for others benefit my contractor after asking about the MP Rotors option came back with this configuration:
FYI - this is what the contractor came back with:
Areas of coverage: Front grass up to fence line, front garden, side and back grass, back cedars as discussed on site.
Our estimate for the design and build of the irrigation system is based on the supply and installation of the following:
9 – Rain Bird, 1804, 4” spray head
30 – Rain Bird, 1804 with MP Rotor nozzles
12 – Rain Bird, 1” solenoid valve
Plus, all polyethylene pipe, and multi-strand direct burial control cable. Insert fittings with all-stainless steel clamps and all other related items required to provide a completely operational lawn watering system of the highest professional quality.
Our estimate starts at a ½” water supply located on the back of the house. We will install the homeowner supplied Rachio controller in the garage. Backflow prevention devices are required by the plumbing code for all irrigation systems to protect the drinking water from contamination. A Dual Check type backflow preventer is included in our proposal.
Our installations are guaranteed for a period of two years from the date of installation for the quality of workmanship and materials. Also, included in our guarantee is the first-year winterization of the system at no extra cost.
