I'm not sure but from the last dump I just did, the macerator seemed faster. I would let it run for 45 seconds, stop it for 15 and then run it again at the same intervals. For some reason it seemed to drain the last bit faster than the 3"....
In any event, it works very well and clean up is a breeze. After all of the back washing, I will then hook the water hose up to the dump hose for even extra clean out although it is pretty damn clean otherwise.
Very please overall. Honestly, sitting in line waiting to dump is just a buzz kill.
