I am currently trying to install an air admittance vent (studor) to a drain line in my basement to relieve sunctioning of my kitchen and bathroom sink. My sump pump is tied into the drain line and when it kicks on its creating a vacuum effect sucking the water out of the traps. I was told to install a studor valve above the traps in both sinks to relieve this. However there is not enough pipe coming up through the floor to tie the valve into.
My question is this: Is it possible to tie the studor vent into the horizontal drain line that runs in the basement versus hooking it up to the vertical drain line that goes to the sink? I thought maybe using a T connector and then placing the studor vent on top and then tying into the horizontal drain line might fix the problem. Was wondering if I'm on the right track or way off. Could use some help. Thanks
