So, to answer the question: yes, PEX failure is essentially the new polybutylene failure. Is PEX plumbing bad? It depends on how it’s being used.
Is PEX more durable than copper?
PEX tubing is more durable than copper tubing and is used in countless applications, such as radiant heating systems for residential and industrial plumbing. The average life of PEX for plumbing purposes is well over 50 years. What is the lifespan of PEX?
Is PEX piping better than CPVC?
You heard that right. However, PEX works better than PVC and CPVC because PEX is purely designed for indoor installations. Summing up, choosing between PVC, PEX, and CPVC is not an easy job for someone who is not familiar with all these three pipes.
Why is PEX plumbing bad?
Why is PEX Plumbing Bad?
- You can’t use PEX in outside as it is highly susceptible to UV light.
- PEX is semi-permeable. ...
- PEX can tolerate up to 125° F. ...
- Water can be contaminated with bacteria easily as PEX is not antibacterial like copper pipe.
- If your home is also a place of mice, then you have to be careful because mice love to chew it and can go through it.
Are PEX pipes better than copper pipes?
The general rule of thumb is copper pipes are better suited for outside applications than PEX pipes are. But either PEX or copper pipes can be used indoors. It's up to you. Here’s where I ultimately stand on the issue of PEX vs. copper pipes: PEX is better because it’s much easier to install than copper pipes and much cheaper.
Is PEX same as polybutylene?
PEX tubing is cross-linked polyethylene. Even though they are both plastic, PEX tubing has different properties than polybutylene. PEX is tougher, can withstand heat better, and harder to cut through than polybutylene. It's been used safely for portable water in the United States for the past two decades.
Which is better PEX or polybutylene?
One advantage that PEX has over PB is its greater tolerance to high pressures. Different manufacturers may have different numbers, but PEX will always have greater pressure limits than PB. So if you will be pumping water, or the pipes will be exposed to the cold, PEX is a better option than PB.
What's the difference between PEX pipe and poly pipe?
The main difference between the two is manufacturing. In PEX, the polymer chains are connected to each other and are called Cross linking, but it does not take place in PB pipes. Due to the cross-linked of chains, it results in revised material distinctiveness that is quite favorable for PEX.
What did PEX replace?
PEX pipe is a newer alternative to copper and galvanized piping. First introduced in the 1980s, most plumbers now fit new construction homes with PEX, as well as remodeling projects. PEX pipe is a cross-linked polyethylene flexible tubing that is blue and red in color.
When did they stop using Poly-B piping?
1998Some manufactures stamped on the pipe that it was not to be used on continuous circulating hot water lines. Poly-B piping was produced from polybutylene resin and in the spring of 1998, manufacturers stopped producing Poly-B piping because suppliers suspended production of this resin.
Can I use PEX fittings on polybutylene pipe?
PB has the same outside diameter as PEX of the same nominal size, but outside diameters differ slightly between the tubing types. This means that you should not use PEX fittings on polybutylene, but that you can use PEX crimping rings and PEX crimping tools on barbed PB connections.
Is all grey pipe polybutylene?
Polybutylene pipes used for interior applications are generally gray in color but may also be black. PB pipes used outside may be gray, blue or black. PB pipe is flexible, not rigid. Polybutylene pipes may be stamped with the code: PB2110.

What is grey plastic plumbing pipe called?
Polybutylene pipePolybutylene pipe is a gray plastic tubing that was commonly used as a water-supply plumbing pipe between 1978 and 1995, at which time it was discontinued due to reports of pipes rupturing. 1 In new construction, it was replaced by copper or more dependable forms of plastic pipe, such as CPVC and PEX.
Should I redo my plumbing with PEX?
If just a pipe or a section of your copper plumbing system is leaking, you could just replace it with PEX piping. But if you have an old copper plumbing system that leaks frequently in different areas of your home, you may want to consider a whole-house repipe.
When should you not use PEX pipe?
PEX plumbing is fine inside the walls of a home, no matter the temperatures as it can be covered with insulation. However, one of the disadvantages of PEX plumbing is it cannot be used outdoors in cold climates as there is no way to cover them and protect them from freezing temperatures.
What is the life expectancy of PEX plumbing?
50 yearsPEX: Due to its flexibility and durability, PEX piping should last at least 50 years. PVC / CPVC: Under typical conditions, these pipes should last up to 100 years.

Polybutylene pipes used for interior applications are generally gray in color but may also be black. PB pipes used outside may be gray, blue or black. PB pipe is flexible, not rigid. Polybutylene pipes may be stamped with the code: PB2110.
Can you crimp polybutylene pipe?
Transition from polybutylene to PEX pipe. Includes two color-coordinated crimp rings – the black crimp ring is for PEX pipe, while the copper-colored crimp ring is for polybutylene pipe. Certified for use in potable water and hydronic heating systems. Compatible with PEX and polybutylene pipe.
What should PEX pipe be replaced with?
There are trade-offs with all replacement options. Ultimately, our customers want their PEX or poly pipes replaced with a material that’s going to last and not empty their bank account.
Why is PEX easy to install?
One of the reasons, PEX is easy to install is because it’s basically a flexible hose that doesn’t have the traditional joints of other pipes. So, most people that don’t like CPVC complain about the need for properly creating those joints. Creating the pipe joints for CPVC takes more time & skill.
What if I have PEX piping under my house?
If there is a failing pipe under the house that can’t be accessed because it is under a concrete slab, Plumbing Express will repipe a home and bypass the pipes that are under the slab.
What is the difference between CPVC and PEX?
Another big difference between CPVC and PEX pipes is the way they connect to other pipes. CPVC, like many plumbing pipes, needs to have the connection and joints sealed. PEX, however, uses a crimping method, which has its own host of problems.
How to repair a PEX pipe?
To repair a PEX pipe leak, the best thing to do is cut out the section of failed pipe and re-crimp a new piece of pipe into the line. If the PEX pipe in the system is failing, then it is likely that another leak will develop on the adjacent pipe.
What happens if you don't crimp PEX?
For example, if PEX is not crimped with the proper tools or methods, then you will have leaks. CPVC basically uses a solvent to create a chemical weld between the pipe and the fitting. Like any type of plumbing pipe, it’s important that CPVC be installed with the proper tools & methods.
When was PEX pipe used?
In the past, PE X pipe was commonly used to replace failing polybutylene. Polybutylene was installed in more than 10 Million homes between the 1970’s and mid-1990’s! ( 1) Unfortunately, PEX piping was popular with new home construction for a long time. As polybutylene began to fail – which ultimately led to a massive class action lawsuit ( 2) ...
Which is better, PEX or polybutylene?
PEX fittings are also better if you are willing to pump up very hot water. Since PEX is much more tolerant to heat, the plastic would not melt in any way. PB or polybutylene on the other hand may have more corrosion resistance, again due to its structural bonding in the material.
How do you connect polybutylene to PEX?
Many people do not want to add the extra plumbing costs, which can be quite high based on the area you live in.
Are PEX and polybutylene fittings the same?
When it comes to using transition s or connectors, one of the most common questions that are asked by many is whether PEX and polybutylene fittings are the same.
Can I use PEX crimp fittings on a polybutylene pipe?
If you wish to use PEX crimp fitting on polybutylene pipe, it can only work if you use a specific type of coupling. In this case, you may use a brass barbed one that would fit either of the pipes.
Is all GREY pipe polybutylene?
Indeed, polybutylene pipes are mostly indicated with the color grey. However, you may also find variations in colors like white or silver to indicate PB pipe as well.
Why are PEX fittings weak?
Due to similar issues with chlorine, PEX plumbing fittings may become weak over a long period of time. You may want to remember that in the United States, PEX fittings have been chosen over PB and the latter has been banned in the USA.
What is the difference between PEX and PB fittings?
The first of many differences between the two fittings is how PEX pipes have cross-linking polymer chain which is not the case in Polybutylene or PB pipes.
What type of fittings are used for polybutylene?
The outside diameter of PB tubing is the same as for PEX, CPVC, and copper pipe so using push-fit fittings is one option you can use. The other is to use a specific transition fitting designed for transitioning between two different materials.
When was polybutylene pipe used?
Polybutylene pipe is a gray plastic tubing that was commonly used as a water-supply plumbing pipe between 1978 and 1995 , at which time it was discontinued due to reports of pipes rupturing. In new construction, it was replaced by copper or more dependable forms of plastic pipe, such as CPVC and PEX.
How to fix a leaking PB pipe?
The best solution is to use a transition coupling to convert that section to PEX. You can transition close to the leak, but if possible, follow the length of pipe and replace as much of the pipe as you can reach.
Can you replace polybutylene plumbing?
If your home still has polybutylene (PB) plumbing pipe, it is very likely to eventually fail. So it is a good idea to be proactive and replace it. Mobile homes in particular were often plumbed with PB tubing, and PB was also frequently used in standard stick-built construction during the 1970s and through the mid-1990s.
Can you use push on couplings to replace a PB pipe?
When replacing large sections of pipe, you can also use push-on couplings to transition from PB to PEX, CPVC, or copper. It is a great way to break up an overall repiping project into segments if you don’t want to do it all at once. Connect to the PB pipe with a push-on coupling and run the new pipe from that point.
Can you use transition couplings to connect a PEX riser to a PB system?
When installing or replacing a shower valve or other valve inside the wall, it is best to use a transition couplings to connect a new PEX riser to the PB system, especially if there won't be an access panel. This would be a good time, though, to install an access panel to make future work easier.
Can you repair PB pipe?
Repairs to PB piping is very difficult since neither PB plumbing pipe nor the Quest fittings used to connect it are commonly made or sold anymore. The standard solution to problems, then, is to make repairs to the damaged sections of PB by transitioning to another type of pipe, or even to repipe the entire system.
