Just one note on the crack shack - they had a water softener there- It just wasn't maintained.
The likely possibility is that nobody did routine maintenance on the system.
Makes sense. I think you would have to have such a system if you're drawing from well water instead of a municipal supply.
I know many municipal sources are hard water that can cause calcium deposits (nasty white shit), but I have
never known them to have that high enough of an iron content to turn the water rust colored.
Nick much rather spend his money on stupid toys rather than routine home maintenance. Plus, he was out of that house, and possibly didn't give a shit about the tenants he had there.
He is lucky he did no get sued for the filtration system not being maintained and in violation of MN code. As a landlord he was liable for failing to maintain the water quality.
Knowing Nick, he'd throw a tantrum if they asked him to fix it. Because, no matter how politely they would have asked, he would have interpreted them asking him in a "faggy manner."
Then he would pull up a Quora article by some discredited scientist explaining that that high of an iron content is actually good and turns you into a sexual Tyrannosaurs, and the government filtration standards are all driven by racism, and written by Scandinavian incel prudes. Also, fluoridation of water is a Communist plot meant to pollute his "precious bodily fluids." The most precious of all being his cum (which, BTW, did you know that Aaron ate his cum?).
So basically, I wouldn't blame those tenants if they just kept their mouths shut. To preserve their own sanity.
