Could you expand on this one for me?
This is only my second hurricane season and I haven't heard that I need to protect the toilet! l-}
It was a joke. If the wind is coming up through your toilets, you're in a heap of trouble.
In some floodprone areas, flooding can cause sewage from sanitary sewer lines to back up into houses through drain pipes. These backups not only cause damage that is difficult to repair but also create health hazards.
A good way to protect your house from sewage backups is to install backflow valves, which are designed to block drain pipes temporarily and prevent flow into the house.
