Water can be distributed using a combination of ¼-inch poly tubing with mini-jet sprayers or point-source emission devices and in-line emitter poly tubing to deliver water directly to plants.
Use a drip filter, with a minimum 120 mesh screen, downstream of the timer to remove sediment and other particles that may clog drip irrigation emitters. Pressure-regulating filters are available which combine both the pressure regulator and filter into one unit.
Use a battery-operated, automatic-control timer connected to an exterior faucet or hose-bib attachment. Use in combination with a hose end backflow preventer to prevent any contaminated water from re-entering a domestic water line.
Irrigation of food plants that will be consumed by humans should be from a potable source or a recycled water source of appropriate quality to ensure safety.
