We have an NPS aerating septic tank and one basement bedroom smells of chlorine every time the septic tank is in an aeration cycle. The septic tank doesn't have a chlorine post-treatment system.
There's drain piping in the bedroom (going up one outside wall to the first floor bathroom) but no floor drains or fixtures. There may be drain lines from the basement bathroom and laundry room under the bedroom slab but I'm not certain about this. There is also supply plumbing including a PRV. All of the above-slab plumbing is exposed and there are no visible leaks.
The smell is strongest near the interior bedroom door rather than near the drain piping for the 1st floor bathroom.
During prolonged power outages (~4h+), the bedroom does smell of hydrogen sulfide / traditional bad-eggs sewage. Most of the time, however, the bedroom has no particular smell except when the septic plant is aerating.
The DWV piping in the rest of the house is sketchy (both the downstairs bath and lav drain very slowly; there is no visible trap on the laundry drain) but the smell issue is confined to the one bedroom.
1. Does this look like a sub-slab DWV leak or am I barking up the wrong tree?
2. How the heck can I find a plumber who can solve this? I know sub-slab leaks take specialists but I'm in a rural area (Howe Sound corridor north of Vancouver) and getting anyone to show up is a challenge.
Any guidance would be greatly appreciated.
