Pics from unit. So charlie you say that it is not allowed to have return air pulled from a bathroom or kitchen? i knew garage was a nono… i want to get back to this guy and would like to understand why. Kitchen is explainable, fire, gas from stove pilot ect. Garage is self explanitory…but bathroom? what is the logic here?

You have moisture entering the system, as Bob said negative pressure from mechanical exhaust (if there is one) and the Aroma (oder) from bath entering the return/supply.

That is from the 2006 International Residential Code pg 339

I suppose Uncle Aldo might have the skills to create enough methane to blow up the joint after a good burrito dinner.:eek:

thanks for all of the help!!!

I cant get the photos to load. Only one that loaded was the return pic…doesnt say much. I will email them to you charlie.

Think someone in the shower and the A/C/heater kicks on with a return air in the bathroom where does all the moisture go not out the exhaust fan because it is being over rode by a much larger CFM. Same principle with a kitchen exhaust fan which is larger do the math;-)

As for the bathroom; what do you thing happens when you shut the door?

Plumbing fixtures turn into mini-jacuzzi’s. great way to turn your toilet into a bidet!

George, though it may pass construction standards it is still “wrong” (For other reasons).
