Let me clarify. A dryer vent terminal dedicated to plumbing venting, high up on gable wall w/o vented soffit. This is a new roof with no holes yet, heat is direct vent out the wall, why not plumbing?

all plumbing vents have to be above roofline...a dryer vent does not...it can come straight out from dryer location in ky. i dont think you can use dryer vent for any plumbing venting

Dry Vent Plumbing

A dryer vent is activated when positive pressure from the dryer is turned on. When not in use, the vent flapper stays closed. A plumbing vent allows sewer gas to vent and allows air to come into the system. If a flapper vent was in place, like a dryer vent, neither the sewer gas could escape nor the needed air could enter the system. What you are proposing is a definite no-no.

Most Plumbing codes I have worked under require the plumbing vent to exit through the roof. Piping must be the same material as those used throughout the rest of the house drainage system. Be advised that vent pipes carry potentially dangerous gases in them including Methane gas which is explosive.

Plumbing codes require it up thru the roof, but it will work just fine vented out the side wall with no flappers or obstuctions. It can be said that sewer gas can be toxic. Get real though, no one is going to stand there and suck on the pipe and inhale the fumes. As for explosive, get real, how many out houses blow up. This code rule is to prevent unpleasant odors from ever getting winded into the home, its not much of a safety issue.

Think of how bad the area would smell if your plumbing vent were enclosed in an attic. Whew! Send that smell out to nature where it is dealt with.
Also, the illness enclosed waste water vents can cause.
Keep it above the roof line and put a weather cap on it. It's only one more hole you have to cut.
Dryers can vent anywhere. In dry climates, they make good interior humidifiers if you don't mind the lint...

Plumbing vents most definitely have to be vented through the roof. Dryer vents don't.

DOES NOT have to penetrate the roof.
DOES have to extend above roof line 10" or more
Also has to be no less than 1/2 the size of your drain.
If your sewer line leaving the house is 4", then vent must be 2" or larger.

Because plumbing vents need to draft as well as let air in. Dryer vents and exhaust fans are forcing the air out.

the stink pipe needs to be exposed above your roofline, not necessarily through the roof, I have seen people bring them out throught the side of the house and upto an elbow an then out and around the eve, the wind blowing across the pipe creates a slight vaccum and pulls the sewer gases out of the pipes
