faint gas smell near water heater
I'm familiar with gas leak odor, but what about a similar odor, yet not quite the same, near gas water heaters. Is there a residual odor from the combustion?
This is for a basement apt that has had this faint smell for years. Everybody gets used to it, though it's noticeable at first. We've even had med students live with it. Even so, I'd like to address it if there are any long-term issues related to folks breathing this stuff. Any thoughts? Thanks.
