Claim 8
Dependent Claim
60 words
A roughing in plumbing unit comprising a drain piping system and a water supply piping system adapted to be incorporated in a wall structure, said systems being preassembled and tied together in regions where the systems cross one another to provide a unitized rigid assembly adapted for transporting and installation at the erection site for incorporation in a wall structure.
Claim 9
Dependent Claim
