Occasional odor in bathroom when vent fan is on
Posted by R.W. on January 13, 19101 at 18:14:36:
There's sometimes an odor in our bathroom after the vent fan has been running for awhile usually at bath time (to prevent moisture buildup). After the fan is off for a short time, the odor goes away. Wondering if the odor could be coming from the sink drain? We have a septic system that's well maintained (pumped recently and regularly).
If the odor is coming from the drain, is there anything we can do to stop it other than not turn on the fan?
Or could the odor be coming from around the base of the toilet?
