防回流阀

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).

What plumbers must do

\r\n

\r\nIf you've determined the site's hazard rating as low, our 20mm and 25mm water meters already have a simple backflow prevention device in them. If the property's water meter is larger than 25mm, you'll need a separate backflow device. Find out more about meters and metered standpipes.
\r\n
\r\nYou must advise the property owner of the backflow requirements and install a backflow prevention device appropriate to the property's hazard rating. You must also tell the owner if the device needs to be tested each year.
