It does not matter whether you install the water inlet or outlet first.
-
Remove the water hose nut from the spindle and pass the water hose through.
-
Insert the tip of the water hose into the spindle's water inlet.
-
Tip: If the water hose is difficult to insert, you may use a lighter or heat blower to soften the tip. However, exercise caution to avoid damaging the hose. After warming it, carefully insert it into the spindle's water inlet.
-
Proceed with caution and do this at your own risk, as the plastic may become hot and cause burns. Use a towel or cloth to handle the warmed hose safely.
-
Slide the water hose nut down and securely tighten it onto the spindle inlet thread.
