System Information

What’s next?

Hep2O plumbing systems are part of an extensive range of Wavin products for domestic and commercial environments, including Hep2O underfloor heating. Please view our short product and installation videos of Hep2O on our You Tube Channel.

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.


Fittings can be easily adjusted with the HepKey demounting system. Simply clip the HepKey over the fitting to depress the collar and release the fitting. This system prevents tampering or accidental demounting and ensures your installation is totally secure.

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.
