does this stop actual water back up or just the fumes?

I think it is meant to only block fumes but probably would at least limit the amount of fluid coming back.

There is also a filter screen in the accessories of the floor drain, which can stop the hair.

I know this is gonna sound silly but i have no experience in this type of field where do i measure so that i am getting accurate size? need help

You only need to measure the inner diameter of your drain pipe, and see if you can place our floor drain with the width of the inner diameter. Then you can use a tape measure to measure the depth of the pipe and then select the appropriate size of the floor drain. You can see the picture of our products

99% of households apply?? Most shower drains around here are 2” id and I see this says 1.55 to 1.77 “hole”... Is this a mistake? or is there a 2”?

Hello, this product is aimed at small water pipes, the size is less than 2 '', between 1.55-1.77''
