TubeNet

I came across something recently that caught my eye. I've always been told to take my rotors out before I washed a rotor tuba. But I saw something recently about a guy putting water through his tuba with the valves still inside it. Would it hurt the horn for me to put water inside of it with the rotors still inside? I've always been too scared to learn to take rotors apart and to try and do this myself.

I have learned to take them apart, just to scared to actually do it.

Can we "sticky" topics like this?
