Hello all again,
I got the magnets and did the test. Without getting under the house in the crawl space, I can only install 1 system of 2 magnets for the cold water. I have a valve right behind where the magnets installed. The sample treated water is freshly flown through the magnets, not standing water in the pipe. I tested the water and took pictures of the results, but the outputs were terrible, because of the mirror reflection, and not worth posting. I did the tests with 3 samples: (a) tap water, (b) treated water, and (c) treated water left over night in a cup. The samples were tested on a mirror and were in the sun to dried out. Before I used a sample water, I religiously rinsed the equipments with reverse osmosis filered water to minimize contamination of previous sample.
Test #1 - Mirror was placed on a horizontal surface. 1, 2, and 5 drops of each samples were put on the mirror.
- Amount of residue were pretty much the same on 3 samples.
Test #2 - Mirror leaned against the wall almost vertically. 3 sprays of each sample.
- (b) is 40% less residue than (a). (c) is right in between (a) and (b).
- I don't know why but (a) has finer mist than (b) and (c). This could lead to less run off; and thus, more residue.
Test #3 - Initially, mirror was placed horizontally. 5 drops of each samples were placed on mirror. Mirror was raised to a vertical position to test the run off.
- The samples ran down at the same pace. Width of streams were pretty much the same. Amount of water droplets remained after samples stopped running were pretty much the same except that those of (b) and (c) were a little smaller than (a).
Test #4 - Exactly like test #3 but only 1 drop of each sample was used.
- The samples ran down at the same pace. As the sample drops rolled down, they created water streams behind them. Most interesting is that the tail of (a) stream disappeared slower than that of (b) stream. (a) streams also broke up more frequently than (b) streams. As the result, there were more of (a) droplets left behind than of (b). I did the the test 3 times and each time I exchanged their position on the mirror to make sure that the results were not affected by the mirror. The results were pretty consistent. (a) had 10, 12, 12 droplets and (b) had 6, 9, 8 droplets. (c) were pretty much in the middle: 8, 11, 11.
Of all 4 tests, only test #4 is the most conclusive. It does indicate that treated water can reduce scaling up to 40%. Test #3 does show a little improvement but not too impressive.
How did the test with my neighbor water come out so different? Could it be that he used 2 systems of 4 magnets while I only use 1 system of 2 magnets? I will have to find out later.
My ultimate test would be hosing down one side of my truck with tap water and the other side with treated water. But that just has to wait because I just have my truck detailed.
I hope my tests help.
Have a nice day!!!
