Identifying Why Your Bathtub Faucet Leaks Or Drips
Getting to the root of your leaky bathtub faucet issue is an integral part of the resolution process. While several factors can contribute to this problem, three of the most common culprits include worn-out components, damaged seals, and the buildup of hard water minerals. Let’s delve deeper into each of these.
Every faucet consists of several components, all of which experience wear and tear over time. One such critical component is the diverter valve. This handy little piece of hardware is responsible for redirecting the water flow from the tub faucet up to the showerhead. Over time, the constant water pressure, along with regular wear and tear, can take a toll on the diverter valve, so the leaking bathtub faucet can even break down entirely. When this happens, the water continues to flow through the tub spout, causing a leak even when the shower is running.
Just like any water fixture, your bathtub faucet contains several seals designed to prevent leaks. These seals can be found in various parts of the faucet assembly, such as around the diverter valve and at the base of the faucet where it connects to the pipes. These seals can wear out over time or become damaged due to excessive water pressure or chemical reactions with harsh water elements. When a seal deteriorates or breaks, it allows water to leak out around the faucet or spout, causing the annoying drip you’re trying to stop.
Mineral Deposit Buildup
If your home receives hard water, your plumbing fixtures, including the bathtub faucet, are prone to mineral deposit buildup. Hard water contains high levels of minerals like calcium and magnesium, which can accumulate within your faucet over time. This buildup can obstruct the diverter valve, causing it to function inefficiently and thereby resulting in the annoying leak you’re experiencing. The presence of these minerals can also contribute to the deterioration of the faucet’s components and seals, compounding the problem.
Now that we’ve identified the potential causes of a leaky bathtub faucet, it’s important to note that determining the exact cause in your case may require a bit of investigative work. Observing the nature and extent of the leak, examining the condition of your faucet’s components and seals, and knowing if your water supply is hard or soft can all provide valuable clues.
Types of bathtub faucets
Before you can roll up your sleeves and get down to the business of fixing your leaky bathtub faucet, you need to understand what kind of faucet you’re dealing with. Faucets come in many varieties, but the three most common types you’ll find in homes are ball, cartridge, and compression faucets. Each type has a unique design and operates slightly differently, affecting the steps you’ll take to resolve leaks.
Ball faucets are single-handle faucets that swivel back and forth to control water temperature and up and down to control water flow. The name comes from the ball-shaped component that sits atop the faucet’s base. Inside, there are several parts including seals, springs, and inlet holes, which can wear out or fail over time leading to leaks. Identifying a ball faucet is easy, look for the signature “ball” on its cap.
Cartridge faucets can be single-handle or double-handle, but the telltale sign is the action used to control the water flow and temperature. If your faucet involves a smooth upward-downward motion for water flow control and a left-right motion for temperature control, you have a cartridge faucet. The cartridge inside these faucets can wear out or become blocked with mineral deposits, causing water leaks.
Compression faucets are a bit old-school, but they are still commonly found in many homes. These are typically double-handle faucets, where you turn each handle to open the valve and increase water flow. The more you turn, the higher the water flow. The main parts that can fail in compression faucets are the rubber washers. Over time, these washers can wear out, and water can start to leak around the handle or from the spout.
Identifying your faucet type is crucial to the repair process because different faucet types have different parts that can fail and cause leaks. Knowing what kind of faucet you have will guide you toward what part to look for and how to replace or repair it. Understanding your faucet type can also help you find more specific guidance or video tutorials online, as the process can vary between faucet types.
Tools to replace or fix bathtub faucets
Tackling a leaky bathtub faucet is easier when you’re armed with the right tools. Depending on the severity of the leak and your faucet type, you may need to replace some components. Here’s a checklist of items you should have on hand before you start the repair:
An adjustable wrench is a must-have tool for any plumbing job. You’ll need this to remove the faucet handle and other parts that are typically screwed on tightly.
Philips Head Screwdriver
A screwdriver is usually necessary to remove the handle of the faucet, as well as other parts depending on your specific model. It’s helpful to have both a flat-head and a Phillips-head screwdriver since different faucets may require different types.
Teflon tape, also known as plumber’s tape, is used to ensure a tight seal on threaded pipe connections. This can be crucial in preventing new leaks from developing after you’ve completed your repair.
Plumber’s grease is a handy tool for lubricating parts during reassembly. It can also help to ensure the smooth operation of your faucet and extend the lifespan of its parts.
Replacement Parts for the Faucet
If you’ve identified a specific component of your faucet that is worn out or broken, you’ll need to have a replacement part on hand. This might include seals, cartridges, washers, or even an entirely new faucet if your current one is beyond repair.
CLR or White Vinegar
These are useful for breaking up any mineral deposits that may be causing your faucet to leak. You can submerge your faucet or faucet parts in a solution of these to help clear away the buildup.
Container and Old Toothbrush
These will be necessary if mineral buildup is a problem. You’ll use the container to soak the parts in a CLR or vinegar solution, and the toothbrush to scrub away any stubborn deposits.
Remember, before you start, it’s crucial to shut off the water supply to your bathtub to prevent any water mishaps while you’re working. Once you have your tools gathered, you’re ready to dive into the repair!
How to Fix a Leaky Faucet
Before diving into the repair process, it’s essential to properly prepare your work area and ensure safety.
- Turn off the water supply: Locate the water supply valves for your bathtub. These are usually found behind the wall of the tub or in an access panel in an adjacent room. Turn these valves clockwise to shut off the water supply.
- Protect the work area: To prevent damage to your bathtub, lay down a towel or a non-slip mat where you will be working. This also provides a place to hold the small parts and prevent them from sliding down the drain.
Disassembling the Bathtub Faucet
This process may vary depending on your faucet type (ball, cartridge, or compression). However, the general steps are as follows:
- Remove the handle: The handle is typically held in place by a screw, which may be hidden under a decorative cap. Remove the cap (if present) and unscrew the handle. Gently pull to remove it from the assembly.
- Unscrew the packing nut: With your adjustable wrench, carefully unscrew the packing nut that secures the faucet stem. Be careful not to scratch the finish of your faucet.
- Remove the faucet stem: Depending on your faucet type, the stem may be removed by unscrewing or pulling it out. Make a note of the orientation for reassembly.
Identifying and Replacing Damaged Faucet Components
Inspect the disassembled parts for signs of damage or wear. Pay particular attention to seals and the diverter valve for any mineral deposits.
- Clean or replace damaged parts: If the seals are worn out or the diverter valve is clogged with mineral deposits, you need to clean or replace them. Submerge the faucet parts in a CLR or vinegar solution for about 15 minutes, then scrub away any stubborn deposits with an old toothbrush.
- Purchase replacements: If a part is too worn or damaged, you must replace it. Take the old part to your local home improvement store to find an exact match.
Reassembling the Bathtub Faucet
Once you’ve replaced or cleaned all necessary components, you’re ready to reassemble your faucet.
- Reinstall the stem: Insert the stem back into the faucet body in the same orientation as before.
- Secure with the packing nut: Replace the packing nut and secure it with your adjustable wrench. Be careful not to overtighten it as it could damage the parts.
- Replace the handle: Position the handle back onto the stem and secure it with the screw. If a cap was present, snap or screw it back into place.
- Test the faucet: Turn the water supply back on and test your faucet. Both the tub spout and the showerhead should work without any leaks. If you still notice leaks, you may need to tighten the packing nut slightly more or replace additional parts.
Congratulations! You have successfully repaired your leaky bathtub faucet. The next time you find yourself dealing with a similar issue, you’ll know exactly what to do.
