FAQs

What is MDPE?

MDPE stands for Medium-Density Polyethylene. It's a type of plastic pipe commonly used for water distribution, gas, and other fluid applications due to its flexibility, durability, and resistance to corrosion.

What does PN10 mean?

PN10 indicates that the fittings are rated to withstand a maximum operating pressure of 10 bars, which is approximately 145 psi. This is suitable for many standard water supply and irrigation applications.

Do I need special tools to install these fittings?

No, these MDPE fittings use compression connections that are designed for hand-tightening, with a final snug turn using a standard wrench. No specialized plumbing tools are required.

Is PTFE tape included in the kit?

No, the kit does not include PTFE tape. It is recommended to purchase PTFE tape separately for use on the BSP threads of the lever valve to ensure a watertight seal.

Can this kit be used for drinking water?

While MDPE is often used for water supply, ensure that all components, including the specific type of MDPE used and the valve, are certified for potable water applications in your region. This guide focuses on the mechanical aspects of the fittings.

What is the thread size of the lever valve?

The lever valve has a ¾” BSP (British Standard Pipe) thread, with both male and female connections.

How do I connect the 25mm flange to a 20mm pipe?

The kit includes a 25mm wall flange and a 20mm tee. You would connect the 25mm MDPE pipe to the wall flange, and a separate 20mm MDPE pipe to the tee fitting. If you need to adapt between sizes, you would require a specific reducer fitting.

Troubleshooting

Leak at connection point

Ensure the MDPE pipe is fully inserted into the fitting and the compression nut is tightened sufficiently. Check for any damage to the pipe or fitting. Re-apply PTFE tape to BSP threads if applicable and re-tighten the valve.

Fitting won't tighten properly

Verify that you are using the correct size MDPE pipe for the fitting. Ensure there are no obstructions or damage to the threads.

Lever valve is stiff or difficult to turn

Ensure the valve is properly installed and there is no debris inside. If the issue persists, the valve may require replacement.

Low water pressure after installation

Check that the lever valve is fully open and that there are no kinks or blockages in the MDPE piping. Ensure all fittings are correctly installed and not restricting flow.

Pros and Cons

Pros

  • Easy installation with compression fittings, no special tools required.
  • Durable construction from MDPE and brass for long service life.
  • High resistance to corrosion and chemicals.
  • PN10 rating ensures suitability for moderate pressure applications.
  • Versatile for water supply, irrigation, and industrial uses.

Cons

  • PTFE tape is not included and must be purchased separately.
  • Compression fittings may require careful tightening to ensure a perfect seal.
  • Tee fitting is 20mm, while the flange is 25mm – ensure correct sizing for your application.
  • Lever valve is BSPM – F thread, verify compatibility with existing fittings.

Setup, Compatibility & Care

Setup:

  1. Ensure the MDPE pipe is clean and free from debris.
  2. Slide any necessary compression nuts and rings onto the MDPE pipe.
  3. Insert the pipe end firmly into the appropriate fitting.
  4. Tighten the compression nuts securely by hand, then use a wrench for a final snug turn. Avoid over-tightening.
  5. For the wall flange, ensure the mounting surface is flat and clean before securing.
  6. For the lever valve, ensure the BSP threads are clean and use PTFE tape (purchased separately) on male threads for a good seal.

Compatibility:

  • Designed for use with 25mm MDPE pipe for the wall flange and 20mm MDPE pipe for the tee. Ensure your pipe conforms to these sizes.
  • The lever valve features ¾” BSP male and female threads, suitable for standard BSP fittings.

Care:

  • MDPE fittings are low-maintenance. Periodically check connections for tightness.
  • The brass lever valve may benefit from occasional cleaning to ensure smooth operation. Wipe with a damp cloth. Avoid abrasive cleaners.
