Fix a Leaky Bathtub Faucet

The bathroom is the only place in your home with lots of plumbing fixtures. So, it is not surprising that most water leakage happens in this area. But many people don’t notice their bathtubs leaking until much later. This can cause severe damage and problems like mold growth.

Some people pay little attention to dripping bathtubs. They must be made aware that around 3000 gallons of water are wasted annually. If you see that your bathtub faucet is leaking, you need to stop the leakage right away.

    5 Common Causes of Faucet Leaks

    fix a leaky bathtub faucet-Bathtub Faucet

    Because bathrooms have a lot of plumbing, it’s hard for most homeowners to figure out where the leak is coming from. Water moves around easily and can move through pipes before it drips. If you want to stop a faucet from leaking, you should first find out where the leak is coming from. The following are some of the reasons why faucets leak:

    Dripping Tub Spout

    The most frequent cause of dripping bathtubs that is also the easiest to repair is a leaky faucet. Even though it catches all the drips and stops the floor from getting wet or mildew from growing, most homeowners don’t think this is a big deal.

    But every homeowner should take any leak seriously.

    This is because leaky faucets raise water bills. Also, drips that don’t stop will wear away the area they touch, leaving behind ugly mineral stains. Most of the time, changing the rubber washers will quickly fix a leaky faucet.

    Leaking Drains

    Water seepage in your tub faucet might also be caused by leaking drains. The professional plumber involvement is necessary for leaks that develop under the drain. However, incorrectly installed seals during assembly can also lead to leaking drains. If so, you can solve the problem without buying new supplies. Search for and watch videos on safely removing and fixing the drain to accomplish this.

    Problems with Grout

    Most tub leaks are caused by shrinking grout around tiles, particularly where shower water is applied, rather than inadequate drainage or pipes. Shower water pressure frequently strikes and penetrates behind bathroom tiles. Due to the water pooling, most homeowners think they have a significant issue with their bathrooms.

    Broken Tub

    If your tub faucet leaks, it is clear there is a crack. Some cracks are as thin as a hairline, which makes them hard to see, especially if the water you see is coming from the tub’s faucet body.

    Leaking Overflow Pipe

    Leaks can also be caused by overflow pipes, which are usually at the back of tubs. If the washers between the tub faucet and the overflow pipe are dry or cracked, the overflow pipe may leak. Unlike faucet washers, these washers are sealed into the wall, which makes it hard to change them. Because of this, it’s best to get help from a professional plumber.

    Steps on Fixing a Leaking Bathtub Faucet

    Most of the time, leaking bathtub faucets are caused by an old washer. If your tub has a leaky bathtub faucet due to an old washer, follow the steps below on how to fix it. But, before that, you have to prepare the tools listed below that you will need:

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

    These tools are readily available at a hardware store.

    Keep in mind that most bathtubs, including walk-in and corner bathtubs, can be fixed using these step-by-step instructions. For freestanding tubs, the steps are a bit different.

    Step 1: Cut Off the Water Supply

    Before you start doing anything with your faucet, you should turn off the water supply first. Skipping this part would lead to a water overflow in your bathroom. Most of the water supplies in residential areas have valves you can turn off. Look for that and turn it off so you can start fixing your leaking bathtub faucet.

    If there is no shut-off valve in your bathroom, you have to turn off the water supply to your entire house so you can continue to the next step.

    Step 2: Take Off the Faucet’s Cap

    Pry off the lid covering the faucet handle screw. You can use a slotted screwdriver or a small pocket knife to remove the screw.

    To remove the cap, use your preferred tool to pry it off after fully opening the faucet to drain any remaining water (just as you would if you were running the water). Put it away in a secure place where you can find it later.

     Step 3: Remove the Screw Handle

    After removing the cap and exposing the screw of the faucet handle that keeps it in place, you need to remove it using a screwdriver. Place the unscrewed screw and the cap in a safe place so you can easily reach for them later.

    Now remove the handle. This step is tricky, as the process of removing the handle will depend on your faucet system and how old your faucet is.

    Step 4: Remove the Handle

    Now that you have removed the screw, you can easily take off the handle. The removal of the handle will depend on how old your faucet is. You might not notice from the outside, but there could be water deposits and corrosion on the inside, which might cause the fusing of the handle into the stem.

    If you have difficulty removing the handle, do not force it as it might break. There are tricks that you can apply that will help you remove them. You can pour hot water over it or use a hair dryer to warm the handle to loosen it. White vinegar is also helpful in removing a fused handle.

    If this trick does not help at all, you can use a handle puller to remove the handle. A handle puller is a unique tool made specifically for this purpose.

    Step 5: Escutcheon and Stem Assembly Removal

    The plate covering the hole in your bathroom wall, known as the escutcheon, must be removed next. You could need to unscrew it or twist it off, depending on the style of your faucet.

    When you take off the escutcheon, it’s easy to get to the stem assembly, which is what you need to stop the leak. An adjustable bath socket wrench makes it easy to take the stem bonnet off the stem or bonnet threads.

    Step 6: Examine and Change the Worn-Out Washer

    fix a leaky bathtub faucet-Change-the-Worn-Out-Washer

    As previously indicated, a worn-out seat washer may be the primary cause of your leaky faucets. Start by inspecting the seat washer after removing the faucet’s stem assembly. Old washers frequently appear brittle and distorted.

    If your old washer looks like this, think about switching to a new washer. Check your seat washer screw, and unscrew it from the faucet’s stem assembly to replace the stem bonnet washer.

    Make sure to check the faucet seat for any indications of potential damage before changing the faucet stem assembly. Make sure to replace a rubber washer if there are obvious signs of wear. You might need a seat wrench or a bath socket wrench, which are specialized tools for this task.

    Step 7: Examine the Seat for Damage

    The seat could be destroyed, which is yet another reason why you might be experiencing a leak. The component in contact with the washer is the seat, which may sustain damage due to corrosion or washer wear.

    A cracked seat may leak on its own, and it may also swiftly harm the replacement washer you just installed, making the leak come back.

    Because of these things, you should also check the seat for signs of damage before you put the stem assembly back together with the new washer. 

    Step 8: Replace the Seat, If Needed

    You must take out and replace the seat if you notice any symptoms of damage. Use a seat wrench, a specialized tool designed for this job, to remove the seat.

    Step 9: Reassemble the Faucet

    You should then carefully disassemble everything before reassembling it in the proper order. Replace the stem assembly first, then tighten it with the adjustable wrench. Screw the handle first, then the handle and cap, and finally the escutcheon. Once everything is in place, turn back the water supply and turn on the faucet to test how the water flows.

    Congratulations if the water works properly and the faucet stops leaking. You can try these methods again or speak to a plumbing expert if the issue continues.

    Additional Tips When Fixing a Leaky Bathtub Faucet

    fix a leaky bathtub faucet-Check Your Bathtub Faucet

    When repairing a leaky tub faucet, take into account the following advice:

    Identify the Ideal Tightness

    Make sure everything is secure but not too tight when you reassemble the faucet. The components are now simple to disassemble in the future.

    Examine the faucet

    If your faucet has two handles, you can easily tell if it is leaking hot or cold water because you can just feel it. This can help you determine which faucet needs to be fixed.

    Check Your Bathtub Faucet Frequently

    Paying close attention is the only way to determine whether your plunge bath is dripping. You should check your bathroom’s various parts on a monthly basis, especially the faucets and the bathtub. Watch out for unwelcome puddles, drips, mineral buildup, and stains on the faucet’s collar. If you spot any, attempt to identify the cause so you can fix the issue right away.

    Why Does My Bathtub Faucet Drip When the Water is Turned Off?

    If your faucet drips water even after you turn it off, there may be a loose or defective seat washer to blame. Washer problems frequently cause leaking sink faucets. With use, the seat washer screw can become loose, causing the faucet to drip or chatter.

    How Do You Reseal a Bathtub Faucet?

    Resealing a bathtub faucet is easy. Follow the steps below:

    1. Uninstall the Old Caulk

    Use a utility razor edge or knife to break the seal between the caulk, the spout, and the tub. Hold the razor or knife at an angle to make it less likely that you will damage the bath.

    2. Remove the Caulk

    Push the caulk inward with the knife or razor to release it. Cut a line through the caulk. Take hold of the end and begin to pull. Most caulk needs to dispense in a lengthy strip. Any residual caulk can be scraped away with your knife or razor.

    3. Wash the Wall and Spout

    To clean the wall and spout, gently saturate a rag in a solution of 1 part bleach and 3 parts warm water. Shower caulk needs a clean surface in order to create a watertight seal. A wet cloth shouldn’t be used since it can leak water beyond the wall.

    4. Fill Your Caulking Gun With Caulk

    After inserting the caulking tube, secure it in the caulking gun. Trim off about 1/2 inch of the tube’s tip with a utility knife by cutting at a 45-degree angle. Use a nail to pierce the tube’s nozzle and allow the caulk to flow to make caulking around the tub spout easier.

    5. Caulk Around the Spout

    When you see the caulk erupting from the tip of the caulk gun, pull the trigger. Using a rag, take off the caulk, and then put the tip of the tube where the bath spout and the wall connect. After putting the trigger back in place, move the caulk gun around the end of the spout. You need to stop and start a few times before you can complete the circuit around the spout. As long as the new bead starts to touch the old one, stopping is acceptable.

    6. Spread and Flatten the Caulk

    Utilize a damp finger to run it along the caulk bead. By doing so, you can spread and flatten the caulk, giving it a cleaner appearance and creating a tighter seal. Additionally, it evens out any areas of caulk where you may have stopped and started. With a rag, wipe the caulk off of your finger.

    7. Let the Caulk Dry

    Use the bath spout after letting the caulk set for at least 24 hours.

    How Do You Fix a Bathtub Faucet that Won't Stop Running?

    The two most popular reasons why the bathtub faucet won’t stop running are that the valve needs a replacement or the faucet handle is damaged. You must first identify what causes this problem before you can start fixing it. Below are steps on how to fix your bathtub faucet that won’t stop running:

    1. Before you begin working, put on your gloves and safety glasses.
    2. Make sure that the main water supply valve is closed. This is either in your garage or basement, as was previously mentioned.
    3. With a flat-blade screwdriver, push off the cover plate from underneath to expose the handle screw. The handle screw should be tightened with a Phillips screwdriver.
    4. Reopen the main water valve and test the faucet to check if the problem has been resolved.

    If the above steps do not work, do the steps below:

    fix a leaky bathtub faucet-Fix a Bathtub Faucet
    1. Reverse the main water supply shutoff. The handle can be taken off the stem by rotating it to the right. This may require the use of a wrench or a light pull.
    2. Check the stem of the faucet for any problems. There are ridges in the stem. If these are worn down, the stem cannot grab the faucet.
    3. Remove any deposits and debris from the stem with an old toothbrush, and then dry the stem.
    4. Wrap a couple of thicknesses of thread seal tape around the valve stem tip. The handle should then be placed over the stem through the tape. Another method is to turn the handle over the stem and let it lock.
    5. Keep in mind that this is only a temporary solution. The faucet handle will need to be replaced after a month or up to two years.

    Can You Fix a Leaky Faucet Without Turning Off the Water?

    A faucet can be changed without turning off the water, yes. Your chances of success will depend on how fast you can work and how much water pressure is at the fixture.

    Do You Have to Shut Off the Water to Change Bathtub Faucet?

    Generally, yes, you need to shut off the water to change the bathtub faucet successfully. But some people managed to change the faucet without shutting it off. So, it all depends on you and how skilled you are at changing the bathtub faucet.

    How Do You Temporarily Stop a Leaky Faucet?

    Temporary faucet fixes include wrapping a string around it and making sure it passes over the spout or the aerator. Allow the string’s tail to hang down to the sink after that. The string will catch the water as it drips and send it quietly down the drain.

    How Do I Stop a Dripping Faucet?

    The steps for stopping a dripping faucet are simple. Follow the steps below:

    • Turn off the shutoff valve. If it does not have one, turn off the main water supply.
    • Disassemble the faucet handles. This step will depend on the type of faucet you have.
    • Remove the valve stem. Brass valve stems on compression faucets can be unscrewed, while on cartridge faucets, you can remove them easily.
    • Check the different parts of the faucet and determine which one will require replacement.
    • Replace the damaged parts.
    • Remove any mineral build-up on the body. You can use white vinegar to clean the valve seat.
    • Reassemble the faucet once you have the new replacement parts and have cleaned everything. In order to check for leaks, turn on the water supply.

    Why Does My Shower Drip Hours After I Turn It Off?

    Most of the time, your shower control washers have been compromised. If your shower leaks water even when it’s turned off, the controls are probably letting water out. When the shower valve is closed, there should be a seal that keeps water from going through the control to the shower head.

    How Much Does it Cost to Fix a Leaking Bathtub Faucet?

    A bathtub faucet typically costs between $300 and $450 to replace or repair, with an average cost of $350. However, you might have to spend up to $1,000 to completely replace a faucet or just $50 to make a little fix.

    Why Does My Shower Drip When I Run the Bath?

    A leaky showerhead is typically caused by deteriorated or worn inner seals. Your shower’s rubber washers or O-rings serve as a seal between your showerhead and shower hose to stop water leaks. These degrade over time, and water begins to flow out when they do.

    Why Does Tub Faucet Leak When Shower is On?

    The diverter is broken when the shower is running, and water is coming out of the tub spout. To vary the direction of the water flowing up to the shower head, most faucets either employ a diverter or a third handle in the center of the faucet.
