When installing a PEX plumbing or radiant heating system, the PEX manifold plays a central role in managing flow, pressure, and system efficiency. Whether you’re a professional contractor or a system designer, choosing the right PEX manifold can save you time, reduce leaks, and enhance overall performance.

In this guide, we’ll cover the key features to look for in a PEX manifold, the different types available, and how to select the right model for your project—especially if you’re sourcing from trusted manufacturers like ifanpro.

🚿 What Is a PEX Manifold?

A PEX manifold is a central control hub that distributes water from a main supply line to multiple outlets. It acts like a traffic control system for your water supply, ensuring balanced flow, pressure management, and individual line shut-off.

PEX manifolds are widely used in:

• Residential plumbing
• Radiant floor heating
• Hydronic heating systems
• Multi-zone water supply systems

✅ 1. Material Quality: Brass vs. Polymer

PEX manifolds are typically made from:

• Brass: High strength, corrosion resistance, long service life
• Polymer (plastic): Lightweight, cost-effective, corrosion-proof

Brass manifolds are preferred for durability and high-pressure environments, while polymer manifolds are a great option for low to medium-pressure residential systems.

✔️ ifanpro offers both brass and polymer PEX manifolds—certified to ISO/ASTM standards, suitable for global markets.

🔧 2. Number of Outlets (Ports)

Choose the correct number of ports depending on how many zones or fixtures your system will supply. Common options include:

• 2-port, 3-port, 4-port, 6-port, 8-port, 10-port
• Expandable models with add-on kits

More ports = more flexible system design. For larger homes or radiant heating, 8–12 port manifolds are common.

🧰 3. Integrated Shut-Off Valves

Valves give you individual control over each water line—essential for:

• Isolating leaks
• Performing maintenance
• Balancing system pressure

Look for manifolds with pre-installed ball valves or removable valve cartridges.

👉 ifanpro’s manifold products come with optional valve kits for maximum control and convenience.

💧 4. Flow Meters and Balancing Controls

Flow meters allow you to:

• Visually monitor water flow per circuit
• Balance each loop in radiant systems

This is critical for hydronic heating to ensure each room receives the correct amount of heated water. Consider manifolds with:

• Built-in flow meters
• Adjustable balancing valves

🧩 5. Compatibility with Pipe Sizes

Your manifold should match the PEX pipe sizes you’re using—commonly:

• 1/2 inch
• 3/4 inch
• 1 inch

Some manifolds come with multi-size adapters or universal connections. Always check for crimp, clamp, push-fit, or compression type compatibility.

🏗️ 6. Mounting & Installation Options

A good PEX manifold should be:

• Easy to mount (wall brackets, cabinet-ready, panel systems)
• Clearly labeled for each zone
• Leak-proof and pressure-tested

ifanpro’s manifolds are engineered for fast installation, with optional pre-assembled mounting kits to save time on the job site.

🌍 7. Compliance & Certifications

If you’re working on regulated plumbing systems, be sure the manifold complies with:

• NSF, UPC, or WRAS certifications
• ISO 21003 / ASTM F877 / EN 12165 standards

These ensure safe use for potable water and heating.
