I have got Bach Strads with and without 3rd slide spit dump valves; Bach have offered this as an option on Strads for years. If it was going to be a bad affect why would they offer it?? But why it is not a standard feature - well I don't know.

In any case I do believe they need to be placed in the correct position, and I do get moisture in all my Strads.
