Check the picture out. My plumber said that this is an air break and will work just as good if not better than an air gap because it won't splash out. He said this is code and ok for my application. Please confirm.
I have a whole house sediment and chlorine filter that backwashes so it needed to go to the same drain. I had him run two separate drain lines to this vent stack because the filter manufacturer said they couldn't use the same drain line. Any issues with this either?
They both drain and don't leak, so I guess that is good.
