In response to Re: Septic systems
The rainy weather floods your septic disposal field and then fills your main line under the floor, probably close to ground level. The toilet pipe is usually lower than that so the toilet is "air bound" and cannot flush. The sinks and everthing else are connected differently so they will work even with a flooded main line.

: I have a septic system that works fine during the dry months. However, during the rainy season I have a toilet that will not flush. What is strange is that the sink and tub in that bathroom does drain. What could it be?
