I'm looking at moving the plumbing for my laundry to a new location on the main floor. The problem is, it's an exterior wall with no nearby vent stack. There is currently a utility sink nearby, but it's vented with an AAV (air admittance valve) but I'm not sure if code allows them in the area.
I'm looking for advice on options for venting the washer drain. There is a toilet and a floor drain about 12' away from where I'd like to put the washer drain, both have a vent accessible from the basement. I see a couple of options, but I'm not real confident that either is up to code.
1. Use an AAV on the washer drain. Does code allow this? Is it a bad idea to vent a washing machine this way?
2. Vent the washer drain to the toilet/floor drain vent in the basement. This would require dropping the vent stack down and then horizontally about 12'. I assume I'd at least need to bring the vent up to 6" above the washer drain before doing a 180 back down. Is going down with a vent stack a bad idea?
I hope this makes sense and someone can give me some good suggestions.
Thanks in advance
