My outside dryer outlet pipe exhausts below grade. I am told there is a vent fitting that turns the direction of the exhaust up to get above ground level. Then it has a cap to keep rain, etc out. Stores here have heard of such a product but do not know where to get one. Any advice??
your better off just raising the vent rather than taking a chance of rain entering it. The device your talking about is really not water tight (100%) and you honestly do not want to restrict the vent exhaust.
