Tonight's installation of Chinese Apartment Maintenance is on plumbing. I am batting 1000% for water hoses busting on every place I've lived in China. Tonight my under kitchen sink main hose erupted, but I know where the water closet for my floor is and rushed outside to close the valve to my apartment. May as well have been toting at windmills.
So, with all my prodigious might, I closed the larger valve feeding all 6 apartments. This reduced the leak in my kitchen about 90%. I redoubled my efforts. 95%. Best I can do without fear of destroying the crappy valve.
I sorta figured that if I cut off the water to six apartments that people might come outside and take a look, or maybe call maintenance and someone would come to check. Nope.
Wait, wait, someone emerged and turned the water back on. Thank goodness!
