QUESTION
Water purity test to confirm the efficiency of the purifier

After electrolysis of water samples, water changed its colour. In some cases it was Red, others black, blue blackish geen, yellow etc. It was during a demonstration of Water Purifier. The Sales person got this test conducted to prove that water from his purifier was more pure. According to him turning of water colour to pale yellow after electrolysis test is most pure form of water, turining of water to red colour means it contains Iron Rust, to black means it contains heavy metals, blackish green means it contains copper rust,lead. mercury etc. and water turning to blue means it contains organic phosphorus compound.

Does this in anyway constitute a confirmative test for water purity or efficiency of the purifier?
