Can I use this fitting for gas lines?

No, the Polyplumb system is not suitable for gas transportation.

How do I remove the fitting?

Polyplumb fittings are demountable but can only be disassembled.

What is the grab ring?

The high-performance stainless steel grab ring inside the fitting ensures superb joint integrity and a secure connection by gripping the pipe.

Where can I use this fitting?

It is suitable for hot and cold water supply and heating applications, including underfloor heating.

What is the benefit of using a pipe stiffener?

A pipe stiffener prevents the plastic pipe from collapsing, ensuring a secure seal and preventing leaks.

Troubleshooting

Fitting leaks after installation

Ensure the pipe is fully inserted into the fitting and that the grab ring is properly engaged. Check the pipe end for damage and ensure it's cut squarely. If using plastic pipe, verify that a pipe stiffener has been used.

Difficulty inserting the pipe

Ensure the pipe end is clean and free of burrs. If necessary, use a pipe lubricant. Check for any damage to the fitting or pipe.

Setup, Compatibility & Care

  1. Preparation: Ensure the pipe ends are clean, cut squarely, and free of burrs. Use a pipe cutter for best results.
  2. Insertion: Push the pipe firmly into the fitting until it reaches the stop. A proper connection is made when the pipe is fully inserted and the grab ring secures it.
  3. Pipe Stiffeners: When using with plastic pipe, always insert a Polypipe metal or plastic pipe stiffener into the pipe end before inserting it into the fitting. This prevents the pipe from collapsing and ensures a secure seal.
  4. Compatibility: This coupler is compatible with Polypipe grey polybutylene pipe and copper pipe. Always use the correct size pipe for a 15mm connection.
  5. Care: No special maintenance is required, but regularly inspect the connections for any signs of leaks. Avoid excessive force or stress on the fittings during installation and use.
