Please note: any brand of air inflated test balloons can be dangerous if not used per manufacturer instructions. Please also make sure when you use a test ball/plug, that you have a way of getting the water out of the pipe safely. So please plan ahead. Sticking your hand up a test tee to let the air out of a inflated test ball can cost you some fingers! Water pressure and air pressure can be dangerous for the unsuspecting. In our opinion inflatable test balls should have a chain tied to the pipe and an extension hose to let the air out slowly from a point where your fingers are safe. A test plug should be supported so that it won't slip out of the pipe under pressure.
