Filter backwash to floor drain

[Powerless]

Hello,

Is it up 2 code to drain filter to floor drain.
I believe that drain is connected to sanitary system not to storm water or sump.

( I will get plumber to snake it )

I do have access to main stuck but no vent and I don’t want to use those little no vent things.

Thank you

You can, but you should elevate the output above the grate, commonly illustrated by tying the line to a brick.

The flow can be high on a backwashing filter... 5 or 10 gpm is not uncommon, and it can be higher. You would usually put an elbow in the end to direct the flow to the grate. Expect splashing.
