Pex Manifold Buying Guide


Most of the ports on a Pex manifold are outlets. These outlets ensure a more centralized distribution from a primary source to the rest of the plumbing system. Manifolds still come with various input ports.

Such ports usually have a diameter of up to 1-inch, a width allows the device to pass enough water into the system. Some manifolds come with an additional 1-inch outlet port. This outlet can work as a filling port or for draining the plumbing system.

The additional port is vital when you want to test the distribution within the system for any problems. Having extra output ports comes in handy when you have filtered water running through your piping.

If you want to install a hot/cold water system, a manifold with two inputs comes highly recommended. Such a device offers you a two for one alternative.


The size of the devices is another essential consideration. You might have minimal space to work with when installing the system. When you have the wrong product, the whole process may end in frustration or failure.

Proper measurements of the installation space, i.e., length, width, and height, can make this process easier. Such estimations will allow you to find a product that fits into a limited space.

Luckily, most of the manifolds in the market come with a thin overall profile. Such a slim profile can fit between two walls or inside insulation panelling. Some designs can either be short or long as well.

Before committing to your purchase, please ensure that it will fit into the desired area when you are setting it up. Otherwise, you might have a very disappointing experience.


The number of loops is another vital consideration to make when purchasing a Pex manifold. You will get approximately 2 to 24 loops on the manifolds in the market. Therefore, it is crucial to check how many Pex connections you need, to choose an appropriate product.

Aside from coming with a different number of loops, Pex manifolds also feature hot or cold-water loops. Such products fit the technical specifications of various plumbing systems. You should check to ensure maximum compatibility.


Pex manifold feature three kinds of material in their production. These materials include; copper, stainless steel, and plastic or polymer-based alternatives.

The most commonly used material is copper. This metal comes as an excellent choice for buyers looking for simplicity, efficiency, and affordability. Copper is highly resistant to rust and coating from water sediments. Safer Lead-free varieties are also available and are marketed as “brass.”

Stainless steel alternatives are more durable and reliable when compared to other Pex manifold. However, they come at a higher price. Such devices can last for decades with minimal issues and less corrosion, which enhances the overall quality and safety of the water that passes through your plumbing.

You can also find polymer or plastic-based alternative in the market. Such devices work within specific pressure limits and are less durable when compared to stainless steel or copper alternatives. Plastic-made Pex manifolds are neither expensive nor cheap.

Plastic/polymer-based manifolds work best for users who continually customize their plumbing systems.


As mentioned, manifolds come in a variety of sizes and featured ports. The variation of these features allows for various levels of compatibility. Looking at the number of ports and sizes can guide you into purchasing a product that can easily interface with your pre-existing plumbing system.

Some Pex manifolds come pre-installed, while others do not. The diameter of your piping can also influence your preference for a particular product over another one. This incompatibility may create a lot of undue hassle when choosing a product and may force you to buy additional high-pressure attachment joints.

Some products like VIVO PEX manifold offer an all-in-one system. When you opt for such a product, you get the advantage of not having to set it up. All you need to do is check the compatibility before committing to a purchase.


Different manufacturers and retailers offer varying types of warranties on their products. A warranty is a sign of the producer’s confidence in their product. Many products with extended warranties last for decades with few issues in between.

Most of the famous brands offer a limited lifetime warranty. Such brands are ideal because they come with service guarantees on the product and parts. When shopping for the perfect product, please consider the warranty offered as it is an indication of the life service you will get.

Final Words
