[NA] Dryer vent halp

1948 according to the interwebs. But I don't know if that's when the building went up or if that's when the house on the front area of the property went up. There might have been an 'improvement' along the way that added the other apartments to the lot.

I don't think people had forced-air tumble dryers in 1948. But I wouldn't know as that's my grandma's era.
 
That 2nd picture shows a lot. Now I think I understand.

What's the duct made of? Is it PVC?

To be honest, I have no idea. I'm going to have to pull the vent and look. From the inside, it looked like a dark dirt hole. It looked the same from the exhaust side too. It could be dark PVC... or it could be burrowed through the concrete. Here's a look down the hole from the vent side.

I'm thinking of elbowing it up and rigging up a PVC flapper at the top akin to the other commercial thingy... assuming I pull it apart and there's PVC in there. Hard to tell.
 
I just used the Google and looked up "under slab dryer vent". Turns out it's not uncommon, and does meet (or did meet) codes.

Possibly, that vent used to be higher above ground level and over the years grass and dirt built up around it.
 
So....... the good news is I got the old vent off. The bad news is the new vent doesn't fit. The worse news is the photo attached.

But the BETTER news is that I have no idea what I'm doing, so I have no way of knowing how screwed I am. =D

I'd start with a measuring tape, then go from there. ;-)

And not knowing how screwed you are always helps in home projects. Seriously.

"Oh, I think I'll fix the broken _____ this weekend..." always turns into loud cursing, beer, and realizing what a dumbass you were about an hour before the supply store closes on Sunday evening.
 
Amen. I measured the stupid pipe. Guess what it is... the OD is 100mm ish... Like 3 15/16. That corresponds to NO measurements in PVC. Which makes sense since it's black. Should've thought ABS... but I'm not sure that ABS fittings are that either... unless it's the hub measurement, in which case is it really a 3 inch pipe? I don't know.

You'll eventually hit the point where you've got the next size down in your hand in the store and a big tube of silicone caulk thinking, "eff it. This'll work..."

I've got the PVC fittings here. I'm so unbelievably tempted.

But guess what the orange store didn't have? 4 in PVC.

Well technically they had it. Wrapped. On a pallet. Outside. About 25 feet off the ground.
