Re: Mystery Leak

Being that you are in Miami, I would certainly call the building inspector's office and ask what the code is for down there. Being that you are in hurricane territory and down there they are a PITA about it, you will want to do it right and get the proper permits if needed.

We sold a home in Miramar and they went so far as to make us get a permit and inspection for a window that was installed BEFORE we even bought the house.

Our homes are semi-detached.

The fact that the builders went out of their way to route the exhaust into the attic makes me paranoid about rerouting to the neighbors yard.

I need to research carefully the HOA and code implications in my area before I start drilling holes in the side of my garage.

The other homes must be set up the same way and have the venting in the attic. How are those homeowners handling this problem ? If other homeowners are experiencing this issue this should be able to be brought to the HOAs attention in a meeting.

You might want to go to the Fantech website, where the manufacture describes the booster fans they make:

»residential.fantech.net/resident···er-fans/

You can install one of these booster fans and use a soffit or fascia vent. You might want to call customer service at Fantech and determine if the pressure from one of the bathroom fans will activate the pressure switch and turn the booster fan on. With a booster fan you will not have to worry about back pressure affecting the performance of your dryer.

I have an old code book so maybe it's under 1502.1 now?

1501 is generic
1502.1 is for dryer exhaust.

The only exception is if the dryer is a ductless dryer (which I have never seen) which apparently comes from the factory without an exhaust pipe.

Had one of these on the yacht. Actually it was a European designed combined washer/dryer. Worked pretty well.

You DON'T ever want to have to vent a dryer out the side on a yacht considering when we hardened the boat and pointed upwind we'd get the gunwale practically awash in a good wind.

You need to do more than that.
The existing exhaust pipe routed up through the house also does not meet code.
Why?
Because it links the garage space with with interior of the home (even though where the vent pipe is run is behind drywall).
Now imagine a garage with a car idling and the dryer on - where do you think the carbon monoxide is going to go? It's going to get drawn into the dryer and then leak into the house through the unsealed ducting.

Without seeing an elevation drawing for the front/side of the house, can you run some approved-for-chimney-use B-vent vertically from the current - or a slightly different dryer location in the garage - to a point on the garage roof that's hidden from street view (ie. wouldn't run afoul of the HOA rules). Sorry I'm not looking at your floor plan drawing at the moment, so forgive me it it's evident that what I'm suggesting isn't possible.

What about coring the house wall 12" above the pavement beside the garage door frame and installing the dryer vent facing the street? Can you hide a vent behind a bush in that area?

Or if the house has a soffit at more or less the garage ceiling level, run the exhaust pipe up the inside garage wall, then over to the soffit, and then vent downwards through the soffit using a 'boot' and install a grill over the boot. All the while making sure that there is NO way for CO gas to leak into the house via your piping.

Ok, looked at your drawing again.....

Common wall between you/neighbour is the kitchen/dining/garage side ... correct? And I see that you have a bedroom partially above the garage.

So sidewall vent to the 'left' is out.
Vertical vent is out unless there's some way to ensure that the house is completely sealed from garage - in my area that means spray foam in the garage ceiling and house wall above the ceiling exposed to the garage, all covered with 5/8" drywall, taped, and mudded - your code may vary.

Can you vent to the right over near your porch?

Best option is still venting to the front via the wall beside left garage door frame.

Best location for laundry appliances would have been beside the porch, and venting through the sidewall onto the porch area.
