To change a water filter in a filtration system, follow these steps:
-
Run the Faucet: First, open a faucet connected to the filtration system to let the water run. This reduces pressure in the system before you start the filter change as demonstrated in the video.
-
Shut off the Valve: Next, locate the valve that controls the water supply to the filtration system and turn it off as shown in the video. This stops the water flow, preparing you to remove the filter housing.
-
Unscrew the Filter Housing: Proceed to unscrew the filter housing. This is the container holding the filter cartridge.
