There appears to be no standing water in the drain I want to use. I believe the original plans were to install a trap above the slab for the sink. I do not want to raise the shower up to accommodate the trap. Vent stack is roughed in to a bathroom above, on main floor. House is hooked into a septic system. I don't believe I can hook the shower drain directly to the out flow without a trap. Are there any options other than busting up the concrete in order to put a trap in? Thanks!
