What is PEX pipe and what is it used for?

PEX, or cross-linked polyethylene, is a flexible plastic pipe used for water supply plumbing. It is an alternative to copper and CPVC pipe for both whole-home repipes and new construction plumbing. PEX is flexible enough to be routed through walls with fewer fittings than rigid pipe, is resistant to scale buildup and corrosion, and is approved by California plumbing code for residential and commercial water supply applications.

Is PEX safe for drinking water?

Yes. PEX pipe certified to NSF 61, which is the standard for drinking water system components, is safe for use in potable water systems. All PEX pipe installed by our licensed plumbers meets California code requirements for drinking water supply plumbing.

What are the advantages of PEX over copper?

PEX is more flexible than copper, which reduces the number of fittings and connections required and makes installation faster. It is resistant to scale and mineral buildup, does not corrode, is less expensive than copper, and handles freeze-thaw cycles better than rigid copper pipe. It is a strong choice for repipe projects in homes where corrosion of existing copper has been a problem.

What are the disadvantages of PEX compared to copper?

PEX cannot be used outdoors where it is exposed to UV light, which degrades the material. It requires special crimp or clamp fittings rather than standard threaded or soldered connections. Some homeowners and buyers prefer copper for its decades-long track record in residential plumbing. Our technicians discuss the tradeoffs honestly before recommending one material over the other.

What is a PEX manifold system?

A PEX manifold system runs individual PEX lines directly from a central distribution manifold to each fixture in the home rather than branching off a main trunk line. Each line has its own shutoff at the manifold, allowing any single fixture to be shut off without turning off water to the rest of the home. This is more flexible and easier to service than traditional trunk-and-branch layouts.

How long does PEX plumbing last?

PEX pipe is rated for a lifespan of 25 to 50 years or more in normal conditions. The fittings and connections used with PEX are also rated for long service life when properly installed. PEX is a relatively newer material in widespread residential use compared to copper, but extensive testing and real-world performance data support its long-term durability.

Does PEX work with hot water supply lines?

Yes. PEX is rated for use in both hot and cold water supply lines up to 200 degrees Fahrenheit and 100 PSI, which exceeds the operating conditions of residential hot water supply plumbing in virtually all applications.

Can PEX be used for a whole-home repipe?

Yes. Whole-home repiping using PEX is one of the most common repipe applications. Downey Plumbing, Heating and Air Conditioning has completed PEX repipe projects in Downey-area homes of all ages. PEX's flexibility makes it particularly practical for routing new supply lines through existing wall cavities with minimal disruption. Call [phone] to schedule a repipe evaluation.

Does PEX require a permit for installation?

Yes. PEX plumbing installation, whether for a full repipe or new supply line runs, requires permits and inspection in California. Downey Plumbing, Heating and Air Conditioning handles all permit applications and coordinates inspections for every PEX installation project.

How is PEX connected at fittings?

PEX fittings use one of three connection methods: crimp rings pressed over the fitting with a crimp tool, clamp rings compressed with a clamp tool, or expansion fittings where the pipe end is expanded and slipped over a fitting that the pipe contracts around as it cools. All three methods are code-approved when performed with the correct tools and fittings.

Can PEX be used for outdoor plumbing?

Standard PEX pipe cannot be used in outdoor locations exposed to direct sunlight because UV radiation degrades the material over time. For outdoor supply line runs, the pipe must be either buried below grade, protected in conduit, or copper should be used. Our technicians advise on the appropriate material for each part of your specific project.

Is PEX or copper better for a whole-home repipe?

Both are good choices and the better option depends on your specific situation. Copper has a longer track record in residential plumbing and some buyers prefer it. PEX is more flexible, easier to install in existing walls, and less expensive. If your home has a history of copper corrosion from aggressive water chemistry, PEX eliminates the corrosion concern. Our technicians explain the specific tradeoffs for your home before recommending a material.

How much does a PEX repipe cost?

Downey Plumbing, Heating and Air Conditioning provides upfront pricing after an on-site assessment. Repipe costs depend on the size of the home, the number of fixtures, and access conditions. Call [phone] to schedule a repipe evaluation and receive a clear estimate.

Can Downey Plumbing install PEX for commercial applications?

Yes. Downey Plumbing, Heating and Air Conditioning installs PEX plumbing for commercial applications including office buildings, retail facilities, and multi-unit residential buildings where PEX is code-approved for the specific application. Call [phone] to discuss commercial PEX plumbing installation.

Does PEX pipe affect water taste or odor?

NSF 61-certified PEX pipe does not impart taste or odor to the water it carries under normal operating conditions. Some new PEX installations may have a faint plastic odor initially that dissipates after flushing. All PEX installed by our team is certified-grade pipe that meets drinking water safety standards.

What is Pex Pipe?

PEX stands for cross-linked polyethylene and is a type of plastic tubing that has been used in residential and commercial plumbing systems for the past 50 years. PEX can be used for water service lines, hydronic heating systems, radiant floor heating, snow melting, and many other applications.

It is generally preferred to traditional copper and galvanized steel for water supply lines. PEX is available in red, blue, and white colors to distinguish hot and cold water lines from the main supply.

How Does It Work?

PEX tubing works through an expansion process. The pipes are expanded using a special tool that puts an amount of force on the pipe. This creates the necessary pressure for your plumbing system, preventing leaks and other problems.

PEX piping systems are also designed to be very durable, withstanding extreme high and low temperatures. This means that it is a great choice for harsh climates where the temperature can fluctuate dramatically throughout the year. PEX piping systems are also much more resistant to corrosion than copper or galvanized steel.

What Are The Benefits of PEX Piping?

Some of the many advantages of PEX piping are:

Affordable

The materials used for PEX piping are much cheaper than those used for copper or galvanized steel. This means that the cost of a plumbing system installation is significantly lower when using PEX pipes and fittings.

Absence of Mineral Buildup

When properly maintained, PEX piping systems are less likely to accumulate mineral buildup and other debris. This can lead to an improved flow rate and could help prolong the life of your system.

Low Carbon Footprint

Compared to other plumbing materials, PEX piping systems are much more environmentally friendly. This is because the manufacturing process of PEX requires fewer resources and produces less waste than traditional materials.

Acid Resistant

Another reason why PEX is preferred to copper for water supply lines is because it is more resistant to acids and other corrosive materials. Your PEX piping system will last longer than a traditional copper system.
