I love my panels, and the crowd loves to see what graphic i might display on them next..
But while i love the moden age with panels and pixels.
I still love the glow of a incan light, and displays with moving animations (traditional displays)
so basicly your making the pump work harder by pushing fluid further?
I would suggest 1 pump in the snow machine for its internal tank,
an use mark's idea with the float switch to fill it from the big tub.
there just a basic pump, i have fixed mine 3 times now, (lights sand the grime off the inside parts)
but it hates being dry with no fluid, (thats what kills them)
I have replaced other peoples machines with different replacement pumps.. main thing to remember is prime the line or it wont pump..
