GF100 Gravity Feed Drip Kit

GF100 Gravity Feed Drip Kit

DIG’s GF100 gravity-feed kit is a complete kit designed to connect to an elevated rain barrel. Using a gravity-feed system to distribute stored rainwater via drip irrigation is the most efficient way to irrigate, saving both water and energy. Rainwater used in gravity-feed systems is free of the chemicals, salts and minerals found in your traditional home water supply. The GF100 is great for watering vegetables, roses, vines and shrubs, starting from a raised rain barrel with a hose thread outlet or from a garden faucet using the included pressure regulator. The kit includes a 3/4″ 155-mesh filter, 3/4″ swivel adapter, 100′ of our premium 1/2″ drip tubing with .700″ OD, 50′ of 1/4″ micro tubing, 50 button drippers, and all of the necessary parts to complete the installation.


  • Complete kit including all the parts needed to start a system from a 6o to 200 gal. rain barrel (not included)
  • Drip emitters’ turbulent flow path through a unique labyrinth water passage reduces likelihood of clogging
  • Raised barbed outlet prevents water runoff along the drip lateral
  • Operating pressure is controlled by the height of the rain barrel (the higher the barrel, the higher the flow rate from the drippers)
  • Constructed of UV-resistant, durable plastic material to withstand the most adverse conditions

DIG’s GF100 Gravity Feed Drip Irrigation Kit

The GF100 kit can be used for a typical gravity feed system with rainwater collected and stored in an elevated barrel or tank. Use an elevated barrel or several barrels connected with an outlet at the bottom that feeds the water into your drip irrigation system. Connect the kit to the elevated tank that provides the minimum pressure for a drip irrigation system to deliver the water to the plants.

This is an effective way to water a small-sized garden or crop area and it is a cost-effective method of watering in a seasonal pattern climate area. Keep the elevated barrel(s) or holding tank(s) filled using rain harvesting collocation procedures.

About Rain Barrels or a Rainwater Harvesting System

Rainwater harvesting or a gravity feed collection system that collects and stores rainfall for irrigation, ranges from a simple elevated rain barrel to a more elaborate system with several tanks connected.  The collected rainwater can be used to irrigate your garden or for other uses, such as washing your car. With short water supply in many densely populated regions of the world, rainwater collection systems can provide additional watering options in the dry seasons.

The simplest rainwater harvesting, or gravity feed systems are non-pressurized systems, such as elevated rain barrels, where the barrel from rain gutters into a tank. The barrel or tank do not hold any water in the pipes after it stops raining and do not create breeding grounds for insects. In areas where the tank is located away from the collection surfaces, or where there are a series of tanks, pipes from the gutter may run along the wall and then into the tank.

Well-designed rainwater harvesting systems ensure that the pipes and all other openings are insect-proof, especially in wet systems. Additionally, a screen filter with 150 mesh or higher on the outlet side can prevent debris from clogging the drip system.
