Today I came home to find 75 % of my 275 gal tote had overflowed .
This is not the fisrt time this has happened- this would be the third time .
Overview of system: I have a flood and drain system 275 gal tote 600 gph pump to beds with about 100 sf of grow space .
My return tank is a 40 gal brute trash can with a 1000 gph sump pump I purchased at a garden warehouse .
The pump has stopped working three times leading to overflowing .
Does anyone know of a reliable sump pump or any ideas that would help?
