How To Fix a Leaky Bathtub Faucet?


Created At 1 year ago


Over time, leaking faucets can cost you a lot of money in additional water bills, and the water constantly trickling into your tub can leave an ugly stain. You may, however, be afraid to spend money on a plumber because you are aware of their high cost. Repairing a leaking bathtub faucet isn’t that difficult, and you should be able to do it yourself with a few essential tools. If you want to make it a shot, here’s our step-by-step approach to fix a leaky bathtub faucet.

You don’t have to put up with a leaky faucet’s steady drip or the stain it frequently leaves in the tub or shower. Fix it now to avoid problems and to save money on your water bill. The complete procedure, with special equipment, may cost a little money. Still, it’s a lot less expensive than hiring a plumber, and it’s usually far cheaper and more accessible than ripping out the old faucet and replacing it.

Disadvantages of Bathtub Faucet Leaking

Most leaks are caused by worn rubber washers, seals, or gaskets in the valve assembly. We’ll teach you how to repair a stem-type valve, typical in two-handle faucets from the past (separate hot and cold).

Not only can repair your leaky bathtub faucet save you money on your water bills, but it will also prevent unattractive stains from accumulating in your tub. The most common and best source of leaks is a defective washer. Fixing a leaky faucet is a simple task that can be completed with only a few essential tools and a trip to the durable hardware store.

Although one drop of water may not seem like much, a leaky faucet leaking one drop per second can waste almost 3,000 gallons of water each year. That’s enough water to fill more than sixty standard bathtubs! A worn-out washer is the most common cause of a leaking tub faucet. By replacing your old washer with a new one, you can save a lot of money on your water bill. To return your worn-out washer and stop your faucet from leaking, follow these steps from Newcomb and Company.

An outdated washer that has to be replaced is the most typical cause of a leaking faucet. The steps are listed below, and they apply to most types of bathtubs, including walk-in bathtubs, corner bathtubs, and others.

Dripping bathtub faucets can significantly increase your monthly water cost. Many people try to tighten the faucet handles, inadvertently shredding the seals even more. Although significant issues require the services of a plumber, most broken washers, gaskets, and seals repair using a few special tools.

Reason for Bathtub Faucet Leaking

A faucet’s external handle is coupled to a stem—the stem moves when you turn the faucet handle. A tiny rubber washer is attached to the end of the stem with a screw. The pressure on the washer against the seat is released when you turn on the faucet, and water pours.

When you turn the handle to “Off,” the pressure on the faucet seat and washer is restored, and the flow is stopped. The correct pressure cannot apply if the washer or chairs are worn, and water seeps through. Water is dripping from your faucet as a result.

The processes would be slightly different for a standalone bathtub with a separate faucet. If you have a leaking faucet, you know how annoying it is to have a steady sluggish drip and water stains that don’t go away no matter how much you clean them. Fixing the spout as soon as you identify the problem will save you a lot of aggravation and money on your water bill.

A faulty diverter on a spout can cause a less severe problem. As a result, water drips mainly from the spout rather than the showerhead. Although this problem will not do any harm, it can be aggravating.

On the other hand, Spouts can leak up to the point where the spout and the wall meet. It is a significant problem since it has the potential to inflict considerable damage. Leaks can potentially cause significant structural damage to your property, and mold can grow as a result of water damage, posing a health risk. The job will cost you some money, but it will be well worth it. You will save money by repairing the faucet rather than taking it out and replacing it with a new one.

Fix a Leaky Bathtub Faucet

Before you hire a plumber, read this tutorial for step-by-step instructions on how to replace a leaky bathtub spout.

Turn Off the Water Supply:

It’s impossible to perform any repairs while the tub is still filled with water. You may be able to switch off the water from under the sink in some homes. If that isn’t an option in your home, you may need to switch off the house’s primary water supply while working on the repairs. Turn the handles of your bathtub faucet as if you were trying to run a bath once the water is turned off. Before you begin, this thing will drain any extra water from the pipes.


Turning off the water supply is the first step in repairing a leaking bathtub faucet. If you forget, you’ll wind up spraying water all over the place when you try to remove the faucet from its fitting. There may be a simple and elegant valve in your home or apartment that allows you to open the water to the bathtub.

If this is not the case, you will need to cut off the water supply to your entire house before proceeding to the next step — there should be a lever near the water meter that allows you to do so.

Take Off the Faucet’s Cap:

The cap that covers this faucet handle screw must be prayed off next. A little pocket knife or a slotted screwdriver is used for this. First, remove the cap, open the faucet all the way to drain any water (as if you were running the water), and then pry it off with your chosen tool. Please put it in a safe and best place where you’ll be able to find it later.

Remove The Handle Screw:

After removing the cover, look inside the faucet handle for the screw that holds the handle in place. You’ll need to use a screwdriver to remove it now. To avoid losing the screw, unscrew it and place it with the cap. The handle can then be removed after the screw has been removed. This stage can be a little challenging depending on how old your faucet is, as corrosion and water deposits cause the handle to fuse to the stem.

If it doesn’t come off on its own, don’t force it; you might break it. Warming it with hot air from a hairdryer or pouring boiling water over it are two alternatives that may assist. If it still doesn’t move, you may need to use a handle puller, a unique tool developed for this purpose.

Take Apart the Stem Assembly:

The escutcheon is now out of the way, and you can get to the stem assembly. It is the area where the leak must be repaired. To remove the stem assembly, use an adjustable wrench. Examine the washing machine. The most common and usual cause of leaking faucets is that the washer needs to be replaced. The first thing you should do while removing the stem assembly has inspected the washer at the end.

If it has to be replaced, it should be clear that an old washer would have hardened and distorted, which allows the water to flow through.

Replace Your Tub Faucet’s Washer:

Bathtub faucet washers are often constructed of plastic or rubber. Contact with water can cause the washers to dry out and break over time, making a tight seal impossible to achieve. Leaks occur as a result of this. You may, of course, tighten the faucet to halt the leak in the near term, but this would increase the pressure on the old washer, causing it to wear out even faster. Replacement of the washer is the only long-term remedy to this problem.

If the washer is to blame, it must be replaced. Replace the old washer with a new and durable one if you have any on hand. It’s a simple job: unscrew the washer screw, remove the washer, replace it, and reinstall the screw.

If you don’t have one, you’ll have to go to the hardware shop and get one. It’s a good idea to bring the previous one with you if you do this to show the store employees. They will be able to locate the one you require in this manner.

Remove The Handles From the Tub Faucets:

You must first remove the handles from your tub faucet before replacing the washers. Begin by prying out the handle inserts with a pocket knife. The handles have these coatings on them. They’re usually made of plastic and feature “hot” and “cold” markings on them.

Each handle will have a screw once the inserts have been removed. Using a screwdriver, remove the screws. You’ll be able to separate the handles from the stems after the screws are removed. Because rust can cause the handles and stems from staying together, this is often the most challenging stage in the repair.

If you’re having trouble getting them off on your own, consider using a handle puller. Do not attempt to remove the handles by force, as this will severely harm your faucet. Consider calling a professional plumber to assist you if the handle puller isn’t working.

Reassemble And Place Through Its Paces

Secure the handle and put it onto the faucet handles by screwing them into place. Please turn on the water supply and the faucet to test everything out after they’re secure. There should be no leak when you turn the faucet off again.

It’s time to put everything back together once you’ve replaced the washer and examined and replaced the seat as needed. Replace the stem and tighten it with the adjustable wrench, then replace the escutcheon and screw it back into place as necessary, followed by the handle.

You can reinstall the cap that covers it once the handle is secured correctly and screwed back into place. The next and last step is to turn on the water and test the faucet to verify if it is working correctly. You have accomplished the repair work if the water is now running properly and the faucet is no longer leaking.
