For some weird reason, during holiday time, kids tent to treat the toilet like it’s Public Enemy Number One. Or should that be Number Two? Anyway, children can do all sorts of horrible things to the humble lavatory which could block it, break it, or wreck it.
A flushing toilet can provide hours of holiday entertainment for bored youngsters. All that water, spinning and gurgling down the drain can have an almost hypnotic effect, and kids will flush, and flush, and flush to keep the show going. What a waste of water! And what a way to break the flushing system.
