Plumbing Question

[jlomon]

I've seen a bit of plumbing expertise thrown around here lately, so I thought I'd see if I can get some help. I want to replace a bidet with a pedestal sink in my master bathroom. What do I have to do with the drain in order to make this happen? I understand that the trap for the bidet is below floor level. Is it acceptable to just connect the drain for the pedestal sink to this existing trap? Or do I have to remove the under-floor trap and put in new drain pipes with an above floor trap?

Thanks,

Jonathan
