Not that I can think of. Just remember that if you use the bulkheads that have to be glued in, they are made of ABS, not PVC. So you will have to use a transition glue if you are using PVC pipe. Threaded are nice because you can always reuse, I always leave at least one hub depth between fitting and Bulkhead so if I do remove it at some point I can always re-use it. Just my thoughts, HTH,
