Dog, why the 2 90’s from the p-trap to the tank? Couldn’t you eliminate them?

Also, fine tune your drops to the hopper before you glue everything,  run some water down each drain, watch where the water comes out of the pipe, meaning you are only dumping small amounts of water down the pipe, therefore it will want to flow from the low, or bottom of the pipe to the hopper,,,,, looks like your going to have a wet floor as of now..
The clocer to dead center, the better….

Good call on the test water. The pic may look like it might blow all over the floor, but I assure you it’s a bad angle… lol. I made sure there is ample space and everything lines up as much as it can to the center of that drain. 🙂

I’m probably going to glue it all tomorrow after the run.

The 90’s had to be put in b/c I couldn’t do a straight run, it would have ran across the edge of the base, so I had to bend it to get it to center under the sinks.  Small trailer = gally kitchen, but that’s not really a bad thing b/c everything is within reach. 

Dog….You could eliminate the 90° elbows by rotating the hopper 45° right where it sits and use a 45° elbow into the tank. Just a thought.
