Step-By-Step Installation Guide

Mounting The Water Filter Onto The Sink

Mounting the water filter onto the sink is a simple process that can be completed in a few easy steps:

  • First, locate the spot where you want to install the filter. This spot should be easily accessible and close to the existing plumbing.
  • Next, attach the mounting bracket to the spot where you want to install the filter using screws. Make sure the bracket is level and secure.
  • Now, attach the filter to the bracket. Ensure that the filter is level and secure, and that it’s facing the right way based on your specific model’s instructions.

If you’re unsure about how to install the mounting bracket, refer to your specific model’s manual for detailed instructions.

Connecting The Filter To The Existing Plumbing

Connecting the filter to the existing plumbing is a straightforward process that involves a few simple steps:

  • First, turn off the water supply to the sink where you’ll be installing the filter. You can usually do this by turning off the valve under the sink.
  • Next, connect the incoming water line from your existing plumbing to the water filter’s input valve. Ensure that the connection is tight and secure.
  • Now, connect the outgoing water line from the filter’s output valve to the faucet’s cold water side. Ensure that the connection is tight and secure.
  • Once the connections are in place, turn on the water supply and check for any leaks.

Checking For Leaks And Proper Water Flow

After you’ve installed the filter and connected it to the existing plumbing, it’s essential to check for any leaks and ensure that the water flow is adequate:

  • Check all connections for leaks, including where the filter attaches to the mounting bracket and where it connects to the incoming and outgoing water lines.
  • Turn on the faucet and check to see if the water is flowing correctly. If the flow seems weak or uneven, check your installation steps and connections and correct any issues accordingly.
  • If you do notice a leak, turn off the water supply and check the connections once again. Tighten any loose fittings and connections and try again.

Activating And Maintaining The Filter

Finally, once your filter is installed, you’ll need to activate and maintain it to ensure that it works correctly and stays in good condition:

  • Before using the filter for the first time, you may need to activate it based on the specific model’s instructions.
  • To maintain the filter, follow the manufacturer’s guidelines regarding filter replacement and maintenance. This will likely include regular filter replacement and cleaning to ensure that the filter works efficiently.
  • Pay attention to the filter’s performance and make note of any changes in water quality or flow. If you notice any issues, refer to the manufacturer’s guidelines and adjust your maintenance routine accordingly.
