SWC 160's Atman 2500 pump does not work

[swimmingswammi]

So I bought this skimmer used. It worked for at least a few days for me then stopped working. So I bought a replacement Atman 2500 and that one worked for a few days and now does not work.

I have opened them both up and cannot determine why they have stopped working. Any thoughts?

It's happened to me numerous times,,,you have to blow in the air line hose,, trust me it will work.
