Did you know that Charlotte has a long history of high water pressure problems? Today, most Charlotte homes have higher water pressure than needed for optimal appliance function. Unfortunately, the problems caused by this high water pressure don’t stop at your home appliances. Most Charlotte irrigation systems also suffer the consequences of this excess pressure.
Have you ever watched a sprinkler running and noticed a “mist” being produced? That mist is an indication of high water pressure. Irrigation heads are designed to use 30 to 40 psi of pressure, but most Charlotte homes maintain at least 60 psi of pressure. In fact, it’s not uncommon to find a Charlotte home with 120 psi or higher!
While this misting may produce what appear to be small rainbows in the sunlight, it’s more accurate to imagine your hard-earned dollars floating away in that mist. As the excess water pressure causes increased flow and velocity, large amounts of water are being released in the form of a mist rather than reaching the intended irrigation target. With the prevalence of droughts and increasing water costs, the costs associated with this wasted water can be substantial.
Pressure Regulating Systems
The solution to this high water pressure problem is to use a Pressure Regulating System (PRS) irrigation head, such as a Rain Bird® 1800-PRS Series Spray Head. These irrigation heads have patented PRS pressure regulators built into their stems that maintain optimum water pressure for ideal spray nozzle performance.
By regulating the high water pressure at the head, PRS irrigation heads can help you save approximately one gallon per minute per rotor or spray. This could result in the average homeowner saving thousands of gallons of water each season.
The Rain Bird® 1800-PRS Series Spray Head, for examples, ensures optimal nozzle performance at 45 psi. When you consider that it has been estimated that every 5 psi reduction in pressure reduces water usage by 6-8%, you could be looking at an 18% reduction in your water usage. That reduction means more money in your wallet!
“Given the recent increases in droughts and high water prices, cutting back on water usage is an easy way to save money,” says John Minor of Irrigation & Lighting Specialist. “Using PRS heads is one of the best ways to reduce your water bill and maintain a healthy lawn."
Saving water is not the only benefit that PRS heads can provide. Below are a few of the additional benefits offered:
- Eliminates head to head pressure variation.
- Improves distribution uniformity.
- Extends system life by minimizing wear and tear caused by excess pressure.
