Name: Rosie HILLSBOROUGH, NC (Zone 7b) If it sparkles - I'm there!
Holly..the weather would be a problem...but I think the outflow would get directed to a wide-ish form that sits right at the edge of the lip... A machine shop could fabricate from aluminum inexpensively ..the shape of a dust pan....return water hose coming through the "handle" then widening ...the returning water from the reservoir would never touch the piano but surely rhe elements would.
Don't squat with yer spurs on!
People try to turn back their "odometers." Not me. I want people to know 'why' I look this way. I've traveled a long way and some of the roads weren't paved
