A water filter bypass plug is a device that allows you to bypass the water filter on your refrigerator so that unfiltered water can be used for specific purposes. Bypass plugs are often used in refrigerators with built-in ice makers or water dispensers, as they allow these components to work without requiring filtered water.

How To Install Water Filter Bypass Plug?

Find water filter housing: Depending on the model of the water filter, they can be found in different locations. Commonly they are located underneath a sink or near the main water line.

Locate the lines: The initial step in installing a water filter bypass plug is to locate the lines connecting the filter with its bypass. Generally, these lines are either located at the point of entry for your home’s water supply or near where your current filter is installed.

Shut off water supply: Before beginning the installation process, it’s essential to shut off your home’s main water supply. This can usually be found outside the house, near a wall or meter. To turn it off entirely, rotate the valve clockwise until you hear a click.

Disconnect water: Find the main water line and disconnect it by turning off the shut-off valve. Then, use adjustable pliers to loosen the nut on the filter housing and unscrew it.

Remove the filter cartridge: Locate it and unscrew it from the housing. Please keep track of any parts you have removed and set them aside until needed later.

Install the plug: Install the plug into the inlet side of your water filter housing. Ensure the O-ring is between the plug and the housing to ensure a proper seal.

Make sure that plug is installed correctly: Make sure that the plug is properly sized for your water filter system. A wrong size could cause leaks and other problems.

Check for leaks: After installation, check for leaks. If water leaks from the filter, tighten the fittings by hand or with a wrench. Make sure that all joints are secure and not damaged in any way. To test for leaks, turn on the water supply and look for any signs of leakage around the filter bypass plug.

Replace the cover of the filter housing: Once the filter bypass plug has been installed, replace the cover of the filter housing. This can be done by carefully placing it over the filter and aligning its screw holes with those on the filter housing. Securely fasten this cover using screws that come with the unit and tighten them until they are tightly secured.

  • The bypass plug or valve allows filtered water to flow directly from the pre-filter to the storage tank, bypassing the membrane.
  • This is useful when it is necessary to flush out large amounts of sediment that can clog and damage the membrane or when you need access to more water than what’s available by using only the membrane.
  • The bypass valve allows you to operate the system, making it ideal for high-demand situations. It also helps reduce membrane fouling and maintenance time, saving energy and money in the long run.
  • Additionally, a bypass plug or valve can help preserve the life of your reverse osmosis system by protecting it from contaminants that would otherwise pass through the membrane.

Water flow is too slow: If the water flow from the filter is too slow, ensure that the bypass plug and filter are in good condition and installed correctly. Additionally, check for any blockages in any of the hoses or other components in the system.
