预防回流

Requirements and registration\r\n

'Backflow' is water that flows backwards into our pipes after a property has used it. This water may carry contaminants that can harm people's health. That's why backflow prevention is so important, and backflow prevention containment devices must meet our connection requirements. We have a guide that provides information for backflow prevention (1MB) containment and a collection of frequently used Backflow prevention terms (66KB).
