Pressure-regulated Sprinkler Heads

High water pressure is great in the shower, but it can lead to water loss and maintenance issues in an irrigation system - leading to increased evaporation, more water carried away with the wind, and less water getting to your grass. This causes poor coverage and some areas of your lawn will be over watered, while others are under watered. The right pressure for your sprinklers will result in using less water for a healthier lawn.

Different types of sprinklers work best with different levels of pressure.

When switching your original sprinklers with pressure regulated ones, you could save an average of 32,000 gallons per year! That’s enough to fill 320 bathtubs!

Inspect sprinklers once a month
A simple look at your irrigation system can help save you water and money. Watch your system run once each month during the summer, pick a day of the month and stick to it.
