Weather station, pager access, or moisture sensor accessory for Smart Controller (above)
Most smart controllers now available include the option of connecting to a weather station (either on-site or satellite with pager access) or soil moisture sensors. If purchased with the Smart Controller, the rebate applies.

Weather station, pager access, or moisture sensor accessory added to existing system.
This product can be added to an existing control clock to automatically change watering schedules according to the weather (onsite or satellite-by-pager) or soil moisture sensors.

Pressure regulator:
Most (but not all) homes in Utah have too-high water pressure, which causes both excess wear on irrigation valves and fittings, and misting, which wastes water through evaporation. Too-high pressure also impacts the function of valves. If the pressure is over 50 psi, a pressure regulator should be installed. These are available for entire systems or for individual valves or sprinklers. (These should not be confused with “pressure reducers” that sell for under $20 and are actually backflow preventers.)

Low precipitation stream-spray nozzles:
Very uniform, low water use spray heads shown to be effective in conservation. Best-known brand is MP Rotator, or consult irrigation specialty store for new entries into market.
Bubblers:
Look like regular spray heads but either bubble only or spray downward. Best for use under shrubs and near trees.
Xeri-sprays and xeri-pops:
Fine directed spray heads; xeri-pops “pop up” like regular spray heads
Drip emitters:
Fit on regular sprinkler risers, but have sections of spaghetti tubing extending to individual plants.
