I have a Fijibox overflow that I am planning to assembling with all of the other plumbing glued together except the overflow itself. I can't find any information on the material that the bulkheads are made of so I an glue the plumbing in place. I have also read that people just dry fit their PVC and don't have issues with leaks. Looking for some guidance whether I use ABS to PVC cement, PVC to PVC cement or dry fit and ruin my carpets...
