a wet syestem always has water behind the head it is charged with water at all times all the pipeing is water.. wet system usually used in doors
a dry system has a diffrent type of valve allowing a clapper inside the valve to have water from the underground being held back by air in which the system is charged with air until the valve trips (usually sprinkler being popped or very low air pressure) so the sprinkler system it self on a dry valve contains air until tripped then water flowes when tripped usually used outside parking garages and canopys or where very cold

What is the difference between wet-on-wet and wet-on-dry painting?
"Wet on wet" or "wet in wet" means that you are applying wet paint (usually oil, artist's colours) to a surface that you have already painted which is still wet. If using oil, then your surface would be oil based, such as linseed oil or turpentine. This technique enables you to move and blend the paint to finish a painting in one sitting. "Wet on dry" means you are applying wet paint to a dry surface that you have painted earlier and allowed to dry. You can do this to either build up an area, or as in glazing, to achieve certain effects.
