Reliability Questions

Q: How will Precision Series Spray Nozzles stand up to water with high mineral content? Will they clog up with calcium deposits?
A:

The H2O Chips have been tested for performance in hard water and found to be reliable. This is primarily because the critical surfaces are only exposed to sunlight when the nozzles are spraying water; otherwise, they are protected below the surface of the wiper seal. No sun means no evaporation, and no evaporation means no hard water mineral deposits. In addition, the physical properties of PBT make the chip’s flow path highly resistant to mineral deposits.

Q: What about debris?
A:

You’ll notice the filter screen is attached to the nozzle body – at the factory - to ensure it is properly positioned and attached to the nozzle housing. This assures that each Precision Spray Nozzle is installed and operated with the correct screen; preventing harmful contamination from entering the H2O Chip. The screen is designed so that anything passing through the screen will pass through the nozzle and the H2O Chips. While the screen can be removed and cleaned if it becomes clogged, it is critically important to re-attach the screen before re-installing the nozzle (see next question). For all intents and purposes, the warranty is void on the nozzle if it is operated without the screen.

Q: The screens for the 15’ Series look different than the screens for the other models. Why is that?
A:

There is one screen (26 mesh, 560 microns) for the 15’ Precision Spray Nozzles and a finer mesh screen (45 mesh, 306 microns) for the other models: 5’, 8’, 10’ and 12’ nozzles. The screen with the little tip extension at the end is the finer mesh screen.

Q: What kind of material are most spray nozzles made out of?
A:

ABS Plastic.
Q: What kind of material are Precision Spray Nozzles made out of?
A:

PBT Plastic (Polybutylene Terephthalate).

Q: Is PBT a better plastic?
A:

PBT is a highly engineered plastic that is harder than ABS. It has been chosen for the Precision Spray Nozzles and H2O chips because of its physical properties. It also has a much lower coefficient of friction so there is less energy loss as water travels across the surface of the H2O Chip molded out of PBT Plastic.

Q: Won’t the micro-vortexes of water that continuously form and collapse rapidly inside the H2O chip wear out the plastic?
A:

NO. PBT Plastic has chemical and physical properties that are uniquely designed to handle the turbulent water flow inside the chip. PBT is a highly engineered plastic that is harder and smoother than ABS, so less friction and abrasion occurs with PBT than ABS. Think of it as a “Super Teflon” surface. Also, the amount of water flowing through any Precision Spray Nozzle is at least 35% lower than conventional, competitive spray nozzles so there is less water to wear out a harder plastic.
