A curious seasonal event

[HouseManager]

Hello,

I am house manager of a fraternity house. This is simply a yearly elected position mostly concerned with keeping the house clean and doesn't suggest I'm even slightly handy. Which is why I've come here.

We have this curious problem. Every Spring around April, our second floor urinals begin overflowing with poop water. It has become a notorious yearly event.

Our house is three floors. The two upper floors have each have a bathroom with two urinals and three toilets. The third floor bathroom is located directly above the second floor bathroom and flushing the urinals on the third floor is usually the spark which starts the flooding.

Recently, brothers have heard the urinals gurgling on the second floor.

Clearly our entire plumbing system needs some sort of involved renovation. But I'm looking in the short term to prevent the flood.

Is there any way we might prevent this before it happens?

Just confirming I understand the problem..

When the third floor urinals are flushed, it causes "poop water" to overflow out of the second floor urinals/toilets? Does it also overflow the first floor urinals/toilets, or just the second floor? What about the third floor urinals/toilets?

Thanks for the reply,

The first floor doesn't have any urinals, just one toilet. The third floor urinals do not overflow, but when flushed cause the second floor urinals to gurgle or speed the flow when the urinals are overflowing.

Typically only the urinals overflow, the toilets have never overflowed before.
