Here’s What’s Causing Your Leaky Shower Faucet (and How to Fix It)






Do you have an annoying and persistent dripping shower faucet that leaks continuously? It could be a sign that some part of it needs to be fixed. If left unaddressed, it can lead to bigger problems. Instead of ignoring it, let’s fix it. The first step in performing a repair is to understand why your shower faucet is leaking in the first place. There are five common reasons why your shower faucet can leak, including a worn washer (often the biggest culprit), deteriorated drain valves, mineral buildup, broken or loose faucet components, and excessive water pressure stressing the faucet. Don’t worry – many of these problems are quite easy to fix, and you can probably do them yourself.

While a simple drip may seem like a minor inconvenience that disrupts your peaceful shower time, it could be a sign of a more serious problem. Not only that, but ignoring a leaking shower faucet can lead to increased water bills. Yep, that small water leak may seem like no big dealbut it can waste a significant amount of water and result in higher utility costs. Continuous leaks can also cause water damage to your bathroom walls, floors and fixtures, leading to potential mold growth and structural problems. Taking the time to understand and address the cause of your leaking shower faucet can help you maintain a functional and efficient plumbing system, ensuring your shower remains in good working order.

Worn tray

One of the most common causes of a leaking shower faucet is a worn out washing machine. The washer is a small circular component placed inside the faucet that helps create a watertight seal when the faucet is turned off. Over time, the flow of water and high pressure can cause the washing machine to deteriorate, which inevitably leads to leaks. This problem can cause a constant drip that eventually results in a spike in your water bill. In addition, the constant drip can cause water damage to your bathroom fixtures and promote the growth of mold and mildew, which can be harmful to your health. You want to immediately replace the washer in your faucet to avoid all of these problems and prevent them from escalating.

Fortunately, fixing a tile is a fairly simple task that you can most likely handle yourself with a few basic tools. For starters, you’ll want to turn off the water supply to the shower to prevent water flow while you work. Then you usually have to remove the faucet handle to access the tray. Depending on the type of faucet, unscrew the handle and remove any decorative caps or caps. Once you have access to the tray, you can remove the old one and put the new one in its place. Washers are inexpensive and you can find them at most hardware stores or online. It’s a good idea to take the old tray with you to the store to ensure you get the right size and type.

Diverter valve

Another common cause of a leaking shower faucet is a deteriorated drain valve. The diverter valve is a crucial component that controls the flow of water between the tub and the shower head. The diverter valve can wear out due to constant use and exposure to water, leading to a leaky shower faucet. When this valve deteriorates, it can fail to seal properly, causing water to leak from the tub spout even when the shower is in use. This is problematic because it not only wastes water, but reduces the water pressure in your shower, making it less efficient.

With a little patience and some basic tools, you can fix the diverter valve yourself. You can buy diverter valves at most hardware stores or online. Just make sure you get one that’s the right size and type for your specific faucet model. To replace the drain valve, you should turn off the water supply to the shower and then cover the drain so that no screws accidentally slide down it. Next, remove the faucet handle and cover plate to access the diverter valve. This usually involves simply unscrewing the handle and plate. When you remove the diverter valve you should be able to see corrosion and deterioration of the valve. Go ahead and replace it with the new one and put everything back in place. This new valve will last about five years on average, but it can work well for longer if you maintain it.

Mineral build-up

Mineral buildup is another common cause of a leaking shower faucet. Hard water, which contains high levels of minerals such as calcium and magnesium, can leave deposits inside the faucet. These ugly mineral deposits can collect on the internal components, preventing the faucet from sealing properly and causing it to leak. Hard water buildup can also reduce water flow, causing your shower to have less water pressure. Addressing the mineral build-up in your shower faucet will help maintain your plumbing system and the life of your faucet.

Fortunately, you can tackle this problem with a few common household items and a little elbow grease. You will want to shut off the water supply to the shower to avoid further leakage while you work. Remove the faucet handle and any other parts that need cleaning. You can then soak these components in a mixture of white vinegar, baking soda and water, which can dissolve the mineral build-up. If these parts do not come off easily, you can also wrap them in a plastic bag filled with the solution. You’ll need the elbow grease when using a brush or cloth to scrub away any stubborn deposits. If there is more serious build-up that does not lift with this method, you may need to invest in a specialized cleaner. After cleaning the parts thoroughly, rinse them thoroughly and reassemble the faucet. Turn the water supply back on and check for any remaining leaks. This simple cleaning will help conserve water and keep your bathroom sparkling clean.

Broken or loose faucet components

Another reason why your shower faucet is leaking could be due to loose or broken components in the faucet itself. The internal parts of the faucet, such as screws, washers and seals, can loosen or break due to regular wear and tear. When these components are not working properly, they can cause water to leak out of the faucet. This can become an incessant problem as it not only leads to water wastage but can also result in inconsistent water pressure and temperature control. Loose or broken parts can also make the faucet difficult to operate, leading to additional wear and potential damage to other components. If ignored, these problems can become more serious and cause more significant problems that may require replacement of the entire faucet.

Fixing broken or loose components in your shower faucet is something you can probably do yourself. Turn off the water supply to the shower, then remove the faucet handle and any other parts necessary to reach the internal components. You will probably need to unscrew the handle and remove any caps or caps. When you can access the internal parts, inspect them for signs of wear, damage or looseness. Tighten any loose screws or nuts and replace any broken washers or seals. Most of these parts should be fairly cheap to buy and easy to find at a nearby hardware store.

High water pressure

High water pressure can be a significant cause of leaks in your plumbing, including your shower faucet. While it may feel luxurious to have a powerful stream of water, excessive water pressure can stress your plumbing system. When water pressure exceeds recommended levels (usually between 40 and 80 psi), it can cause various problems. The constant high pressure can wear down normal faucet components, such as seals and washers, much faster than normal. This not only leads to leaks, but can lead to pipes bursting, leading to potentially serious water damage in your home. It can also increase your water bills as more water is forced through the system than necessary.

One of the first steps you can take to deal with high pressure is to measure the water pressure with a gauge. You can attach the meter to any faucet to get a reading. If the pressure is above 80 psi, you need to do it replace your water pressure regulator. This valve reduces the water pressure entering your home to a safer level. The gauges and regulators are usually available at your local hardware store and are relatively easy to install. Be sure to follow the manufacturer’s instructions when installing your regulator and install it at the main water line entering your home. If you are not comfortable doing this yourself, you can always hire a professional plumber to do it correctly.
