DIG G77AS Installation Instructions

Watering Recommendation:
Example: Shrubs up to 4 feet high we recommend 2 gallons per day in the summer. The recommended flow rate can be
achieved using 2, 1-GPH drip emitters. These guidelines are suitable for most areas and soils.
Note: Plants larger than 2 feet in diameter should have more than 1-drip emitter per plant to cover the plants root zone.
Watering Time:
Run the system 45 minutes to 3 hours every 2-5 days, depending on your location (cool to warm) and soil type. After a week
check the soil, the health of the plants, and adjust the watering time as needed.

Thank you for purchasing the DIG Model G77AS Drip Watering Kit. Please take the time to read through the enclosed
instructions and follow them step by step. If you have any questions, please call our customer service line at

Follow these guidelines for the design and installation of a cost effective and reliable drip irrigation system in a landscape
area, which promotes efficient water use and protects our natural resources.
When designing your system, make sure to have a design drawing before you start the job. Design drawings should be
clearly readable to scale and should include water source location, layout of the poly tubing, drip emitters, fittings, end line
for flushing, plant materials and sidewalks. Different species and sizes of plants will have different water requirements, so
take into account the plant type, location, size and soil type. Trees, shrubs, roses, and vegetables within a different height
and size will require a different number of drip emitters per plant. This will require measuring the area you wish to water. We
recommend using graph paper, this will make drawing to scale easier.
