Sewer smell from toilet

[Joe]

There is an odor that is coming from the toilet. This usually occurs first thing in the morning (after toilet hasnt been flushed for several hours). Smell goes away after flushing, but will come back the next day.

TIA for any help.

[we will presume you have nice smelling tap water.] first change the $1 wax seal. examine the floor flange under the wax and fix it if needed. there are some modern non-wax seals available now. see:

Tried one of these; only to find it would not work. The box does not mention that if you have a sharp turn just below the flange the device will not work....back to the old wax ring.
