Seal Information
The Premier Seal:
The Premier Seal for Aluminum ReRoof Drains!Portals Plus has developed a unique Mechanically Expandable Rubber Seal, “The Premier Seal”.The Drain is designed to replace existing drains in retrofit applications. All installation is conducted on the roof surface. The seal is activated by tightening the internal screws with the Premier Screwdriver. The Seal utilizes PVC flanges for increased strength and stainless steel screws to compress the EPDM rubber gasket. The compression of the seal expands it and makes contact into the existing piping of the pre-existing drain, therefore, preventing vertical movement and stopping water damage into the building. The Premier Seal exceeds SPRI and ANSI Retrofit Drains requirements.
Tape Seal:
A special precompressed modified asphalt impregnated expanding foam sealing tape automatically makes a permanent elastic watertight seal to the existing drain, eliminating water backup.
Rubber Seal:
The seal is instantaneous as the ReRoof Drain is inserted into the existing pipe! Years of research and testing have resulted in this unique seal that actually seals tighter as water pressure increases from backups. Hard to believe, but testing done by the engineering firm that designs the seals for America’s deep-diving nuclear submarines proves that it with-stands over a 50-feet pressure head of water, both with slow increases in pressure and sudden surges from 0 to 50-feet. The seal was found to resist leaking better than cast iron pipe!During the testing, the cast iron pipe developed porosity leakage from the 50-feet pressure head, but the seal held tight.
