Question... So I simulated a power outage today (finally have some time) and well my sump would certainly overflow because of the back flow... So my question is..
For a siphon break, do I simply go into the overflow box, find the return, and drill a 3\16" hole into the PVC. From what I understand, when the water drains and gets to that point, it will break the siphon and water should stop flowing into the sump?
yes drill the hole slightly under the normal operating water level. The reason being is that you don't want to hear water shooting out that hole all of the time.
Then when the power goes out, the water will drop slightly until it hits that hole and breaks the siphon stopping the backflow.
