convert 1 1/2 outlet to 3 inch sewer hose?
I have come to the conclusion that i will need a 2nd grey tank in addition to the primary gray and black tank due to the location of my kitchen sink. I have the tank, and the perfect spot to mount it. the question is how can i use the same 3" sewer hose when this 2nd gray tank only has a 1 1/2" threaded outlet. Would just putting a couple bushings/reducers on the outlet to get up to 3" make sense? is there something i'm missing?
