How to fix laundry tiling with water not running to drain?

Mattinterior

I have just had  my Laundry screeded and tiled. When I pore water through the bottom of cabinet directly behind drain (plumbing not connected yet ) the water flows under the cabinet but away from the drain not towards  it!!

My understanding the purpose of screeding is to allow a fall to direct water towards the drain not away.

I appreciate any feedback..Thanks

Hi @Mattinterior,

Thank you for your post and welcome to the Bunnings Workshop community.

It is not necessarily a requirement for a laundry floor to be graded towards a floor waste. It is possible that this waste is not there to act as drainage, but rather an inspection point, or a trap for containing gases from waste water.

Unfortunately, I do not have access to the Australian Standards that outline the building requirements relating to this. 

As the work was only carried out recently, I would suggest speaking with the installer about what you've found and whether this waste's intended purpose is to drain surface water.

Let me know if you have any further questions.
