refer to your Rheem water softener manual for recommendations) into the salt tank. Fill the tank to approximately one-third to one-half full.

Do not overfill the salt tank, as this can cause salt bridging, which can prevent the water softener from functioning properly.

After adding the salt, add a few gallons of water to the salt tank to help dissolve the salt and create the brine solution.

Connecting the Power Supply

Most Rheem water softeners require a standard 120V electrical outlet to power the control valve and other electronic components.

Locate the power cord on the water softener and plug it into a nearby electrical outlet. Ensure the outlet is properly grounded.

Never use an extension cord to connect the water softener to the power supply. This can create a fire hazard.

Keep the power cord away from water and other potential hazards.
If the outlet is not GFCI protected consider getting one installed by an electrician.

Step 3: Setting Up and Starting Your Rheem Water Softener

With the plumbing connections finalized, the next critical step is configuring your Rheem water softener for optimal performance. This involves programming the timer/control valve and initiating the system. Accurate programming is vital to ensure efficient water softening and prevent unnecessary salt usage. Remember, the specific settings will vary depending on your water hardness and water usage, so consulting your Rheem water softener’s user manual is essential throughout this process.

Understanding the Timer/Control Valve

The timer/control valve is the “brain” of your water softener.

It dictates when the system regenerates (cleans the resin beads that soften the water) and how much salt and water are used during the regeneration process. Rheem water softeners typically feature an electronic control valve with a digital display and buttons for navigation. Familiarize yourself with the layout and functions before attempting to program it.

Programming the Control Valve: A Step-by-Step Guide

The specific steps for programming your Rheem water softener will vary depending on the model. However, the general principles remain the same. Here’s a typical workflow:

1. Initial Power Up: Once you plug in the softener, the display will likely illuminate and may prompt you to set the time of day. Use the up/down arrow buttons to adjust the hour and minute, and then press the "Set" or "Confirm" button to save the settings.

2. Setting Water Hardness: This is the most critical parameter. Use the water hardness test results obtained in Step 1 to input the appropriate value. The hardness is typically measured in grains per gallon (GPG) or parts per million (PPM). Consult your user manual for how to input this data correctly. Entering an inaccurate hardness level will result in either inefficient softening or excessive salt consumption.

3. Setting Regeneration Frequency: Most Rheem water softeners offer different regeneration modes. You might have the option to set the regeneration frequency based on a timer (e.g., every two days) or based on water usage. A metered regeneration mode is often more efficient, as it regenerates only when necessary based on your actual water consumption. If available, input your household’s average daily water usage (you can estimate this or use your water bill as a reference). The control valve will then calculate when regeneration is needed.

4. Salt Dosage Settings: Some advanced Rheem models allow you to adjust the salt dosage used during regeneration. Adjusting the salt dosage can optimize salt usage and minimize waste. Consult your manual for guidance on selecting the appropriate setting based on your water hardness and regeneration frequency.

5. Setting the Regeneration Time: You can typically set the time of day when the softener regenerates. It’s best to choose a time when water usage is low, such as late at night or early morning. This ensures that you have a continuous supply of softened water.

6. Reviewing and Confirming Settings: After entering all the necessary information, carefully review all the settings displayed on the control valve. Make sure everything is accurate before saving the settings.

Starting the Softening Process

After programming the timer/control valve, you can initiate the water softening process.

1. Bypass Valve Position: Ensure that the bypass valve is set to the "Service" position. This allows water to flow through the softener.

2. Initiate Manual Regeneration (Optional): Some Rheem models allow you to initiate a manual regeneration cycle. This is a good way to flush the system and ensure that everything is working properly before normal operation. Consult your user manual for instructions on how to initiate a manual regeneration.

3. Monitor the System: For the first few days, closely monitor the system for any issues. Check for leaks and ensure that the water is indeed being softened.

Refer to the user manual for model-specific instructions on setup and starting the water softener, as the information here is for education purposes only.

Step 4: Post-Installation Checks – Ensuring a Leak-Free and Properly Functioning System

Once you’ve programmed your Rheem water softener and initiated the startup sequence, it’s crucial to conduct thorough post-installation checks. These checks will guarantee that your system is operating correctly, efficiently, and without any leaks. This step is vital for preventing water damage and ensuring you enjoy the benefits of soft water.

Inspecting for Leaks: A Comprehensive Examination

The first and arguably most important step is a meticulous inspection for leaks. This requires a visual examination of every connection you made during the installation process.

Focus Areas:

• Fittings: Pay close attention to the areas where you connected the water lines to the bypass valve and the softener itself. Check the tightness of the fittings, but avoid over-tightening, which can damage the connections or the pipes.

• Bypass Valve: Carefully examine the bypass valve connections. This area is particularly prone to leaks if not properly sealed.

• Drain Line Connection: Ensure the drain line is securely connected and properly sealed.

• Salt Tank: The salt tank should also be inspected. Although leaks in the tank itself are rare, check the connection points if there are any.

What to Look For:

Look for any signs of water droplets, dampness, or water pooling around the connections. Even a slow drip can waste a significant amount of water over time and lead to water damage.

Action Steps:

If you discover a leak, immediately shut off the water supply to the softener using the bypass valve. Then, carefully tighten the connection that is leaking. If tightening doesn’t solve the problem, you may need to disassemble the connection, apply fresh Teflon tape or pipe dope, and reassemble it.

Testing the Water Softener: Confirming Soft Water Production

After verifying there are no leaks, it’s time to test the water to confirm that the softener is actually doing its job.

How to Test:

• Run Water: Open a faucet that is supplied by the softened water system. Let the water run for several minutes to flush out any hard water that may still be in the pipes.

• Use a Water Hardness Testing Kit: Utilize a water hardness testing kit, preferably the same one you used before installation. Follow the instructions provided with the kit to test the water hardness.

Interpreting the Results:

The water hardness reading should be significantly lower than your initial reading, ideally close to zero grains per gallon (GPG). If the water hardness remains high, there may be an issue with the softener’s programming, the salt level in the brine tank, or the system’s regeneration cycle. Refer to the troubleshooting section of your user manual or consider contacting Rheem support for assistance.

Understanding Your Rheem Water Softener Warranty

Familiarize yourself with the specifics of your Rheem water softener’s warranty. Knowing the coverage and the claims process is essential for protecting your investment.

Key Warranty Aspects:

• Warranty Period: Identify the length of the warranty coverage for different components of the softener (e.g., control valve, tank, electronics). The periods typically vary.

• Coverage Details: Understand what the warranty covers (e.g., defects in materials or workmanship) and what it excludes (e.g., damage due to improper installation, freezing, or abuse).

• Registration: Typically, you’ll need to register your water softener with Rheem to activate the warranty. This can usually be done online or by mail.

Claiming the Warranty:

If you encounter an issue covered by the warranty, you’ll need to follow Rheem’s claims process. This usually involves contacting Rheem customer support, providing proof of purchase (sales receipt), and describing the problem. Rheem may require you to provide photos or videos of the issue, and in some cases, they may send a technician to inspect the softener.

Important Documents:

Keep your sales receipt and warranty information in a safe place for future reference. Having these documents readily available will expedite the claims process if you ever need to file a warranty claim.

Step 6: Maintaining Your Rheem Water Softener for Optimal Performance

Just like any appliance, your Rheem water softener requires regular maintenance to ensure it operates efficiently and provides you with consistently soft water for years to come. Neglecting maintenance can lead to decreased performance, costly repairs, or even premature failure of the system. The good news is that maintaining your water softener is a straightforward process. Let’s break it down.

Regular Salt Refills: The Heart of Soft Water

The salt in your water softener’s brine tank is the lifeblood of the softening process. It’s what allows the resin beads to regenerate and continue removing hardness minerals from your water.

Without enough salt, your water softener simply can’t do its job.

Determining Refill Frequency

The frequency with which you need to refill the salt tank depends on a few factors:

• Water Hardness: The harder your water, the more salt your softener will use.
• Water Usage: Larger households that use more water will naturally deplete the salt supply faster.
• Softener Size and Efficiency: More efficient softeners and correctly sized softeners use salt more sparingly.
• Salt Type: Different types of salt dissolve at different rates.

As a general rule, check the salt level in your brine tank at least once a month.

The tank should be no less than one-quarter full, and ideally no more than two-thirds full. Avoid overfilling the tank, as this can lead to salt bridging (more on that below).

Choosing the Right Salt

While several types of salt can be used in water softeners, some are better than others. Here’s a quick rundown:

• Rock Salt: This is the cheapest option but contains the most impurities, which can lead to sludge buildup in the tank. Avoid rock salt if possible.

• Solar Salt: Made by evaporating seawater, solar salt is a cleaner option than rock salt. It’s available in crystal or pellet form.

• Evaporated Salt Pellets: This is the purest form of salt for water softeners. It dissolves evenly and minimizes bridging and buildup. This is the recommended type of salt for most Rheem water softeners.

• Potassium Chloride: A salt-free alternative for those concerned about sodium intake. However, it may be less effective at softening water than traditional salt.

Cleaning the Salt Tank/Brine Tank: Preventing Problems

Over time, sediment, salt residue, and other impurities can accumulate in the brine tank, leading to problems like salt bridging and reduced softener efficiency.

Cleaning the brine tank at least once a year is crucial for maintaining optimal performance.

How to Clean the Brine Tank

Here’s a step-by-step guide to cleaning your water softener’s brine tank:

1. Bypass the Softener: Turn the bypass valve to the bypass position. This isolates the softener from your home’s water supply.

2. Deplete the Salt: Allow the softener to run a regeneration cycle to use up most of the salt in the tank.

3. Disconnect the Brine Line: Carefully disconnect the brine line from the brine tank. This is usually a small tube that runs from the softener head to the tank.

4. Remove Remaining Salt and Water: Use a scoop or wet/dry vacuum to remove any remaining salt and water from the tank. You may need to use a hose to flush out the inside.

5. Scrub the Tank: Use a mild detergent and warm water to scrub the inside of the tank, removing any sediment or buildup.

6. Rinse Thoroughly: Rinse the tank thoroughly with clean water until all traces of detergent are gone.

7. Reassemble: Reconnect the brine line and refill the tank with fresh salt.

8. Return to Service: Slowly return the softener to service by gradually opening the bypass valve.

Addressing Salt Bridging

Salt bridging occurs when a hard crust of salt forms in the brine tank, preventing the salt from dissolving properly and hindering the regeneration process.

If you suspect salt bridging, carefully break up the crust with a long, blunt object like a broom handle (avoid sharp objects that could damage the tank).

Pour warm water over the bridge to help dissolve it. If the bridging is severe, you may need to empty and clean the tank as described above.

By following these simple maintenance steps, you can keep your Rheem water softener running smoothly and enjoy the benefits of soft water for years to come.
