I screwed up. Advice?

25M recent homeowner as of right before winter. Just scrolling through various homeowner subreddits, read about someone not winterizing their sprinkler system and pipes. Thought to myself, “hey, I didn’t do anything to winterize my pipes”. Went to check it out and found that I screwed up big time.

What immediate actions can I take?

I have a 15k emergency fund, how much of that will I need to repair this, or will it be more?

Thank you for any help.
