yup Donna isn't it funny what we often learn the hard way!

My lesson on making sure I drain the grey tank before it overflows came to me in the middle of one night when I went to use the bathroom only to get my feet wet! Good news is it is only grey water and it is a
fiberglass floor so its easy to clean and no real harm done.
Keeping a plug in place is always a good idea as it helps to keep dirt and twigs from shoes from getting into the pump. I keep a small floor mat in the bathroom at all times to help with that as well.
