Fix a Leaky Faucet: Repairing Water Intake Leaks · Step 1 of 5
This project details how to fix a leaky faucet caused by a water intake leak. The steps include: 1. **Turning off the water supply:** Turn off both hot and cold water valves under the sink, or the main water supply if necessary. 2. **Preparing the work area:** Place a bucket and towel under the sink to catch any spills. 3. **Disconnecting the water supply lines:** Use an adjustable wrench to carefully disconnect the copper supply lines from the faucet tailpieces. 4. **Inspecting supply lines for damage:** Examine the disconnected supply lines for damage, corrosion, or leaks and replace if necessary. 5. **Reconnecting the water supply lines:** Clean the threads, apply Teflon tape to the faucet tailpieces, reconnect the lines with a wrench, turn the water back on slowly, and check for leaks.

FAQs
How difficult is this water intake leak repair for a DIY beginner, and can it realistically be done in 2 hours?
This project is indeed suitable for beginners, focusing on straightforward disconnection and reconnection of supply lines. The 2-hour estimate is realistic, assuming you have the necessary tools readily available and don't encounter heavily seized or corroded connections. Taking your time to ensure proper sealing is key.
What should I do if the shut-off valves under my sink don't work or are stuck, preventing me from turning off the water?
If the local shut-off valves are faulty or seized, you'll need to turn off the main water supply to your entire home. Locate your home's main water shut-off valve, usually in the basement, garage, or utility closet, and turn it clockwise until the water flow stops completely. Remember to notify anyone in your household before doing this.
Is Teflon tape absolutely necessary when reconnecting the water supply lines to the faucet tailpieces, and how should it be applied?
Yes, Teflon tape (also known as PTFE tape or plumber's tape) is highly recommended for these threaded connections. It acts as a lubricant to help threads seal better and prevents leaks. Wrap the tape clockwise around the threads of the faucet tailpiece 2-3 times, ensuring it's snug and doesn't cover the opening.
I reconnected the supply lines, but the faucet is still leaking where they attach. What's the most common reason for this, and how can I fix it?
The most common reasons for a persistent leak are improperly applied Teflon tape or loose connections. First, ensure the Teflon tape was wrapped clockwise and isn't bunched up. Then, gently tighten the supply line nuts a bit more with your adjustable wrench, being careful not to overtighten and strip the threads.
