Basement Waterproofing - TrenchDrain Tying Into WaterGuard Drain

The TrenchDrain can be seen in front of the doorway in this photo, but ends just beyond the door frame. However, the TrenchDrain doesn't just stop there, but rather continues into the WaterGuard. This is important, especially because the WaterGuard has inspection ports so if there is a blockage, it can easily be located.
