Introduction

PPR (Polypropylene Random Copolymer) plumbing systems have become a top choice for water supply projects due to their leak-proof connections, durability, and resistance to corrosion. But proper installation is key to performance and longevity. Whether you’re a DIY enthusiast, a plumber, or a project manager, this step-by-step guide will walk you through the correct process of installing a PPR plumbing system.

Tools and Materials Needed

Before installation, prepare the following tools and materials:

Tools:

• Pipe cutter or rotary pipe cutter
• Pipe fusion welding machine (with heating bush and adapters)
• Marker or pencil
• Tape measure
• Pipe support brackets

Materials:

• PPR pipes (PN10, PN16, PN20 depending on use)
• PPR fittings (elbows, tees, unions, reducers, etc.)
• End caps, valves, and transition fittings (if needed)

🔧 Tip: For the best results, use pipes and fittings from the same manufacturer, such as those from ifanpro Pipeline.

Step 1: Plan Your Piping Layout

Start by analyzing your building’s layout to determine the most efficient piping route.

• Mark connection points (outlets, valves, water sources)
• Calculate the total pipe length
• Minimize unnecessary bends to reduce water pressure loss

Step 2: Cut the PPR Pipes

Using a pipe cutter, cut the pipe to the required length. Ensure the cut is:

• Straight and clean
• Free from burrs or rough edges

🛠️ Pro Tip: Do not use a hacksaw—it may leave uneven edges and reduce fusion quality.

Step 3: Heat the Pipe and Fitting

1. Turn on the PPR welding machine and set it to the correct temperature (usually around 260°C).
2. Allow it to heat for 3–5 minutes.
3. Insert the pipe and fitting into the heating bush for the recommended time (e.g., 5–6 seconds for 20mm pipe).

⚠️ Caution: Do not twist or overheat, as it may deform the parts and weaken the joint.

Step 4: Join the Pipe and Fitting

1. Immediately after heating, push the pipe and fitting together without twisting.
2. Hold them in place for several seconds (cooling time varies by size).
3. Let the joint cool completely before moving or applying pressure.

🔄 Repeat this process for each joint. Proper alignment is essential.

Step 5: Secure the Pipes with Clamps or Brackets

• Install pipe supports every 50–100 cm for horizontal runs
• For vertical pipes, use brackets to prevent sagging
• Avoid tight bends or over-tensioning during installation

Step 6: Test the System

After completing the installation:

1. Seal all outlets with caps or valves.
2. Fill the system with water and pressurize it (typically 1.5x working pressure).
3. Monitor for 30–60 minutes to check for leaks or pressure drops.

✅ If everything holds, your installation is successful and ready for long-term use.

Common Installation Mistakes to Avoid

• Overheating or underheating the pipe
• Twisting during fusion
• Using incompatible fittings from other brands
• Skipping pressure testing
• Installing pipes without proper alignment or support
