Why Is My Grohe Bathroom Faucet Leaking Under the Sink?
A leak under the sink usually points to issues with the supply lines or mounting connections rather than the faucet body itself. Here are the most common reasons:
- Loose supply line connections: Over time, the hot or cold water connections can loosen and drip.
- Worn or cracked hoses: Flexible hoses under the sink may degrade with age.
- Faulty O-rings or gaskets: Small rubber seals can wear out, leading to leaks around fittings.
- Improper installation: If the faucet wasn’t tightened correctly, leaks may develop later.
- Internal cartridge issues: Rare, but water can travel down the faucet body if a cartridge fails.
How to Fix a Grohe Faucet Leaking Under the Sink
- Shut off water supply: Close both hot and cold shutoff valves under the sink.
- Dry the area: Use a towel so you can identify where water is coming from.
- Check supply lines: Tighten connections with an adjustable wrench. If hoses are damaged, replace them.
- Inspect O-rings and gaskets: Replace any worn rubber seals with Grohe-compatible parts.
- Check mounting hardware: Tighten the faucet’s mounting nuts to ensure a snug fit.
- Test for leaks: Turn water back on and check carefully under the sink.
Pro Tip: If your faucet is more than 10 years old, it may be more cost-effective to replace it with a new model rather than repeatedly repairing leaks.
Preventing Future Leaks
- Replace supply lines every 5–10 years to prevent failure.
- Inspect under-sink connections yearly for signs of wear.
- Use only genuine Grohe parts for replacements.
- Hire a professional plumber if you’re not comfortable with DIY fixes.
