We have a septic system. We remodeled a bathroom this summer and also had our septic tank cleaned out. Why is there still a sewer smell in the commode sometimes but not always and what can be done about it?

How low is the water in the bowl?

If it is to low, then gas can escape through pipe just above the waterline.

I am more inclined to go with a faulty wax seal rather then a bad trap seal in the bowl. Regards, Tom
