How to Change a Filter in a Water Filtration System?

When you are installing a new water filtration system, it is important that you replace the filter before you turn on the main water supply. This will prevent sediment from entering your home and keep your water piping clean. It is also a good idea to flush your lines to remove any rust that may be present.

If your filter is a canister style, you can use a simple wrench to untwist the canister from the housing. Some people use a plastic pipe to hold the wrench over the end to give it better leverage. However, this can make the wrench brittle and break if you exert too much force. Instead, a strap wrench is a more effective tool. 

If your filter is a whole house unit, you will need to cut off the water line to your house. Be careful not to pull the pipe from the wall. You should also check to ensure that the outlet valve is closed. Otherwise, you will risk the water draining back into your home. 

First, you will need to clean the inside of the filter housing. Use a rag or paper towel to wipe down the casing. Then, soak the filter in warm soapy water to remove any debris. 

Once you have cleaned the canister and removed the old cartridge, you will need to replace it. It is a good idea to measure the new filter for length. There are many different types of filters available. Using the owner’s manual, you can determine the correct size. Alternatively, you can measure the existing filter to find out its exact size. 

Once you have determined the right size, you can begin to install the new cartridge. To start, you will need to remove the old o-ring. In some cases, you will need to lubricate the o-ring with silicone grease before putting it back on. 

Next, you will need to insert the new o-ring into the groove in the casing. Check the o-ring for any nicks or other damage. If necessary, you can clean it with vinegar. 

After you have inserted the new o-ring, you can begin to remove the old filter. This should be easy, as most filters are easy to remove. Depending on your model, you may need a special wrench or other tool to do the job. A filter wrench works best, but you can also use a strap wrench. 

After you have finished, you should rinse the filter and the housing to remove any remaining sediment. For a whole house unit, you will need an empty bucket. Place the bucket under the unit to catch any spilled water. An empty bucket is also a good way to prevent any unwanted leaks. 

To complete the job, you will need to test the pressure. Make sure to wrap a towel halfway across the unit before you release any pressure. Overpressure can cause the filter to open and the water to pour out. 

Before you begin, it is a good idea to note the date of the filter replacement. This will give you a reference for when you need to replace the filter in the future.
