How to Stop a Bathtub Faucet from Leaking
A leaky bathtub faucet isn’t just an annoying drip in the background. Every drop adds up, wasting gallons of water and increasing your overall water bill. Left unrepaired, it can even lead to water damage and mold growth, turning a small issue into a costly problem. Let’s dive into how to fix a leaking bathtub faucet and why prompt action is crucial.
Causes of a Leaking Bathtub Faucet
A leaking bathtub faucet can result from several common issues. Often, the culprit is a worn-out washer, a tiny rubber or metal component that seals the faucet stem. Over time, washers degrade from constant water pressure and need replacement.
Other causes may include:
- Faulty cartridges in single-handle or two-handle faucets that struggle to control water flow.
- Corrosion in faucet parts or the valve stem caused by hard water and buildup.
- Loose or broken o-rings and seals.
- A damaged diverter in shower faucet setups that directs water to the shower head.
Signs of these issues:
- Persistent dripping
- Reduced water pressure
- Difficulty turning off the faucet completely
Identifying the cause first will guide the rest of your repair process…
Step-by-Step Guide to Fixing a Leaking Bathtub Faucet
Repairing a leaky bathroom faucet is a manageable and easy fix for most homeowners. Follow these steps to stop the drip!
Step 1: Shut Off the Water Supply
Before you start, locate and turn off the water supply. This can be done using the water shut-off valve near the bathtub or your home’s main water heater supply valve. Failing to do this could result in water flooding your bathroom during the repair.
Step 2: Disassemble the Faucet
Next, use a Phillips screwdriver or Allen Wrench to remove the faucet handle. Be cautious when handling small screws to avoid losing them. Once the handle is off, you may need to remove the escutcheon plate (the decorative piece around the handle) and other components to access the valve stem.
If you’re unsure which tool to use, check the faucet’s make and model for compatibility. For Delta faucets, for instance, you might need specific faucet parts.
Step 3: Inspect and Replace Faulty Parts
This is where you assess the cause of the leak. Common problem areas include:
- Rubber washers: Look for signs of wear or cracking.
- Cartridges: Remove and inspect for damage or corrosion. Replace with a new cartridge appropriate for your faucet style.
- O-rings: Evaluate these rubber seals for cracks or stiffness.
- Valve stems: For severe leaks, replacing a damaged valve stem might be necessary.
Take the old parts to a hardware store, such as Home Depot, to ensure you get the right replacement parts.
Step 4: Reassemble and Test the Faucet
After replacing faulty components, it’s time to reassemble the faucet. Reverse the disassembly steps and tighten everything carefully. Apply teflon tape around the threads where necessary to ensure a secure seal.
Turn the water supply back on and test both the cold water and hot water sides. If the leak persists, double-check for missed or improperly installed components.
When to Call a Professional Plumber
Sometimes, even the best DIY efforts won’t stop a stubborn leak. Here’s when it’s time to seek professional help:
- The leaky bathtub faucet continues after you’ve replaced parts.
- The shower valve or internal components are difficult to reach.
- You notice extensive water damage or signs of mold around the tub spout or faucet.
- You’re unsure about repairing a single-handle bathtub faucet or two-handle design.
Contacting a plumber ensures you avoid further complications and protects your plumbing system from additional damage.
