The ultimate guide to banishing cold water from your kitchen tap: how to fix the hot water issue

A malfunctioning hot water tap in the kitchen can be a major inconvenience, hindering your daily tasks and disrupting your comfort. If you’re facing this issue, fret not! This comprehensive guide will empower you with the knowledge and step-by-step instructions to fix your hot water tap like a pro.

Identifying the Problem

Before embarking on the repair, it’s crucial to determine the root cause of the problem. Common issues include:

• Faulty cartridge: The cartridge controls the flow of water and can become worn out or damaged over time.
• Damaged O-rings: These rubber seals prevent leaks and can deteriorate due to age or excessive use.
• Mineral buildup: Hard water can cause mineral deposits to accumulate, obstructing the flow of hot water.

Tools and Materials Required

To fix your hot water tap, you’ll need the following tools and materials:

• Adjustable wrench
• Phillips and flathead screwdrivers
• New cartridge (if needed)
• O-ring kit
• Plumber’s tape
• Rags

Step-by-Step Repair Instructions

1. Isolate the Water Supply

Turn off the water supply to your kitchen sink by closing the isolation valves located under the sink.

2. Remove the Handle

Using a Phillips or flathead screwdriver, remove the screws that secure the handle to the tap. Gently pull the handle straight up to detach it.

3. Remove the Cartridge

Loosen the retaining nut that holds the cartridge in place using an adjustable wrench. Grip the cartridge firmly and pull it straight out.

4. Inspect and Replace the Cartridge

Examine the cartridge for any visible damage or wear. If it’s damaged, replace it with a new cartridge by inserting it into the tap and tightening the retaining nut.

5. Replace the O-rings

Remove the old O-rings from the cartridge and the tap body. Apply a thin layer of plumber’s tape to the threads of the tap body and install the new O-rings.

6. Reassemble the Tap

Insert the cartridge back into the tap and tighten the retaining nut. Replace the handle and secure it with the screws.

7. Restore Water Supply and Test

Turn on the water supply and check for any leaks. If there are no leaks, your hot water tap is now repaired!

Additional Tips

• If you’re unsure about the cause of the problem, consult a qualified plumber for professional assistance.
• Use a flashlight to inspect the tap for any hidden damage or mineral buildup.
• If the mineral buildup is significant, you may need to use a descaling solution to dissolve it.
• Apply a small amount of grease to the O-rings to prevent them from sticking in the future.

Troubleshooting

If you encounter any problems during the repair, here are some troubleshooting tips:

• No hot water: Check if the water heater is turned on and set to the correct temperature.
• Leak from the base of the tap: Tighten the retaining nut or replace the O-rings.
• Handle is loose: Tighten the screws that secure the handle.
• Cartridge is stuck: Use a wrench to loosen the retaining nut and apply penetrating oil to the cartridge.
