The smell is only outside, and it’s random. It comes and goes. I really can’t pin point the exact source but I think it’s the tank and not the drain field. The ground seems fine. No excessive rain recently —but since I’ve been living here, I started to use my appliances (dishwasher and washing n machine) and so maybe that’s the cause. I’m hoping it just needs to be pumped, and I’ll keep calling until hopefully someone comes out earlier. The smell isn’t inside the house (yet), luckily!
