Basement Waterproofing - Corner inspection port on WaterGuard

One of the newest innovations to the WaterGuard system is the corner inspection port. In years past there was just a 90 degree piece or solid pipe. Someone in Research and Development came up with the idea of adding an inspection port on the corner. This makes it so the pipe can be flushed in both directions if it gets dirt in it. What a great idea to improve an already fantastic basement waterproofing system.
