About Drain Test Plugs, Air Bags & Test Pumps

Test plugs can seal or block off drain pipes before air testing, and can be used as a temporary plug in drainage systems such as in showers or bathtubs. The air bags are used for pressure testing pipe work. Ideal for areas where the access opening is smaller than the test diameter or where the test point is some distance from the point of access.
