I have a 30 x 35 ft (used to be alligator barn) Now it is a pole barn with 2 x 4 stud walls . It has a Cement floor that slopes from the middle down to both sides by 8 inches. It has some drains (pvc about 5 inches diameter) already in on the sides. It already has a 2 prong water spicket embedded in the cement.. Can I use the drains for anything or will I just have to crack up some of the cement for plumbing. I'm going to be putting sleepers in the floor to even it up, Is there anyway to put the plumbing in that area? Or will I have to crack it up ? Does anyone know what that would run to put in plumbing for 2 bathrooms and a kitchen that will be back to back? I hope I didn't confuse everyone.
Also it need a septic put in. Before it just drained into a large whole outside.
