Lower Condensation Potential

Drain-Guard prevents damage due to condensation, because it possesses superior thermal properties compared to cast iron. The outer secondary DWV pipe safely contains any possible condensation that may occur on the exterior of the primary DWV pipe, protecting the surrounding area from condensation damage. In addition, storm water lines may not require insulation.

Improved Flow

The larger inside diameter and lower surface roughness factors of Drain-Guard, compared to those of cast iron DWV systems, ensure a noticeably higher flow capacity – Drain-Guard exhibits improved performance with low flow water closets.
