SharkBite fittings are a quick and easy way to connect pipes, but you might wonder if they’re supposed to spin after installation. Let’s dive into this common question and clear up any confusion!
### What are SharkBite Fittings?
SharkBite fittings are push-to-connect plumbing fittings. They’re designed to create a watertight seal without soldering, gluing, or using special tools. This makes them a favorite for DIYers and professionals alike for quick repairs and installations.
### The Big Question: Should They Spin?
The short answer is **yes, a SharkBite fitting *should* spin freely after it’s properly installed.** This doesn’t mean it’s loose or leaking. The spinning is actually a sign that the fitting is doing its job.
### Why Do They Spin?
The ability to spin comes from the way SharkBite fittings are designed. Inside the fitting, there’s a collet (a kind of clamping ring) with stainless steel teeth that grip the pipe. There’s also an O-ring that creates the watertight seal.
The collet grips the pipe tightly enough to prevent it from pulling out, but it still allows the fitting to rotate around the pipe. This rotational freedom is important because:
* **It prevents stress on the pipe:** If the pipe moves or shifts slightly (due to temperature changes, building movement, etc.), the spinning action prevents that stress from being transferred directly to the fitting or the joint.
* **It allows for adjustments:** The spinning can make it easier to make slight adjustments to the alignment of your pipes after the fitting is installed.
### How to Know if Your SharkBite Fitting is Properly Installed
Just because it spins doesn’t automatically mean it’s installed correctly. Here’s what to look for:
1. **Proper Insertion Depth:** Make sure the pipe is inserted fully into the fitting, past the internal stop. SharkBite even provides depth gauges to help you mark the pipe before insertion for accuracy.
2. **No Leaks:** This is the most obvious sign. After installation, turn the water supply back on and check for any leaks around the fitting.
3. **Secure Grip:** While it should spin, the fitting shouldn’t slide back and forth on the pipe. It should feel firmly attached.
### Steps for Installing SharkBite Fittings Correctly
1. **Cut the Pipe Cleanly:** Use a proper pipe cutter to ensure a square, burr-free cut.
2. **Deburr the Pipe:** Remove any burrs or sharp edges from the cut end of the pipe. This is important for protecting the O-ring inside the fitting.
3. **Mark the Insertion Depth:** Use a SharkBite depth gauge to mark the correct insertion depth on the pipe. This ensures the pipe goes in far enough to engage the gripping mechanism.
4. **Push to Connect:** Push the fitting onto the pipe until it reaches the depth mark. You should feel a slight click or resistance when it’s fully seated.
5. **Test the Connection:** Turn the water back on and check for leaks. Also, gently try to pull the fitting off the pipe. It shouldn’t budge.
### Common Mistakes to Avoid
* **Using Damaged Pipe:** Make sure the pipe is free from dents, scratches, or corrosion in the area where the fitting will be installed.
* **Not Inserting the Pipe Fully:** This is the most common mistake. If the pipe isn’t fully inserted, the fitting won’t seal properly, and it will leak.
* **Forgetting to Deburr:** Burrs can damage the O-ring and cause leaks.
* **Using on Certain Materials:** SharkBite fittings are designed for use on PEX, copper, CPVC, PE-RT, and SDR-9 HDPE pipe. Don’t use them on other materials unless the fitting is specifically rated for it.
* **Reusing Old Fittings:** It is recommended to use new fittings for each installation.
### FAQ About SharkBite Fittings and Spinning
**Q: My SharkBite fitting spins *too* easily. Is that a problem?**
A: If it spins very freely and feels loose, double-check that the pipe is fully inserted. If it is, there may be an issue with the fitting itself, and it might need to be replaced.
**Q: Can I use SharkBite fittings for hot water lines?**
A: Yes, SharkBite fittings are rated for both hot and cold water applications.
**Q: Are SharkBite fittings a permanent solution?**
A: While they can be used as a permanent solution, many plumbers consider them best for temporary repairs or situations where soldering isn’t possible or practical. They are code approved for permanent installations, so if properly installed, they will last a long time.
**Q: Can I bury SharkBite fittings underground?**
A: SharkBite fittings can be buried if they are wrapped properly and protected from the elements. Check your local plumbing codes.
**Q: How do I remove a SharkBite fitting?**
A: You’ll need a special SharkBite removal tool. This tool pushes the collet back, releasing the grip on the pipe.
### Conclusion
So, are SharkBite fittings supposed to spin? Yes, a properly installed SharkBite fitting should spin freely. This is a normal part of its design and helps prevent stress on your plumbing system. Just make sure you follow the correct installation steps and double-check for leaks to ensure a reliable, long-lasting connection.
