A dripping faucet is a common household annoyance. But while a drip from the spout is usually simple, a faucet leaking from handle is a different problem entirely. When water pools around the handle every time you use the sink, the internal seals have failed.
This type of leak only gets worse over time. It can damage your faucet’s finish and cause corrosion. Water can seep into the cabinet below, causing damage and mold growth.
At Repipe Solutions Inc., we know even small leaks create big problems. This guide explains what causes water leaking from faucet handle areas and how to stop it.
The Culprit: Failed Cartridge or Worn O-Rings
Modern faucets use an internal valve called a cartridge to control water flow. The handle attaches to the cartridge stem. Rubber seals called O-rings prevent water from escaping around this stem.
When you turn on the faucet, water flows up into the cartridge and out through the spout. The O-rings keep water from leaking around the handle base. Over thousands of uses, these O-rings wear out, crack, or become dislodged.
When an O-ring fails, water escapes around the cartridge stem. You end up with a puddle forming every time you use the faucet. Whether you have a single handle faucet leaking at base or a bathroom faucet leaking from handle, worn seals are usually to blame.
Older two handle faucet leaking issues may involve worn packing material or a faulty valve stem. The principle remains the same: internal seals have failed and need faucet seal replacement.
How to Fix Leaking Faucet Handle: Single-Handle Faucets
Leaky faucet handle repair almost always involves disassembling the faucet and replacing worn parts. Confident DIYers can handle this job.
- Shut off the water. Turn off hot and cold supply valves under the sink.
- Remove the handle. A small set screw holds it in place, often hidden under a decorative cap. Use an Allen wrench to loosen it and lift the handle off.
- Remove the cartridge. You may need to remove a decorative bonnet or retaining nut first. Pull the cartridge straight up and out. Use a cartridge puller tool if it’s stuck.
- Replace the cartridge and O-rings. Replace the entire cartridge for best results. It comes with all new seals. Match your specific faucet model exactly.
- Reassemble the faucet. Install the new cartridge and reassemble in reverse order. Turn water on and test for leaks.
How to Fix a Two Handle Faucet Leaking
A faucet stem leak in older two-handle faucets requires a slightly different approach:
- Shut off the water.
- Remove the handle. Pry off the decorative cap and remove the screw holding the handle.
- Unscrew the packing nut. This nut holds the valve stem in place. Use a wrench to loosen and remove it.
- Remove and replace the valve stem and O-rings. Pull or unscrew the valve stem. Replace O-rings on the stem, or replace the entire unit if corroded.
- Reassemble the faucet.
When to Call a Professional
While leaky faucet handle repair is a common DIY project, sometimes calling a professional makes sense:
- You can’t identify the correct part. Thousands of faucet models exist. Finding the right cartridge can be challenging.
- The cartridge is stuck or frozen. Forcing a stuck cartridge can damage the faucet body. This creates a much more expensive repair.
- The faucet is old and corroded. Old faucets may be difficult to disassemble without causing further damage.
- You’re not comfortable with the repair. A professional completes the job quickly and correctly.
