How to Install a Kitchen Faucet: 6 Step Guide
Installing a new kitchen faucet is a DIY-friendly project that can be completed in under 1 hour with basic tools. Follow these steps for a leak-free installation.
🛠️ Tools & Materials Needed
✅ New kitchen faucet (check sink compatibility)
✅ Adjustable wrench or basin wrench
✅ Plumber’s putty or silicone sealant
✅ Teflon tape (for threaded connections)
✅ Bucket & towels (to catch water)
✅ Flashlight (for visibility under sink)
🔧 Step-by-Step Installation
1. Turn Off Water Supply
- Locate shutoff valves under the sink (turn clockwise).
- Open faucet to drain remaining water.
2. Remove Old Faucet
- Disconnect supply lines with wrench (place bucket underneath).
- Loosen mounting nuts under sink (use basin wrench if tight).
- Lift old faucet out from above.
3. Clean Sink Surface
- Scrape off old plumber’s putty or debris.
- Wipe with rubbing alcohol for better adhesion.
4. Install New Faucet
A. Single-Hole Faucet:
- Insert faucet tailpiece through sink hole.
- Secure with mounting nut underneath (hand-tighten, then wrench).
B. 3-Hole Faucet (with Deck Plate):
- Place deck plate over holes.
- Insert faucet through center hole.
- Tighten mounting bracket under sink.
5. Connect Water Lines
- Wrap Teflon tape on supply line threads.
- Attach hot/cold lines to faucet tails (hand-tighten + ¼ turn with wrench).
6. Seal & Test
- Apply plumber’s putty under faucet base (if required).
- Turn water back on slowly.
- Check for leaks at connections.

💡 Pro Tips for Success
✔ Use a basin wrench for tight spaces under sink.
✔ Overtightening cracks seals – snug is enough.
✔ Upgrade to braided stainless supply lines (last longer than rubber).
⚠️ When to Call a Plumber
- If pipes are corroded/seized.
- If no shutoff valves exist (may need main water turnoff).
🛑 Common Mistakes to Avoid
❌ Skipping Teflon tape (causes leaks).
❌ Forgetting to remove old putty (prevents proper sealing).
❌ Cross-threading connections (damages threads).
⏱️ Time & Cost
⏳ 30-60 minutes (first-timers may take 90 mins).

FAQ’s
Can I install a kitchen faucet myself?
Yes, you can install a kitchen faucet yourself if you have basic tools and DIY skills. First, shut off the water, disconnect the old faucet, and clean the mounting area. Then, install the new faucet following the instructions, secure it tightly, and reconnect the supply lines (use plumber’s tape to prevent leaks).
Finally, turn the water back on and check for leaks. If your plumbing is old or complicated, or if you’re uncomfortable, call a plumber—but most standard faucets are DIY-friendly!
Do you need plumbers putty to install a kitchen faucet?
Not always. Many modern faucets use a rubber gasket instead of plumber’s putty for a watertight seal. Check your faucet’s instructions if needed.
