i'm buiding a new bathroom on the first floor. do i need to have a separate vent teed off from the waste line of this toilet if there is already a vent at a septic tank. i'm afraid if i don't have a separate vent line from the one at the septic tank, then it won't flush properly because this bathroom is on the first floor.
