What is the maximum vertical length of indirect waste piping?

Explanation:
Indirect waste piping relies on a vented path to prevent siphonage and to keep gravity drainage functioning properly. Keeping the vertical rise from the fixture outlet to the indirect waste receptor within a limited distance ensures there is still effective venting and that trap seals aren’t pulled when water discharges. If the rise were greater, venting wouldn’t keep up, and the trap could siphon or drainage could slow or back up. Therefore, the maximum vertical length allowed is fifteen feet.
