Splashes of napaak on the clothes

Respected Mufti saheb

I have some questions. Please answer as soon as possible.

1) I put wet semen stained clothes on the shower and it also touched the wall attached to the shower.so my question is if I wash the shower and attached wall with a pipe then there will be chances of it splahing water back on me as well as on the pipe.should I consider that water naapak?I mean whether me and the pipe both will become naapak?if yes thn how to wash them?
