Whirlpool WRT518SZFM00 Water Filter Replacement
Why The GXRTDR water filter…
The GXRTDR water filter is the correct replacement for the Whirlpool WRT518SZFM00 top-freezer refrigerator. This model is icemaker-ready, meaning the water filter is an inline filter installed in the water supply line leading to the icemaker, not inside the fresh food compartment. The GXRTDR is specifically designed for this external inline application, connecting with 1/4-inch compression fittings.
Common Mistakes When Ordering
- Ordering a refrigerator water filter designed for internal fresh food compartment installation.
- Confusing the WRT518SZFM00 with models that use a push-in style inline filter instead of compression fittings.
- Attempting to install a filter not rated for external inline use, which can lead to leaks.
Installation & Replacement Guide
Location & Installation: The GXRTDR water filter for the Whirlpool WRT518SZFM00 is installed externally in the water supply line behind the refrigerator, typically near the water shut-off valve.
Replacement Frequency: Replace the GXRTDR water filter in your Whirlpool WRT518SZFM00 every 6 months or 200 gallons, whichever comes first.
