How to Fix a Leaky Faucet
We've all been there - that annoying drip… drip… drip sound echoing through a quiet kitchen or bathroom. While it might seem minor, even a slow leak can waste more than three gallons of water a day, which adds up on your water bill and harms the environment. The good news? You don't need to be a plumber to fix it.
Whether it's your kitchen tap, bathroom faucet, or 5 in 1 water tap, repairing a small leak is easier than you think. Let's walk through the process step-by-step.
- Saves water and money: A constant drip can waste hundreds of liters every month.
- Prevents long-term damage: Leaks can lead to rust, corrosion, and mold under the sink.
- Extends faucet lifespan: Regular maintenance keeps your 5 in 1 water tap working efficiently.
| Tool | Purpose |
|---|---|
| 1/8-inch Allen wrench | To remove seats and springs |
| Needle-nose pliers | To tighten or remove rings |
| Tongue-and-groove pliers | For dome-shaped caps |
| Screwdriver | To remove handles |
| Replacement parts | Seats, springs, cam, and packing as needed |
Step 1: Turn Off Water Supply
Shut off both hot and cold valves under the sink. Turn on the faucet to drain any remaining water.
Step 2: Remove the Handle
Pop off the screw cover and unscrew the handle with a screwdriver or Allen wrench. Lift the handle off carefully.
Step 3: Inspect the Adjusting Ring (If Present)
Older faucets may have an adjusting ring. Tighten it gently if the leak is coming from that area. If tightening doesn't help, continue with the next steps.
Step 4: Remove the Cap and Ring
Place a soft cloth over the dome cap to avoid scratches. Use tongue-and-groove pliers to twist it off slowly.
Step 5: Take Out the Stem Assembly
Pull out the round metal stem - this includes the ball, cam, and packing. Replace worn-out parts to stop internal leaks.
Step 6: Replace Seats and Springs
Inside the valve, you'll find small rubber seats with springs beneath. Use an Allen wrench to remove both. Replace them with new ones.
Step 7: Flush the Water Lines
Before reassembling, remove the aerator and turn on both valves to flush the lines for one minute. This clears any debris.
Step 8: Reassemble the Faucet
Insert new seats and springs, replace the ball assembly, and align it correctly. Then reinstall the cam, packing, and handle.
Step 9: Turn On Water & Test
Turn the water back on and check for leaks. If the faucet runs smoothly without dripping - congratulations, you've done it!
