Sewer smell inside on windy days
Asked Mar 2, 2008, 02:04 PM
My wife and I built our house 3 years ago in a high wind area (30-60 mph) and have had the wind suck our p-traps dry with every wind storm (Usually over 40 mph wind). I have done some research and found out that the vent pipes on the roof could be the culprit. I was wondering if there are check valves or similar on the market for purchase? And if in fact the ventpipes are supposed to only let air in, not out? What can I do to keep from having to refill the fixtures almost weekly?
Any help would be great
