Smoke coming out vent pipes

This morning after finishing a small modified torch repair I turn around to see every pipe on the roof bellowing smoke. scared the crap out of me. I'm thinking the house is going up in flames. I look around to discover every house in the neighborhood pluming pipe bellowing smoke. The city testing system for potential problems. WHEW! B) :) :) B) Deep Down In Florida Where The Sun Shines Damn Near Every Day

I brought the story back to the Very Lovely Mrs. Ciak at the humble abode. She asked " You didn't stick your noise over that pipe and sniff , did you? I had to confess "I Did" It was odorless. B) :) :) B) Deep Down In Florida Where The Sun Shines Damn Near Every Day

BOOM. Good one OS!

If you watch that video of the guy farting, you can see the similarities between these two topics.

The text was to small to deal with. I live in Pinellas County. 3 tabs are still allowed here. B) :) :) B) Deep Down In Florida Where The Sun Shines Damn Near Every Day

Chuck looks like that owner could use a new 3 tab shingle roof covering, its looks bad but probably the HO sez it don't leak The age old story of the Florida homeowner all waiting for another wind or hail storm lol Up in ypur territory do you need the Miami Dade approved 3 tab shingles, thats a big joke unless you use a SBS shingle and special nailing pattern along with the the dry in the rating will still be under 100 mph lol The mfg strike thru the back door lol

The reason for the p trap is to prevent odors from the sewage backing up in to the house also to keep rodents and other vermin out of the household however sometimes certain item get through, perhaps one of the items is smoke Strange

Every house in the neighborhood smoke rolling out of the vents. Apparently the County was pumping smoke into the sewer system. Odd. It sure is annoying the text is so small. Any way of fixing this problem ? B) :) :) B) Deep Down In Florida Where the Sun Shines Damn Near Every Day[size=5][/size]

Chuck what kind of system are they using usually the vent pipes are attached to a plumbing p trap and nothing should go through the water in the trap sure sounds weird to me.
