Make Your Overflow Pipe Powerful and Balance Your Sump Filtration

Please see the picture below.
Simply attached this device to your overflow end pipe that goes to the sump.
It will create a powerful siphon making your sump filtration balance. Does not need to calculate what motor pump to be used or
make the pipe bigger in order to get more water out fro your overflow.
Not good in explaining. I hope the picture helps.
Two video. 1 drill a hole in the tank to make overflow pipe. 2 is a overflow pipe without drilling a hole in the tank.

Hope this help
