I installed a AquaTrue under sink RO unit last week and having been using it since. During the install, I talked with customer service about not having many places to install the drain line above my p trap with the way the existing plumbing was ran. They assured me that having it an inch above the water line while also running a high loop would be the way to go and would not cause any issues.
I made the mistake of not researching further and had drilled into the pipe. Im now seeing other posts about RO drain lines and I’m worried about it’s placement. Is it going to cause any sanitary issues and I should figure out another solution (siphoning, etc)? Have we contaminated our system?
There is about a 1 inch air gap and about a 1/2 inch air gap when the sink is running. Water also shoots up that drain momentarily when the garbage disposal is ran. I know the height of the plumbing/p trap out of the wall is not ideal.
Any advice is welcome!
Edit: I thought an air gap was the space between the water line and the drain line. By saying air gap, I mean there is a 1” - 1/2” distance between the water line and drain line.
