are low profile traps compliant in queensland? we have only 140mm above concrete slab and do not want to have to break the slab to re pipe the bathroom. there was a flexible plumdinger in place when we removed the crap spa bath previous owners had installed.https://www.swanonline.com.au/DWV-Fl...ap-100mmx-50mm ( i think this one would need a reducer to receive the bath/shower wastes)https://www.amazon.com.au/Profile-Ac.../dp/B09ZQT5R1R
