Homeowners tackling a plumbing leak or upgrading old pipes often ask: “Can SharkBite be used on a section of replaced plumbing?” It’s a smart question—after all, you want a fix that’s fast, reliable, and code-compliant. Whether you’re patching a burst copper line or swapping out corroded galvanized pipe, SharkBite fittings offer a popular no-solder solution. But are they truly suitable for partial repiping? Let’s dive into the facts, backed by plumbing experts and real-world use cases.
What Is a SharkBite Fitting?
SharkBite is a brand of push-to-connect plumbing fittings that join pipes without soldering, gluing, or threading. Introduced in the early 2000s, these fittings use a stainless steel grab ring and an EPDM O-ring to create a watertight, secure connection on copper, PEX, CPVC, and even some types of PVC pipes.
According to the Plumbing-Heating-Cooling Contractors Association (PHCC), push-to-connect fittings like SharkBite are now widely accepted in residential and light commercial applications—when installed correctly.
“SharkBite fittings are certified to ASTM and NSF/ANSI standards, making them suitable for potable water systems,” says master plumber James Rivera of Austin, TX, with 22 years of field experience.
These fittings are rated for up to 200 PSI and temperatures up to 200°F (93°C), well within standard residential plumbing conditions.
Can SharkBite Be Used on a Section of Replaced Plumbing?
Yes—absolutely. SharkBite fittings are specifically designed for use in partial plumbing repairs, including when replacing only a section of pipe. This makes them ideal for:
- Fixing a leaking copper pipe under a sink
- Replacing a corroded segment of galvanized steel
- Transitioning from old CPVC to new PEX lines
- Emergency repairs during winter (no open flame needed)
The key is proper pipe preparation and code compliance in your area.
⚠️ Note: While SharkBite is approved by the Uniform Plumbing Code (UPC) and International Plumbing Code (IPC), some local jurisdictions (like parts of California or New York City) may have restrictions on push-fit fittings in concealed walls. Always check with your local building department.

When to Use SharkBite in Repiping Projects
✅ Ideal Scenarios:
- Emergency repairs (no torch = safer in tight spaces)
- Retrofitting older homes with mixed pipe materials
- DIY-friendly upgrades where soldering skills are lacking
- Temporary fixes that may later become permanent (SharkBite offers a 25-year warranty when installed per instructions)
❌ When to Avoid:
- Underground or in-slab installations (unless using SharkBite’s 埋设-rated fittings with protective sleeves)
- High-vibration areas (e.g., next to water heaters with loose mounts)
- Systems with frequent pressure surges or water hammer (consider installing a water hammer arrestor)
Step-by-Step: Installing SharkBite on Replaced Plumbing
Follow these exact steps to ensure a leak-free, long-lasting connection:
- Shut off water supply and drain the line completely.
- Cut out the damaged section using a tubing cutter (for copper) or pipe cutter (for PEX/CPVC). Ensure the cut is square and burr-free.
- Deburr the pipe end with a deburring tool or fine sandpaper. Even a tiny burr can damage the O-ring.
- Mark insertion depth on the pipe using the SharkBite depth gauge (usually printed on the fitting bag).
- Push the pipe straight into the fitting until it hits the stop. You should hear a soft click.
- Verify full insertion by checking the release collar—pipe should be flush with the fitting’s end.
- Turn water back on slowly and check for leaks.
🔧 Pro Tip: Use SharkBite’s test caps to pressure-test the section before closing walls. Run water at 60 PSI for 15 minutes—no drops or drips should appear.
SharkBite vs. Traditional Methods: Pros & Cons
| Feature | SharkBite | Soldered Copper | PVC Glue Joint |
|---|---|---|---|
| Installation Time | 2–5 minutes per joint | 10–20 minutes | 5–10 minutes (plus cure time) |
| Skill Required | Beginner-friendly | Intermediate/Expert | Beginner |
| Reusability | ✅ Yes (with release tool) | ❌ Permanent | ❌ Permanent |
| Concealed Use | Allowed in most codes | Universally accepted | Allowed |
| Cost per Fitting | $3–$8 | $0.50 (plus torch, flux, solder) | $1–$3 |
| Longevity | 25+ years (warranty-backed) | 50+ years | 25–50 years |
While soldered joints last longer, SharkBite’s speed, safety, and reversibility make it a top choice for spot repairs.
Common Mistakes to Avoid
Even experienced DIYers make these errors:
- Reusing a fitting without a release tool → damages the grab ring
- Forgetting to clean pipe ends → debris compromises the seal
- Installing on wet pipes → water prevents full insertion
- Using on non-approved pipe types (e.g., black iron, polybutylene) → voids warranty
Always refer to SharkBite’s official installation guide—never assume compatibility.
FAQ Section
Q1: Can I use SharkBite to connect copper to PEX in a replaced section?
A: Yes! SharkBite makes transition fittings specifically for copper-to-PEX, PEX-to-CPVC, and other combinations. Just ensure both pipe types are clean, dry, and fully inserted.
Q2: Are SharkBite fittings permanent?
A: They’re designed to be permanent when installed correctly. The 25-year warranty reflects their durability. However, they can be removed and reused with a SharkBite demounting clip.
Q3: Do SharkBite fittings leak over time?
A: Rarely—if installed properly. Most leaks result from incomplete insertion, pipe burrs, or excessive pipe movement. Always support pipes within 8–12 inches of the fitting.
Q4: Can I use SharkBite behind drywall or in walls?
A: Yes, in most U.S. jurisdictions. The IPC and UPC allow push-to-connect fittings in concealed spaces. However, California and NYC have exceptions—verify local codes first.
Q5: How do I remove a SharkBite fitting if I make a mistake?
A: Use a SharkBite release tool (sold separately). Slide it over the pipe and push against the fitting’s release collar to disengage the grab ring. Never yank or twist.
Q6: Is SharkBite okay for hot water lines?
A: Absolutely. SharkBite fittings are rated for up to 200°F (93°C), which exceeds typical residential hot water heater settings (120–140°F).
Conclusion
So—can SharkBite be used on a section of replaced plumbing? Yes, and it’s often the smartest, safest choice for partial repiping jobs. With proper installation, these fittings deliver professional-grade reliability without the hassle of torches, glue, or threading tools.
Whether you’re a weekend warrior or a seasoned contractor, SharkBite offers speed, flexibility, and peace of mind. Just remember: prep the pipe, check local codes, and support your lines.
