Air gaps for water conditoner

Thanks to everyone for the great forum! Sorry, my title should say water conditioner and I am unable to edit my pathetic spelling.

I was wondering if anyone can tell me if this is code compliant in general - splitting a laundry standpipe into 2 or 3 standpipes with wyes at the top of the standpipe sharing the same trap to drain a washing machine and 1-2 softeners.

If it is legal, then how many GPM can a 2" standpipe drain?

I don't see any issue with this plan.

Most installations create the air gap by just sticking the hose into the same pipe that the washer discharge goes into. This seems like a more reliable solution though.

The main requirement is to ensure there isn't an air seal there and that the pipe doesn't shoot itself out of the pipe with the force of the water.

As for GPM, you shouldn't have to worry about it - though I guess if you have 2 water conditioners and the laundry all running at once, it might become an issue. The good thing is most water conditioners will recharge at night, and you are likely doing laundry during the day/evening.
