Why Does My Bathroom Faucet Keep Dripping?
Bathroom faucets get more use than kitchen faucets. The constant turning on and off causes parts to wear out over time. Hot and cold water also makes rubber parts break down faster. A leaky bathroom faucet usually needs a new washer or cartridge.
Identifying Your Faucet Type
Before you start your DIY faucet repair, you need to know what type of faucet you have. This helps you get the right replacement part.
Compression Faucets
- Have two handles (one for hot, one for cold)
- Use rubber washers and tap washers
- Common in older homes
- Easy to fix with basic tools
Cartridge Faucets
- Can have single handle or double handle design
- The cartridge controls the flow of hot and cold water
- Replace the cartridge to fix most leaks
Ceramic Disk Faucets
- Usually have one handle
- Very durable but need special seals
- Less common but long-lasting
Ball Faucets
- Single handle design
- Complex inside with ball bearings and springs
- Most common in kitchen sinks
Tools and Materials You’ll Need for Faucet Leak Repair
Basic Tools List:
- Adjustable wrench
- Screwdriver (both flathead and Phillips)
- Needle-nose pliers
- Cloth or towel
Faucet Repair Kits and Replacement Parts
Most hardware stores sell repair kits for each faucet type. These kits include:
- New washers and o-rings
- Replacement cartridge
- Plumber’s grease
- Basic instructions
Washer Replacement for Faucet
The rubber washer sits at the bottom of the stem. When this washer gets worn-out, water drips from the spout. Measure your old washer to get the right size replacement part.
Faucet Cartridge Replacement
A cartridge controls water flow in many modern faucets. If your faucet still drips after replacing washers, you likely need to replace the cartridge.
Step-by-Step Guide: How to Fix a Drippy Faucet
Step 1 – Turn Off the Water Supply
First, shut off the water supply. Look for the shut-off valve under the sink. Turn it clockwise to stop water flow. If you can’t find the valve under the sink, use your home’s main shutoff valve.
After you shut off the water, turn on the faucet to drain any remaining water in the line.
Step 2 – Plug the Drain to Avoid Losing Parts
Put a cloth or towel in the drain. This prevents small screws and washers from falling down the pipe. Small parts are hard to replace if you lose them.
Step 3 – Disassemble the Faucet Handle
Remove the faucet handle first. Look for a top screw that holds the handle in place. Some handles have decorative caps that hide the screw.
Use your screwdriver to unscrew the handle. Then unscrew the packing nut behind the handle. This gives you access to the faucet stem.
Step 4 – Inspect and Diagnose the Problem
Once you remove the handle, look at all the parts. Check the:
- Rubber washer at the bottom of the stem
- O-ring behind the handle
- Cartridge (if your faucet has one)
- Valve seat where the stem sits
Look for cracks, tears, or mineral buildup on these parts.
Step 5 – Replace Worn Washers, O-Rings, or Cartridges
Replace any worn-out parts you found. Make sure your replacement part matches exactly. Even small differences can cause the faucet to leak.
For compression faucets, replace the rubber washer and o-ring. For cartridge faucets, you may need to replace the cartridge entirely.
Step 6 – Clean and Lubricate Faucet Parts
Before you reassemble the faucet, clean all parts with warm water. Remove mineral deposits with white vinegar. Put a small amount of plumber’s grease on threads and moving parts.
Step 7 – Reassemble the Faucet and Test for Leaks
Put everything back together in reverse order. Don’t over-tighten screws – this can damage threads or crack parts.
Turn the water supply back on slowly. Check for leaks around the handle and spout. If you still see drips, you may need to loosen and retighten connections.
