Pipelife PEX Pipe Lengths

PEX pipe lengths offer the same versatile application as the coils, suitable for hot and cold water services, central heating, and underfloor heating systems. Their pre-cut lengths make them ideal for projects requiring specific, measured installations in both residential and commercial environments.

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.
