Pex pipe is a flexible type of pipe that is easier for amateur plumbers to use because of its simplicity. It is not rigid as more conventional types of pipe such as galvanized, copper, and CPVC so that it can change direction without the use of connection fittings.
Because of this quality, it's possible to run a supply line of Pex pipe directly from the main supply line of the home to each individual faucet and other plumbing components in the home. However, supply lines to individual components usually branch from the larger supply lines that are connected to the mainline. Requiring the use of reducing connections along the way.
You can eliminate the need for reducers and branch lines in Pex pipe installations through the use of Pex manifolds.
What is a Pex Manifold?
A Pex manifold is a sort of plumbing router. Water is fed into the manifold through an intake connection that accommodates a larger diameter supply line (3/4" diameter in most households) and dispersed through multiple smaller diameter connections (usually 1/2" diameter).
A larger manifold may be used at the location of the main supply line into the home to serve all of the plumbing components in the home, while a smaller manifold may take the place of smaller groupings of branch lines in individual areas such as bathrooms or kitchens.
Pex manifolds are also equipped with shutoffs for each individual outlet connection. Less expensive models use a special key that can be used to turn off the supply to an individual line in case of emergency while pricier models have actual valve handles that perform shutoff functions.
Pex connections are made through the use of metal clamps and a specialized clamping tool, eliminating the need for soldering, adhesives, or the brute strength required for galvanized steel pipe connections.
How are Pex Manifolds Installed?
Pex manifolds that supply an entire home are installed on a wall as close as possible to the main supply line into the home and the water heater. A 3/4" Pex line is then connected from the home's main supply line to the intake connection of the manifold. A 3/4" line is then connected from the manifold to the water heater and an additional 3/4" line from the water heater back to the manifold.
The manifold itself is divided to provide both hot and cold water connections to each component in the home that requires them. Smaller 1/2" lines are connected to these outlet connections and run directly to each component.
Of course, running individual supply lines to every component in the home requires a lot of Pex pipe winding its way throughout the home, so some installers choose to use the traditional branching method of supplying individual components from fewer but larger supply lines.
Smaller manifolds can connect to these larger lines at various locations and supply only a few components in each area, reducing the overall amount of Pex pipe needed for installation.
The type of manifold(s) required for a project will ultimately depend upon access to finished areas of the home as well as personal preference. Either way, Pex is an inexpensive and easier alternative to traditional piping choices.

After years of living in a home where the plumbing was less than ideal, I realized that we needed to do something about the problem once and for all. We started looking into different repairs, and a friend of ours mentioned a plumbing service that was known for their quick service and attention to detail. They came right out, started working on the problem, and before we knew it, our plumbing was perfect. I wanted to start a blog dedicated to plumbing so that you understand how to make things better. Check out this website for great information that you can use.
