How to add a sump without drilling or syphon drain.

[mdb_talon]

Basically exactly what I was saying. The water will flow down from the sump into the DT, so you just have to set your water levels and heights to account for that fact.

No..actually nothing like you were saying. You stated that you cant have the sump much higher than the DT because the water levels "will equalize".... None of that makes sense or is relevant in a properly configured system.

Water will never go lower than the overflow drain
