5 Easy Steps to Change Your Shower Arm

Shower Arm Replacement

$title$

The shower arm is an important part of your shower, as it is the pipe that connects the showerhead to the water supply. If the shower arm is damaged or leaking, it can cause a number of problems, including low water pressure, uneven water flow, and even flooding. In most cases, it is relatively easy to replace a shower arm yourself, and it only takes a few tools and a little bit of time.

The first step is to turn off the water supply to the shower. Once the water is turned off, you can remove the old shower arm by unscrewing it from the showerhead and the wall. If the shower arm is old or corroded, you may need to use a wrench to loosen it. Once the old shower arm is removed, you can install the new shower arm by screwing it into the showerhead and the wall. Be sure to tighten the shower arm securely, but do not overtighten it, as this could damage the shower arm or the wall.

Once the new shower arm is installed, you can turn on the water supply and check for leaks. If there are any leaks, you can tighten the shower arm further. You may also need to adjust the position of the shower arm to ensure that the water flows evenly from the showerhead. Once the shower arm is installed and leak-free, you can enjoy your new shower.

Gather Necessary Tools and Materials

To begin, gather the necessary tools and materials for changing the shower arm. Essential tools include a pair of adjustable pliers, a pipe wrench or crescent wrench, and a towel or cloth to protect your work surface.

Materials needed for the shower arm replacement include a new shower arm, Teflon tape, and plumber’s putty. The table below provides a comprehensive list of tools and materials:

Tools	Materials
– Adjustable pliers	– New shower arm
– Pipe wrench or crescent wrench	– Teflon tape
– Towel or cloth	– Plumber’s putty

Before starting the replacement process, it’s important to turn off the water supply to the shower. This can be done by closing the main water valve or locating the shut-off valves behind the shower head. Once the water supply is turned off, cover the drain with a towel or cloth to prevent small parts from falling into it.

Turn Off Water Supply

Before you begin working on your shower arm, it’s crucial to disconnect the water supply to prevent any unwanted flooding or water damage. Follow these steps to ensure a safe work environment:

Locate the water shut-off valves:

Typically, water shut-off valves are situated under the sink or behind the toilet in your bathroom. There may be separate valves for hot and cold water, so make sure to close both.

Turn the valves clockwise:

Using a wrench or pliers, turn the water shut-off valves clockwise until they are completely closed. This will block the water flow to your shower.

Test the water supply:

To confirm that the water supply is disconnected, turn on the shower faucet. If no water flows, you have effectively shut off the water supply. If water still comes out, double-check the valves and ensure they are fully closed.

Remove Existing Shower Arm

To remove the existing shower arm, follow these steps:

Turn off the water supply. Locate the shut-off valves for your shower and turn them off. This will prevent water from flowing out when you remove the shower arm.
Cover the drain. Place a towel or drain cover over the drain to prevent any small parts from falling down it.
Wrap a cloth around the base of the shower arm. This will help protect the finish of your shower arm from scratches and dings as you remove it. Alternatively, you can use a strap wrench to provide extra grip without damaging the finish.

Place a wrench on the hexagonal nut behind the shower arm. This nut holds the shower arm in place. Twist the wrench counterclockwise to loosen the nut. If the nut is very tight, you may need to use a pipe wrench for extra leverage.

Once the nut is loose, unscrew the shower arm by hand and pull it straight out of the wall.

Clean Shower Arm Connection

Before removing the old shower arm, clean any dirt or mineral deposits from the connection point. This will make it easier to remove the old arm and install the new one.

Materials You’ll Need

Item
Rags or old towels
Soft scrub brush or toothbrush
White vinegar
Baking soda
Pipe wrench

Steps

Turn off the water supply to the shower.
Remove the showerhead from the shower arm.
Wrap a rag or old towel around the base of the shower arm and use a soft scrub brush or toothbrush to clean away any dirt or mineral deposits.
If the mineral deposits are particularly stubborn, you can soak the connection point in a solution of equal parts white vinegar and water for 30 minutes. Then, use a soft scrub brush or toothbrush to remove the loosened deposits.
Once the connection point is clean, rinse it thoroughly with water and dry it with a clean rag or towel.

Apply Plumber’s Tape

Plumber’s tape, also known as Teflon tape, is a thin, flexible tape used to seal threaded connections in plumbing systems. When wrapped around the threads of a pipe or fitting, it creates a watertight seal that prevents leaks.

To apply plumber’s tape correctly, follow these steps:

Clean the threads: Use a clean cloth or brush to remove any dirt or debris from the threads of the pipe or fitting.
Start wrapping: Hold the end of the tape against the first few threads of the male fitting and begin wrapping it clockwise around the threads.
Overlap the layers: As you wrap the tape, overlap each layer by about one-half of its width. This will create a thicker seal and prevent leaks.
Wrap consistently: Keep the tension on the tape as you wrap it, ensuring that the layers are tight and even.
Finish wrapping: Continue wrapping until you have covered the entire length of the threads and the last few layers extend beyond the end of the fitting.

Number of Layers	Pipe Size
2-3 layers	1/2-inch to 1-inch
4-5 layers	1-1/4-inch to 2-inch
6-7 layers	2-1/2-inch to 4-inch

Install New Shower Arm

Installing a new shower arm is not a daunting task that requires special tools. You can complete this project within an hour or less. The process involves a series of steps, and following them carefully will ensure a leak-free shower arm.

1. Safety First

Before you start, make sure to shut off the water supply valve to prevent any unwanted water flow. It’s also a good idea to wear gloves to protect your hands and a towel nearby to wipe any water spills.

2. Remove the Old Shower Arm

Using an adjustable wrench, loosen the nut that connects the shower arm to the pipe on the wall. Once the nut is loose, carefully remove the shower arm by unscrewing it counterclockwise.

3. Clean the Threads

With the old shower arm removed, check the threads on the pipe and the new shower arm for any corrosion or debris. Use a wire brush or a pipe cleaner to remove any rust or dirt. This will ensure a tight seal for the new shower arm.

4. Apply Plumber’s Tape

Wrap plumber’s tape clockwise around the threads of the pipe on the wall, starting from the bottom. This will help create a watertight seal between the shower arm and the pipe.

5. Install the New Shower Arm

Apply a small amount of pipe dope or sealant to the threads of the new shower arm. Screw the shower arm onto the pipe clockwise by hand until it’s snug. Then, use an adjustable wrench to tighten it further.

6. Secure the Escutcheon

Depending on the type of shower arm you installed, it may come with an escutcheon that covers the base of the shower arm and conceals any gaps. Place the escutcheon over the base and secure it in place using the provided screws or clips.
