Jeff (our plumber) was back today to work on the grease trap. After about an hour of putting gravel into the ditch and leveling it, the grease trap was finally in place. It is massive (3x2.5x2 feet):
A little after 3pm E! and I had to leave, we wanted to look at a ten burner cooking range that was for sale in Marlboro. The range looks good and we may get it, we just need to figure out how to get it here.
When we got back about two hours later, Jeff was gone, but he had finished the whole drainage around the grease trap. Unfortunately it was too dark already to take a good picture. I'll post one tomorrow.
