Replaced old septic tank, now there’s stale poop smell
We had to replace our septic system from 1951 with a new system - regulations for a nitrogen reducing system. So they crushed our old cement one in place and installed the new nitrogen reducing system with new drain field.
Now there’s a faint lingering stale poop smell around where the system is. It’s not all the time or in your face - it’s like you walked into a space someone just farted. What makes it an issue, it’s right next to our ac unit…so I think there’s some old septic farts that are coming in when our ac kick on.
Is this normal for there to be stale poop smell from a replaced septic system? Is there anything I can do? And no, I will not blame the fart smell on the dog.
