A week or so ago, my shower spouted one temperature of water: luke-warm. I complained, and a plumber came in to fix it. I asssumed that all was well, but the next day, I discovered that no water came from that shower at all. I have another shower stall, but that one was filled with pictures awaiting hanging on my walls.
Soon my niece came to visit, so fortunately she did the heavy lifting and we cleaned out the guest shower stall. I'd never tried that shower, but we discovered that it worked fine.
Fast-forward a week: today, three plumbers arrived at my door. After a lot of effort and two visits, they got my shower working again, or at least I hope so. Actually, one shower is enough for me, but I prefer the more convenient one. Besides, I may have a guest again in the future.
I'm beginning to appreciate the complications of getting a large high-rise building up and running.
