Is there a maximum horizontal distance that a trap can be from the drain?
I have a mid-60s bi-level house that has a cantilever on the upper section. As shown in diagram #1, the original shower base extended over the cantilever and the trap was right under it. I gutted the bathroom and replaced all the old copper drains with PVC. The new shower base will be in the same location, but I need to use a trap with a clean out. The clean out would not be accessible if it is placed in the cantilever. If I do the set up as in diagram #2, the trap would be approximately 15" from the drain. The trap would still serve it's purpose (I think), but I need clarification on the distance as if it would cause any problems that I can't think of. Thanks
