PPRC pipes, short for Polypropylene Random Copolymer pipes, are widely used in Pakistan’s plumbing systems due to their excellent strength, chemical resistance, and ability to withstand both hot and cold water. Whether used in residential homes, commercial buildings, or industrial systems, PPRC pipes offer long-lasting performance and safety.
However, the benefits of these pipes can only be fully achieved when they are installed properly. Incorrect installation may lead to leaks, misalignment, or reduced lifespan. This blog serves as a step-by-step guide for beginners, DIY enthusiasts, and professionals on how to correctly install PPRC pipes and fittings for durable and leak-proof plumbing.
Tools & Materials Needed
Before starting the installation, gather the following tools and materials to ensure a smooth process.
Tools Required
Pipe cutter
PPRC welding machine
Tape measure
Marker
Spirit level
Chamfering tool (optional)
Materials Required
PPRC pipes (in desired lengths)
PPRC fittings (elbows, tees, reducers, sockets, etc.)
Pipe clamps or supports
Safety Precautions Before Starting
Work in a clean and organized area to avoid accidents
Wear safety gloves and goggles to protect your hands and eyes
Ensure the main water supply is turned off before cutting or joining any pipes
Keep the welding machine away from flammable materials
Use properly grounded electrical connections for the welding machine
Preparing for Installation
Use a tape measure and marker to measure and mark the pipe lengths accurately
Cut the pipe squarely using a pipe cutter for clean, even edges
Remove any burrs or sharp edges to ensure a smooth joint
Dry-fit and lay out the pipes and fittings in the correct order before heating
Welding & Jointing Process
Heating
Plug in the PPRC welding machine and set the temperature to approximately 260°C
Wait for the indicator light to confirm the tool is ready for use
Fusing
Simultaneously insert the pipe and the fitting into their respective welding sockets
Hold the parts in the socket for about 5–7 seconds (longer for larger diameter pipes)
Remove both pieces and quickly align them into the final position without twisting
Let the joint cool naturally without applying force or adjusting its direction
Installing the Pipe System
Place the welded pipe assembly into the desired position
Use pipe clamps or supports to secure the pipes firmly along the wall or ceiling
Maintain a proper slope where necessary (e.g., for drainage lines)
Avoid creating sharp bends or applying excess stress on the pipes
Use a spirit level to ensure proper alignment across the system
Pressure Testing & Final Checks
Allow the joints to cool completely (usually at least 30 minutes)
Seal both ends of the piping system and connect a pressure gauge
Conduct pressure testing at 10–15 bar to check for leaks
Monitor the system for any drop in pressure or visible leakage
If the test is successful, the water supply can now be turned on for use
Common Mistakes to Avoid
Overheating or underheating during the fusion process
Misaligning the pipe and fitting before the joint cools
Applying physical force or moving the pipe before cooling is complete
Not supporting pipes adequately with clamps, leading to sagging
Using incompatible fittings or low-quality pipes
Maintenance Tips After Installation
If used outdoors, protect pipes from sunlight using proper insulation
Avoid hanging heavy items or equipment directly on the pipework
Periodically check joints for any signs of wear or leakage
Clean filters, strainers, or inline valves regularly if part of the system
