Polybutylene SharkBite is a transition coupling well-known for connecting different pipe materials. Unlike most couplings, polybutylene SharkBite can be installed without glue, clamps, or soldering.
That makes the installation process easy and quick. Another interesting feature is that it’s versatile. You can use it to join polybutylene pipes with PEX or HDPE pipes.
But can you use it on copper? That’s what I’ll be answering in this post as well as sharing a detailed guide on how to use these two plumbing fixtures.
Can I Use Polybutylene SharkBite on Copper?
Of course, you can use polybutylene SharkBite on copper. On their official website, SharkBite mentions that their transition coupling can be used on copper pipes.
They also proceed to highlight that the tan collar end is compatible with copper pipes. So, you shouldn’t use it on the gray end which only works for polybutylene pipes.
So, if you were wondering whether it’s possible to use polybutylene SharkBite on copper. There is your answer. But before you run off to install this transition coupling on your copper pipes, it’s important to learn how to do it correctly.
How to Use Polybutylene SharkBite on Copper?
Step 1: Cut and Clean the Copper Pipes
Some people jump straight into fitting the coupling into the pipes. But preparation is very crucial because it minimizes room for failure.
Inspect the copper pipe and cut it to your preferred length. Proceed to clean it thoroughly so that you can remove rust or debris.
Step 2: Mark the Depth of the Copper Pipe
Even though polybutylene SharkBite couplings are well known for creating tight seals, it needs to be fitted securely so that they can create a watertight seal.
This is why it’s a good idea to mark the depth of the copper pipe you intend to fit the transition coupling.
Step 3: You’re Now Ready to Insert the Transition Coupling
Using gentle force, slide the coupling into the copper pipe. Make sure that you slide until it reaches the desired depth.
Step 4: Test the Coupling
It’s always a good idea to test for leaks before completing the installation. In case you spot some leaks, gently push the SharkBite further into the copper pipe. And that’s how you can successfully install a polybutylene SharkBite into a copper pipe.
Benefits of Using Polybutylene SharkBite on Copper
Besides polybutylene SharkBite being compatible with copper pipes, there are plenty of benefits that come from using these two plumbing fixtures, which include;
• Fitting SharkBite into copper is relatively effortless. You don’t need any special skills or tools.
• Polybutylene SharkBite transition couplings are perfect for incidents such as leaking copper pipes. They offer a temporary fix.
• With these two fixtures, you don’t need to use glue, soldering, or clamps. And that speeds up the installation process.
• After installation, SharkBite on copper is easily removable. That comes in handy during repairs and replacements.
• Compared to other methods of connecting copper and polybutylene pipes, SharkBite offers a less invasive approach.
Factors to Consider When Connecting Polybutylene SharkBite to Copper
To ensure the connection is successful and reliable, I’m going to list a few things that you need to consider before using polybutylene SharkBite on copper;
• The condition of the copper pipe – As good as the transition coupling from SharkBite is, if your copper pipes are in bad condition, the connection will be weak. Assess the nature of the connection first to ensure its fit for a transition coupling.
• The ends of the copper pipe are smooth – If the ends of your copper pipe have ridges and dents then that can affect the connection. I recommend cutting the ends of a copper pipe before installation to ensure it’s smooth and flat.
• Proper alignment – To ensure proper alignment, it is important to slide the polybutylene SharkBite coupling carefully into the copper pipe.
A crooked alignment may leave space for leaks. Inspection is mandatory to confirm that the connection is properly aligned.
• Check the pressure and temperature ratings – All SharkBite fittings have a temperature rating of 200 degrees F and a pressure limit of 200 PSI.
Only use polybutylene SharkBite on copper if the water passing through will be confined to these ratings. Anything more than that will result in premature failure.
• The purity of the water flowing through – This is something that most people don’t usually consider. But impure water that is full of minerals and is acidic will accelerate the wear of the transition coupling.
Should I Sand Copper Before Installing Polybutylene SharkBite?
Even though preparation is crucial before fitting SharkBite into a copper pipe. You shouldn’t overdo it.
For instance, you do not need to sand copper pipes before installing polybutylene SharkBite. This transition coupling is designed to fit the end of a copper pipe just the way it is.
When you sand the copper pipe, you risk damaging the entry point which may lead to leaks after it has been connected with SharkBite. Even if nothing bad happens, it will be a complete waste of time and resources.
How Long Will Polybutylene SharkBite Last on Copper?
If installed correctly, polybutylene SharkBite on copper can last for up to 15 years. That’s a very long time and by the time they get damaged, they’ll have served you well.
However, there are instances when this transition coupling can get damaged prematurely in less than 2 years. This is often caused by factors such as water chlorination.
Other issues such as high water pressure and temperatures can speed up the wear of SharkBite used on copper.
As long as the transition coupling is inspected and maintained frequently, I don’t think you’ve got anything to worry about for the next 5 to 10 years.
Do You Need Professional Help in Fitting a SharkBite Coupling in Copper?
Not at all. From the steps I’ve shared earlier, we can all agree that this is one of the easiest DIY tasks. Remember, a polybutylene SharkBite coupling doesn’t even need to be installed with special tools in the first place.
So, why pay someone for a job you can do by yourself? You may however need some professional guidance. And I’m sure that I have discussed everything you need to know in this article.
What Else Can You Use Polybutylene SharkBite On?
Earlier, I mentioned that SharkBite transition couplings are versatile. Therefore, besides copper, you can use them on a wide range of materials such as PEX, CPVC, PE-RT, and HDPE pipes.
Did you know that these fittings can also be used in old galvanized steel pipes? I have also seen them being used with brass pipes.
The list of pipe materials compatible with polybutylene SharkBite is endless. However, always refer back to the manufacturer if you’re unsure about a certain pipe material.
How Do You Prevent Leaks on a SharkBite to Copper Connection?
There is only one way you can prevent leaks in a copper and polybutylene SharkBite connection and that’s by following the installation steps mentioned above.
Leaks are often caused by mistakes made during installation. For instance, if you don’t clean the copper ends or forget to deburr them, the connection will be insecure. The same applies to alignment.
Sometimes, leaks can also occur if you don’t follow the manufacturer’s instructions. Should the connection be exposed to high temperatures and pressure, the structural integrity may weaken. Nearly all causes of leaks in such a connection can be avoided.
What Issues Can You Expect from Using Polybutylene SharkBite on Copper?
I have already discussed the major issue which is leaking. But there are a couple of issues that may pop up when you use polybutylene SharkBite on copper, which include;
• Corrosion – This can either be caused by the water flowing through or the presence of two different materials.
• Code compliance – In some areas, the local code advises against using polybutylene SharkBite fittings on copper. Please confirm with the local authorities before proceeding.
• A weak seal – The fact that a polybutylene SharkBite connection can be easily connected and disconnected. If this is done continuously, the O-ring can lose its strength.
• Reliability – The ugly truth is that other connections are more durable with copper than polybutylene SharkBite.
