[NMR Pipe Protector Verification Results] Izu Ohni Country Club

The progress of red rust completely stopped just one month after installation! A case where the discoloration of the filter also decreased!

This property has been in existence for 33 years, and due to significant red rust blockage at the joints of dissimilar metals in the water supply pipes, we adopted the pipe rehabilitation device "NMR Pipe Protector." Before the installation of the NMR Pipe Protector, a white filter was attached to the kitchen sink water supply faucet for seven days, during which the filter became discolored to a brownish color due to the red rust generated in the water supply pipes. After dissolving the captured iron content with purified water and measuring the iron concentration, it was found that the iron concentration in the water was 21 mg/l, indicating that the red rust corrosion in the pipes was very advanced. One month after installation, a white filter was attached under the same conditions as before, and it was confirmed that the discoloration of the filter had reduced to light brown, with the iron concentration decreasing significantly to 5.8 mg/l. Furthermore, six months after installation, a white filter was again attached under the same conditions, and it was confirmed that the filter's discoloration had nearly reduced to white, with the iron concentration further decreasing significantly to 0.75 mg/l. From this, it can be concluded that just one month after the installation of the NMR Pipe Protector, the progression of red rust was completely halted, and at the same time, the surface of the red rust in the water supply pipes transformed into a non-soluble black rust, resulting in a reduction of iron leaching into the water and a decrease in filter discoloration.
