Winterize irrigation pump sprinkler system???

[u/davemill123]

I have a sprinkler system that the water is supplied by an underground well via an irrigation pump. The pump has a faucet (manual calls a “primer opener”) on the discharge pipe. Freezing weather is coming. Can I connect an air compressor hose to that faucet to blow out (winterize) the sprinkler system? This is my first post on Reddit. Thank you for any advise/help.
