If secondary air injection pump fails, do I need to replace the entire system?

What is your question?

If one secondary air injection pump fails, do I need to replace the entire system? A mechanic told me that, if a pump fails, it floods the air system with a foam and you need to replace the entire air injection system. (2 AIR PUMPS, 2 SWITCHING VALVES, PIPE FOR AIR PUMPS, HOSES W/CLAMPS, GASKETS FOR SWITCHING VALVES)
