Thank you for sharing your experience and for mentioning the water treatment company. Our borehole is approximately 60 meters deep, with the submersible pump installed at around 40 meters. Although the well water appears bright and clear, I decided to install two “Big Blue” filter housings as a precaution. One is fitted with a 20-micron cartridge and the other with a 5-micron cartridge. Despite the clarity of the water, it is also very hard - the poor soap lather during showers is a clear indication of that. After reading your post, I hope the hardness will not damage the internal components of either the 750-W submersible pump or the Grundfos SCALA2 pump. Until now, I had not realized that some well water could be aggressive enough to cause the type of deterioration you described, particularly to metal fittings and pump components. I appreciate you bringing this to my attention. Once I receive the results of the well-water analysis from Rajabhat University, I will certainly consider consulting PP Water for their recommendations on appropriate treatment options. I will also update this thread with the findings and any solutions implemented.
