I used this for a water softener drain in the attic. I was a little nervous that it would spill over and cause water damage. After installing it on a 1.5 inch standpipe, and running ~5gpm through it, I can affirm that it doesn't leak or splash. It's a really study, quality product. I would recommend 100%

This product worked perfectly with my system. It provided the proper air gap to effectively seperate the drain / sewer system from my water supply, eliminating any chance of contamination. It also handles the water flow of my softener system without any splash during regeneration cycles.Great Product. Exactly what I was looking for.
