Hey guys, sorry to post about this. I did a search and read some similar posts but just wanted to get a fresh opinion on my issue. I bought my house in August and there has always been a strange smell coming from the toilet in the downstairs bathroom. The tank water smells fine and looks very clean and I smelled around the base of the toilet and there is no smell. But if I smell the water in the bowl I get a strange odor, guess it could be a sewer smell. It was pretty bad for about a month (maybe in Dec/Jan), but has sort of tapered off. I also noticed that the level of water in the bowl tends to fluctuate. Sometimes it is full up to the indentation line you see on most toilets and then sometimes it seems to reduce in amount. Today for the heck of it I poured some extra water in there and the level definitely went down over time. Can someone just give me some ideas with basic explanations. I have to admit this is my first home and I am not exactly familiar with everything. Im learning things, but don't have a ton of background knowledge. Thanks everyone.
