Leaks in plastic pipe joints are caused by poor welding or gluing and permanent repair requires cutting the joint apart.
These are thought to occur when the fluid-filled sac within joints gets stretched by a sudden change in joint position. The resulting pressure and volume change, pulls some dissolved gases out of solution [from the joint fluid] and the gases make bubbles that are unstable and pop.
