How to install Hep2O – Best practice for a trouble free installation

The Hep2O system is designed to be easy to install and effective, but to ensure you get the most out of it, we look at the steps you can take to ensure a safe, trouble free installation.

Hep2O pipe

Take care not to damage the pipe end. Whilst problems are rare, if the end that is inserted into the fitting is deeply scratched, there is a risk that a leak pathway can result. This is easy to avoid with a few simple precautions:

  • Take care how and where the pipe is stored.
  • Retain pipe in protective packaging until it’s used.
  • Never use an open bladed knife to remove the pipe packaging.
  • In the case of a coiled pipe, always use the pack cutter supplied (see Fig. 21 in Hep2O Installer Guide) to slit the packaging around the inside of the coil. This enables the pipe to be drawn from the inside, keeping it neat and protected.

  • Have a quick visual check if possible before inserting the pipe into the fitting.
  • The packaging then serves to contain the coiled pipe until the last metre (see Fig. 22 in Hep2O Installer Guide).

  • When threading pipe through holes in stone, brick or block walls always protect the pipe. You can use a a pipe sleeve or a small piece of foam pipe insulation to do this and to protect the pipe from rough surfaces.
  • Ensure exposed first fix pipe ends are protected from damage by using a temporary end protector. This also ensures no debris will enter the pipe (see Fig. 23 in Hep2O Installer Guide)

  • The pipe is very flexible but avoid kinking the pipe during installation.

Hep2O fittings

You shouldn’t have any problems with the fittings as unlike some other systems, they cannot be taken apart, but to ensure the best performance:

  • Store materials in a secure place, and keep them free from dust and dirt etc.
  • Keep fittings in their bags until ready for use.

Fittings are prelubricated and should be fine to re-use, however if it does require some lubrication, spray a little Hep2O HX200 Jointing Lubricant onto the O-ring (see Fig. 9 on page 11 in Hep2O Installer Guide). Never use flux or other oil based lubricants.

Handling and storage

Hep2O is an extremely tough and durable system. However, following the simple guidelines below will ensure its performance is not impaired by poor storage.

  • Straight lengths of Hep2O pipe should be stored flat or stacked vertically.
  • Coils may be laid on their side or edge.
  • Pipe and fittings, wherever possible, should be stored in their original packaging.
  • All Hep2O pipe and fittings should be protected from contact with petroleum and oil derivatives.
  • Avoid dragging the pipe along the ground or on other surfaces such as walls.

Following these simple precautions will ensure all your installations are trouble free and work perfectly.
