Installing an iron filter in your home can help you improve the overall well water quality, reduce staining and discoloration, and solve other water-related problems. Iron is one of the most common contaminants in residential water supplies, and it can be difficult to remove without a specially designed filtration system.

Knowing where to install an iron filter to remove iron bacteria is essential for the best results.

Key Takeaway
  • Install your iron filter close to where your main water supply enters your home.
  • Also, consider installing the iron filter in a dry, level, and non-freezing area.
  • Once the installation is done, test the system for any leaks.

Iron Filter Installation

Follow these steps to install an iron water filter:

Location of the Iron Filter

When installing an iron filter for well water, it is important to determine its location carefully. The ideal location for the filter will depend on various factors, such as the type of filter you are using, your water source, and your home’s plumbing system. Here are some key points to consider when deciding where to install your iron filter.

Install the system on the main water supply

You should ensure that the iron filter is located close to where your main water supply enters your home. This will allow the filter to remove contaminants before they effectively enter your plumbing system.

Install on a dry, level, and non-freezing area.

You should also consider installing the iron filter in a dry, level, and non-freezing area free from flooding or high humidity. This will help to prevent any damage or corrosion to the unit over time.

Install the system after the pressure tank.

The iron filter should be installed after the pressure tank. This will make it easier for the unit to effectively remove contaminants from the water supply before entering your plumbing system.

It is also important to note that some iron filters may require specific installation locations based on their design or technology.


  • Firstly, ensure that all necessary tools and materials are readily available. Depending on your piping configuration, you will need a pipe cutter, soldering torch and flux, Teflon tape or pipe dope, compression fittings, or sweat fittings.
  • Measure the length of pipe required and use a pipe cutter to cut it accordingly. The edges must be smooth to prevent leaks or clogs in the future.
  • Once the pipe is cut, apply a small amount of flux by rubbing it around the pipe’s end and over the fitting’s end. This will create a clean surface for soldering.
  • Heat the fitting using a propane torch and apply a small amount of solder to the pipe and fitting. This will create a joint that is stronger than the original pipe. The piping must be kept at a temperature between 700°F and 1,000°F to ensure that the solder flows properly.
  • The solder should flow freely into the joint, creating a smooth, rounded surface. Once the pipe cools to about 500 F, wipe the excess solder with a piece of cloth to clean it up.
  • Finally, sand the joint down to ensure that it is smooth.

  • Firstly, you’ll need to determine how hard your water is by performing a test. You can then set up the system based on these results using the manufacturer’s instructions as a guide.
  • Next, you’ll need to program the regeneration cycle of the filter according to your household’s needs. Consider factors such as family size and water usage when deciding on the frequency of regeneration cycles.

Run the system

After setting the programming, the final step is running the system.

  • The first thing you should do when running your new iron filter system is to check for leaks.
  • Next, slowly turn on your water supply valve to allow for proper pressure build-up in your system.
  • Once you have turned on your water supply valve, let your filter run for at least 15 minutes before using any appliances or faucets in your home.
