When was a vacuum breaker first required by code for hose bibbs?

Tuesday, December 31, 2019

We know that hose faucet vacuum breakers are an annoying safety gadget for many homeowners, but they have been required for quite a while now. Because we were not sure precisely when it was first added to the code, we asked the code specialist Jerry Peck—but he couldn’t pin it down exactly either. 

    Prior to the statewide Florida Building Code in 2002, there were multiple codes used by different jurisdictions around Florida; primarily the Southern Standard Building Code, but also the National and South Florida codes. Jerry found a citation in the 1988 Standard Code that “adequate protection shall be provided to prevent possible backflow or back siphonage of an unsafe or potentially hazardous fluid or material into a safe water system,” but suspects that it may have been in place in some areas even sooner. Like we said, quite a while now.

    To understand why these pesky fittings that gush and spray on when they fail are so necessary, see our blog post What is a "cross connection" in a home's plumbing system?
