1. Should the sewer vent that extends out of my roof be pushing air out when nothing is draining? Everything in the house drains fine with no sucking water out of traps or gurgling.
2. I have a 3x3x1 1/2 t off my main drain for my washer. When I removed the washers hose, sewer gas and air blows right out. I know I need a trap there to keep sewer gas out but SHOULD the air be blowing like this?
3. My sewer vent use to run straight up through my roof. Someone added an addition to the house so the vent had to be re-routed and make some turns. It comes straight up, 90's over about 5 ft, 90's to the left a foot, 90's to the right about 3 ft, then that's where it 90's up through my roof. Is this acceptable?
4. At the bottom of my sewer drain there is a "T" which is under the concrete that goes out to my the town sewer. At one end of the "T", the opposite side where it runs off to the town sewer, is a plug. Well it seams whoever use to own the house always kept this open so if/when water leaks into the basement it has somewhere to drain. Well I want to keep this plugged because of the sewer gas that's escaping out. Should I put a pedestal sump pump there to pump the water that leaks into the basement outside? Or what can I do?

OK! What's open in your system that allows air to enter from below and exit out the vent? You almost have to be there to track it down. However, If the system's working OK then why worry?

Do you live on the side of a hill or in a windy area? That's not air blowing out it's sewer gas. Sewer gas is harmful to your families health and the methane content makes it explosive. Trap and vent the washer.

Yes! You may have as many bends in a vent stack as you wish as long as it slopes back to the fixture it's venting and there are no traps,( bells in the line) in the vent line.

I don't understand. But the first thing I would do is plug up the open line. Put a pedestal in where? This makes no sense at all, unless there's a basement sump where water collects and drains out into the sewer. But wait! If it were set up the way you describe the water would drain right past the tee on its way to the city sewer. What am I missing?? Regards, Tom
