A leaking bathtub faucet isn’t just an annoyance, it’s like money dripping down the drain. Every drip adds up, not just in wasted water but in increased water bills. What seems like a minor inconvenience can quickly turn into a costly problem if left unchecked.
So, why does your bathtub faucet leak? There are a few common causes, including worn-out washers, a worn-down faucet stem, damaged cartridges, or loose parts.
In this article, we’ll explore each of these causes, how you can fix them, and when it might be time to call in a professional plumber.
Key Takeaways
- A leaking bathtub faucet can waste water and hike up your bill.
- Most leaks are caused by worn washers, faucet stems, broken cartridges, or loose parts.
- Simple repairs like cleaning or replacing parts can often fix the issue.
- If repairs don’t stop the drip, a replacement or a call to the pros may be necessary.
What Causes a Bathtub Faucet to Leak?
Bathtub faucets are a mix of small parts working together to control water flow. When even one of these parts is worn or damaged, you’ll experience leaks. Let’s take a closer look at what could be causing that pesky drip.
Worn Down Washer
The washer is a rubber or silicone ring that presses against the faucet bed to create a seal. Over time, the constant pressure and friction wear it out. Once that happens, water starts slipping past the seal, causing a leak.
Worn Down Faucet Stem
The faucet stem controls the flow of water into the tub. When it’s in good shape, you turn the faucet handle, and water flows smoothly. But as it wears down, water can start leaking through small gaps, even when the faucet is off.
Broken Cartridge
The cartridge inside your faucet is what turns the water on and off while also controlling the temperature. A broken or damaged cartridge throws off that balance, and you might notice water leaking from the faucet even when it’s in the off position.
Loose Parts
Sometimes, leaks aren’t due to worn-out parts but simply loose ones. Improper installation, age, or just plain wear and tear can loosen the internal components of the faucet. A loose screw or an unfastened washer can cause water to leak, so it’s worth checking all parts for tightness.
How to Fix a Leaking Bathtub Faucet
Once you’ve identified the source of the leak, it’s time to roll up your sleeves and get to work. Below is a step-by-step guide to fixing your bathtub faucet leak, depending on which part is causing the issue.
Turn Water Off
First things first, you’ll want to shut off the water supply. Nothing’s worse than starting a repair and suddenly having water gushing everywhere. After shutting off the valve, turn on the faucet to drain any remaining water from the pipes.
Remove Tub Faucet
Next, it’s time to take off the faucet. You’ll need a screwdriver to unscrew the cover and handle. It’s usually pretty straightforward, though it might take a bit of elbow grease to get it started. After removing the handle, you’ll have access to the parts that might be causing the leak.
Remove Cartridge
If you suspect the cartridge is the issue, you’ll need a special cartridge removal tool. Don’t worry—it’s often included with the new cartridge, or you can grab one at the hardware store. Use the tool (or a pair of pliers) to carefully remove the cartridge. If it’s cracked or broken, it’s time for a replacement.
Look for Loose or Damaged Parts
As you’re removing the faucet, check all the faucet parts, especially the washer and the faucet seat. The washer and seat work together to prevent leaks, so any damage or wear in this area could be the root of your problem.
Soak Parts in Vinegar
Mineral buildup from hard water is another common issue that can cause leaks. To clean it up, soak the faucet parts in a vinegar-water solution. Depending on how bad the buildup is, this could take anywhere from a few minutes to an hour. Once they’re clean, you can put everything back together and see if the leak has stopped.
You’re Better Off Leaving To The Pros
Sometimes, even with the best intentions, things don’t go as planned. Maybe the leak persists, or you can’t seem to get the parts to fit back together. That’s when it’s time to call in the pros. If you’re having trouble with persistent leaks, difficulty removing parts like the faucet stem, or just feel unsure about your home’s plumbing system, it might be best to leave it to an expert.
