Common Misperceptions about MP Rotator Sprinklers

Monday, July 29, 2013

Misperceptions can come from any number of sources. Sometimes a friend or family member can lead us astray or sometimes a recognized authority or expert can get it wrong. Most often the person that starts it or perpetuates it does not have bad intentions, nor are they intentionally lying. They really believe it, and it is hard to get them to move off their position, because it seems to make sense. Here are some common misperceptions that never seem to go away:

Misperception: If you swallow a piece of chewing gum, it takes seven years to digest.

Fact: According to the Kids Health web site, although swallowed gum does not break down during digestion, it passes through the digestive system at the same rate as other matter.

Misperception: Twinkies have a very long shelf life, some saying it actually will last longer than the cellophane it is wrapped in.

Fact: The Snopes web site says the Twinkie does not have an infinite shelf life; its listed shelf life is approximately 25 days and generally remains on a store shelf for only 7 to 10 days.

There are hundreds, if not thousands of these types of ideas which may seem logical, but when the facts are explained, they do not hold up. They linger because people have heard them somewhere and keep repeating them so they take on a life of their own and never seem to go away.

The same is true of the Hunter MP Rotator, rotating-stream sprinkler. Although it’s been on the market in the landscape irrigation industry for nearly a decade, there are a number of misperceptions that continue to follow it despite evidence that negates each one. We’re going to look at each one of these common misperceptions, and provide you with the facts that show the MP to be a wise choice when it comes to efficient irrigation.

Misperception: MP rotators are more expensive to install than traditional spray nozzles.

Fact:  Individual MP Rotators are more expensive than a standard spray nozzle, but an irrigation system designed with MP Rotators can be less expensive to install since it requires fewer valves, a smaller amount of pipe and fittings, a smaller controller, and less labor. Couple that with the water savings over the life of the system because of the increased efficiency over sprays, and the cost of ownership on the irrigation system is also lower.

Misperception: MP Rotators put out the same amount of water as traditional spray nozzles.

Fact: This seems to be logical since MPs are normally attached to spray head bodies, and often times are used to replace spray nozzles. Actually, MP Rotators apply water at a rate of about ¼ of the rate of traditional spray nozzles of comparable radius. This helps in the efficiency area as MP Rotators apply water at a slower rate—a rate at which soil can better absorb the application of water.

Misperception: Low precipitation rate just means longer run times.

Fact: This misperception is partly true—MP Rotators do need longer run times than traditional spray nozzles. However, since a low precipitation rate is required for most soil types, these longer run times are required for MP Rotators with their low precipitation rates, to let them apply enough water. Spray nozzles put down water at a rate faster than soils can absorb leading to runoff and water waste. When you design a new system with MP Rotators, each zone can cover more area because the lower flow rate through each sprinkler allows you to have more heads on a zone. This makes for fewer zones, and most often allows you the same amount of total watering time when compared to spray systems with many more zones.

Misperception: MP1000 waters at a lower application rate than other models.

Fact: The shorter radius application size of the MP1000 does require less water than a larger area.  However, all MP Models deliver water at the same exact precipitation rate of 0.4”/hr.  This makes it easy to design and install with MPs, as you can mix and match sizes and types, and still maintain matched precipitation.

Misperception: MP Rotators are not dirt tolerant.

Fact: According to extensive testing done onsite at Hunter, the MP Rotator is the most dirt tolerant of all rotating stream sprinklers in the industry. The technology used in the MP has been around since 1987 in the agricultural irrigation market, and it has proven to be extremely reliable. Case studies from areas with water that has high mineral content, as well as areas with poor water quality all point to the reliability of the MP in harsh environments.

Misperception: MP Rotators are more difficult to maintain.

Fact:  Extreme dirt tolerance, chemically resistant materials, and an easily removable filter make for easy maintenance and a long, useful life. These features coupled with easy adjustment and set-up make for a sprinkler that is simple to work on, and rarely needs attention.

There are likely other misperceptions out there about the MP Rotator that we have yet to hear, but whenever anyone tries them out, they tend to stick with them as their go-to sprinkler for areas with spacing from 8 feet to 35 feet. The reality is that the MP Rotator is a solid, water-efficient sprinkler that can save water, and produce outstanding results.
