Common Reasons Why Faucets Leak or Need Repairs

Faucets are essential fixtures in our homes, ensuring a steady flow of water for various daily activities. However, they can sometimes misbehave, and one common issue is leaking. Understanding the reasons behind faucet leaks is crucial for effective troubleshooting and preventing potential water wastage. Let’s explore common reasons why faucets tend to leak.

Dripping Tub Spout

A prevalent and often overlooked cause of bathtub faucet leaks is a worn-out rubber washer. Visualize the rubber washer as a tiny, hardworking band within the faucet mechanism. Over time, this washer undergoes wear and tear due to constant use and exposure to water. When the washer becomes tired, it loses its ability to form a tight seal, resulting in those annoying drips.

These seemingly harmless droplets, if left unaddressed, can lead to increased water bills and unsightly mineral stains. Fortunately, addressing this issue is relatively straightforward. Replacing the rubber washer can effectively put an end to the persistent dripping and restore the faucet’s efficiency.

Leaking Drains

Another potential culprit behind a leaky tub faucet is related to the drainage system. Water seepage may occur around the drains, causing unexpected leaks. While professional plumber intervention may be necessary for leaks originating beneath the drain, there’s a possibility that you can resolve the issue without investing in new supplies.

Often, leaks around drains can result from improperly installed seals during the assembly process. Fortunately, learning how to safely remove and fix the drain by watching instructional videos can empower you to tackle this problem independently.

Problems with Grout

Surprisingly, the grout around tiles, particularly where the shower water hits, can contribute to tub leaks. This might seem counterintuitive, as one might associate leaks with inadequate drainage or pipe issues. However, the force of shower water can penetrate behind bathroom tiles, causing grout to shrink.

Homeowners may mistakenly perceive this as a more severe problem than it actually is, thinking they have significant issues with their bathroom. Recognizing that shrinking grout is a common cause of leaks allows for a more accurate diagnosis and targeted solutions. Addressing grout problems, such as resealing, proves to be a more effective approach in such cases.

Broken Tub

A visibly leaking tub faucet signals a more apparent issue – a crack in the tub. These cracks can be as thin as a hairline, making them challenging to detect, especially when the water appears to be coming from the faucet body. Nevertheless, even the slightest crack can be a source of trouble, leading to persistent leaks.

Identifying and addressing these cracks promptly is crucial to preventing further damage. The challenge lies in the subtlety of these cracks, requiring homeowners to be vigilant and proactive in their inspections.

Leaking Overflow Pipe

Less commonly known but equally impactful are leaks originating from the overflow pipe, typically located at the back of tubs. Unlike faucet washers, the washers between the tub faucet and the overflow pipe are sealed into the wall. This makes them challenging to replace, necessitating professional plumbing assistance.

When the washers between the tub faucet and the overflow pipe become dry or cracked, the overflow pipe may start to leak. Detecting and addressing these leaks require specialized knowledge and tools, emphasizing the importance of seeking professional help in such instances.

Understanding the various reasons why faucets, particularly tub faucets, may leak is fundamental to effective troubleshooting and timely repairs. From worn-out rubber washers to issues with drainage and grout, each cause requires specific attention and targeted solutions.

You can empower yourself by familiarizing with these common reasons, and take proactive measures in maintaining a leak-free bathroom. Now, let’s get to the part where we learn how to repair a tub faucet.

Steps to Follow: How to Repair a Tub Faucet

Leaky bathtub faucets are a common household nuisance that can lead to increased water bills and potential water damage. Addressing this issue promptly not only saves resources but also prevents more extensive plumbing problems.

So, without further ado, let’s learn how to repair a tub faucet:

Tools You’ll Need

Before embarking on the repair journey, gather the following tools, which are readily available at most hardware stores:

• Adjustable wrench
• Flathead screwdriver
• Handle puller
• Packing nut
• Screws
• Seat wrench
• Spanner
• Vice grip

Ensuring you have these tools at hand will streamline the repair process and help you tackle any unforeseen challenges.

Step 1: Cut Off the Water Supply

The first and crucial step regarding how to fix a bathtub faucet is cutting off the water supply. To do this, locate the water supply valve, often found beneath the sink or near the tub. Turn the valve clockwise to shut off the water supply. This prevents any potential water overflow during the repair process.

In some cases, residential areas may have shut-off valves specifically for individual fixtures. If your bathroom lacks a shut-off valve, you might need to turn off the water supply to the entire house. Locate the main water supply valve, usually situated in the basement or garage, and turn it off.

Step 2: Take Off the Faucet’s Cap

Once the water supply is secured, it’s time to access the inner workings of the faucet. Most faucet handles have a cap covering the handle screw. Use a slotted screwdriver or a small pocket knife to carefully pry off this cap. Ensure you fully open the faucet to allow any remaining water to drain.

After successfully removing the cap, set it aside in a secure place where you can easily retrieve it later.

Step 3: Remove the Screw Handle

With the cap off, you’ll now see the faucet handle screw exposed. Use a screwdriver to remove this screw, keeping both the screw and the cap in a safe location. The next challenge is removing the handle itself.

The process of removing the handle can vary based on your faucet system and its age. Older faucets might have water deposits and corrosion on the inside, making the handle stick to the stem. If you encounter difficulty, avoid forcing the handle, as it may break.

To facilitate handle removal, you can try pouring hot water over it or using a hairdryer to warm the handle, loosening it from the stem. Alternatively, white vinegar can help dissolve mineral deposits, aiding in the removal process. If these tricks prove ineffective, a handle puller, a specialized tool designed for this purpose, can be used.

Step 4: Escutcheon and Stem Assembly Removal

With the handle successfully removed, the next step is taking off the escutcheon, the plate covering the hole in your bathroom wall. Depending on your faucet’s style, you might need to unscrew or twist off the escutcheon.

Once the escutcheon is off, you’ll gain access to the stem assembly, the critical component that needs attention to stop the leak. An adjustable bath socket wrench is a handy tool for easily removing the stem bonnet from the stem or bonnet threads.

Step 5: Examine and Change the Worn-Out Washer

The primary cause of a leaky faucet is often a worn-out seat washer. Inspect the seat washer after removing the faucet’s stem assembly. Old washers commonly appear brittle and distorted, indicating the need for replacement.

If the old washer shows signs of wear, unscrew it from the faucet’s stem assembly and replace it with a new one. Ensure the faucet seat is also in good condition; if you notice any damage, replace the rubber washer accordingly. Specialized tools such as a seat wrench or a bath socket wrench might be necessary for this task.

Step 6: Examine the Seat for Damage

In addition to replacing the washer, it’s essential to examine the seat, the component in contact with the washer. Damage to the seat can occur due to corrosion or wear from the old washer. A cracked seat can lead to independent leaks and hasten the deterioration of the newly installed washer.

Before reassembling the faucet, thoroughly inspect the seat for any signs of damage. If damage is detected, use a seat wrench, a specialized tool for this job, to remove and replace the seat.

Step 7: Replace the Seat, If Needed

If you find any indications of damage during your seat inspection, it’s crucial to remove and replace the seat. Employ a seat wrench, specially designed for this task, to remove the damaged seat and install a new one in its place.

Step 8: Reassemble the Faucet

With the new washer and, if necessary, seat in place, you can proceed to reassemble the faucet. Carefully reverse the disassembly process, starting with the stem assembly. Use an adjustable wrench to tighten the stem assembly, securing it in place.

Screw on the handle, followed by the handle screw and cap. Finally, reattach the escutcheon, ensuring everything is snug and secure. Once the faucet is reassembled, turn the water supply back on and test the faucet to observe the water flow.

And that’s all there is to know on how to repair a tub faucet. Congratulations if the water flows smoothly without any leaks. However, if the issue persists, you may need to revisit the steps or seek assistance from a plumbing professional.

Additional Tips for Successful Faucet Repair

Fixing a leaking bathtub faucet involves more than just replacing washers and seats. Consider the following additional tips for a successful repair:

Identify the Ideal Tightness

When reassembling the faucet, ensure that everything is securely tightened but not excessively tight. Striking the right balance ensures that components are easy to disassemble in the future, facilitating maintenance.

Examine the Faucet

If your faucet has two handles, you can easily identify which one is leaking hot or cold water by feeling it. This knowledge helps pinpoint the specific faucet that requires attention during the repair process.

Check Your Bathtub Faucet Frequently

Prevention is key to avoiding extensive faucet issues. Regularly inspect your bathroom, especially the faucets and bathtub, on a monthly basis. Keep an eye out for unwelcome puddles, persistent drips, mineral buildup, and stains on the faucet’s collar. Detecting these issues early allows for swift identification and resolution.
