Is a PEX manifold worth it?
Benefits of Plumbing Manifolds While copper systems are reliable and cost-effective, PEX systems are highly flexible and may be more energy-efficient. During cold snaps, they also resist freezing. As one of the most important components of a residential plumbing system, the plumbing manifold earns its keep.
What are PEX manifolds for?
A PEX plumbing manifold provides a plumbing hub for modern, residential plumbing systems that distributes water to various zones throughout the home. The PEX manifold serves as a convenient control mechanism for your homes plumbing system.
Can PEX be connected directly to a water heater?
PEX tubing may be connected directly to residential eledctric tank or tankless (instantaneous) water heaters, if the local code and manufacturer's instructions allow. When connecting PEX tube to gas tank or tankless water heaters, the tube must be kept at least 6 inches away from the exhaust vent of the heater.
Does a PEX manifold reduce water pressure?
PEX plumbing systems don't allow the water pressure to drop.
Where should a PEX manifold be located?
If you have PEX pipe for your water supply lines, you already have a PEX manifold somewhere in your home. It's usually hidden behind a removable wall panel in your utility or laundry room, and some homeowners may not even be aware of its presence.
How many years will PEX last?
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. Keep in mind that PVC pipes are often used for drainage because extreme heat can damage them.
Where should you not use PEX?
You can't install PEX in high heat areas like near recessed lighting. This also means you can't connect PEX directly to a hot water heater, but you can use a connecting material to do this. PEX is semi-permeable, which means liquid can enter the pipe. When it comes to safety, PEX isn't antibacterial.
Is Blue PEX OK for hot water?
Color-Coded: Red PEX pipes can be used for hot water supply lines, blue PEX for cold water supply, and white for either hot or cold. These colors are just for your convenience. Plumbing code does not require the pipe color to match the type of water supply.
Can PEX hot and cold touch?
Hot and Cold Water Lines Should Never Touch The picture above is of PEX hot and cold water lines that have been run through the framing and are touching each other the entire way. This has passed the rough plumbing inspection and is ready for insulation and drywall.
Do mice eat PEX?
Mice and rats will chew through anything they can, including plastic, so PEX tubing is at just as much risk as the plastic-coated wiring in a car or an HVAC unit. While all rodent damage can be expensive, if rodents chew through a home's PEX water pipes, the result can be disastrous.
Does PEX a burst on a cold weather?
The truth is, as with any piping, PEX is still vulnerable to freezing if the temperature drops low enough. But thanks to its flexible material, the plastic expands under the pressure of the freeze, significantly reducing the chance of bursting. That means your house is unlikely to flood due to a burst PEX pipe.
At what temperature do PEX pipes burst?
It has also been overtaking copper and CPVC because of its flexibility compared to copper and although PEX might freeze, unlike PVC, it would not burst. In general, PEX would freeze when surrounding temperatures reach 20 degrees Fahrenheit—especially if the water line is uninsulated.
Why do you need a PEX expander?
Using the expansion tool, you enlarge the pipe and sleeve in order slide in the fitting. Because PEX A is expandable, the material's memory will ensure that it will shrink back to its normal size, tightening snugly around the fitting.
Do manifolds add power?
To put it in simpler terms, the arrangement of a manifold means that your engine has to fight its exhaust, thus reducing engine performance and power output. Since an exhaust header gives each cylinder an individual pipe, it doesn't face this problem. The pipes also maximize an effect called 'scavenging'.
Why is PEX not allowed?
Rodent Risk Factors While pest experts don't know whether rodents chew through PEX to get to the water inside or simply because it's there, PEX and rodents can be a dangerous combination. Local building codes in some communities may not permit the installation of PEX if rodent infestations are common.
What should you not do with PEX?
No single pipe/tubing system used in the US has been 100% problem free, and PEX is no exception. Some of the disadvantages of PEX include: It cannot be used outside. It cannot be recycled.

Why do I put manifolds in my house?
If you need to shut off a room its easy to do without interrupting the rest of the house. Also, it helps balance pressure so you dont get a burst of hot water in the shower when someone flushes a toilet. I put manifolds in my house when I redid it to PEX; one for hot, one for cold.
Why does Pex hold less water?
It means it will hold less water when the water is not moving. Pex has a lower friction coefficient (it's slipperier) so you can move move the same amount of water through a slightly smaller diameter pipe. The water moves a little faster.
Is it bad to have a manifold?
If he does not use a manifold then you are just installing like a direct replacement for copper. That's not necessarily bad, but you lose some of the advantages of having a manifold where you can shut off each line individually and work on one fixture while leaving everything else on. The remote shutoff is really convenient when you need to replace an individual shutoff valve for a toilet or a sink.
How Much Does PEX Manifold Cost?
Depending on your needs and the type you choose, most PEX manifold units range between $27-$200 in cost. The pricing will also depend on if you’re buying just a few smaller units or the entire Manabloc with several ports.
Why are Propex manifolds so difficult to install?
ProPEX manifolds are more difficult because you need a special expander tool and ProPEX rings to secure the tubing. They are available in plastic or copper and come in different sizes from three to 12 outlets. Crimp Style manifolds are copper and require crimp rings and a crimp tool to attach.
What is a Pex manifold?
Pex manifolds are a fairly new way of running plumbing in your home. Pex is an acronym for cross-linked polyethylene. Rather than using the typical old rigid piping system, the Pex tubing is a more forgiving and flexible material that has a variety of incentives for using it over copper pipes. The Pex manifolds include Viega, CMI, Vivo, Apollo, ...
What color are Pex tubes?
The tubes are color-coded with blue for cold and red for hot for easy reading. It also includes both Pex press and Pex crimp.
How many square feet does a CMI manifold cover?
This CMI manifold comes in five different sizes from two ports to eight ports depending on your needs. The two-port manifold can handle 800 square feet while the eight-port manifold can cover about 1,800 to 2,000 square feet. It is already pressure tested and pre-assembled so all you have to do is mount it and connect the hoses.
What is a manifold system?
The manifold is the system that supplies water into the lines throughout your home. Each one has a variety of different fittings, end caps, and adapters to customize the manifold the way you need it. But there are certain things to look for that you may need to know.
Why use push fit manifolds?
Push-Fit manifolds are faster and easier to install when using multiple water lines. The branches have simple push-on style connectors that are not difficult for even the most inexperienced DIYer. And they reduce leaks because of fewer connections.
How to size a PEX outlet?
Consider the demand on each outlet / how much water pressure desired at each outlet. Size the outgoing line of PEX coming out from the manifold accordingly. For instance, the faucets are all coming off ½” connections and PEX line. Hose bibbs are ¾” to keep up with manual watering or car washing water pressure demand.
How to determine the correct size of PEX manifold?
Compile a list of all the hot and cold lines required in your home. Next, consider future expansion and decide how many additional lines should be included to run a line of PEX to the ceiling and cap them off. These two answers will give you the proper size manifold.
How close to the middle of the house should a water heater be?
As close to the middle of the house as possible. The line from the water heater to the hot water manifold should be as short as possible too. If there is too much distance consider installing a second manifold and water heater.
Where should a manifold drain spigot be located?
The main difference is the location of the drainage spigots. They should be within the confines of the manifold cabinet. It is also ideal to have them at the bottom of each manifold. This location at the bottom ensures the spigot fully drains the entire manifold when opened.
Where is the drain spigot on a hot water manifold?
Do not forget to include a drain spigot at the bottom of both the hot and cold water manifolds.
Do you need to put hose bibs before salt water?
Is there an irrigation system in place that splits off before the manifold? You don’t want to pour salt water on your plants constantly. Depending on your answer, you may need to place the hose bibb PEX lines before the manifold.
Why are preassembled manifolds used?
Preassembled manufactured manifolds are the preferred choice by a lot of installers as it saves a lot of install time and money. It also help avoid unwanted leaks as they do not need to assemble manifolds on site by sweating parts to custom make a manifold.
What is a Pex manifold?
Pex Manifolds. Manifolds are used as a main distribution center usually from a larger supply line to multiple smaller sized PEX lines. Radiant Heating uses manifolds as a main central hub where the PEX lines begin and end for each loop.
Why use manifolds in plumbing?
Plumbing systems use manifolds to distribute hot or cold potable water from a central location to various fixture throughout the home. Using centrally and strategically located manifolds minimizes the total linear footage of pipes used and makes for a more efficient design of the plumbing system.
Why is sanding important?
It is very important to properly prepare the surfaces you wish to solder together. They need to be free of burrs, dirt and oil in order to have a tight fit. Sanding aids in this process combined with wiping off the sanded surfaces. The added benefit of sanding created tiny lines for your soldering flux to fill and then pull your solder into when heated. This creates greater surface area for the solder to adhere to and create and air/ water tight joint.
How far from the manifold should the main shut off be?
The main shutoff has to be 90 degrees from the manifold so there is clearance to turn.
Why was the cabinet dry fit in place?
The cabinet was dry fit in place to ensure all lines were long enough and the manifold was at a good height.
What does it mean when you attach a shut off to a manifold?
However, attaching the shutoff directly to the manifold means if anything goes wrong, you are guaranteed to touch the two major pieces of your whole house manifold.

What type of bit to use for spade?
We recommend using Forstner type bits. This will make for cleaner hole than a generic spade bit.
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.
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.
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.
