Hi experts,
I have a question regarding my outdoor floor level, hopefully anyone with plumbing knowledge can help. Thanks in advance.
I have two drainage inspect point(don’t know what exactly they are) outside my laundry. Pls check my attached photos.
I’m going to tile this area, but I don’t know if the floor level can higher than that two point or must be same or below that two point. One looks like discharge point, I don’t know.


It’s much appreciated for your help.
