What Is PEX Manifold? What Are The Benefits Of Using It?

A PEX manifold acts as a hub for distributing water across different zones around the house. It gives you control over each water line so that you can stop the water from flowing in a particular water line without affecting the others.

The structure of a PEX manifold resembles that of a breaker box. Inside a PEX manifold box, you’ll find separate chambers for the outflowing hot water and cold water lines.

The hot water manifold passes hot water from the water heater to the different fixtures throughout the house, whereas the cold water manifold passes cold water from the main water supply.

There are several benefits to installing a PEX manifold in the house.

  • PEX manifolds are flexible, so there’ll be a reduction in pressure drops.
  • Because hot water reaches faster to the faucet, there’ll be little energy waste.
  • Installation of PEX manifold reduces the labor cost of installing a water distribution system or floor heating system.
  • PEX manifolds eliminate the hassle of stopping the water flow across all lines.
  • PEX can withstand freezing temperatures up to 20 degrees Fahrenheit.
  • Since PEX is non-metallic, the manifolds won’t rust or corrode.
  • PEX manifolds don’t require plenty of fixtures.
  • PEX manifolds support water lines starting from as small as 3/8 inches.
  • PEX manifolds have color codes for hot and cold water lines.
  • PEX manifolds are easy to install.

Things To Consider While Buying PEX Manifold

Size

Before you start appraising the best PEX manifolds and decide which one is ideal, the first factor you’ll need to consider is the size.

PEX manifolds come in various sizes. It can be short, long, or thin to suit different spaces. If you plan on installing a larger manifold, you will need to have enough space in the room where you’ll be installing. Otherwise, all your efforts, as well as your money will go down the drain.

Instead of doing all the guesswork, we recommend you take proper measurements of the installation area. You need to measure the length, width, and height of the space and then look for a manifold that fits there perfectly.

Ports

Depending on how many lines you want to connect, you will need to choose a manifold having the corresponding number of ports.

Smaller PEX manifolds have 2, 3, or 4 ports, while larger ones have as many ports as 24. For installing PEX manifolds in small spaces, you will want to go for a fewer number of ports because there wouldn’t be enough space for accommodating more lines.

If you want to have hot and cold water lines, you will need to get a manifold having enough ports for differentiating the water lines.

Apart from the number of ports, you might also want to consider the size of the port. Most ports measure 1/2 inches, but you will also find ones having a 3/4-inch adapter to give you adjustability.

Inputs

PEX manifolds feature input ports from which water is collected and outlets that distribute water throughout different zones.

Input ports typically measure 1-inch in diameter to allow more water to flow through the outlets. Some PEX manifolds may also come with an extra outlet for draining or filling the port.

Having the additional port comes in handy at times when you need to check the distribution system for issues. It is also helpful for keeping filtered water going through the pipe.

Construction

The material your PEX manifold is constructed of is another crucial aspect you need to keep in mind.

PEX manifolds are typically made of copper, but you can also find ones made of stainless steel and plastic. Copper manifolds are commonly used because it is affordable and prevent rust from forming on the surface.

Another variation of a copper manifold is brass. Usually, it is termed ‘lead-free’, which makes it completely safe for potable water.

Stainless steel manifolds are a great option in terms of durability, but they are more expensive than copper. Despite that, such manifolds smoothly work for years without getting corroded and affecting the water quality.

On the other hand, plastic manifolds offer less durability than copper and stainless steel. It’s because they work within a specific range of pressure. Such manifolds are ideal for those who are always customizing the manifold system.

Depending on your personal preference, you need to choose the material accordingly.

Compatibility

PEX manifolds come in different sizes and contain a different number of ports. This wide range of options lets you decide which size and the number of ports will work great for your plumbing system.

Also, you’ll find most PEX manifolds to be pre-installed while others need manual installation. Before purchasing any PEX manifold, make sure it is compatible with your plumbing system.
