I see the overflow tube going to the second sump.It just seems very risky.
Yea the risk is within the u-tube itself. If it ever stops its siphon for whatever reason, then I will get a small flood of the water that is in the second half of sump 2. But the tube keeps its siphon even if all pumps are shut off. Both ends of the tube are always in water as the levels are always the same. Pretty much the same risk as the standard overflow box i have on the DT. Its been a good week so far with no issues...
I'll let you know when i wake up one day and hear water splash with each footstep i take :D
