Retrofit Trap

The WaterMark-certified retrofit self-sealing device is shown alongside the HP cutaway so its location and function within the tundish are immediately clear.

Reduced Installed Cost

By removing the requirement for a separate trap access panel and associated finishing, the HP system has the potential to reduce both component and installation costs.

Common Issues With Conventional Inwall Tundish Installations

Real project photographs illustrate two recurring problems the HP design was developed to address: leakage into the wall cavity where the overflow arrangement is not sealed, and external fixing points being covered or compromised during wall finishing.
