How to Replace Faucet Washer? DIY Guide Step by Step

A dripping faucet is more than just annoying "drip, drip, drip". One dripping faucet wastes 200-300 liters of water monthly = approximately 15 EUR annually. And repair is so simple you can handle it in 15 minutes with tools you already have at home. However, if faucet drips even after washer replacement or problem is in older fixture, plumbing work in Bratislava is more suitable.

Why Does Faucet Drip?

The reason is simple: worn rubber washer.

How it works:

1. When you close faucet, metal valve presses on rubber washer
2. Washer seals water supply = water doesn't flow
3. After years of use, rubber wears out, hardens, cracks
4. Washer no longer seats perfectly = water seeps through = dripping

Washer lifespan: 3-7 years (depends on water quality and frequency of use)

What You Need for Washer Replacement

Tools (you probably already have at home)

• 🔧 Adjustable wrench or crescent wrench
• 🪛 Screwdriver (flat or Phillips)
• 🧽 Cloth - Dry work surface
• 🪣 Bowl or cloth - Under faucet (catches water remnants)
• 💡 Flashlight (optional) - Better view under sink

Material (buy at hardware store)

• 🔴 New washer (2-3 EUR for pack of 5)
• 📏 Correct size: 1/2" (most common) or 3/4"
• 💡 TIP: Take old washer with you to hardware store - compare size

Step by Step: How to Replace Washer

STEP 1: Shut Off Water Supply (1 minute)

MOST IMPORTANT STEP! Without this there will be flood.

Where to find shut-offs:

• Under sink - Two small valves (cold + hot water)
• In bathroom - In cabinet under sink
• In kitchen - Under sink
• Main shut-off - If you can't find local valve, close main (next to water meter)

How to close valve:

1. Turn valve clockwise (to right)
2. Turn until you feel resistance (fully closed)
3. Test: Open faucet - does water flow? If yes, close more

STEP 2: Drain Remaining Water (30 seconds)

1. Open faucet fully (cold and hot side)
2. Let remaining water drain from pipes
3. Water stopped flowing? You can continue

STEP 3: Disassemble Faucet (5 minutes)

Now actual work begins:

A) Remove decorative cap

1. On top of faucet is colored cap (blue/red)
2. Carefully pry it out with screwdriver or fingernail
3. Underneath is screw

B) Unscrew faucet handle

1. Insert screwdriver into screw
2. Turn counterclockwise (to left)
3. Lift handle - should come off easily

C) Unscrew valve top

1. Under handle you'll see hexagonal or round key valve
2. Use adjustable wrench

STEP 4: Remove Old Washer (1 minute)

On bottom part of valve stem is rubber washer.

1. Look at bottom of valve stem
2. You'll see small rubber pad (washer)
3. Pry it out with screwdriver or finger
4. If firmly attached, use small knife

Checking old washer condition:

• ✅ Hard as plastic? Definitely replace
• ✅ Cracked? Definitely replace
• ✅ Deformed? Definitely replace
• ✅ Water marks? Definitely replace

STEP 5: Clean Valve Seat (2 minutes)

Important! People often skip this → washer new, but still drips.

1. Look into opening in faucet (where valve was)
2. You'll see metal ring (valve seat)
3. Wipe it with cloth - remove limescale, dirt
4. Check with finger - must be smooth! Not rough
5. If you feel irregularities → use gentle sponge

STEP 6: Install New Washer (1 minute)

1. Take new washer
2. Check it's correct size (compare with old)
3. Put washer on bottom part of valve stem
4. Press with finger - must sit firmly
5. Check it sits evenly (not crooked)

STEP 7: Reassemble Faucet (3 minutes)

Reverse procedure from disassembly:

1. A) Insert valve back into faucet
2. Valve with new washer insert into opening
3. Screw in by hand clockwise
4. Tighten with wrench - CAUTION: Not too tight! (could damage washer)
6. B) Attach faucet handle
7. Slide handle onto valve shaft
8. Screw in screw clockwise
9. Tighten firmly
11. C) Attach decorative cap
12. Press colored cap into place
13. Hear click? Sits well

STEP 8: Open Water Supply and Test (2 minutes)

1. Open valves under sink (or main shut-off)
2. Slowly turn counterclockwise
3. Listen! Hear hissing? = leak
4. Check visually - dripping anywhere?
5. If everything OK, open faucet
6. Let run 10 seconds
7. Close faucet completely
8. Wait 5 minutes - Dripping? If not = success! ✅

Troubleshooting - What If It Doesn't Work?

Problem 1: Faucet Still Drips After Washer Replacement

Possible causes:

• ❌ Wrong washer size - Try different size
• ❌ Washer backwards - Some have correct orientation, flip it
• ❌ Damaged valve seat - Grooves, pits → Need grinding or faucet replacement
• ❌ Valve not tight enough - Tighten bit more
• ❌ Valve too tight - You crushed washer → Loosen bit
• ❌ Dirt in seat - Disassemble again, clean more thoroughly

Problem 2: Water Leaks Around Valve Stem (not from spout)

This isn't problem of washer on bottom, but worn packing around shaft.

Solution:

1. Tighten packing nut (right under handle)
2. If that doesn't help → Packing replacement (more complicated, maybe call technician)

Problem 3: Faucet Hard to Turn After Replacement

You probably tightened too much.

Solution:

1. Close water again
2. Disassemble handle
3. Loosen valve by 1/4 turn
4. Reassemble, test

When to Rather Call Professional?

Washer replacement is DIY-friendly, but sometimes it's better to call technician:

• 🔧 Old faucet (20+ years) - Screws may be rusted, risk of cracking
• 💧 Leak around valve stem - More complicated repair
• 🔩 Can't unscrew valve - Risk of faucet damage
• 🏚️ Damaged valve seat - Need grinding or faucet replacement
• ❓ Not sure - Rather pay 60 EUR than risk flood

• ✅ Don't close faucet with great force - Gentle touch sufficient, unnecessary force wears washer
• ✅ Use faucet regularly - Unused faucets dry out sooner
• ✅ Descale faucet once yearly - Limescale damages valve seat

• ✅ Water filter - If you have hard water, consider filter → Less limescale
