Vary disturbing situation.
I heard many homeless get a gym membership and shower at the gym.

San Francisco doesn't have any toilets, they just poop on the street and they pay people to clean it up.
Needles and poop, San Fran, is that California living or What?
You have to wear your mask, but you can use the sidewalk as a toilet, very backwards bunch.

As far back as I can remember, one of the first things I learned from dad was fixing all things having to do with water. And from mom, learning to keep all those things clean. Never ever paid for a plumber.....nothing against plumbers but unless you are doing high volume, pressure, or commercial work steam fitter rating stuff..... if you have running water and a drain it ain't rocket science.
