I am expanding an existing bathroom. The current bathroom has a wet vent (2") with a single sink, a shower and a Toilet. The new layout will have dual sinks, tub, shower, and toilet. I am moving the toilet location. Single story house on concrete slab. Located in Florida IPC code. Main line is 3". Lines to shower and tub are 2". The location I am moving the toilet to happens to run almost directly over the main horizontal drain line. I am wondering if I can tie this in with a Wye and a 45 directly up to the toilet? Will I have any issues with the toilet siphoning the tub or shower traps? Drawings attached
