Which fittings are better for PEX brass or plastic?
Overall, it is hard to definitively say which of brass or plastic fittings are better for PEX plumbing as each has their own unique advantages and disadvantages. Brass fittings can help to create a more secure and permanent connection when compared to plastic fittings.
The brass fittings are also inherently more durable and have better corrosion and oxidation resistance than plastic. On the other hand, plastic fittings may not provide the same level of secure connection, though they are often cheaper and easier to install than brass fittings.
In the end, the decision on which fittings are better for PEX will come down to the specific needs of the project. If a secure and permanent connection are important, brass fittings may provide a better option.
However, plastic fittings may offer a better value in terms of cost and installation. It is important to weigh the differences between brass and plastic fittings in order to determine which is ultimately the better option for the particular project in question.
Is it OK to use plastic PEX fittings?
Yes, it is generally OK to use plastic PEX fittings for your plumbing needs. PEX, or Crosslinked Polyethylene, is a type of plastic plumbing tube with a 10-25 year lifespan. It is resistant to rust, corrosion, expansion, contraction, and has a good degree of durability.
PEX fittings come in a variety of shapes, sizes and materials, and can be used to join a variety of pipes. When used correctly, plastic PEX fittings are a reliable choice for many types of plumbing projects.
However, plastic fittings are typically not suitable for outdoor applications due to possible UV damage to the plastic material.
What is the most reliable PEX fitting?
The most reliable PEX fitting is the Crimp Ring model. It uses a copper crimp ring with a special crimpling tool to form a secure and reliable fitting. This is generally considered to be one of the strongest and most secure types of PEX fitting and it is also much easier to install than other types of fittings.
Other types of PEX fittings, such as the Expansion model, may also be reliable but can often require more skill and patience to properly set up. Additionally, using a Crimp Ring allows for easy re-tensioning if required, making it a go-to choice for many professionals.
Can you crimp plastic PEX fittings?
Yes, it is possible to crimp plastic PEX fittings. PEX piping is used for a variety of applications, such as in-floor radiant heating, water service, and plumbing. It is most commonly used in the residential market due to its ease of installation.
PEX fittings are made to be crimped using a special crimping tool and crimp rings. The method of crimping involves wrapping the fitting with a crimp ring, placing the fitting and crimp ring in the jaws of the tool, and then compressing the crimp ring around the fitting.
The force applied to the crimp ring when clamping the fitting creates a seal that prevents water from leaking around the fitting. The crimping process should be done carefully to ensure a strong and secure connection.
If necessary, extra fittings can be installed to provide extra reinforcement at connection points.
Why do PEX fittings fail?
PEX (cross-linked polyethylene) fittings can fail for a variety of reasons, such as incorrect installation, poor-quality materials, or elevated levels of chlorine in the water supply. Incorrectly installed fittings, especially those where the connection is too tight, can cause the plastic to crack or break under pressure.
Poor quality materials may not seal correctly and may cause the fittings to leak or the water pressure to push the seal open. Elevated levels of chlorine in the water supply can cause the PEX material to deteriorate over time, resulting in leaks and premature failure of the fittings.
Additionally, PEX piping and fittings should not be installed in areas where temperature exceeds 200° F, as it will cause the plastic to become brittle and may lead to costly scale buildup and/or operational failure.
Lastly, over time, fittings may become obsolete and/or unavailable, leaving homeowners unable to repair or replace their broken or faulty fitting.
Do PEX fittings ever leak?
Yes, PEX fittings can leak. Just like any other type of plumbing, PEX fittings are subject to wear, tear, improper installation, and other issues that can cause a water leak. The most common causes of PEX fitting leakage include sleeve blockage, corrosion, improper installation, over-tightening, thermocycling, and damage due to sharp tools or overzealous force.
To avoid PEX fitting leakage, make sure that you have the right tools, follow the installation instructions very carefully, and use the appropriate sleeve size. Additionally, it’s important to use high quality PEX fittings that have earned the necessary certifications.
Performing regular maintenance on your plumbing system can also help prevent PEX fitting leakage. This includes checking the fittings regularly for any signs of damage or wear and fixing any leaks that may occur as soon as possible.
What should you not do with PEX?
It is important to understand that PEX is a very versatile material, but that it is not capable of doing everything. For example, you should not use it to support outdoor structures, such as part of a deck or fence, as it is susceptible to sunlight and other weather conditions.
PEX should also not be used with fittings made of materials other than brass, like steel or copper. Additionally, PEX should not be used in applications where temperatures exceed 200°F or be exposed to direct sunlight for long periods of time.
PEX is not suitable for swimming pools or for burying in the ground. When installing PEX, sharp bends should be avoided, and it is best to use bending tools to help. Lastly, PEX should never be used near open flames or combustible materials, as it is combustible.
Is it better to crimp or clamp PEX?
Generally speaking, crimping is the preferred method of attaching PEX fittings to PEX pipes. The ends of PEX pipes may be crimped using special PEX crimping tools and PEX crimp rings or clamps of appropriate sizes for the fittings used.
Crimp rings are usually made from copper or stainless steel, whereas PEX clamps are usually made from stainless steel.
The process of crimping involves the squeezing of the fitting and PEX pipe together with a PEX crimp tool. The crimp ring gets crimped tightly around the fitting, forming a watertight seal. This method is more reliable and less prone to drips or leaks compared to PEX clamping systems.
However, it is important to make sure the correct size of crimp ring is used for the fittings and also to watch for signs of crushed pipes.
Clamping using PEX clamps is another popular method of connecting PEX fittings to PEX pipes. PEX clamps are stainless steel bands with special teeth that grip onto the PEX pipe when the band is tightened.
PEX clamps, like crimp rings, offer an effective and secure connection. The main benefit of using PEX clamps is that if there are any problems with the connection, the clamps can be loosened and adjusted.
In conclusion, both crimping and clamping are viable methods for connecting PEX fittings to PEX pipes. However, crimping is considered the preferred method as it is more reliable and less likely to cause leaks compared to PEX clamps.
Regardless of method used, it is important to use the correct size of fitting and crimp ring or PEX clamp, and to watch for any signs of crushed pipes.
What is the life expectancy of PEX plumbing?
PEX plumbing is a modern plumbing solution made of cross-linked polyethylene (PEX) piping. This type of pipe offers increased flexibility and durability in comparison to traditional copper piping, as it does not corrode, freeze, or burst.
As it is so reliable, PEX plumbing typically has a life expectancy of over 25 years. However, this largely depends on the quality of the PEX material used and how it is maintained in the long-term. Factors such as environmental conditions, quality of installation and water chemistry can affect PEX life expectancy, but if regularly maintained, it could last even longer.
Additionally, PEX plumbing is designed to handle temperatures as cold as -40° F and as hot as 200°F which can provide long-lasting use in climates around the world.
Which is better PEX crimp or expansion?
When it comes to PEX crimp vs. expansion, there is no clear answer as to which is better. It really boils down to preference and the specific needs of the application.
PEX crimp connections are made using a tool which crimps a copper or stainless steel ring onto the PEX pipes and fittings, creating a watertight seal. This type of connection is typically used for indoor applications and is one of the most common methods of PEX installation.
PEX crimp is generally considered the simpler of the two methods and is easier to install, making it the better choice for a DIY homeowner or contractor who isn’t as experienced with PEX work. PEX crimp is also usually the more cost-effective option when comparing materials, labor, and tools.
On the other hand, PEX expansion connections are made using a mechanical expansion tool and a copper or stainless steel expandable ring. The expanded ring creates a strong, watertight seal when joined together with the pipes and fittings.
This type of connection is more reliable and durable than PEX crimp and is better suited for outdoor applications due to its increased resistance to freezing temperatures. PEX expansion can be more difficult to install and requires more specialized tools, making it the better choice for a professional contractor who is experienced with PEX work.
In conclusion, both PEX crimp and expansion connections have their own advantages and disadvantages and it really comes down to preference and the specific needs of the application.
