Integrate notes into the above.
Plants have a watering rating, which may be different.
The nozzles put out water on a basis of gallons per hour.
Of course, if you allow for deeper watering, which is what is recommended, you would do it every other day.
During the winter, once it starts raining you can turn off the water and start it again when it stops raining.
Lawn - best to have a slower, but adequately covering, nozzle, so it can go deeper, watering it a bit more time.
Watering systems have a water pressure. If it is 300 gph
At 1/2 gallon per hour flow rate, the system will use 12 gallons of water in 24 hours.
A half gallon of water will water 1 inch into the soil in a 1 square foot area.
Calculating gph is carried out by measuring the amount of water used to fill a bucket within 30 seconds from the water supply. The level of water is then converted to decimals and divided by 60 minutes. The total of this calculation is then multiplied by the amount of water collected and that total is multiplied by 60 minutes. The sum of these calculations gives the total gph used by the specific drip irrigation system.
Set up emitters with 1 gph rating for shrubs and smaller trees. Reserve the higher gph emitters for larger trees or water-hungry vegetation.
Water requirements vary depending on the plant and its age. Keep plants with similar water needs grouped together, creating a zone; this allows adequate water use for the plants in that zone as well as adjustments in water use as the plants in the zone age.
High and low pressure emitters cannot be combined within a zone. Emitters with the same gph can be added or subtracted from the zone as water requirements change

Once a drip irrigation system is in place, little maintenance is required besides annual flushing. However, when a problem occurs, finding leaks can be difficult if the piping is underground, or if the hole is tiny. Repairing, once the drip is found, is as simple as changing out hoses.
