This is from another post I started but hopefully someone can help me figure out a solution to this issue with my overflow not working:
Ok so I decided to build an overflow for this but am running into a few problems. Once i prime the system I have to cap the vent to keep in order to keep it going. So I'm guessing it's running by siphoning. It also only restarts if I do a short break in water flow. So needless to say, as it stands this is going to cause my living room to flood. Does anyone have advice on how I can fix this to work correctly and not have a flooding potential.
So just found out that if it drains to fast from my display (homer bucket) to the sump (tub) the draining stalls and causes flooding as well..
