In this blog post, we’ll walk you through the steps of how to change your house water filter so you can keep your water clean and fresh. Thanks for reading!

Shut off the water supply to your house

Before you start changing the water filter in your house, you need to shut off the main water supply. This is typically located outside the building and could be a gate valve or a wheel valve. The exact location of this valve will vary depending on your home’s plumbing system.

Locate the Filter Housing

Once you have turned off the water supply, you will need to locate the filter housing unit. This is usually near the main water line coming into the building and should contain a filter cartridge inside it.

Remove the old water filter from your house

The first step in replacing a house water filter is to remove the old one. To do this, locate the filter housing and unscrew it from the pipe that connects it to your plumbing system. Depending on the type of filter you have, you may need to use an adjustable wrench or pliers to loosen it. Once loosened, carefully pull the filter out of the housing.

Inspect and clean the filter housing

Once the old water filter is removed, inspect and clean the filter housing before installing a new one. Use a damp cloth to wipe down both the inside and outside of the housing, then use an old toothbrush or other small brush to remove any debris or accumulated dirt.

Install the new water filter

Now it is time to install the new water filter in your house. Depending on the type of filter you are using, there may be different instructions for installation, so make sure to follow these closely. In most cases, simply attach one end of the filter to the housing and the other end to the plumbing pipe. Once in place, you can use a wrench or pliers to securely fasten it.

Install the new water filter in your house

  1. Shut off the water supply to your home. Depending on the type of filter system you have, turn off either the main shutoff valve or the one that serves just the filter system.
  2. Disconnect the old filter from its housing. This will vary depending on what type of filter housing you have, but usually requires a wrench.
  3. Carefully remove the old filter and discard it. It is important to read the instructions on how to properly dispose of an old water filter, as some contain hazardous materials that must be handled properly.
  4. Install the new filter into its housing, following any specific instructions that come with it. Make sure all connections are properly secured.
  5. Turn the water supply to your home back on, and test the new filter by running a few glasses of water through it. Make sure there is no leakage or other problems before you move on to any other steps.
  6. Replace the cover on the filter housing, making sure it is secure and not leaky.
  7. Finally, check and adjust the pressure of the filter system according to instructions (if applicable). This will ensure that you get the most optimal performance from your new water filter.

Turn on the water supply to your house

Before you begin replacing your house water filter, make sure the main water supply to your house is turned on. This ensures that the flow of water through the new filter is not hindered.

Check for leaks around the new water filter installation

After successfully changing your house water filter, it’s important to check that there are no leaks around the new installation. To do this, first turn on the cold water supply and let the water run for a few minutes. Ensure that all connections have been tightened securely and observe if any water is leaking from the old filter casing or other sealing points. If there is, tighten the connections and recheck.

Doing this helps to ensure that your drinking water will be fresh and uncontaminated when you use it.

Replace the filter housing lid

Carefully remove these, then place the new filter inside and tighten the lid to secure it. Make sure that everything is tightly secured so that there are no leaks or openings through which contaminants can enter your water supply.
