For about a year, my shower on a third floor is giving an on off gas smell sometimes after a shower and particularly in the morning not long after the sun rises enough to hit our roof.
I usually run some water into my p-trap and the smell goes away after a few minutes. There is a tub right next to the shower stall which we have tried keeping the plug in or out with minimal effect.
On advice of a plumbet, I climbed up on the roof and ran a hose with water to see if the water would backup anywhere in the 3 floors attached to thar plumbing stack. 2 kitchens and that upper floor bathroom showed no problems. He suggested running a 50 foot snake down the roof vent to see if some animal had been dropping stuff down the roof vent. I saw and felt a 45-90 degree elbow in the attick from on the roof with an 8 foot stick.
Particularly when the sun is hot the smell seems to come quicker in the morning. When its not a warm day the smell barely comes.
