Non-pressurized Systems are simply a barrel (55 gal plastic drum) or larger tank which sits directly below a gutter downspout and has a hose attachment for watering plants, gardens, etc. These systems simply use gravity to move the water and have no pumps or other equipment. They are very effective for drip irrigation.
Pressurized systems are typically larger (500 gallons or more) and have a pump and pressure tank attached. These are used when connecting to a lawn sprinkler system in which high pressure (30-60 psi) is required.
