I'm putting in a new electric dryer in an old 1950's slab-on-grade house has never had a dryer before. I want to put in the vent so that the dryer vents straight out, no bends or angles, also there's not a lot of room for bends and angles behind the dryer.
Being slab on grade, if I am able to vent straight out, the exterior part of the vent will be about maybe 9 -12 inches or so above ground level. Seems that this will make it easy for the various small varmints (voles, shrews etc) crawl in through the vent, even with the little flapper door.
I could put fine mesh on the exterior part of the vent, but that would clog pretty fast with fine lint and whatnot.
Any other ideas? I'm thinking this is a pretty common issue and has already been solved; I'm just not looking in the right places.
