Well, I've been back and forth on the phone with the water company (actually a really polite and helpful bunch). I created a bit of rapport with one guy who is really going out of his way to help. He said the bill (which is for 1 month) is crazy for a single guy living alone in such a small apartment. He told me to inform my landlord. I explained the situation to my landlord and he got upset and started raising his voice and saying it was my problem, etc (then rambled incoherently in Shanghainese and closed by saying all foreign people were 'fan si le' ???). Anyway, I get back on the phone with my connection at the water company, who told me the company is going to arrange an inspection to happen Monday. So we will see what happens.
Actually, I was pleasantly surprised. The water company has an English speaking reception for their phone service (huge help!)

Thanks for the help!
