If you’ve ever tried to remove copper push fit plumbing fittings, you know how frustrating it can be—especially when you’re worried about damaging pipes or causing leaks. Whether you’re upgrading your plumbing system, fixing a faulty joint, or just doing routine maintenance, knowing how to remove copper push fit plumbing fittings safely and efficiently is a must. In this guide, we’ll walk you through a proven, tool-friendly method that preserves your pipes and saves you time (and money!).
What Are Copper Push Fit Fittings?
Copper push fit fittings (also called “push-to-connect” or “push-fit” connectors) are quick-install plumbing components that allow you to join copper pipes without soldering, threading, or glue. They’re popular for DIY repairs and professional installations alike due to their speed and reliability.
Most push fit fittings use a stainless steel grab ring and an O-ring seal that grips the pipe tightly when inserted. While easy to install, removal requires a specific release tool—pulling or twisting alone won’t work and may damage your pipes.
According to a 2023 report by the Plumbing-Heating-Cooling Contractors Association (PHCC), over 68% of emergency plumbing callbacks related to DIY projects involved improper fitting removal—often leading to water damage or system failure.
Short answer: It depends on the brand and condition.
Most manufacturers (like SharkBite, FloFast, and JG Speedfit) do not recommend reusing push fit fittings after removal. Once the internal teeth and O-ring are compressed or disturbed, the seal integrity may be compromised.
However, if the fitting is undamaged and removed correctly with the proper tool, some professionals reuse them for non-critical, low-pressure applications (e.g., garden irrigation). For indoor, pressurized water lines—always install a new fitting to avoid leaks.
💡 Pro Tip: Label removed fittings as “for temporary or non-potable use only” if you plan to reuse them. Never reuse fittings on main supply lines.
Tools You’ll Need
Before starting, gather the right equipment. Using improper tools can scratch copper pipes or deform the fitting, leading to leaks.
✅ Essential Tools:
Push-to-connect release tool (brand-specific or universal)
Adjustable wrench or pipe cutter (if cutting is needed)
Clean cloth or rag
Bucket or towel (to catch drips)
❌ Avoid:
Pliers without pipe protection
Hammers or excessive force
Screwdrivers (they can puncture seals)
Most major brands sell inexpensive release tools ($5–$15) that slide over the pipe to depress the internal grab ring. Universal tools (like the SharkB.ite U016LF) work across multiple brands but always check compatibility first.
Step-by-Step: How to Remove Copper Push Fit Plumbing Fittings
Follow these steps carefully to avoid damage:
Step 1: Turn Off the Water Supply
Shut off the main water valve or the nearest isolation valve. Open a nearby faucet to drain residual pressure and water from the line.
Step 2: Dry the Fitting and Pipe
Wipe the area with a dry cloth. Moisture can make the tool slip or obscure your view of the release collar.
Step 3: Slide the Release Tool Over the Pipe
Insert the release tool over the copper pipe, not the fitting.
Push it toward the fitting until it seats fully against the fitting’s release collar (usually a visible groove or ring).
⚠️ Note: The tool must depress the internal stainless steel teeth inside the fitting. If it doesn’t click or slide in fully, you’re using the wrong size.
Step 4: Pull the Pipe Straight Out
While holding the release tool firmly against the fitting:
Grasp the pipe near the joint.
Pull straight back with steady pressure—do not twist.
The pipe should slide out smoothly in 2–5 seconds.
If it resists:
Double-check tool alignment.
Ensure the tool is fully seated.
Never force it—this can deform the fitting or pipe.
Step 5: Inspect for Damage
After removal:
Check the pipe end for burrs, scratches, or deformation. Use a deburring tool if needed.
Examine the O-ring inside the fitting for cracks or tears.
📏 Copper Pipe Prep Tip: For reinstallation, pipes must be cut squarely and free of debris. Use a pipe cutter—not a hacksaw—to avoid ovaling.
Common Mistakes to Avoid
Mistake
Consequence
Solution
Pulling without a release tool
Pipe gets stuck or fitting breaks
Always use the correct release tool
Twisting during removal
Damages grab ring or pipe surface
Pull straight—no rotation
Reusing worn fittings
Hidden leaks under pressure
Replace fittings on critical lines
Skipping pipe cleaning
Poor seal on reconnection
Wipe pipe with emery cloth before reinserting
When to Call a Professional
While removing push fit fittings is DIY-friendly, call a licensed plumber if:
The fitting is in a high-pressure main line
You notice corrosion, pinhole leaks, or green patina on copper
The pipe is embedded in a wall with no access
You’ve tried twice and the pipe won’t release
According to HomeAdvisor, 42% of DIY plumbing errors stem from overconfidence in “simple” tasks—leading to water damage averaging $3,500 per incident.
FAQ Section
Q1: Do I need a special tool to remove push fit fittings?
Yes. Push fit fittings use an internal grab ring that locks onto the pipe. Only a release tool can compress this ring to free the pipe. Pliers or wrenches won’t work and may damage components.
Q2: Can I remove a push fit fitting without cutting the pipe?
Absolutely—if you use the correct release tool. Cutting should only be a last resort when the fitting is seized or the pipe is damaged.
Q3: Are copper push fit fittings permanent?
They’re designed for long-term use but not truly permanent. Unlike soldered joints, they can be removed and replaced—making them ideal for repairs and renovations.
Q4: Why won’t my fitting release even with the tool?
Internal corrosion (common in older systems) Try cleaning the area or using a brand-specific tool.
Q5: Can I use push fit fittings on both hot and cold lines?
Yes. Most copper push fit fittings are rated for temperatures up to 200°F (93°C) and 200 PSI, suitable for standard residential hot water systems.
Q6: How long do push fit fittings last?
Manufacturers typically warrant them for 25+ years when installed correctly. Real-world performance depends on water quality, pressure cycles, and installation quality.
Conclusion
Knowing how to remove copper push fit plumbing fittings empowers you to handle repairs confidently—without risking costly water damage or calling a plumber for minor fixes. With the right tool, a few minutes of prep, and this guide, you can disconnect fittings safely and inspect your system like a pro.
🔧 Remember: Always use a release tool, never force the joint, and replace fittings on critical lines. Your future self (and your drywall) will thank you!
