StumbleUponInstall a refrigerator water filter to remove the bad taste from drinking water and ice cubes. An inline refrigerator water filter ($25 with connection fittings) reduces chlorine, rust, sediment and odors for water- and ice-dispensing refrigerators. Filters are available from home centers and appliance stores. We used GE Appliances model GXITQ, (800-626-2000; www.geappliances.com).
The filter splices into the standard 1/4-in. copper or plastic refrigerator water supply line (Photo 1). Locate the filter as close as possible to the water shutoff valve. Leave at least 6 in. of clearance between the wall and refrigerator when installing the filter behind a refrigerator. Once you install the system, quick-connect fittings make it easy to change the filter.
Turn off the shutoff valve and disconnect the 1/4- in. supply line from the valve (hold a bucket under the valve to catch residual water). Some types of valves leak. You may have to turn off the main water supply valve to your home. Cut back the tubing (Photo 1) and attach the quick-connect fittings (Photo 2). Snap the filter into the fittings.
Secure the tubing on the fridge side with a 1/4-in. copper strap and flush the filter to dispense any fine loose carbon particles (Photo 3). If a leak occurs, tighten the nuts or fittings. Strap the filter to any nearby support to take stress off the tubing. Write the installation date on the filter and replace it every six months with a new one ($20).

1. Turn off the shutoff valve, and disconnect the supply line. Mark the filter width on the supply line and cut it out. Tighten the pipe cutter in small increments to avoid pinching the soft copper tube. Deburr the cut end with sandpaper or a file (cut plastic tubing with a utility knife).

2. Slip the brass nut and ferrule onto the tubing. (If you have a plastic water line, insert the brass reinforcers into the tube ends). Thread the brass nut onto the fitting until finger tight, and twist it one full turn with two wrenches (the longer fitting goes on the supply side).

3. Snap the filter into the supply side. Make sure the waterflow indicator points toward the fridge. Support the filter and slowly open the water shutoff valve until water sprays out of the unhooked end. Hang a bucket from a screw and flush water through the filter for approximately five minutes (two to three gallons), and then snap it into the other fitting.
