How To Replace Shower Arm

Shower arms are an essential part of any shower system, and they can start to leak or become damaged over time. Replacing a shower arm is a relatively simple task that can be completed in a few hours. In this article, we will provide you with step-by-step instructions on how to replace a shower arm, as well as some tips to help you get the job done right. However, if you are not comfortable working with plumbing, it is always best to call a professional plumber.

Before you begin, you will need to gather a few tools and materials. These include a new shower arm, a wrench, a screwdriver, and some Teflon tape. Once you have all of your tools and materials, you can follow these steps to replace the shower arm:

1. Turn off the water supply to the shower. This is typically done by turning off the main water valve for the house.
2. Remove the old shower arm. Use a wrench to loosen the nut that is holding the shower arm in place. Once the nut is loose, you can unscrew the shower arm by hand.
3. Apply Teflon tape to the threads of the new shower arm. This will help to create a watertight seal and prevent leaks.

Selecting the Right Shower Arm

Choosing the right shower arm is essential for a seamless showering experience. Consider the following factors when making your selection:

Finish and Material:

The finish of the shower arm should complement your bathroom decor. Common finishes include chrome, brushed nickel, and oil-rubbed bronze. The material, such as brass or stainless steel, affects durability and corrosion resistance.

Length and Reach:

The length of the shower arm determines the distance the showerhead extends from the wall. A shorter arm provides a closer, more intimate spray, while a longer arm allows for a wider coverage. Choose a length that aligns with the size of your shower enclosure and your personal preference.

Connection Type:

Shower arms can have different connection types, including threaded, slip-fit, and universal. Ensure that the arm’s connection type matches the existing plumbing fixtures and showerhead.

Flow Rate:

If you have a high-flow showerhead, choose a shower arm with a higher flow rate to prevent water pressure from dropping.

Specific Features:

Some shower arms offer additional features, such as an adjustable angle or a built-in diverter valve. Consider your specific needs and preferences when choosing an arm with these features.

Removing the Old Shower Arm

Replacing a shower arm is a relatively straightforward task that can be completed in a few simple steps. Before you begin, gather the necessary tools: a wrench, pliers, and a new shower arm. It is also helpful to have a bucket or towel on hand to catch any water that may leak out during the process.

Step 1: Turn off the water supply

The first step is to turn off the water supply to the shower. This is typically done by locating the main water shut-off valve for your home and turning it to the “off” position. If you are unable to find the main water shut-off valve, you can turn off the water supply to the shower by closing the individual shut-off valves located under the sink or behind the toilet.

Step 2: Remove the old shower arm

Once the water supply is turned off, you can begin removing the old shower arm. To do this, first use a wrench to loosen the nut that connects the shower arm to the showerhead. Once the nut is loose, you can use your hands to unscrew the showerhead from the shower arm. Once the showerhead is removed, you can use a pair of pliers to grip the base of the shower arm and unscrew it from the wall. Be careful not to overtighten the pliers, as this could damage the shower arm.

Preparing the Shower Pipe

Before removing the old shower arm, you need to prepare the shower pipe. This involves shutting off the water supply, draining the water from the pipe, and removing any old sealant or debris.

Shutting Off the Water Supply

The first step is to shut off the water supply to the shower. This is usually done by turning off the main water valve, which is typically located near the water meter. If you can’t find the main water valve, you can turn off the water supply to the shower by turning off the valves under the sink in the bathroom.

Draining the Water from the Pipe

Once the water supply is turned off, you need to drain the water from the shower pipe. This can be done by opening the shower head and letting the water flow out. You can also use a wet/dry vacuum to suck the water out of the pipe.

Removing Old Sealant or Debris

Once the water is drained from the pipe, you need to remove any old sealant or debris that may be blocking the shower arm. This can be done using a putty knife or a wire brush. Be careful not to damage the pipe when removing the old sealant or debris.

Tools and Materials
Adjustable wrench or pliers
Putty knife or wire brush
Wet/dry vacuum (optional)

Applying 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 applied correctly, it helps prevent leaks and ensures a watertight seal.

Step 4: Wrapping the Threads

To wrap the threads correctly, follow these steps:

**Determine the Direction of Threads:** Shower arms typically have right-hand threads, meaning you turn them clockwise to tighten them. Wrap the tape in the same direction as the threads.
**Start at the End:** Begin wrapping the tape at the end of the threads, leaving about 1/2 inch exposed.
**Overlap the Layers:** Overlap each layer of tape by about half. Wrap the tape tightly but avoid overtightening, as this can damage the threads.
**Use a Generous Amount:** Apply enough tape to cover the threads completely. As a general rule of thumb, make 5-7 tight wraps.
**Finish by Tucking the Last Layer:** To finish, tuck the last layer of tape under the first layer to secure it. This prevents the tape from unraveling when the shower arm is tightened.

Tip

If you’re not sure if you’ve applied enough tape, try the “water test.” Turn on the water and check for any leaks. If there are no leaks, you’ve successfully sealed the connection.

Installing the New Shower Arm

5. Apply Plumber’s Putty and Install the Arm

As the final step of installing the new shower arm, you need to apply plumber’s putty to the threads of the arm. Use your hands to roll out a rope of putty about 1/2 inch in diameter, then shape it into a cone.

Place the cone of putty over the threads of the shower arm, pressing it firmly into place. Smooth out the excess putty with your fingers or a putty knife, making sure that it completely covers the threads and extends about 1/4 inch onto the shower pipe.

Carefully screw the shower arm onto the shower pipe, hand-tightening it as much as possible. Avoid overtightening, as this can damage the threads or the shower arm.

Use a wrench or pliers to further tighten the shower arm. Turn the arm clockwise until it is snug, but be careful not to overtighten.

Attaching the Shower Head

Once the shower arm is installed, it’s time to attach the shower head. Here’s how to do it:

Apply Teflon Tape: Wrap Teflon tape clockwise around the male threads of the shower arm, starting about 2 inches from the end. Wrap it tightly and evenly for about 6-8 turns.
Screw on the Shower Head: Hand-tighten the shower head clockwise onto the shower arm. Ensure that it is straight and facing the desired direction.
Use a Wrench: Use a wrench to tighten the shower head further. Do not overtighten, as this can damage the threads or the shower head itself.
Check for Leaks: Turn on the water supply and check for leaks at the connection between the shower head and shower arm. If any leaks occur, tighten the connection further using the wrench.

Tips for Attaching the Shower Head

Here are some additional tips for attaching the shower head:

Use a new shower head washer if necessary.
Tighten the connection securely, but avoid overtightening.
If the shower head is angled, adjust it to the desired position before tightening.
Wrap Teflon tape in the direction of tightening to prevent leaks.

Sealing the Joints

After installing the new shower arm, it’s crucial to properly seal the joints to prevent leaks. Here’s a detailed step-by-step guide:

1. Clean the Surfaces:

Thoroughly clean the area around the joints with rubbing alcohol or a degreasing cleaner to remove any dirt, debris, or old caulk.

2. Dry the Surfaces:

Allow the cleaned surfaces to dry completely before applying the sealant.

3. Choose the Right Sealant:

Use a high-quality silicone sealant specifically designed for bathroom applications. It should be mold-resistant and have good adhesion to both metal and the shower wall.

4. Apply the Sealant:

Cut the tip of the sealant tube at a 45-degree angle and apply a bead of sealant around the base of the shower arm, where it meets the wall.

5. Smooth the Sealant:

Use a wet finger or a small tool to smooth the sealant bead and remove any excess.

6. Allow the Sealant to Cure:

Refer to the manufacturer’s instructions for the recommended curing time. Typically, silicone sealants take 24-48 hours to fully cure.

7. Test for Leaks:

After the sealant has cured, turn on the shower and observe whether any water is leaking. If there are leaks, apply additional sealant and allow it to cure again.

Table: Troubleshooting Common Joint Sealing Problems

Problem	Solution
Sealing not adhering properly	Clean surfaces thoroughly, dry completely, and use the right sealant
Leaks after curing	Check for gaps or incomplete sealing, remove the old sealant, and re-apply
Mold growth	Use a mold-resistant sealant, keep the area dry, and clean regularly
