Yes. I have. I was brought up in a time (1950s) when washing machines were too small to take bedclothes and there were no laundrettes - and could not afford the laundry every week. I can remember using the posser in a tub of sheets and using the ringer with another tub to catch the water.

In fact, our family's first washing machine was a Hoover - just a washer - no spin-dryer - but a wringer on the top! (It lasted YEARS!)

It was not plumbed in and was filled with a bucket of hot water and that tube was how we emptied it into the same bucket when finished (thumb over the end - or else!!)
All this new technology available today often takes you away from how we used to do it in the 'Old Days'!
