Extended Product Information

FAQs

Is this set suitable for drinking water?

Yes, this product is WRAS approved, meaning it meets the requirements for use in potable water supply systems.

Do I need special tools to install this?

No, this is a mechanical compression set that can be installed using standard hand tools.

Can I use this with copper pipes?

No, this reducing set is specifically designed for MDPE (Medium Density Polyethylene) water pipes.

What is the specific reduction ratio for this part?

This set reduces from a 50mm pipe fitting down to accommodate a 25mm pipe.

Can these be reused?

While the components are durable, it is best practice to inspect the O-rings for wear and replace them if they appear damaged or deformed before reusing the fitting.

Troubleshooting

Leakage at the joint after installation

Ensure the pipe is cut squarely and fully inserted past the O-ring. Tighten the compression nut further.

Difficulty inserting the pipe into the fitting

Check for burrs on the pipe end and ensure the pipe is clean and free of debris.

Pros and Cons

Pros

  • Easy installation without special tools
  • Space-efficient design fits inside existing fittings
  • Certified for potable water applications
  • Allows for flexible system design changes

Cons

  • Specific to 50mm to 25mm size reduction
  • Requires proper seating to ensure a watertight seal
  • Not intended for non-MDPE pipe materials

Setup, Compatibility & Care

To install, ensure the pipe end is cut square and deburred to prevent damage to the fitting seals. Slide the compression nut and the necessary components of the reducing set onto the 25mm pipe. Insert the pipe firmly into the 50mm fitting body until it reaches the stop point. Tighten the nut by hand until it is firm, then use a wrench to provide the final tightening as specified by the fitting manufacturer. For care, avoid using abrasive cleaners or petroleum-based lubricants on the rubber seals, as these can degrade the material over time. Regularly inspect joints for signs of moisture if the system has been subjected to ground movement.
