6. Conclusion

Water hoses connected to your kitchen faucet are exposed to constant moisture, detergents, and cleaning chemicals. Over time, this can cause corrosion, rust, or leaks at the base of your sink. A damaged hose not only reduces water flow efficiency but can also pose safety risks such as leaks that damage cabinets or flooring. Timely repair or replacement ensures smooth water supply and keeps your modern kitchen faucet functioning at its best.

• Two replacement water hoses (hot and cold)
• Scissors or utility knife
• Screwdriver
• Adjustable wrench
• Pliers

Estimated time: 15–20 minutes

Step 1: Identify Hot and Cold Water Connections

Most hoses are marked with red for hot water and blue for cold water. If there are no markings, turn off one valve at a time and run the faucet. If only cold water flows, you shut off the hot water valve; if hot water flows, you closed the cold valve.

Step 2: Shut Off the Angle Valve and Disconnect the Faucet

Turn off the angle valves under the sink. Use a wrench to unscrew the hose nut from the valve. Then, remove the faucet's bottom plate and secure clips with the provided faucet tool.

Step 3: Remove the Old Hose from the Faucet

Unscrew the hose from the faucet body. Remember which side connects to hot and cold to avoid reversing them later.
If the hose is stuck:

• Cut the hose with scissors.
• Insert a screwdriver into the cut end.
• Grip it firmly with pliers and twist counterclockwise until loosened.

Step 4: Install the Faucet with New Hoses

Insert the new hot and cold hoses into the faucet, ensuring correct positioning. Reinstall the faucet onto the sink, secure it with the mounting nut, and tighten firmly.

Step 5: Connect Hoses to the Angle Valve

Hand-tighten the hose connections to the valves. Avoid over-tightening to prevent damage.

Step 6: Test and Final Check

Turn on the angle valves and run the faucet. Check for leaks around the hose connections and faucet base. If everything is secure, your water hose replacement is complete.

• Choose high-quality hoses: Stainless steel braided hoses last longer than plastic ones.
• Inspect regularly: Check under the sink for drips, rust, or swelling every few months.
• Replace in pairs: Always replace both hot and cold hoses together for consistent performance.
• Avoid chemical damage: Store harsh cleaning agents away from hose contact areas.

If your faucet is integrated with advanced filtration, boiling water, or chilled water systems, or if the leak is connected to internal components rather than hoses, it's best to call a professional installer or plumber.
