What You'll Learn

Tools needed for removal
Removing an old copper shower drain requires a precise set of tools to avoid damaging surrounding tiles or plumbing. The first essential tool is a tubing cutter, specifically one with a compact design to navigate tight spaces. Copper is relatively soft, but precision is key to ensure a clean cut without burrs. Pair this with a deburring tool to smooth the edges of the cut pipe, preventing injuries and ensuring a snug fit for the replacement drain. These tools are not just practical—they’re indispensable for a professional finish.
While cutting the drain pipe is crucial, loosening the drain itself demands different tools. A basin wrench is ideal for reaching the nuts securing the drain to the shower base. Its long handle and pivoting jaw allow access in cramped areas, where standard wrenches fail. For stubborn corrosion or over-tightened fittings, a penetrating oil like WD-40 should be applied 15–20 minutes before attempting removal. This combination of mechanical leverage and chemical assistance minimizes the risk of breaking the drain or surrounding fixtures.
In some cases, the drain may be soldered to the pipe, requiring a propane torch and flux to melt the joint. This method is more invasive and should only be used if other options fail. Heat the solder joint evenly, avoiding prolonged exposure to prevent tile damage. A heat shield or damp cloth can protect adjacent surfaces. Once the solder melts, use pliers to gently separate the drain. This approach is advanced and carries risks, so proceed with caution or consult a professional if unsure.
Finally, no removal toolkit is complete without safety gear. Copper pipes may have sharp edges, and soldering involves open flames. Wear cut-resistant gloves to protect hands, and safety goggles to shield eyes from debris or sparks. A fire extinguisher should be nearby when using a torch. These precautions transform a potentially hazardous task into a manageable DIY project, ensuring both efficiency and personal safety.

Steps to loosen stuck drain
Removing an old copper shower drain can be a daunting task, especially when it’s stuck due to years of corrosion, mineral buildup, or improper installation. The key to success lies in methodical loosening, avoiding brute force that could damage surrounding tiles or plumbing. Begin by assessing the drain’s condition: look for visible corrosion, cracks, or signs of adhesive like plumber’s putty. If the drain is soldered to the pipe, you’ll need to address the solder joint before attempting removal. Always wear safety gear, including gloves and eye protection, as rusted edges and debris can pose risks.
Step 1: Apply a penetrating oil or lubricant to weaken the bond between the drain and the pipe. Products like WD-40, PB Blaster, or a specialized pipe thread lubricant work well. Spray or brush the oil generously around the drain’s base and let it sit for at least 30 minutes—overnight for severely stuck drains. This step is crucial for breaking down rust and mineral deposits that act as adhesives. For added effectiveness, cover the area with plastic wrap to prevent evaporation and allow deeper penetration.
Step 2: Use heat to expand the metal and loosen the drain. A propane torch or heat gun can be applied carefully to the drain’s edges, warming the copper to expand it slightly. Be cautious not to overheat, as excessive heat can damage surrounding materials or warp the drain. Heat for 10–15 seconds, then attempt to turn the drain counterclockwise with a wrench or drain key. Repeat the heating process if necessary, but always prioritize safety to avoid burns or fires.
Step 3: Employ mechanical tools to gain leverage. A drain removal tool or large flathead screwdriver can be inserted into the drain’s screw slots (if present) to pry it loose. For drains without screws, use a reciprocating saw with a metal-cutting blade to carefully cut through the drain flange, ensuring not to damage the pipe below. Alternatively, a drain extractor tool, which grips the drain’s edges, can be twisted counterclockwise to break the seal.
Cautionary Notes: Avoid using excessive force with tools, as this can crack tiles or damage the pipe. If the drain is soldered, you’ll need to melt the solder joint first using a propane torch, then proceed with removal. Always have a bucket and towels ready to catch any water that may spill from the pipe once the drain is loosened.

Handling corroded copper parts
Corroded copper parts in an old shower drain can turn a simple removal task into a frustrating ordeal. Copper, while durable, is susceptible to corrosion over time, especially in damp environments. This corrosion often manifests as green or black deposits, making the metal brittle and difficult to work with. Understanding the nature of this corrosion is the first step in effectively handling and removing these parts.
To tackle corroded copper, start by assessing the extent of the damage. Minor corrosion can often be managed with household items like vinegar or lemon juice, which are mild acids that can dissolve copper oxide. For more severe cases, commercial descaling agents or a mixture of baking soda and hydrogen peroxide can be applied. Allow the solution to sit for 15–30 minutes, then scrub gently with a soft-bristled brush to avoid further damage to the copper. Rinse thoroughly with water afterward to prevent residual chemicals from accelerating future corrosion.
When physical removal is necessary, corroded copper parts may require cutting or disassembly. Use a hacksaw or reciprocating saw with a metal-cutting blade, but proceed cautiously to avoid damaging surrounding fixtures. For threaded connections, penetrating oil like WD-40 can be applied to loosen the grip of corrosion. Allow the oil to penetrate for at least 10 minutes before attempting to unscrew the part. If the part remains stubborn, applying heat with a propane torch can expand the metal, but this should be done sparingly to prevent warping or melting nearby materials.
Preventing future corrosion is as important as addressing the current issue. Once the old drain is removed, clean the area thoroughly and consider applying a corrosion inhibitor or protective coating to new copper parts. Regular maintenance, such as periodic cleaning and inspection, can extend the lifespan of copper fixtures. For those in humid climates, installing a dehumidifier in the bathroom can reduce moisture levels, slowing the corrosion process.
In summary, handling corroded copper parts requires a combination of chemical treatment, careful mechanical intervention, and preventive measures. By understanding the causes and effects of corrosion, homeowners can effectively remove old copper shower drains and ensure the longevity of their replacements. Patience and the right tools are key to navigating this common plumbing challenge.

Replacing with new drain assembly
After removing the old copper shower drain, the next critical step is installing a new drain assembly to restore functionality and prevent leaks. This process requires precision and attention to detail to ensure a watertight seal and long-term durability. Begin by selecting a replacement drain assembly compatible with your shower’s dimensions and plumbing setup. Most modern assemblies are made of PVC or ABS plastic, which resist corrosion and are easier to install than copper. Ensure the new drain includes a strainer, gasket, and threaded adapter for secure attachment to the drainpipe.
The installation starts with cleaning the drain opening thoroughly to remove debris, old caulk, or residue. Apply a bead of plumber’s putty or silicone sealant around the underside of the new drain’s flange to create a watertight barrier between the drain and the shower pan. Insert the drain assembly into the opening, pressing firmly to ensure the sealant adheres evenly. From below, tighten the locking nut onto the drainpipe threads, using adjustable pliers or a wrench. Be cautious not to overtighten, as this can crack the shower pan or damage the assembly.
Once the drain is secured, attach the strainer to the top of the assembly by screwing it into place. Test the seal by running water through the drain and checking for leaks beneath the shower. If leaks occur, loosen the locking nut slightly, reposition the gasket, and retighten. For added protection, apply a thin layer of silicone caulk around the top edge of the drain flange to prevent water seepage into the subfloor. Allow the caulk to cure for at least 24 hours before using the shower.
Comparing this process to the removal of the old copper drain highlights the simplicity of modern materials. Copper drains often require cutting, soldering, or specialized tools, whereas PVC or ABS assemblies are designed for straightforward installation. This shift in materials not only reduces labor but also minimizes the risk of future corrosion or leaks. By following these steps, homeowners can confidently replace an old copper drain with a new assembly, ensuring a reliable and efficient shower drainage system.
