I've never head any problem with Presta valve tubes and my washer adapter in a Schrader valve hole..

I sometimes come across tight-fitting Shraeder pump heads. Some pump heads require force so I will put some spit on the threads for a while until the rubber grommet breaks in. I use a twisting action when removing the pump head which makes that part easy.
