IMPORTANT! Do not install without a rubber washer or coupling nut. Rigid supply lines with a flange riser require both the rubber washer and coupling nut to provide a watertight seal to the fill valve shank.
NOTE: The rubber washer and coupling nut (42397) is included with your toilet tank.
- Slide the coupling nut onto the rigid supply line.
- Connect the rigid supply line to the supply stop.
- Slide the coupling nut to the top of the rigid supply line.
- Press the rubber washer into the coupling nut.
- Handtighten the coupling nut to the fill valve shank.
