If you have an icemaker that doesn't have a filter, it is easy to add one. An in-line water filter is a quick plumbing job that can be added between the wall valve and the refrigerator. Once the filter is installed, replacing the cartridge takes only minutes.

Start by pulling the refrigerator away from the wall and getting access to the water valve at the wall. Turn the water off to this valve. In line filters are sold either in kits, or you will need to assemble the components to make up the system. I prefer to use braided steel reinforced water lines as these typically carry a 10 year warranty against leaks.

These will screw onto the wall valve. The filter cartridge will connect to the other side of this line. At this point it is a good idea to place the filter into a bucket and turn the water back on temporarily to flush any sediment and charcoal from the filter. A 2nd line will connect the filter cartridge to the refrigerator's icemaker.

The kits will have either screw-on fittings or quick-connect fittings. The quick-connect fittings push into the mating fitting and have a slide that holds everything together.

Once everything is connected, turn the water valve back on and check for leaks. Then just push the refrigerator back into place.
