Ok..so how many holes in the concrete would I need..lol
i hear you no easy way i can see. if was me and these my only options i'd go thru the door<Frame it> wit 8", 6" from there to tfor outlet and put the 4" reducer there. At the door put up mesh to catch any back draft lint and a damper before the Y, wether u use a 4" or 6" is up to u
With both lights running its over 93 ..that's exhausting through hood and out.
If I put another hole at bottom of wall and intake to the hood will this bring it down a lot ? And would that goto the dryer as well? Or just into the laundry room itself
