Any boat with or without that system has the possibility of flooding due to a broken hose or failure! That's why we keep up on the maintenance religiously. Make shure all hoses and clamps are secure and not cracked,ext.

Your boat should have 2 high volume bilge pumps so if you start to take on a lot of water, you would see both those pumps flowing water out the stern sides before getting flooded.
I manually test my pumps turn on every couple of trips.
