My sump drains to the sewer so any extra water is just gone lol

That seems dangerous. I don't know if you realize the tunze will only pump for max 5-10 mins then cut off and go into a safety mode as a backup. 10 mins of pumping with the pump is not all that much water. I would re consider your plans here.
