Sewer smell coming from slop sink
This is my current set up. Washer drains into slop sink, slop sink is draining into ejector pit. My slop sink lately has been giving off serious ejector pit stink. We’ve been here for 4 years and this hasn’t been an issue until now.
I understand it probably has something to do with the p-trap losing it’s prime but I’m trying to figure out why it’s an issue now. It never goes dry because we’re doing laundry once every few days. Any advice on how to eliminate the smell?
