Turn Off Water Supply

Before proceeding with removing the water filter under your sink, the first step is to turn off the water supply. This is important for water filter maintenance and plumbing safety. Follow these steps to safely turn off the water supply:

  1. Locate the water shut-off valve: Typically, the shut-off valve is located under the sink or in the basement near the water main. It may be a lever or a knob that you need to turn.

To properly dispose of the filter, wrap it in a plastic bag to contain any residual water and prevent leaks. Check with your local waste management facility for guidance on the correct disposal method for your specific type of filter. Some filters can be recycled, so it's important to follow the appropriate recycling guidelines if applicable.

Cleaning the area where the filter was housed is important to prevent any buildup of dirt or bacteria. Wipe down the housing with a mild detergent or a mixture of water and vinegar to disinfect the surface thoroughly. Let it air dry before reinstalling a new filter.
