The Yokohama City Waterworks Bureau has verified that there is no rust prevention effect in areas with low water usage.
The Yokohama City Waterworks Bureau has verified that the red rust prevention device "NMR Pipe Protector" does not demonstrate rust prevention effects when water usage is below the specified level.
At the Yokohama City Waterworks Bureau, based on the confirmation of the effectiveness of rust prevention and residual chlorine reduction at the Tsurumi public housing water supply pipe (first test) and the verification of residual chlorine reduction at the water distribution pipe (main water pipe) (second test), residential areas with a low number of water contracts and low water usage were selected. A test was conducted using a 50A water branch pipe in March 2016 to determine how little water usage is acceptable for the application of the NMR pipe protector. The areas chosen were Teramae 2-chome, which has a small number of households, and Konan Chuo area, where tests were conducted to evaluate the rust prevention effect and residual chlorine reduction effect of the NMR pipe protector. The guideline for demonstrating the rust prevention effect of the 50A piping is that approximately 15 tons of water usage per day is required for about 30 households. In contrast, in the Teramae 2-chome area, there were only 18 households downstream of the sampling location, while in the Konan Chuo area, there were only 3 households downstream of the sampling location. In both areas, the minimum water usage required for the NMR pipe protector to function effectively could not be secured, and therefore, its effects were not clearly observed. It was determined that the application of the NMR pipe protector was unsuitable for both the Teramae 2-chome and Konan Chuo areas, and the verification of the rust prevention effect of the NMR pipe protector, along with the associated residual chlorine reduction effect, was concluded as there were no suitable locations for the NMR pipe protector within the Yokohama City Waterworks Bureau other than these two areas.

basic information
Currently, some self-proclaimed scholars are using the internet to defame the NMR Pipe Protector by focusing solely on the third test results under conditions that are not applicable, as part of their efforts to disrupt its sales, specifically targeting the Yokohama City Waterworks Bureau. Please be cautious of this. It is natural that all devices in the world have their applicable ranges, and it is to be expected that they will not demonstrate effectiveness when used under conditions that fall outside of those ranges. The most important condition for the physical phenomenon that produces the effect of the NMR Pipe Protector is the kinetic energy of water, meaning whether the water usage can be secured. The water usage is determined by the diameter of the piping used with the NMR Pipe Protector.
