Product Information

Full details

This kit is for DIY enthusiasts and professionals needing a reliable connection for water supply or irrigation systems. Its key benefit is providing a secure, leak-free junction with versatile component integration. A key consideration is that PTFE tape is not included and must be purchased separately. The kit includes a 25mm MDPE wall flange, a 3/4" BSP in-line valve, and a 3/4" BSP to 1/2" barb joiner, offering durability, chemical resistance, and ease of installation.

FAQs

What is MDPE?

MDPE stands for Medium-Density Polyethylene, a type of plastic pipe commonly used for water supply and distribution due to its flexibility, durability, and resistance to chemicals.

Do I need special tools to install this kit?

No, this kit is designed for easy installation. Standard tools for tightening compression nuts and potentially a pipe cutter are usually sufficient. No specialized crimping or welding tools are required.

What is a BSP fitting?

BSP stands for British Standard Pipe. It's a set of common industrial pipe threads used for connecting pipes and fittings. This kit uses 3/4" BSP threads.

Is this kit suitable for potable water?

While MDPE is often used for potable water, the suitability of the entire kit for drinking water depends on specific local regulations and certifications. Always verify product compliance for potable water applications if intended for human consumption.

Can I connect a different size irrigation pipe to the joiner?

The joiner is specifically designed for 1/2" irrigation pipe. Connecting different sizes may result in leaks or a poor connection. Adaptors would be required for other pipe sizes.

How do I ensure a leak-free seal?

Ensure all compression fittings are tightened securely and evenly. For BSP threaded connections, use PTFE tape (purchased separately) on the male threads to create a watertight seal. Ensure barb connections are pushed fully onto the pipe.

What is the maximum pressure rating?

The MDPE fittings in this kit are rated PN10, which means they are designed to withstand a maximum operating pressure of 10 bar (approximately 145 psi).

Troubleshooting

Leak at the wall flange connection

Ensure the MDPE pipe is fully inserted and the compression nut is tightened evenly. Check the mounting surface for flatness and consider using sealant if necessary. Ensure PTFE tape is used on any threaded connections to the flange.

Leak at the in-line valve or joiner

Ensure PTFE tape is applied to the male BSP threads before connecting. Tighten connections securely but avoid over-tightening, which can damage threads. Check the barb connection to ensure the irrigation pipe is fully seated.

Low water flow

Confirm the in-line valve is fully open. Check the irrigation pipe for kinks or blockages. Ensure the MDPE pipe is not restricted. Verify that the system pressure is adequate.

In-line valve is difficult to turn

Ensure no debris is obstructing the valve mechanism. If the valve is new, a few cycles of turning may loosen it. Do not force the handle.

Pros and Cons

Pros

  • Provides a complete solution for connecting MDPE pipes to surfaces and integrating flow control.
  • Durable and weather-resistant plastic construction ensures long-term reliability.
  • Easy to install with compression fittings and a simple barb connection, requiring no specialized tools.
  • Resistant to chemicals and corrosion, suitable for various environmental conditions.
  • The in-line valve offers smooth and precise flow regulation.
  • Cost-effective compared to metal alternatives and complex plumbing solutions.

Cons

  • PTFE tape is not included and must be purchased separately for installation.
  • Primarily designed for 25mm MDPE pipe and 1/2" irrigation pipe; not suitable for other sizes without adaptors.
  • Plastic construction may be less suitable for extremely high-temperature applications compared to metal.
  • Requires basic plumbing knowledge for optimal installation and leak prevention.

Setup, Compatibility & Care

Setup:

  1. Prepare the Connection Point: Ensure the surface where the wall flange will be mounted is clean and flat.
  2. Attach the Wall Flange: Secure the 25mm MDPE wall flange to the mounting surface using appropriate screws (not included).
  3. Connect MDPE Pipe: Insert the 25mm MDPE pipe into the wall flange's compression fitting. Tighten the compression nut securely to create a leak-free seal. *Note: PTFE tape may be required for threaded connections to the wall flange if not directly connecting pipe.*.
  4. Install the In-Line Valve: Screw the 3/4" BSP Male end of the valve into the corresponding thread on the wall flange. Use PTFE tape (purchased separately) on the threads for a secure, leak-free seal. Ensure the valve is oriented correctly for flow direction.
  5. Attach the Barb Joiner: Connect the 3/4" BSP Female end of the joiner to the other side of the in-line valve. Apply PTFE tape if necessary.
  6. Connect Irrigation Pipe: Push the 1/2" irrigation pipe firmly onto the barb end of the joiner. Ensure it is seated fully for a secure grip.

Compatibility:

  • Pipe Size: Designed for 25mm MDPE pipe and 1/2" (approx. 12-13mm internal diameter) irrigation tubing.
  • Thread Size: Utilizes 3/4" BSP fittings for valve and joiner connections.
  • Pressure: Suitable for systems operating up to 10 bar (145 psi).

Care:

  • Periodically check connections for leaks.
  • Clean the exterior of the components with a damp cloth as needed.
  • Avoid using abrasive cleaners or solvents that could damage the plastic.
