Hello vijayppt,

Along with Boreks suggetion, you could take regular litmus paper, and wet it in distilled water.  When you place the water-wet litmus paper over the leak, the pH will increase (turning the litmus paper blue).  The paper must be wet in order for this to work.

Just a suggestion,

Eugene
