Show me the Solapure working...

We sometimes get asked, how do I know if my Solapure is working - well there is a very simple test.

On a sunny day put the Solapure in a clear container, without the cage making sure the spring does not make direct contact with the core. After about 15 seconds you should see fine air bubbles forming on the coils of the spring as shown. This confirms the unit is working.
