Basement Drain Mains™
Controls water seepage with out dumping!
Basement Drain Mains™ use two co-extruded Rubber Seals along the bottom of the system to reduce Dumping exterior water under the Basement Floor. Instead of dumping Hydrostatic Pressure under the basement floor... Drain Mains trap Hydrostatic Pressure with Two Rubber Seals and use the Hydrostatic Pressure to drive water to the Sump Pump system.

3 Rigid Gussets create fluid chambers. As water levels rise into these chambers a Water Level Effect takes over and drives High water towards Low water (The Sump Pump) as water always is self leveling. Gussets are continues to filter debris from floating up into this natural drive mechanism.
