Indoor plumbing. We all take it for granted until it backs up.
Tub wouldn't drain. Toilet wouldn't either. Tried some liquid drain cleaner. No luck. Called a plumber. He removed the toilet, unclogged the pipes and put it all back together. Told me I was "good to go".
That's been my day so far. I am positively grateful for indoor plumbing and good plumbers.
Not much else to say about plumbing, so I thought I'd share these pictures of my bathroom in my tent while I was on Safari in Kenya several years ago.
