System Information

Secure installation

You get a secure fit every time thanks to Wavin’s In4Sure security feature. Once the connection is in place, you twist the pipe or fitting and feel the “rumble” – signaling a perfect fit.

Flexible and versatile

Hep₂O pipe comes off the coil straight but is highly flexible for fast and easy installation. The system works great with copper and plastic so is ideal for new build and refurbishment projects. A wide range of fittings are available to accommodate any plumbing job.
