Use a spark tester to test your plastic welds for leaks. Run the spark tester along the weld and if there is a hole, a harmless spark will go through the hole.
- Easy to use
- Easily repair welds without filling your container with water to test for leaks
- Normal applications are usually less than a minute
- Where continuous use is required, the tester must be turned off to cool after ten minutes
