Things to Know Before Buying A PEX Manifold

If you’re really sure of getting the best PEX manifold for your residential or business water distribution system – then you’ll want to be equipped with the highest amount of info about them.

Here, we explain the major factors that will make a difference between a bad and a decent manifold:


There are 3 kinds of materials that you can get for PEX manifolds. The first and most common is copper. It is an affordable alternative for those who want simplicity above anything else. Some copper options are entirely lead-free, especially the ones marketed as brass, so they are very safe to use.

Then, you’ll find stainless steel. This is a way more durable and reliable alternative. But of course, steel is far more expensive. A stainless steel manifold can last decades without problems, creating less corrosion and increasing the overall safety of the water that passes through.

And finally, you’ll find plastic alternatives or polymers. These are not bad choices and can be either expensive or cheap.

However, they only work with specific pressure limits so they can be less durable than copper and stainless steel. We only recommend these for those who need to customize their manifold system continually.


Size is essential for your system. When you’re installing the manifold, you’ll probably have to work in a small space – so if you don’t have the right product, it may eventually backfire.

We recommend getting something that fits inside the place where you are installing it. For that, make sure to make all the measurements in width, height, and length depending on what you’re looking for.

Most manifolds are thin enough to fit between two walls, but they can be long or short and sometimes a little high depending on the design.

So, before buying a manifold, always try to be completely assured that it fits inside the place you’re setting it up. Otherwise, you are set for a very disappointing experience.


Regarding ports or loops, you’ll have to consider both size and quantity. Some irrigation systems demand up to 8 ports or more. A water distribution system for houses may demand up to 12 ports. And radiant systems can be from 4 to 12 ports accordingly. They all differ exponentially, so be sure of what you need.

But the number of loops is not enough – you should consider the size. For example, most PEX ports are 1/2-inches, but you may also find 3/4-inches ports depending on the design of the piece.

Some manifolds come with a 1/2-inches port by factory and a 3/4-inches adapter so you can make it work in your system.

It is always better to get something that offers more ports than you really need so you can be prepared in case you need an additional port. But also consider if you’ll need hot and cold water ports differentiated, so make sure to get a complete-enough manifold.


As you should know, most ports on a manifold are outlets. This means they are made to distribute water from the primary source. However, manifolds also come with inputs.

These are often 1-inch in diameter, so they let enough water go in and distribute accordingly. But some models not only come with a 1-inch inlet but also a 1-inch outlet that works as draining or filling port.

If you are often testing the distribution system against issues or to filtrate water, then having an additional 1-inch output can be pretty helpful.

We recommend going for manifolds with two inputs so you can have a better chance to install hot/cold water systems. Of course, that’s your choice still – if you don’t need two manifolds then get only one.

Benefits Of Using a PEX Manifold

After reading our PEX manifold reviews, you’ll probably want something to ensure that you’re getting a product that’s worth having. If so, then let us tell you all about the advantages of getting one:

  • Stand All Kinds of Temperature

A PEX manifold can stand even the hottest or coldest temperatures. You can make it work with radiant heating systems or with heating elements close to water outlets without problems. Similarly, they can stand freezing temperatures without breaking or splitting, which is a big plus.

Apart from that, PEX manifolds can last years without corroding or rusting due to temperature-related issues. And that’s a huge advantage when compared to other types of manifolds.

  • Turn Off Water Flow Easily

Most manifolds have a unique valve design that you can easily turn on and off depending on your needs. So, if there’s a line that needs closing due to repairs, customization, or for any other reason – then a manifold with individual valves will be hugely useful.

You can manage multiple lines from a single point without needing several valves all around the house. This is a massive advantage in big homes and large commercial buildings. By merely closing one line to make a fix, the rest of the lines can work without any problem.

  • Convenient Choice for Commercial Buildings

Even though this mostly works for the largest PEX manifolds out there, you can always install one in commercial buildings and get a lot of positive results.

If you’re installing a water-distribution or a radiant-heat system, then using a PEX manifold system may be your best idea. They come with up to 12 ports or loops that you can hook up to different lines and manage water from it.

Some models come with up to 36 different ports for an even more convenient experience. In commercial edifications, this is a practical advantage that no one should overlook.

  • Manifolds Fit any Kind of Plumbing System

Even though they work with PEX piping effectively, most of these manifolds work with all kinds of tubes and sizes. You can use 1/2-inches lines made of copper, or 3/4-inches inches tubing with PVC, sometimes even 3/8-inches supply stainless steel pipes if needed.

This helps users in old or new houses to install one of these with their water distribution system without having to reinstall or remodel the whole plumbing.

  • Highly Convenient Color Coding

A PEX manifold often comes with different colors for hot and cold lines. This is a giant plus for people who want a straightforward installation process.

Some manifolds without this color grading may become a headache to use. Luckily, PEX manifolds do it effectively to make the whole process a piece of cake.

  • Straightforward Installation

When you get a PEX manifold, the set-up is probably the most advantageous thing of all. You won’t have to spend days installing the piece inside your house. It just takes a few screws inside the wall or anchor point, and that’s it.

Some models even come with their own rings, clamps, and fittings so you can install them in a matter of minutes. And of course, the design allows a simple set-up of all the lines going all around. You won’t need ample space to set it up even if you pick a large manifold model.

Frequently Asked Questions

You may think you already know everything about PEX manifolds, but very likely you don’t. That’s why we bring a few some common doubts from users and the corresponding answer to each. Want to learn about them? Here they are:

Q: Do I really need a PEX manifold at home?

A: Not necessarily, as long as you use a reliable and efficient distribution system at home. But if you want the most practicality possible for redistributing water all around your house, a PEX manifold is your best bet.

Q: How much does a PEX manifold last?

A: Normally, one of these pieces can last several decades. From 30 to 60 years is the typical lifespan of a PEX manifold. However, with proper maintenance and fixings when needed, you can get up to 100 years. But it is still recommended to change the manifold every 50 years for safety reasons.

Q: Are PEX manifolds ideal for heating systems?

A: Yes, especially radiant heating systems for floors. PEX manifolds offer the chance to connect multiple lines to the same product, which is a considerable advantage compared to other types of connectors and distribution systems.

Q: Can I use a PEX manifold underground?

A: No, while it is possible to do so – we recommend not to. Not only will the brass or stainless steel corrode this way, but it is also not the ideal installation for PEX or other types of plastic lines.

Q: If the manifold is made of copper or steel, can I connect PEX tubing?

A: Yes, you can connect any type of line as long as you have the right adapter or connection diameter. Most PEX manifolds come with 1/2 or 3/4 inches connections. If the lines fit these measurements, you’ll probably have the ideal option for your home.

Q: Is the installation of a PEX manifold costly?

A: No. In fact, installing one of these manifolds is less expensive than many other water distribution systems you can get. It is often faster to install and also takes less effort overall.

Q: May I use a PEX manifold for compressed air?

A: No, you shouldn’t use any of these products for compressed air. It wouldn’t work and may end up damaging the piece. Especially the ones with pressure gauges and meters may break with compressed air.

Q: Is it be safe to use a PEX manifold in outdoors?

A: Some models are entirely safe to use in an outdoor installation. But you should be sure it is useful before choosing. Most manifolds are just for interiors that are well-protected – so make sure you have the right product if you want to make an outdoor setup.
