Introduction :
Sales people from various water purifier companies of late are making use of a so called “Precipitator” or Jam Jar Purity Test to supposedly prove that all water except for the water produced via their purification equipment, is impure and subsequently unsafe for human consumption.

Read below to get the full picture.

The Jam Jar Test is basically a very crude, rudimentary, electrical circuit, similar to a car battery or scientifically known as an electrochemical circuit. When used as a so-called “Precipitator” it gives the customer the impression that the water is not safe to drink. It does this by precipitating or electrochemically introducing natural salts into the water that appears as a brown “goo”, which makes the water look awfully dirty.

Note: Water purified using a reverse osmosis system (RO) has very little or no minerals present in the water, thus the water will not conduct electricity and the precipitation will not result.

The TDS Test is also being used by certain Sales People to test the water. This tester measures the amount of Total Dissolved Salts(TDS) in the water.

Salesman could measure normal or purified water with a higher mineral count than RO and could state that if the water has a high TDS content then it is impure and unhealthy. TDS alone is not an indication of the safety of the water as it only tests the mineral content.

   

BEWARE OF THIS SCAM

Why does the water change colour?

It is simply explained :

  1. Reverse Osmosis (RO ) water contains very little to no minerals .
  2. This water does not conduct electricity since to conduct electricity minerals need to be present in the water.
  3. When electricity is not present then none of the chemical reactions can occur. Therefore no discolouration will be visible in the RO water.

Relative to water which contains no minerals.

  1. The water they compare the RO water to contains minerals.
  2. These minerals will allow electricity to flow as current through the water.
  3. This subsequently allows the precipitation and an electrochemical reaction to take place which discolours the water. The change in colour can show up as a grey precipitate or brown sludge.
  4. This colour change is normal and can be expected.

WHAT YOU MAY BE TOLD….

Because there is no reaction with the RO water, salespeople could claim that the RO water is less contaminated and that other so-called purified waters, bottled waters or tap waters are dirty and contain unhealthy levels of impurities. What you may not be aware of is that there are naturally occurring minerals in purified or bottled water.

DO NOT BE FOOLED OR PERSUADED THAT THIS COLOUR CHANGE IS AN INDICATION OF IMPURITIES IN WATER!
