Is a vacuum breaker required by code at hose bibbs (outside faucets)?
Monday, December 30, 2019
Yes, it is required at all hose connections, including at an inside laundry sink faucet if it has threading for a hose connection, except for water heater drains and washing machine faucets. Here’s the excerpt from the Residential Edition of the Florida Building Code (FBC 2902.4.3), and the International Residential Code (IRC) is similar.
