Water Leak Tests

You can use various methods in order to inspect for water leaks after the window adhesive dries. Use the first test method for generalized testing. The first test method uses a large volume of water spread to a general area without exceeding the sealing limitations of the glass. Locate the entry point by using the water hose test or the air hose test.
