PRESSURE REGULATION SAVES WATER & MONEY

Historically, most irrigation systems don't have pressure regulated sprinklers which often leads to sprinklers operating over pressurized. Over-pressurization can lead to water losses and contribute to uneven watering.

Pressure-regulating spray heads are a developing technology designed to regulate pressure to optimal performance. Pressure-regulating spray heads include built-in regulators that maintain a more constant pressure for optimal nozzle performance.


WHY IS PRESSURE REGULATION IMPORTANT? 

Two reasons: They will save water and it is likely soon to be the law. 


WATER SAVINGS: Compared with non-regulated, pressure regulated sprinklers will use about 20-25 percent less water. And if the nozzle breaks, pressure regulators are estimated to save 70 percent of the water that might have been spilled if using an older, non-pressure regulated system.

PRESSURE REGULATED SPRINKLERS NOW REQUIRED BY LAW:  California and Washington along with Colorado, Hawaii, Vermont have all previously adopted banning the sale of non-pressure regulated spray heads in previous years. This past year, the Oregon Landscape Contractors Association sponsored a bill to do the same in Oregon. We firmly supported this effort which was signed into law this year. Although we hate new regulations, but this one makes good financial sense. 


SAM-PRS Spray Heads 

We are converting our spray head inventory to those with Pressure Regulation (PRS) and Check Valves (SAM). Per above, PRS is becoming the law but both PRS, and SAM save water.

  • Built in PRS pressure regulator maintains constant outlet pressure at 30psi ensuring maximum nozzle performance, even with varying inlet pressures. Saves 20-30% water compared to standard heads.
  • Restricts water loss by up to 70% if nozzle is removed or damaged.
  • Built-in Seal-A-Matic© (SAM) check valve eliminates low head drainage from spray heads located at the base of slopes or hillsides.

As a part of our water conservation programs, we will be recommending replacing spray heads with SAM-PRS heads to save 20-30% in water use and cost.


MP Rotator

MP Rotator is a revolutionary alternative to traditional sprinkler heads and pop up sprinkler heads that spray the landscape. MP Rotator nozzles feature unique, multi-trajectory rotating streams that deliver water at a steady rate. This slower application rate allows water to gently soak in at rates that soils can absorb.

As a part of our water conservation programs, we will be recommending replacing some spray heads with MP Rotator for even more water savings of up to 40%.
