You’ve turned off the faucet, walked away, and yet… drip, drip, drip. Or maybe your bathtub’s faucet keeps running water long after you’ve finished your bath. Besides being irritating (and a little hypnotic if you stare too long), a persistent leak wastes water, drives up your bill, and could be a sign that something in your plumbing system needs attention.
Let’s break down the most common reasons why a faucet or bathtub keeps leaking and why, sometimes, calling a plumber is your best move.
1. Worn-Out Washers or O-Rings
Inside every faucet are small but mighty components called washers and O-rings. Over time, these parts can wear down from friction and constant use. When they no longer fit snugly, water can slip through even when the handle is off.
Signs this might be the issue:
- The drip is steady but not a full stream.
- The leak seems to come from the spout, not the base.
Fix:
If you’re handy with basic tools, replacing a washer or O-ring can be a DIY job. But keep in mind the exact size and type need to match your faucet model. A plumber can not only replace the part quickly but also check for other wear that could cause future leaks.
2. Corroded Valve Seats
The valve seat connects the faucet to the spout. If it corrodes due to mineral buildup or rust, it can create gaps where water seeps through.
Why it happens:
Hard water is often the culprit here. Over time, minerals accumulate and break down metal parts inside the faucet.
Fix:
Cleaning or replacing a valve seat isn’t overly complicated, but it does require disassembling the faucet. If you’re not comfortable taking your plumbing apart, a plumber can get it done in a fraction of the time without the risk of damaging the fixture.
3. High Water Pressure
If your water pressure is too high, it can force water past seals and gaskets even after the faucet is off. In bathtubs, high pressure can keep water trickling from the spout for minutes (or longer) after you’ve closed the valve.
Signs this might be the issue:
- The drip stops and starts at random times.
- Multiple faucets in the house seem to leak.
Fix:
A plumber can test your water pressure and, if needed, install a pressure-reducing valve to protect your plumbing Idaho Falls system.
4. Worn-Out Cartridge or Stem
Many modern faucets use cartridges or stems to control water flow. These parts have seals that wear down over time, letting water slip through even when the handle is closed.
Signs this might be the issue:
- The faucet is harder to turn on or off than usual.
- Water keeps flowing for a few seconds after you shut it off.
Fix:
Replacing a cartridge or stem is usually straightforward for someone who knows the model. A plumber can identify the right replacement and install it correctly, ensuring the leak actually stops.
5. Problems Specific to Bathtub Faucets
Bathtub fixtures often develop a slow trickle due to worn-out diverter valves (the part that sends water to the showerhead) or issues with the hot/cold mixing valve. These parts can wear out faster if you have hard water or use the tub frequently.
Fix:
Bathtub faucet repairs often involve shutting off water to the whole bathroom and disassembling larger parts. This is one of those cases where calling a plumber can save you hours and spare you from any unexpected water gushes.
Why You Shouldn’t Ignore It
A small drip might not seem urgent, but it can waste gallons of water every day. Over weeks or months, that adds up on your water bill, not to mention the wear and tear on your plumbing. Plus, leaks can sometimes indicate bigger problems in your water lines or valves that need fixing before they become expensive repairs.
When to Call Plumbing Idaho Falls
If you’ve tried tightening handles, replacing washers, or checking for visible issues without success, it’s time to bring in a professional. A plumber has the tools and experience to diagnose the cause quickly, replace worn parts, and make sure your faucet or tub stops wasting water.
Bottom line: Fixing a leak early not only saves water and money but also protects your home from potential water damage. So if that drip, drip, drip is driving you crazy or just won’t stop — don’t wait. Your future self (and your water bill) will thank you.
