PEX Pipe Coils

PEX pipe serves as a flexible and efficient plumbing option, ideal for both hot and cold water supply, as well as central and underfloor heating systems. It's designed to meet the demands of both residential and commercial settings, providing effective water distribution and enhancing heating system efficiency.

• Crosslinked Polyethylene (PEX) Construction: PEX pipe is made from crosslinked polyethylene, enhancing their long-term stability against high temperatures and pressures. This crosslinking also imparts resistance to slow crack growth and reduced creep at fitting connections.
• 100% Recyclable: Emphasizing environmental responsibility, these pipes are fully recyclable, aligning with sustainable practices.
• BS7291-Class S and WRAS Approvals: These approvals guarantee the quality and reliability of PEX pipes, ensuring they meet stringent standards.
• 50-Year Guarantee: A testament to their durability and quality, these pipes come with an unbeatable 50-year guarantee.
• EVOH Barrier Layer: Incorporates an oxygen diffusion barrier, making the pipe virtually impervious to gases and protecting against UV damage.
• Flexibility and Rigidity: PEX pipes are uniquely designed to be both flexible for easy installation and rigid enough to minimize sagging, maintaining a neat appearance.
• Time and Cost-Effective Installation: Designed for easy and quick installation, these pipes can significantly reduce labour costs and time.
• Compatibility: These pipes are compatible with BS 7291 Pushfit and standard Brass Compression Fittings and Manifolds.

• Material: Crosslinked High-Density Polyethylene (PEX)
• Available Sizes: 15mm, 22mm, 28mm
• Approvals: BS7291-Class S, WRAS, BSI Kitemark
• Temperature Range: Up to 92°C at 3 bar, with short-term overload up to 114°C
• Pressure Range: Up to 12 bar for cold water, 6 bar for hot water systems

1. Planning: Outline the pipe route, avoiding sharp bends and extreme environments.
2. Cutting: Measure and cut the pipe with a PEX cutter for a straight edge.
3. Pipe Inserts: If using plastic fittings, insert a pipe stiffener into the pipe end to maintain integrity and prevent collapse.
4. Fitting Insertion: For push-fit fittings, push into the pipe until secure. For crimp or clamp fittings, position and secure using the appropriate tool.
5. Routing: Carefully route the pipe, avoiding kinks and using pipe clips to secure it at regular intervals.
6. Fixture Connection: Connect the pipe to the fixtures, ensuring all connections are tight.
7. Leak Testing: Turn on the water supply gradually, checking for leaks and addressing any immediately.
8. Insulation: Insulate the pipe in areas prone to freezing.
9. Compliance Check: Ensure the installation adheres to local building and plumbing codes.

PEX (Crosslinked Polyethylene) and PB (Polybutylene) pipes are both popular for plumbing applications, but they have key differences:

1. Material Composition: PEX is crosslinked polyethylene, providing enhanced strength and thermal properties. PB is polybutylene, a form of plastic less resistant to high temperatures and pressures compared to PEX.
2. Durability: PEX pipes offer greater long-term stability and resistance to stress cracking, making them more suitable for high-temperature applications and environments with potential external damage.
3. Flexibility: Both PEX and PB are flexible, but PEX typically offers superior rigidity, helping to minimize sagging while still allowing easy routing through difficult spaces.
4. Temperature Resistance: PEX pipes can handle higher temperatures and pressures, making them ideal for hot water systems and central heating. PB pipes are more suited to lower temperature applications.
5. Longevity: The crosslinking in PEX provides enhanced durability and a longer lifespan, especially in demanding conditions.
6. Environmental Impact: PEX is 100% recyclable, promoting environmental sustainability, whereas recycling options for PB may be more limited.
7. Compatibility with Fittings: While both types are compatible with various fitting systems, PEX's compatibility with BS7291 specified systems and its ability to maintain integrity under compressive loads make it a more versatile choice in diverse plumbing scenarios.
8. Certification and Approvals: PEX often comes with more rigorous certifications and approvals (such as BS7291-Class S and WRAS) due to its enhanced properties, ensuring quality and reliability.

Utilizing push-fit fittings is an efficient and user-friendly method to connect copper pipe to PEX pipe. Here's a streamlined guide:

1. Prepare the Pipes:
   Copper Pipe: Cut the copper pipe to the required length. Ensure the cut is clean and the end is deburred.
   PEX Pipe: Use a PEX cutter to make a straight cut on the PEX pipe.
2. Select Suitable Push-Fit Fittings: Choose push-fit fittings that are compatible with both copper and PEX pipes.
3. Install the Fitting on the Copper Pipe: Clean the end of the copper pipe to remove any debris. Push the copper pipe into the push-fit fitting until it reaches the stop. Ensure it's fully seated for a secure connection.
4. Connect the PEX Pipe: Insert the end of the PEX pipe into the other side of the push-fit fitting, pushing until it hits the stop point.
5. Secure the Connection: Check that both the copper and PEX pipes are firmly attached to the fitting with no gaps.
6. Leak Testing: Slowly turn on the water supply and inspect the connection for leaks. If any are found, ensure the pipes are fully inserted into the fitting.
7. Final Inspection: Ensure that the connection is stable and there is no movement at the joint. The fitting should be snug on both the copper and PEX pipes.
