What You'll Learn
Shutting off water supply
Before attempting any plumbing work, including rerouting pipes for a shower head, the first critical step is to shut off the water supply. Failure to do so can result in flooding, water damage, and an unnecessary mess. Most homes have a main shut-off valve located near the water meter or where the main water line enters the house. This valve controls the flow of water to the entire property. Turning it clockwise will stop the water supply, ensuring a dry and safe work environment. If you’re unsure where this valve is, consult your home’s blueprints or contact a professional plumber for guidance.
In some cases, shutting off the main water supply may not be necessary if your plumbing system includes individual shut-off valves for specific fixtures. For shower head rerouting, look for a valve near the shower or in the bathroom’s access panel. These valves are typically located under the sink or behind the shower wall. Turn the valve clockwise to shut off the water flow to the shower only, allowing you to work on the plumbing without affecting the rest of the house. If such a valve is absent, you’ll need to rely on the main shut-off valve.
Shutting off the water supply isn’t just about turning a valve; it’s also about verifying that the water flow has stopped completely. After closing the valve, open the shower faucet to release any residual water in the pipes. This step is crucial to avoid unexpected leaks or spills during the rerouting process. Additionally, check for drips or trickles, as these could indicate a faulty valve or incomplete closure. If water continues to flow, double-check the valve or consider using the main shut-off as a backup.
For those working on older plumbing systems, caution is especially important. Aging pipes and valves may be corroded or difficult to operate, increasing the risk of breakage. Apply steady, even pressure when turning valves, and avoid using excessive force. If a valve is stuck or resistant, apply a lubricant like WD-40 or penetrate oil and allow it to sit for 10–15 minutes before attempting again. If the valve still won’t budge, consult a professional to avoid damaging the plumbing system further.
Finally, shutting off the water supply is not just a preparatory step—it’s a safety measure that protects both your home and your project. By ensuring the water is off, you minimize the risk of accidents and create a controlled environment for rerouting the shower head plumbing. Always take the time to locate and test the appropriate shut-off valves before beginning any work. This small but essential task can save you from costly repairs and unnecessary stress, making it a cornerstone of successful DIY plumbing projects.

Removing old shower head
Before tackling the rerouting of plumbing for a shower head, the first step is removing the old fixture. This process, while seemingly straightforward, requires attention to detail to avoid damage to pipes or fixtures. Start by turning off the water supply to the shower to prevent any accidental spills or pressure issues. Locate the shut-off valve, typically found in the bathroom or a nearby utility closet, and turn it clockwise until it’s fully closed. If there’s no dedicated valve, you may need to shut off the main water supply to the house.
Once the water is off, inspect the shower head for any visible signs of wear, corrosion, or mineral buildup. These factors can affect how easily the head is removed. Use a clean cloth to grip the shower head firmly, as this provides better traction than bare hands. If the head is stuck due to mineral deposits or old plumbing tape, apply penetrating oil (like WD-40) around the connection point and let it sit for 10–15 minutes. This loosens the threads and reduces the risk of stripping the fitting.
With the shower head prepared, use an adjustable wrench or pliers to grip the nut connecting the head to the pipe. Wrap the jaws of the tool with a cloth or tape to protect the finish. Turn the nut counterclockwise, applying steady pressure. If resistance is met, avoid forcing it, as this can damage the pipe. Instead, tap the handle of the wrench gently with a mallet to break the seal. For stubborn cases, consider using a strap wrench, which provides more leverage without marring surfaces.
After the old shower head is removed, inspect the pipe threads for damage, rust, or debris. Clean the threads with a wire brush and steel wool to ensure a secure fit for the new fixture. Wrap the threads with new Teflon tape (3–5 layers) in a clockwise direction, or apply pipe dope for a more permanent seal. This step is crucial for preventing leaks and ensuring longevity. Finally, test the connection by turning the water supply back on briefly before proceeding with rerouting or installing a new shower head.

Measuring and cutting pipes
Accurate measurements are the cornerstone of successful pipe rerouting. Begin by determining the distance from the existing water supply lines to the desired shower head location. Use a tape measure to account for any bends or angles, adding extra length to accommodate joints and fittings. Mark the measurements directly onto the pipe with a permanent marker or masking tape to ensure clarity during the cutting process.
Cutting pipes requires precision and the right tools. For copper or PVC pipes, a tubing cutter is ideal. Position the cutter around the pipe at the marked measurement, tighten the cutter’s wheel against the pipe, and rotate it around the circumference while applying gentle pressure. Repeat this process until the pipe is cleanly severed. For thicker or metal pipes, a hacksaw or reciprocating saw with a metal-cutting blade may be necessary. Always wear safety goggles and gloves to protect against sharp edges and debris.
After cutting, inspect the pipe ends for burrs or rough edges, which can disrupt water flow or damage seals. Use a deburring tool or fine-grit sandpaper to smooth the edges. For PVC pipes, a deburring tool is often included with the cutter. For copper pipes, a reamer tool can also be used to ensure a clean, rounded edge. Properly prepared ends will ensure secure connections and prevent leaks.
A common mistake is misjudging the length needed for fittings. Always account for the depth of couplings, elbows, or tees when measuring. Dry-fit the pieces before final installation to confirm alignment and length. If adjustments are needed, mark the pipe again and re-cut. This trial assembly saves time and reduces the risk of errors during the actual plumbing work.
Finally, consider the type of pipe and its compatibility with your shower system. Copper pipes require soldering or compression fittings, while PVC pipes use solvent cement or threaded connections. Ensure the pipe material and size match the existing plumbing and local building codes. Taking these steps ensures a professional-grade reroute that functions reliably for years to come.

Installing new plumbing lines
Rerouting plumbing for a shower head often requires installing new lines, especially if you're relocating the fixture or upgrading to a multi-function system. This process involves careful planning, precise execution, and adherence to local building codes. Begin by assessing the existing plumbing layout to determine the most efficient route for the new lines. Consider factors like wall cavities, floor joists, and proximity to the water supply and drain. Use a stud finder to locate structural elements and avoid unnecessary damage during installation.
Steps for Installation:
- Plan the Route: Measure the distance from the water supply source (typically near the shower valve) to the new shower head location. Choose the shortest path possible to minimize material costs and reduce pressure loss.
- Gather Materials: Purchase copper, PEX, or CPVC pipes based on your preference and local regulations. Ensure you have fittings, valves, and a pipe cutter or tubing cutter. For PEX, a crimping tool or expansion system is essential.
- Cut and Assemble Pipes: Measure and cut pipes to length, leaving extra material for connections. Assemble fittings and secure joints using soldering (for copper), crimping (for PEX), or solvent cement (for CPVC). Test connections for leaks before finalizing installation.
- Install the Lines: Run the pipes through walls or floors, securing them with straps or clips every 18–24 inches. Ensure proper slope for drain lines if applicable. Use access panels for concealed areas to allow future maintenance.
Cautions: Avoid bending pipes excessively, as this can restrict water flow. Always shut off the main water supply before cutting into existing lines. If drilling through walls, use a right-angle drill attachment to prevent damage to surrounding structures. For multi-story homes, account for increased pressure by using thicker pipes or adding pressure regulators.
Practical Tips: Label new lines with their function (hot, cold, drain) for future reference. Insulate pipes in unheated areas to prevent freezing. If working with PEX, avoid sharp bends by using PEX coils or flexible connectors. For copper pipes, apply flux evenly to ensure strong solder joints.

Testing for leaks
After rerouting your shower plumbing, the integrity of your work hinges on meticulous leak testing. Even a pinhole leak can lead to mold, water damage, and structural issues over time. Before turning on the water supply, inspect all connections for tightness, ensuring threads are aligned and joints are securely sealed with Teflon tape or pipe dope. Use a torque wrench to tighten fittings to manufacturer specifications—overtightening can warp components, while undertightening invites leaks.
Once connections are secure, pressurize the system slowly to avoid stress fractures. Start by opening the supply valve incrementally, allowing water to fill the lines gradually. Listen for hissing sounds, which often indicate escaping air or water under pressure. Visually inspect joints for moisture, using a flashlight to illuminate hard-to-see areas. For a more precise test, wrap dry paper towels or toilet paper around each connection and observe for dampness over 15–20 minutes.
For a comprehensive assessment, perform a pressure test using a gauge attached to the supply line. Isolate the shower plumbing from the rest of the system and pressurize it to 80–100 psi, holding this pressure for 10–15 minutes. Monitor the gauge for drops, which signal leaks. If the pressure holds, release it slowly and inspect again for moisture. This method is particularly critical for copper or PEX systems, where leaks may not manifest immediately.
In multi-story homes, test the shower plumbing both with and without fixtures running elsewhere in the house. Pressure fluctuations from simultaneous usage can expose weak points. Run faucets or flush toilets while observing the shower connections for signs of weeping or dripping. Address any issues before finalizing the installation, as repairing leaks post-wall closure is costly and disruptive.
Finally, consider using leak detection solutions for hidden systems. Add a few drops of food coloring or specialized dye to the water supply and observe for color seepage at joints. This method is especially useful for concealed pipes or tight spaces where visual inspection is challenging. By combining these testing strategies, you ensure your rerouted shower plumbing is not just functional but also leak-free, safeguarding your home for years to come.
