Yes BUT not an outside wall
The one going out of the wall or floor goes to the septic. The one going up is the vent that should go out the roof.
I need this answer as well. Anyone?
Exactly as it says, a wall that is constructed to take the weight of a second floor, or roof. -Not just a flimsy separation wall.
If you have professionally installed siding and roofing this should not be a problem. If you are having this problem the most likely place for water to seep into the wall cavity would be from the roof. Water can find it's way through almost anything and sometimes these kinds of leaks can be very difficult to locate. Have a professional roofer check the roof over to see if there is anything obvious. They will check the valleys, areas around the chimney, around plumbing vent pipes and roof vents etc. It could be a simple fix or it could mean replacing the roofing materials.Good luck!
No you cannot wet vent an ejector pump and no you cannot vent through a side wall. It must go through the roof.
Yes BUT not an outside wall
The vent for the drain is in the wall. Where the drain goes in, it T's with the water going down and the vent going through the roof. With a double sink, one side is the vent for the other. As long as the water isn't pulling against a vacuum, it will drain.
a direct vent water heater is more fuel efficient (cost's less to operate). aside from that there isn't much difference, aside from not needing a double wall flue through the roof on a standard gas water heater.
YES you can! you can even use a dryer vent to the outside.
The type require is vent is required for a cooktop vented down and out an exterior wall (for the outside wall itself) I am installing an electric cooktop, with a pop-up downward vent that pulls steam and such through pipes in the floor.
The alternative to a plumbing roof vent is an AAV. This is an Air Admittance Valve, a simple spring loaded ABS fitting that serves exactly the same function as a roof vent, except that it does not penetrate the roofing. I used 4 of these while re-plumbing my mobile home, three under countertops and one in the wall behind toilet. I'm very happy with their performance and even happier at having less holes in the roof.
bird blocks and ridge vent
Check the code for your area. Most I have seen go through the ceiling.
You also have to use the code for your city or your county. Most county and city codes are the same saying that they need to be roof vented. No, that would defeat the purpose of a vent being that there needs to be air pressure to keep the sewer gas down. Sure you can, If you want the waste to drip from the vent too the ground, but who cares the Chinese do it so why cant you??? A waste drain vent allows the air to flow so that the drain works properly. It has to meet a calculation that I do not Know, BUT a licensed Plumber will know this calculation. I believe you are asking because this is an unusual situation. Just remember if it does not meet the calculation, you will have nothing but trouble with the drainage. please consult with a GOOD plumber.
No, directly vents through to outside wall of building.
It could be you have a leak in your roof or a broken pipe inside a wall that is causing this. I'd check out the roof first (usually "goop" will do the trick for a quick fix) and if it isn't the roof then bring a professional in to see where the leak is.
