Why Is My Faucet Leaking? A Troubleshooting Guide
That incessant drip, drip, drip of a leaky faucet isn't just annoying; it's a waste of water and a potential sign of bigger plumbing problems. But before you panic-call a plumber, there's a good chance you can fix this issue yourself. Let's dive into the common causes and how to stop a leaky faucet.
Common Causes of Leaking Faucets
- Worn-Out Washers: Washers are rubber or silicone seals that create a watertight barrier when you turn your faucet off. Over time, friction wears them down, leading to drips.
- Corroded Valve Seat: The valve seat is where your washer rests. Minerals in your water can lead to corrosion or buildup on the valve seat, preventing a proper seal.
- Loose Parts: Various nuts and screws hold your faucet together. If any of those loosen, leaks can start, especially around the faucet handles.
- Damaged O-ring: O-rings are small rubber seals found in some faucet cartridges. When damaged, they can cause leaks around the spout.
- Incorrect Water Pressure: Excessively high water pressure puts extra strain on all your faucet's components, leading to premature wear and potential leaks. If you also experience low water pressure elsewhere in your house, you might want to investigate the cause further. Check out this article for help: why faucet has no pressure ?
How to Fix a Leaky Faucet
Before you start, remember these basic steps:
Step 1: Gather Tools and Supplies: Screwdrivers, pliers, adjustable wrench, replacement parts (specific to your faucet type), plumber's grease.
Step 2: Turn Off the Water: Locate the shut-off valves under your sink and turn them off. Open the faucet to drain any remaining water.
Step 3: Disassemble the Faucet:
- Remove the handle: There's often a set screw, which might be hidden under a decorative cap. Gently pry this cap off if needed.
- Unscrew the packing nut: This sits under the handle and secures the cartridge or stem in place.
- Remove the cartridge or stem: Cartridges often need a special removal tool. Stems are simpler to pull out.
- Inspect the O-ring: Look for cracks or flat spots. If it's damaged, replace it with a new one and lightly grease it.
- Examine the washer: Check for wear and tear. Replace if needed.
- Assess the valve seat: Look for corrosion or mineral deposits. If it's worn, you'll need a valve seat wrench for replacement.
- Tighten any loose parts: Check all nuts and screws for tightness.
- Reverse your disassembly steps: Carefully reassemble the faucet, ensuring that everything is aligned and tightened correctly.
- Turn on the water: Slowly turn the water valves back on.
- Check for leaks: Observe carefully for any new leaks before putting away your tools.
When to Call a Plumber
While many leaks can be DIY-fixed, there are times when calling in a pro is best:
- Extensive Leaks: If water isn't just dripping, but actively leaking or spraying, it might signify a bigger issue with your pipes.
- Unidentifiable Cause: When you've exhausted all the usual culprits and the leak persists, a plumber's expertise can find the true problem.
- Lack of Confidence in DIY Repairs: If you're not comfortable disassembling your faucet, a plumber can save you time and potential further damage.
Preventing Future Leaks
- Regular Maintenance: Visually check your faucets for signs of wear and tear periodically. Tightening a loose screw early on can prevent bigger problems later.
- Addressing High Water Pressure: If you suspect high water pressure is straining your faucets, a pressure regulator can help.
- Choosing Quality Faucets: Investing in well-constructed faucets from reputable brands can extend their lifespan and reduce the likelihood of leaks.

A leaky faucet is a common household problem, but it doesn't have to be a permanent one. With a little knowledge and troubleshooting, you can often solve the issue yourself and conserve both water and money. If in doubt or if a DIY fix isn't working, remember there's no shame in calling in a licensed plumber for help.
