I am looking for a misting setup that you install over your patio. It does not consist of any machinery. Its a simple flexable hose with several fine misting attachments that hangs over a patio or awning. This in turn actually cools the patio area like an outside air conditioner. I've seen a few on the internet that need an air compressor hookup but, I have seen (somewhere) on television a simple setup that hooks directly to your water hose or spicket so it works from water pressure only.
