Run the PEX tubing: PEX needs to be supported a minimum of every32 incheswhen running horizontally. If running vertically, it should be supported every 4 to 6 feet. (These supports are critical.)
Can you use expansion fittings on PEX tubing?
About Expansion Fittings Expansion fittings are intended for use with PEX-A tubing only, using expansion connection method. Poly expansion fittings in this category are a direct replacement for Uponor/Wirsbo EP series poly fittings and are compatible with hePEX and AquaPEX tubing brands as well as RAUPEX from Rehau and Mr. PEX tubing.
How close can PEX tubing be to a gas line?
The tubing needs to be 12 inches away from recessed lighting and three inches away from gas vents. It also shouldn’t be used in direct sunlight or for gas lines. Doing this doesn’t allow for mistakes and could make the PEX tubing installation take longer than it should or cost you money because you’ll need to buy new tubing.
Does PEX pipe need to be welded?
Many do-it-yourselfers are transitioning to PEX from copper pipes since installation doesn’t require welding or chemicals to join the tubing together. Also, fewer fittings or connections are required making these types of plumbing pipes much faster to install than metal or traditional rigid plastic.
Can you put hangers on PEX pipe?
Extra pipe support may be required during PEX tubing installation. Provide this support with plastic hangers only. Metal hangers can damage the tube. Use the hangers that keep the pipe off the stud or joist to prevent water noise transfer Using PEX tubing instead of traditional copper will save you time and headaches.
What is PEX Piping?
PEX piping (shorthand for cross-linked polyethylene) costs less than half the price of copper and installs much faster. And since it’s flexible, PEX makes remodeling jobs easier. PEX has a strong “memory;” it always wants to spring back to its original shape. So working with a coil of PEX is like wrestling with a giant Slinky. For most jobs, you’re better off buying 10-ft. “sticks” instead. You may have to pay a few cents more per foot and install a coupler or two, but you’ll avoid frustration and kinks. Even plumbers who run miles of PEX every year often buy sticks than coils.
What About PEX vs. CPVC?
A PEX supply and CPVC cost about the same. But there are a few reasons why PEX may be a better choice. First, a PEX doesn’t require glue, which means you don’t have to work in well-ventilated spaces or wear a respirator. PEX is less likely than CPVC to burst if it freezes. Also, since PEX is more flexible and available in long lengths, it can work better for ‘fishing’ through walls in remodeling situations.
Do I Need Special Tools?
Yes. When plumbing with PEX, you can use stab-in or compression fittings to make the connections, but they’re too expensive to be practical on large projects. Connections for most PEX supply jobs require a special tool. There are several PEX supply connection methods, but only two affordable enough to be practical for DIYers: crimp rings and cinch clamps.
How Do I Splice PEX Fittings Into My Existing Pipe?
SharkBite is one common brand of stab-in fitting. This method doesn’t require soldering, which can be a big time-saver. But check with your plumbing inspector if you’re planning to bury this connection in a wall or ceiling. Some areas don’t allow stab-in fittings to be concealed. Another method is to solder in a tee and a PEX supply adapter. Then slip the PEX supply tubing over the adapter and attach it with your chosen connection method (right). You can also use a stab-in tee to connect PEX fittings supply to CPVC. Read the label to find the compatible fitting.
Do I Have to Use Manifolds with PEX?
No. You can install PEX fittings supply just like you would other pipe, with main lines and branches to each fixture. But you lose a lot of the benefits of PEX with this system since it requires so many fittings. With the home-run system, you install a manifold in the utility room or some area that’s close to the main water line and water heater, and run a separate PEX tube to each fixture as shown above. This system uses more tubing, but is fast and only requires two connections: one at the manifold and another at the fixture end. You can also use a hybrid system where you run three-quarter inch hot and cold lines to a set of fixtures — for example, a bathroom — and install a smaller manifold behind an access panel. Then make short runs of one-half inch PEX water line tubing to each fixture.
Does it Meet Code?
There is no unified national plumbing code. Before starting your PEX plumbing job, check with your local inspector for specific local requirements.
Is PEX Reliable?
PEX has been used for decades in other countries, where there are thousands of homes with 30-year-old, leak-free PEX. Most of the problems with PEX systems, in the United States and elsewhere, were due to sloppy installation or faulty fittings rather than the tubing itself.
How deep should I drill PEX?
Do Know How Deep to Drill or Notch. With PEX tubing installation, drill to a maximum depth of 40 percent the depth of the wood on load bearing wood- and i-joists. Notches can go to a 25 percent depth. A non load bearing wood- or i-joist can be drilled to a maximum depth of 60 percent of the depth of the wood. Notches can go to 40 percent deep.
How to mark a run in a manifold?
Do mark each run at the manifold with a piece of thick paper and a plastic fastener around the pipe. Write on the paper with a black marker to identify where the water from the run goes, such as the bathroom sink, hot or cold water, or the basement toilet.
Can you use metal hangers on PEX tubing?
Don’t Use Metal Hangers. Extra pipe support may be required during PEX tubing installation. Provide this support with plastic hangers only. Metal hangers can damage the tube. Use the hangers that keep the pipe of the stud or joist to prevent water noise transfer.
Is PEX tubing corroded?
PEX tubing is chemically treated high-density polyethylene that’s flexible, heat resistant, and doesn’t develop pinholes or corrode. Many do-it-yourselfers are transitioning to PEX from copper pipes since installation doesn’t require welding or chemicals to join the tubing together. Also, fewer fittings or connections are required making these types of plumbing pipes much faster to install than metal or traditional rigid plastic. To make the installation process go as smoothly as possible, it’s important to remember these dos and don’ts.
What is the purpose of articles being reviewed?

Can you cut PEX tubing to exact size?
Don’t Cut Tubing to Exact Size. Doing this doesn’t allow for mistakes and could make the PEX tubing installation take longer than it should or cost you money because you’ll need to buy new tubing.
Can you install PEX tubing on outside walls?
When positioning the piping during PEX tubing installation, make sure you keep it away from areas where it could be exposed to extreme temperatures. Do not install on outside walls, crawl spaces, or attics. Only install the tubing in these areas if the pipes are insulated according to local plumbing codes.
What is expansion fitting?
Expansion fittings are intended for use with PEX-A tubing only, using expansion connection method. Poly expansion fittings in this category are a direct replacement for Uponor/Wirsbo EP series poly fittings and are compatible with hePEX and AquaPEX tubing brands as well as RAUPEX from Rehau and Mr. PEX tubing. These fittings are manufactured to ASTM F1960 standard, are lead-free compliant and are NSF certified for potable water applications.
What is PEX fitting made of?
A: Like most poly PEX fittings on the market, including Uponor, these are made using Radel polyphenylsulphone (PPSU) polymer, which has a long history of use in plumbing, medical and aerospace industries.
Can you replace Uponor fittings?
A: Yes. They can replace Uponor fittings and can be installed using Uponor, Milwaukee and Everhot expander tools. Just like Uponor fittings, they require appropriate size expansion rings and are installed in the same manner.
What is hearth.com?
Active since 1995, Hearth.com is THE place on the internet for free information and advice about wood stoves, pellet stoves and other energy saving equipment.
What era was the Allis Chalmers tractor?
3 – 1950 era Allis Chalmers tractors to haul in the wood.
Can Romex be used with PVC?
Romex is rated for 90* C it can touch, it can take the heat. Just don’t share the same holes with romex with any type of PVC or PEX because of expansion and contraction in those pipes. I have seen plenty of worn wires in my day.
Does foam insulation hurt a romex?
it won’t hurt to put a piece of foam pipe insulation around the pipe where it touches the romex. Actually around here some of the inspectors require it. I don’t know when your house was wired but if it was before 1985 romex had a lower tempature rating.
What type of fittings are used for PEX?
Hundreds of types of fittings, usually brass, are available for connecting PEX to existing copper or steel pipes, and for making connections to fixtures. Fittings are also available for connecting pipes of different sizes. The following five methods are used for making the connections watertight. Photo: amazon.com.
What is PEX tubing?
Choose the tubing best suited to your needs: PEX-A is manufactured using peroxide. This type of PEX is the most flexible of the three types and is suitable for use in all home water-supply plumbing needs.
What color is PEX?
Water flows silently through PEX, eliminating the “water hammer” noise associated with metal piping. Color-coding (red and blue) make it simple to distinguish hot and cold supply lines. PEX can be connected to existing metal supply lines with the correct fittings.
What is the advantage of PEX pipe?
PEX has a distinct advantage over these materials because of its flexibility, which allows one end of PEX pipe to connect to a PEX manifold (the main water control system) and then wind through walls and floors—uninterrupted—all the way to an individual fixture.
What type of PEX pipe is used for hot water?
Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water. Gray PEX pipe, like white, can be used for either hot or cold water (although not all DIY centers carry gray).
How long is a PEX pipe?
PEX is available in a variety of lengths, from short 10-foot pieces (for small repairs) to rolls over 500 feet long, which are used to install a home’s entire water supply system. PEX pipe ranges from 3/8- to 1-inch in diameter and its color-coding makes it a snap to identify what a specific pipe is used for. Although there are three types of PEX (see Label Lingo, below), the different colors don’t connote the distinctions; they simply make it easy for the installer to identify which lines carry hot water and which carry cold.
What is PEX pipe?
Cross-linked polyethylene (PEX), a type of flexible plastic, is currently replacing traditional copper and galvanized steel as water supply lines in both new construction and remodeling projects. You’ve probably seen rolls of blue and red PEX pipe in the plumbing aisle of your local home improvement store, but might not know that this colorful tubing now makes it possible for enthusiastic DIYers to replace their own leaky water lines instead of calling a pro. Read on to learn more about PEX—what it is, where it can be used, and all the pros and cons of this popular plumbing material.
