摘要

For most of us, plumbing is out of sight, out of mind — until a problem arises. Overflowing toilets or clogged drains are usually little more than inconvenient and messy, but potential bigger problems do exist. If left unchecked, these can create public health hazards. Imagine this. It is a searing summer day. You have just come in from a run with the dog, and you are parched. You turn on the tap, desperate for the cold wetness to soothe your throat. What comes out of your faucet, however, is cloudy and almost gray, with an oily, rainbow sheen on the surface.
