That is $3000 my dude, which is easily a single plumbing problem

If you mean busted water and all the repairs, sure, but that’s on the landlord for not ever checking on their property (unless the tenant did something very stupid, which is possible)

I own my home and just had some plumbing work done in California (king of expensive) and 3k is about 10x what it cost me for a couple hours of plumber work
