Kenny, it's not for the back-flow .... It's to stop air getting into the system. The sump can handle the small amount of this tank
The problem was air getting back into the circuit, from that tank being so hi above the sump, and bubbling out when the pump re-starts.
It made a huge mess with all the air coming out of the lines, overflowing the sump and splashing everywhere.
I'm running switches and so on for 'sleeping' security, but they aren't ready yet.
That will be for a later post
You'll see some more 'too much' if I do what I'm thinking
