How To Change a Whole House Water Filter

Whole house water filters play a pivotal role in ensuring that every tap in our homes delivers water free from contaminants. Unfortunately, their efficiency diminishes over time, necessitating regular maintenance and filter changes.

How can homeowners tackle this task with ease? Changing a whole house water filter involves:

  • Shutting off the water
  • Releasing pressure
  • Removing the old filter
  • Cleaning the canister
  • Inserting a new filter
  • Ensuring there are no leaks

Learn more about how to insert a replacement filter for a whole house water filter cartridge below.

The Types of Whole House Water Filters

Whole house water filters come in various designs, but the most common are cartridge-based and tank-based systems. Cartridge-based systems use cylindrical cartridges that trap contaminants as water passes through. They are easy to install, simple to maintain, and are ideal for homes with moderate water usage. Over time, these cartridges need replacement to maintain optimal water quality.

On the other hand, tank-based systems use a tank filled with a filtering medium, like activated carbon or other media, to purify water. These systems are suited for homes with high water usage or those needing advanced filtration. The filter media in tank-based systems eventually gets exhausted and requires periodic replacement to ensure the water remains clean. Learn more about each type before deciding which is right for your home.

How to Change the Filters in a Whole House Cartridge Filtration System

Changing filters in a cartridge filtration system is a straightforward process that homeowners can manage with a few tools and precautions. The few steps to follow include:

1. Turn Off the Water

Start by turning off the main water supply to the filtration system. This will prevent any unexpected water flow and ensure a safe working environment. Always check if the water flow has ceased before proceeding.

2. Activate the Pressure Release

Most filtration systems have a pressure release button. Pressing this releases any built-up pressure inside the canister, making it easier and safer to open.

3. Untwist the Filter and Remove the Cartridge

Using a filter wrench, carefully untwist the filter canister from the housing. Once opened, remove the old cartridge and set it aside for disposal or recycling.

4. Clean the Canister

With the old cartridge removed, clean the inside of the canister using mild soap and water. Rinse thoroughly to ensure no soap residue remains. This step ensures the new filter sits in a clean environment.

5. Replace the Filter

Insert the new cartridge into the canister, ensuring it sits properly. Follow the manufacturer’s guidelines for correct placement, as some filters might have a specific orientation. If the orientation is not right, the filter could leak.

6. Visually Inspect the System

Before reassembling the system, visually inspect all components for wear and tear. Ensure seals and gaskets are in good condition to prevent potential leaks. You should also take a close look at the O-ring to ensure it isn’t torn or worn out.

7. Inspect the System for Leaks

Once the filter is replaced and the canister is reattached, slowly turn on the water and check for any leaks. Address any leaks immediately to prevent water damage.

8. Replace the Other Filters If Necessary

If your system uses multiple cartridge filters, repeat the process for each one, ensuring each filter is appropriately replaced. Remember to check the O-ring each time and ensure the orientation is correct.

9. Turn on the Water

After ensuring all components are secure and there are no leaks, fully turn on the water supply. Monitor the system for a few minutes to ensure everything functions correctly.

Changing the Filter Media in a Tank-Based Water Filter

Changing the filter media in tank-based systems requires a bit more attention than cartridge systems but is still straightforward with proper guidance. Please reach out to use with any questions about your DROP units. The few steps to follow include:

1. Turn Off the Water

Always begin by shutting off the water supply to the filter system. This ensures a safe working space without unexpected water flow. It’s a crucial first step to prevent unwanted water spillage and any potential mishaps.

2. Turn On the Bypass Setting

Most tank-based systems come equipped with a bypass setting. Engage this setting to divert water away from the filter tank during the media changing process. This allows you to work on the filter without disrupting the main water supply.

3. Disconnect the Tank

Carefully disconnect the tank from the system. Depending on your setup, this might require some basic tools. Ensure you’re familiar with the system’s connections to prevent any damage.

4. Turn the Water Back On

With the tank disconnected, you can turn the water back on to supply the rest of your home. This ensures that other household activities, such as washing or cooking, are not disrupted.

5. Remove the Old Media

Open the tank and take your time to remove the exhausted filter media. Dispose of the old media following the manufacturer’s guidelines or local disposal regulations. Proper disposal is essential for environmental safety and compliance.

6. Wash Out the Media Inside

Before introducing new media, clean the inside of the tank thoroughly. This helps to remove any residues or leftover media particles. A clean tank ensures that the new media performs at its optimal level, guaranteeing better water quality.

7. Add the New Media

Now, carefully pour the new filter media into the tank. Following the manufacturer’s instructions regarding the quantity and method is crucial to ensure the filter functions correctly. Incorrect amounts can lead to inefficiencies or system malfunctions.

8. Put the Tank Head Back On and Soak the Media

After adding the new media, carefully reattach the tank head. Ensure a tight fit to prevent leaks. Then, allow the media to soak for the recommended time, typically a few hours, to activate its filtering properties.

9. Rinse the Media

Post-soaking, run water through the system to rinse the media. This step is crucial as it removes any fine particles or dust from the media. It ensures that once the system is fully operational, there are no undesired particles in your water.

10. Return the Tank to the Filter and Flush It

Once rinsed, reconnect the tank to the filtration system securely. Ensure all connections are tight and in place. Finally, turn off the bypass setting, and let water flow through the system, flushing the tank, and prepping it for regular use.

How To Take Care of a Whole House Water Filter

Proper maintenance of your whole house water filter ensures longevity, optimal performance, and consistently pure water for your household. Regular care can prevent unexpected issues and ensure that you always have access to clean, safe water. A few steps you need to take to protect your water filter include:

  • Regular Inspections: At least once every three months, visually inspect your system for any signs of wear, damage, or potential leaks. Regular checks can help detect issues early, ensure timely repairs, and prevent bigger problems down the line.
  • Keep a Replacement Schedule: Understand the lifespan of your filter or filter media and mark your calendar for regular replacements. Consistent filter changes ensure that water quality is not compromised and the system operates at peak efficiency.
  • Avoid Using Harsh Chemicals: Avoid using aggressive chemicals when cleaning the system, especially the canister. Mild soap and water are usually sufficient, ensuring that no harmful residues affect water quality or damage the system components.
  • Monitor Water Pressure: A drop in water pressure might indicate a clogged filter or other issues within the system. Regularly monitoring the pressure can help you determine when maintenance or filter changes are due, ensuring uninterrupted water flow.
  • Stay Informed with Manufacturer Guidelines: Always refer to the manufacturer’s guidelines for maintenance, cleaning, and replacement procedures. Staying informed ensures that you’re following the best practices tailored for your specific system.

While whole house water filters are designed to operate efficiently with minimal intervention, proactive care can extend their life and enhance performance. Adopt these care habits, and you’ll have a system that serves you well for years to come.
